This question is for developers. Can devs replace crappy compression codec on Evo recording cam to record with h.264 to improve quality of vids we shoot by far. Current cam codec is SO bad that 720p does no justice for the cam. Basically in my view camcorder is useless. H.264 would change the whole game for this phone. Would love to see the rom with h.264 video camera codec. Would any shead some light on this ?

Do you even know what the current cam codec is?
It's MPEG-4 Part 2 (generally referred to as "MPEG-4"), which is most commonly known for it's implementations in divx/xvid.
It's not as trendy as H.264 (aka MPEG-4 Part 10 and/or AVC), but generally quality isn't what people take issue with when choosing h.264 over MP4 - it's filesize. When you get into higher resolutions with higher bit-depths, being able to compress a stream allows you to work around issues with slow write speeds.
I think you really aren't familiar with video encoding or codecs in general. You should educate yourself a bit more before announcing that a simple codec change will resolve the camera woes with the Evo.
h.264 is currently patent encumbered, which is part of why you don't see it implemented so widely.
Swapping out the codec isn't going to be a magic fix to improve this camera. It's limited by it's very design. Consider the 720p video a novelty and try to only shoot in situations with lots of ambient light and it'll be far more usable.

I agree with you. But x.264 is not involved in any patent issues, is free, and works very will with the best container format available to date... mkv.
Now the phone will do hardware decoding of x/h.264 but you are right, I don't see any advantage other than the smaller file size. You are right again, on one of those P labeled cams the h.264 stream is much smaller than that of mpeg-2/dvd or others so it works well on those crappy hardware writers.
Changing the encoding profile of this camera would not fix your issues OP.
I've never seen bad quality from h.264 codec but then again i agree i have not research enough on the codecs comparison enough but that's why i'm asking. I just know it looks horrible. Somehow camera pics are acceptable. Thank you for the input.

I could encode an h.264 video in a low bitrate and low resolution and it would look bad. The codec is only one factor involved in the end result. Different codecs can squeeze better quality video into a smaller file size but it comes at the expense of CPU use and other bottlenecks. In this case I don't think the choice of codec is what is holding back the video. It's probably more about processing power and overall architecture.
I'm not sure that implementing x.264 compression for the EVO would solve anything. From my experience in order to have better quality with h.264 over h.263 it requires much more processing power due to the higher compression complexity.. This would all have to be done real time by the phone.
With the great hardware being sported by the EVO I wonder if a more unorthodox approach could be implemented to attain the highest quality possible.
How about this:
Capture video using a real time lossless compression. Maybe huffyuv?
Once captured let the phone recompress the source to x.264 or whatever via a background service or at a scheduled time like 3am or something
Maybe via this method a higher frame rate could even be achieved?

Uncompressed [email protected] with 8-bit color would be something like 45MB/s. (That's excluding audio.)
No current SD card supports those write speeds.
I'm not sure that you could losslessly compress it down to something that'd support even a class 6 card.

Eeeeek!!
I checked it out and you are right on the money.
(8 bit @ 1280 x 720 @ 59.94field = 105 MB per/sec) / (2.33:1 huffyuv) = 45.06
Still I wonder if better video quality could be achieved via a capture now (large file size) compress later (small file size) solution.
Certainly, considering your well taken point, we would need to keep things within the requirements of the EVO's hardware (sd card included). Probably would need to keep the data rates within the EVO's stock microsd specifications in order for it to be viable for everyone.
The iPhone 4 can record in h.264 and its processor isnt *that* much more powerful than Snapdragon (and the camera is similar--same company, same sensor size, same features, just 5MP instead of 8MP). What it comes down to is lazy coding by HTC
I don't know if you guys have looked in the build.prop file but the settings are in there. I just don't have alot of time to play with them but here's what's inside. Sprint/HTC changed the line in 1.47,ro.media.enc.vid.m4v.bps, to 8000000 from 6000000 on 1.32, so I'm guessing that's how they upped the Mbits in the upgrade. I could be wrong and the change may need to be in the kernel also but play with them and see.

I may not be a...
developer but when you are talking about codec you are talking my language (I am an editor). H264 isn't that great itself and won't make the EVO's footage look any better yeah you get some more detail out of the H264 but the real reason the camera doesn't look as good is the variable fps in different lighting conditions. The variable kills it. The cam should be fixed at 24fps or 30fps. If that can be done you will see a major difference. I'm not sold on the white balance either. Also I would love to have h264 but the difference in the two is compression. H264 is better but again FPS is key.
I agree as well as most of the other people that h.264 won't help by itself.
Though one thing it would help with is allowing to bump up to a higher bit rate and or FPS and still maintain speeds sufficient for Class 2 SD cards. So, even though it won't do anything by itself, it will help in that you could in theory record higher quality video to your phone.

