Recording video to h.264 codec on Evo?

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 ?

they cant do a whole lot with any camera settings till the source kernal is released. Who knows when that will be heh

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.
Scott"

Thats what I wondered to, but I guess not.
We are using one of our employees phones he bought from Sprint. All of the drivers and software are stock and from HTC.

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.

Good god, our Evo sucks mighty ass in the 720p category.

Camcorder hack for (Much?) better video recording

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!

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.

[Q]LG G3 Slow-Motion Camera Quality

Hi, I tried the G3's camera and I'm really impressed by the splendid quality, untill I tried out the slow-motion feature. I know that there's this camera tweak that you have to flash or manually move the apk and stuff
(For those who are looking for a mod that improves 4k bitrate as well as the 1080p fps count: http://forum.xda-developers.com/showthread.php?t=2778570) (Credit for this goes to the developer). But I'm wondering wether there is a camera mod that enables a higher resolution video/camera and bitrate for the slow-mo mode of the G3, right now it's set at 720p at 120fps, but when saved, the file seems only 120p, the fps is great but there's so many pixels and it's a shame for the awesome 4k screen that the G3 is packed with! (I'm not sure about the exact numbers though, could be false) Any help is greatly appreciated!:good:

LG G3 4K Video on AOSP - did it ever work for anyone at all?

A while back CM12 had a patch that enabled 4K video recording. I remember that it even worked SOME of the time, but mostly it showed to be recording without saving anything. Currently on CM12 and Blisspop the option is again removed - probably because it was buggy: review.cyanogenmod.org/#/c/103494
I've tried many different camera ZIPs from other manufacturers (Motorola cam, Lenovo cam) but they do not appear to enable 4K either.
I tried playing around with the media_profiles configuration file, uncommenting the 4K profile. This does enable 4K video recording - even saving, but the framerate is really bad (<10), both with stock and third party cameras.
So my question: Did anyone ever get smooth 4K video to work on AOSP? If so what was the combination of software used?

yes it did work for idiots who;
1) flased xXcameraXxfix_AROMA_VIPERPRO_v4_FAKXDA_LIKE_SUBSCRIBE_DONATE_YOUTELLMEBUGS.zip
2) set the resolution to 4K
3) shot a video
4) never realized it didn't even save, even if it did, it was lagging between 5 and 15 fps
TL;DR
no, it did not, i have flashed all the 3rd party crap from random monkeys claiming they fixed the camera on aosp promising stock quality
to those who come in here telling me it does, provide proof or gtfo

BUT, is there any non-stock ROM with STOCK camera quality? No 4K, I do not need that, only 1080p (60 fps or 30).

Nope Coki4, unfortunately Tehosiris is right: with the HTC cam and resolution "fix" I can record in 4K, but it is still way too low framerate (15 FPS or worse).
Voterx: To me 4K is most important, hence the thread. If i want proper pictures I take my DSLR anyway... 4K video is something that is really a beautiful thing if you have the screen to display it. There is a huge difference between 1080p and 4K.
To me it is starting to look like the camera driver in AOSP source is just not able to push the pixels?

Snap camera does it. I have also found that snap camera takes as good, or better in some cases, pictures as the stock camera.

What are you doing to get those file properties? Want to check what my jerky files say..
edit:
Properties here also shows 30 fps, but the video is jerky as fuuuuuu* - i guess it is saved "as" 30 FPS but it just drops a bunch. Yes it is 4K but def not 30 FPS, even if the file shows it to be (for me).
but.. if it is smooth for you I want to know your exact rom details so I can try to achieve my holy grail.

can one of the digital cowboys upload these fabled 4k videos shot on aosp?
i still yet to see a nonstock 4k video that doesn't lag like ****
@geekmystique the jerkyness doesn't show in properties, they are just the same as regular videos, you can check the properties in root explorer or any other file explorer.

your 2nd screenshot shows that the 4k video is in 59.9 fps, now THAT i'd like to see.
bending physics with an apk eh? :laugh:
edit: judging from the amount of silence after the bigface comments, i assume it takes an awful lot of time to upload the fabled 60fps 4k video (translation: someone is full of **** and/or clueless)

Let's not make this into a flamewar of sorts.
This is a video I took of my hand waving in front of the camera, whatever the file info says, it is not 30 FPS - by far, it is dropping frames like crazy. The file properties say 30 FPS in MPCHC, but windows properties shows the truth: 18 FPS.

i suggest you take a look at the camera comparison post here on xda, showing stock / moto / htc / whatever side-by-side
there is no such thing as stock quality on non-LG driver backed software
Anyways, i'm absolutely on geekmystique's side here, i've had multiple people giving me lectures how i need to flash xyz.zip set ABC settings to DEF, align my device towards Mars, count to 7 and stand on my left foot to have AMAZING STOCK QUALITY PHOTOS AND VIDEOS.
Guess what, i've done all those steps, flashed all the zips, pirated all the ****ty apks and gotten nothing but disappointment.
Thats why there is sarcasm towards these 'BUT MY AOSP CAMERA IZ BETTUR BRUH YOU SUK', when it's clearly not. Hell, half of the conversations ended at 'WHO NEEDS 4K' or 'I DONT NEED CAMERA ANYWAYS' which is ridiculus when it's these people giving lectures on how to flash stuff they don't even know what it contains.

If so.. Please post the video - my video that I posted also says 30 FPS, but it stutters like mad. If you can get better video I would be really happy to know.

Guess the aosp camera is just as good as stock boys are back in their caves.

[MAGISK][MODULE] HEVC Recording Enabler v0.3

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:
Code:
v0.3
- Change the audio bitrate from 96 kb/s to 192 kb/s
- Change audio codec from HEAAC to AAC (ha better audio quality for bitrate major than 128 kb/s)
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
- 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
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
Source links:
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

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

If you use the half bitrate file you should get again better video quality but also smaller video files for the same length

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
Mod edit - Link to download added: https://gitlab.com/eathtespagheti/o...a8f64ddc6d0dbc/oneplus6-6t-hevc-recording.zip

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

Tried 1080p60 just recording my keyboard on the floor. Same results. The bitrate is the same.

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.
