GALNET's fix for choppy 720p recording in CM7/MIUI

Somebody knows what the bitrate is for 720p videos in Samsung roms?

JVP:

quality = 'high'
fileformat = 'mp4'
duration = '60'
video codec = 'h264'
bitrate = '10000000'
width = '1080'
height = '720'
framerate = '30'

On XXJVP rom the bitrate for recorded 720p videos is ~12mbps

When on cm7 i found out that playing with different cpu governors influences the 720p choppiness more or less as well. Conservative governor messes 720p up, while on demand improved it....but didnt get rid of it.

Havent tried galnet's fix or their latest miui but on a pc the reported bitrate of 720p material from SGS is ~12mbps + ~2mbps audio track

Im on Doc kitchen jvp rom now with SGS2 camera app and works butter smooth. Its not just the recorded material that is smooth but also when panning around just after starting the camera app is very fluid (as opposed to cm7/miui)

Thanks! I also found out about this workaround by looking at the patch to 7.7, which diff showed a change from 12,000,000 (in 7.5) to 8,000,000. I don't recommend lowering that value to 5,000,000 because more kb/s = smoother video. Though I noticed something strange:

1. After upgrading to 7.7 (8,000,000 bitrate), I tried catching a HD video with MiuiCamera, that produced a very choppy video (still...) with unsynced audio.
2. I catched another 720p video with Android Camera, and the result was better, though I don't like the m4v container for the output files.
3. I used MiuiCamera to record another HD video, but this time it was perfect!
4. The following videos shot by MiuiCamera were still as good, even after a reboot, for now.

So, I don't think we require the Camera.apk to make MiuiCamera.apk work as it should. There is probably something about the governor or kernel ticks (HZ) which is clashing with the 720p recording. For the "record" (lol), I'm using the smartass governor on Zach's NEO 08, while scheduler and OC/UV don't seem to have a high relevance.

Also, why does MiuiCamera produce a 3gp video for 720p recordings, while it's clairly specified to use the mp4 container? I also used Avidemux and ffmpeg to check the video, and it has a 1280x720 resolution with H.264 and AAC codecs. So, why the 3gp extension?

EDIT: I forgot, have you understood why the m4v max bitrate was lowered to 2,000,000 while stock JVP has 12,000,000 ?

Any other feedback aside from this comment?? I would appreciate if you guys found a way recording a nice 70p vdieo from my phone

Currently on CM7 recording is bad, doen't work properly. Users from galnetMIUI forums claim that recording works fine with Chameleon release. Fix is not public, so... CM7 hasn't got proper 720p video recording

It isn't the unique change...

Probably some more changes in the kernel also.There was a thread on their forums, where a user said thar 720p recording works only with default kernel, while with custom kernels doesn't. It's quite annoying, using a stock/custom ROM based on official looks really slow for me, using CM7 feels really good and fast... but with the loose of recording, which I really need for my little girl's unique moments in life recording. The High setting for camera in CM7 makes recording possible, there are very small glitches sometimes, but it's a pitty to not use it a fully potential.

Thats not a "fix"? It just lowering the bitrate which means less smoothness and worse quality.

That aint a "fix" for the problem to me

Actually looking at the xml file mentioned in the first post, in the case of latest nightly of CM7 the value is 10000000. But, keep in mind that the post is from june, and in the meanwhile the real fix came with galnetMIUI chameleon (or something) which is later. So, they must have figured it out in the meanwhile...

worked for me

Worked for me.
I decreased HD bitRate from 10000000 to 5000000 bps
also decreased HIGH bitRate from 3000000 to 2000000

my video is now playing quite smooth.

Thanks

is this applicable to galnet miui weekly?

screwing around with the lgcamrecorder app settings may help?

on HD i' 10000000 too, but had ploblems on recording. record in format M4V, but look mediaprofiles it wrote as MP4. why it record different format?