Das troo, I emailed Omnivision about the issue, they said that their Evo is great there, and that I should contact HTC about it and had said they created the driver/software for it.
"Hi Steve,
I’m sorry to hear that you are experiencing issues video performance. The HTC EVO we have here works great. OmniVision only makes the sensor. HTC makes the drivers and software that run the sensor. Unfortunately, you will need to contact them with any issues.
Sorry, I couldn’t be more help.
Scott"
Then I had asked them if they have any samples they used. And sent me a video they just recorded.
"We just went outside and took this simple video. Hope it helps.

Good god, that video sample is hideous! Look at this video comparison done between the Evo and the iPhone 4 in the exact same scene. There's just no competition between the two.

I know that we can get better quality video recording out of the TP2, with the first WinMo phone shooting WVGA @ 30fps with the exact same hardware (minus cam module), I'm excited to see if someone can work their magic to incorporate better recording from the TP2.
Anyone else?
Cyph
I too am curious about this. I have actually always been curious as to whether the video capabilities are more software dependent or hardware... Though if the phone is capable of displaying the video on the viewfinder at WVGA at 30fps it should theoretically be possible to record at that quality. Anyways, we'll see what crops up later
Not at all

Unfortunately the above statement is not at all true. Recording depends heavily on the camera hardware in terms of possible frame rate at a given resolution. Furthermore real-time compression and encoding is a significantly different proposition to the CPU than decoding and playback. This is not to say the TP2 hardware may not be capable of doing better than it does, just that playback capabilities are no indication.
Dennis
Like I said, I don't know how much the camera module affects it. And what I meant by theoretically is that if it can display that on the viewfinder at that res then theoretically it could be recorded in raw format (as long as the transfer to the memory could handle the speed), but it would not be practical by any means. But if the x2 is capable of it and IF the ONLY difference is the camera module, and IF the camera module is just the sensor and no graphics processing then it could possibly happen. And I'd love to see it. But neither am I going to hold my breath.

You see minutes 4:29 ..... But WVGA recording resolution is 720x480? or 800x480?
Thanks
The Xperia X2 has the same CPU as the Rhodium and in theory the video recording abilities can therefore be ported. The drivers for video recording must be extracted and put into the Rhodium ROM.
Even if the Rhodium camera or drivers doesn´t handle WVGA widescreen recording it´s possible with some development work to use better encoding drivers - i.e record VGA but let a good MP4 encoder with good quality do the encoding job (i.e replace the original HTC video encoder with a better one).
In this case the original HTC camera application is retained but with replaced encoders. The user only sees a quality difference - the handling of the camera app is the same otherwise.

That's definitely be a good thing. Maybe it could even up the fps a little bit.

Well if we can get someone on that I'd be willing to pay (big - ROM COOKERS LISTENING?? :-D ) for the capability to enhance the video recording capabilities. I just need an additional 10 fps and maybe another 200 kb/s bit rate for excellent video. That would make the video recorder to 30 fps @ ~ 1Mb/s..niiice.
If they can accomplish WVGA or even D1 (720x480) that would be cool too (or better).
I wish I had the skills/tools to do that, I'd be all over it like white on rice! LOL
Cyph
Personally I don't need 30fps (though it'd be nice). I'd be happy with a video standard such as 23.976fps or whatnot. 20 does look stuttery. Just a few more would fix that. Well. Let's hope someone looks into it. Though it might be necessary that we wait until the x2 is actually released
Hey there,
In my experience, the Desire compresses the hell out of all recorded video, which makes it blurry. My girlfriend ran a marathon a couple of weeks ago, I recorded parts of it but people's faces looked like they had been blurred out digitally, or as taken from a Japanese 00's horror-flick.
I have the highest quality setting activated, as well as the MPEG4 encoding type selected. Still the Desire saves videos in the outdated .3GP-format that I had on my Sony Ericsson's six years ago, instead of as .MP4.
The file size of one minute of recorded video is about half the size of the same recording on my Nokia N97, and unfortunately, the quality is about half as well.
Is it just me, or does the Desire compress video way too hard? And why aren't they saved as .MP4 when the MPEG4 setting is on? Is there a tweak to decrease the compression ratio?
Thanks!

Neither .3GP or .MP4 are video formats - they are container formats (see here).
If you select MPEG4, it will be saving as MPEG4 within the 3GP container.
As to the actual recorded quality, I can't really comment as on the few occasions I've used it to record video, it looks ok to me.

