[DEVS ONLY] Nexus 4 camera recording v0.2 (AVC high profile & LEVEL 4) (60FPS)

[Shaky156]

Hi releasing a quick kernel to test the camera quality
Compiled for Android jellybean 4.2.1 & 4.2.2
Ive tested it needs more modified but ive activated high profile & level.

For testing the boot.img boot in fasboot mode in terminal via fastboot boot boot.img

Test and post results thank you

Log outputs this
OMXCodec: [OMX.qcom.video.decoder.avc] AVC profile = 100 (High), level = 51, ive changed kernel and set the level to 4 for now.
High profile avc h.264 has been achieved along with changing of profile level upto 5.1.
Now my focus/attention is on FPS attempting to achieve 60FPS recording

This is a quick kernel based off motleys for testing purposes on camera quality so thank you motley!

Interesting.
So this kernel has everything from Motley, plus your Camera modification?

And what kind of feedback do you want us to report?

Log tells me its set to high and level 4 so thats a definite but i might need to modify more to get it running good also ive attempted to get it running at 60fps camera does look smooth to me, but need confirmation of camera quality and smoothness improvement, didnt have time so couldnt check the fps of video i made

Since it is for testing a I recommend a

"fastboot boot boot.img" to test without flashing, just in case something goes bad, then you just need to reboot.

 

[nick34609]

Flash went well. Going to try some pics and video and then compare to stock and let you know. Colors need adjusting, does this support gamma changes?

It does support gamma changes. Just restored my display settings. Now to test out the camera.

Image quality looks good. Recording looks smooth. How can I check the fps on the video?

If you're using MPC HC just press CTRL-J during playback, I'm curious to hear if frame rate is close to 60, it will be very nice breakthrough, in theory, hardware supports this...

1080p video is at 30.77 fps. Let me take a 720 video and check that now.

720 is at 27 fps.

Okay thanks for testing ill attempt the fps again, but the encoding/decoding high profile level 4 has been achieved

2 things have been achieved so ill attempt fps

Since ive used motleys kernel you can use motleys as a direct comparison for video quality etc

Actually is it possible to enable HDR video? Or is it a ROM-level thing not kernel?

 

[halluci293]

This is awesome news if it works. I followed this thread: http://forum.xda-developers.com/showthread.php?t=2039553
but they seem to have reached a dead end in terms of actually improving quality, rather than just file size. I'm curious how you managed to enable high profile AVC, since the last I heard, it seemed to be locked in the driver somewhere (http://forum.xda-developers.com/showpost.php?p=35804435&postcount=160)

Also, I don't think there's hardware support for 60fps 1080p, only 60fps 720p.

I did set thw framefrate as 60fps can someone use a modded profile.xml and test fps??

I flashed the XML from the other thread and it actually lowered my fps to 24. And it made video look choppy for some reason.