Dave

We're supposed to be getting an update to support recording at 720p (as well as DivX). HTC announced this before the Desire had shipped, but has been curiously silent on the matter since then.
I did tweet @HTC about the lack of a DivX update, but @HTC only wants to respond to trivial nonsense it seems.

Yeah I noticed they are quiet on that at the moment.
I wonder if they are planning it with the 2.2 update maybe?
hmm, I got a feeling they have trashed the 720p video quality update.
it has been silence about it for a long time:\
Froyo 2.2 will have the 720 option it was mentioned in the detailed Google IO paper. Along with better gmail. End calls with the power buttons. And app updates upposed to OS revisions.
The max option records at 2Mbps. You can get decent quality from that, most YouTube vids are far far lower. The framerate however differs depending on the ambient light but anything plus 15ish looks fine.

Is there even a "max" option for the video camera? If so, where is it located? I can only find a quality setting for the still camera. A 40 second video clip recorded with my HTC Desire is approx. 10MB. That's very far from 2 MB per second?

i use format factory free to download and only program which rips bluray rips .mkv to make it work for htc desire. You can choose from so many profile and test the settings which suits best to your mobile i believe res setting for htc desire are 400 by 800. i can send you setting i use. I ripped avatar blueray rip 8gb to 745mb with awesome quality. Give it a go you wont be disapointed and it supports subs. it basically supports all formats.
i just used MEGUI and it's iphone preset but left the res as 800xwhatever. AAC audio.
worked fine.
Format Factory sounds great with a whole bunch of the 23 reviews saying it has a trojan in the installer and also automatically installs the Ask Toolbar!
i myself megui for ripping but format factory is way easy to use. Megui is bit complicated program i do use it for ripping you can crop colour correction etc but megui takes longer to rip. i have found format factory to rip 720p rips perfect for my nokia n97 mini and desire.

I believe it was back when the Desire was the Bravo - there was alot of talk of 720p recording and the fact the hardware supports it
Must have ROOT
EDIT**
I have just uploaded V2 of my profile - I have lowered the Bitrate slightly and changed from 3gp to mp4 file format.. I have also enabled 720p for the front facing camera - Let me know if the lowered bitrate still performs as well.
Folks,
This is my edited media_profile.xml for far better 720p recording.. thought I would share it..
I have upped the bitrate from just 1MB/s (default)to around 4MB/s.. for me, it is clearly better when played on my Monitor or Television.. smoother, more detail and appears clearer.
I have tried a higher bitrate but found this to be a good balance between size and quality.
I have also tried editing the xml for 1080p recording but cannot get higher than 14fps when recording so have not included it..
to install, just unrar the media_profiles.xml and copy it to /system/etc and reboot.... REMEMBER TO BACKUP YOUR ORIGINAL FIRST.
This has worked for me, but if you end up in a boot loop, pushing the original file should fix it.
Hope you enjoy it.
Bracken
Do you have a comparison video or anything? This is the kind of thing I want to see before flashing.
Nice find!
I can see the difference just watching play back on the xoom! Alot smoother...ill check out the HDMI when I get home.
Will this work on any Android device? Say my DX? I take way more video on that.

have you a stock Kernel or Custom Kernel + overclocked CPU?
Works well, I have a similar hack for my Nexus.
Easy and simple improvement for video recording.
Using Hammerhead 2.1 & Tachi OCed kernel.
@bracken21 = does this affect the still camera picture taking?
Thank you very much, great mod.
Hi,
@Sergio PC -This does not affect the picture quality only the video..
@twister_65 -I had this completely on stock 3.1 with stock kernel and worked fined.. I'm now running it with Hammerhead 2.1 & Tachi OCed kernel.
Even OCed @1.6, when I enable 1080p recording there is no increase in FPS, it stays at around 14FPS.. I presume the actual sensor is not capable of [email protected]
@mradlauer - I have no idea if this could be done to the DX, I presume so, but what resolution, bitrate and FPS would depend on the device.. if its anything like the Xoom, putting in an unsupported profile may result in a boot loop ?
If there is interest I can upload another profile with settings as follows... but I find it pointless as 1080p @ 14fps is unwatchable.. I have tried increasing/decreasing the Bitrate but still only does 14fps.
1080p 6MB/s @ 14fps when high quality selected.
720p 4MB/s @ 30 when low quality selected.
720p @ 30fps for front facing camera.
Thanks

Nice find.
Pretty easy to increase or lower the bitrate yourself.
I personally upped the bitrate to 35MB/s for 720p.
Adjusted the 480p resolution to 720x480 @ 20Mb/s for quick and easy converts straight to dvd with no resolution changes.
Adjusted the audio bitrate to 256kbps, sample rate to 48khz and enabled stereo recording.

35MB/s is 2.1Gb per minute - that would give you around 15 mins recording on 720p on 32gb card. Plus with the size of sensor and optics, im guessing you wont see quality increase above 3MB - 4MB/s and even that is asking alot of the camera due to the noise levels and lack of light/detail passing through the small plastic lens. As for stereo recording, I thought the Xoom only had 1 mic ?
Being that bluray movies are around 34MB/s.. I think asking a small plastic lens on the xoom to do that a little much. Also the tegra 2 is listed at only supporting 20Mb... did you also amend the codec maximum bitrate as its currently set to around 5MBs.. if not, you will actually be recording @ 5MB/s.. Also, is 35MB/s over the write limit for xoom internal storage.. I could be wrong but even a class 10 cards only write at around 10MBs and reads @ 30Mbs ?
If you want to try 60fps, you would also need to amend not just the recording values but the codec preference and possible the memCap too.. ive not tried it yet, may give it a go.
Im not trying to have a go at you, just stating that your filling your xoom up for no reason... in a long winded blurbing kind away.. not had my coffee yet..
As for the problem with front camera zooming in on 720p, nothing I can do about this, that fix would be above my head.. My guess is that the google camera apk would need amended for 16:9... my knowledge of Android goes as far as this little dirty hack.

bummer on the zoom and front face stretch problem... Gonna have to revert to stock unless fixed in the future... Will subscribe for updates in case. Nice for folks that don't mind those couple details though

Hi, just revert to version 1, it keeps the front camera stock and rear camera is improved..
As for the people not being able zoom, you can't zoom in video mode using stock... well mines never has.
I wish I knew how to port the camera front the Samsung 10.1 tab, does any one know how?
Cheers

OK,I guess most experienced people would know about this,but still,here goes.
If you have a root browser(downloadable from play store),then you can edit the media_profiles.XML found in system/etc.
This can be edited to get your video recording from 640*480 @ 24fps to 720*480 @ 30 fps.(This is excellent for viewing on the wildfire S.)While technically higher resolutions and frame rates are possible,the stock Gingerbread camcorder app doesn't seem to list it in settings.Plus,higher frame rates don't work properly for me anyway.
So,here's how to do it :
In media_profiles.XML,under encoder profile high, change the width to 720,height to 480 and frame rate to 30.
(I'm not really sure about the following part,although no harm in trying.I'm just not sure whether this is really necessary).
Under each of the encoders below that (h264,h263,m4v) make the maximum height and width to anything you want above 720*480 and frame rate(if below 30) to 30.Max bitrates can be changed too,if you want.
I think its possible to change the camera encoding quality too,although for general day to day purposes,It's not too useful.
I'm open to any suggestions/Improvements if found.
Thanks for reading!
have u tried it??

Well,yeah.I don't see how I could have known this otherwise.
Actualy on the stock 2.26 these values are 720/480/24 by default dunno what rom were you testing this at.
If you do it once,even if you completely reset it,it goes to 720*480/24.
Maybe it's an update by HTC,as initially it's supposed to be 640*480/24.
Anyway the main thing is changing the framerate to 30 fps.....really improves overall video recording.
Hi, I've made a Magisk Module that enable HEVC / H265 Recording in the stock camera App.
This module enable HEVC/H265 video recording on OnePlus 6 and OnePlus 6T.
The bitrate values are the same as H264 and the HEVC code it's enabled for all the video profiles that previously used H264.
The audio codec it's still AAC and the audio bitrate doubles from 96 kb/s to 192 kb/s to get a better audio quality.
I've also made a diffrent fork that use half of the bitrate (and therefor half the space), it also keeps the original audio bitrate and change the audio codec to HEAAC to save space without losing quality
Why should I use HEVC instead of H264?
Basically, HEVC provide the same quality as H264, but using less of helf the bitrate, this means that you can record videos with the same quality but using less space, or, if you're more inclined to that, record video that use the same space but with better quality (less compression, therefore less artifacts and more details overall). This is the theory behind HEVC, pratically speaking I've noticed some differences, other users havent, so I guess the best way to find out if it really works it's by letting my beloved XDA users test this mod.
More info about HEVC on Wikipedia
Compatibility:
Should be compatible with every ROM since the mod change files in the /vendor partition, but I've tested only on OOS Open Beta 33
Original version changelog:

v0.2
- Add HEVC support for all configurations previously used with H264
- Add HE-AAC support in HEVC encoded profiles
- Remove config files that doesn't affect the mod result
- Update HEVC encoder configuration to match the same limits has H264
v0.1
- Initial release
Half-bitrate version changelog:
Code:
v0.3
- Change the Bitrate multiplier, now it's 0.38 and the effective bitrate (checked on 4k60fps) it's 60.9 Mb/s
v0.2.1
- Change the Bitrate multiplier, now it's about 0.4 and use about half of the original space
v0.2

v0.1
- Initial release
Download links:
Stock bitrate (same space, less compression, better quality)
Half bitrate (half of the space compared to original, quality should be similar)
For older version check the releases in the gitlab repo

Stock bitrate
Half bitrate
How to check if it's working?
Shoot a video and then check which coded it's used, you can use this app
Let me know if you see improvements or not, thanks in advance!
Can you tell if this works on Stock OOS only or Custom ROMs too? Also on a side note, what's the benefit of this module? And I'm sure someone else will ask it too, but does this work with the Stock OOS Cam only or it will work with Gcam too?.

In short, HEVC it's a coded that allow better picture quality compared to H264 (the coded used by default on OP6/6T) when using the same bitrate (occupying the same memory), I've made a short explanation in the readme of the repo with a handy chart about compression ratio comparison with H264
This module enable HEVC on stock camera for sure, I haven't check on GCam since it already has a built-in HEVC encoder, but I don't know if when disabled uses H264 or the stock defined by the media_profile.xml

How to find it withing Magisk Manager? Just search HEVC?

What exactly changes by enabling HEVC recording?..
Have no idea what that is...

If you use the stock bitrate Module, you get better picture quality in videos for the same file size
If you use the half bitrate file you should get again better video quality but also smaller video files for the same length
Didn't work for me 10.3.1

I recorded a 4k60 frame video with the stock camera for 30 seconds, then installed stock bitrate, recorded, then uninstalled and installed half bitrate and all three file sizes were the same and looked the same.
Then I tried 1080p60, same results with all three. all the same file size and quality.
Is there a special way to enable it besides just flashing via magisk?

Right now I don't have enough posts to be able to put links in thread, but I should be able to put links in replies if you ask me the download links, otherwise check my github / gitlab account and you'll find the source there, the username it's the same as here on XDA

Were you filming the same scene? A lot depend also on what you were filming, imho the quality difference it's noticeable only when watching the video in a good monitor or when you are editing, you notice that there are less artifacts in the details and the overall sharpness it better, but on the phone itself it's impossible to spot the difference. To be sure that the HEVC it's enabled try checking the codec info on the video, you can try with this app and in the format section it should say HEVC if the mod it's working, otherwise it will show AVC

Yes, it says HEVC but the thing is I recorded stock camera 4k60 no modded camera, your stock bitrate, and the half bitrate and all 3 files sizes are the same.
I used a tripod and recorded a black sheet for 30 seconds.
Is there a trick? I could really use the half bitrate. Haha damn life saver.

I think it's because the bitrate it's variable, so when you are filming something that's not changing and doesn't have much details in it (like a still black sheet for 30 seconds) the camera used the lowest bitrate possible to get that video anyway, try filming something in in movement that you can reproduce, I will do some tests too

Ok I've checked on my phone too, same bitrate between HEVC and AVC, maybe I've to change some other parameter in order to change the bitrate, I will post an update here when I'll have a free minute to recheck the files

I flashed your module and its working. If you can do anything with the bitrate it would be appreciated
Hi, thanks for the mod [emoji106] just a quick question for you. Is it possible to add Hevc to single shot pictures as well?
As you should be able to get the same quality pictures for half the size.

Well seeing as how HEVC stands for High Efficiency Video Coding.... No
But there is HEIF, that's what you want.

After like two full days of trying I havent been able to reduce the bitrate, changing the default parameters seems to not affect in any way the camera settings, still choose some values automatically that are even different from what's written in the original config file without mod

Well, AndyBury has a point! In fact the HEIF and HEVC are strongly related, and according to Wikipedia "The HEIF specification also defines the means of storing High Efficiency Video Codec (HEVC)-encoded intra images and HEVC-encoded image sequences" which surerly means something, but tbh I'm not so sure what's this something. Anyway I was already planning to trying enable HEIF via media_profiles, but seems something more complex than just adding a codec in a list, the only standardized usage of HEIF right now seems to be the one used by Apple on iPhones and Macs, I think that until Google doesn't implement in some way HEIF photos with camera we can't do anaything about it.
