In the HTC camcorder even you choose the encoding method as MPEG it would save the file as 3gp, but with this it will save the file as mp4. I had to modify a few smali files to get it working.

This is only changing the extension. The videos are already being recorded in an mpeg-4 stream, they are just being created with a .3gp extension. This is really only for people who need the extension to be mp4 for some specific reason.

I have tested this a bit so be sure to back up your original HTCCamera.apk just in case.

Download it here.

As you can see below, nothing with the encoding has changed.




In recovery:

mount system
adb shell
mv /system/app/HTCCamera.apk /system/app/HTCCamera.apk_
exit
adb push HTCCamera.apk /system/app/
adb shell
chmod 0644 /system/app/HTCCamera.apk
exit
adb reboot

Does this also change the audio codec to something useable like AAC? Love your roms, use them and enjoy them heavily, mp4 usable on the ps3 would be amazing!

No, I can't change how its encoded. This is only changing the extension. The videos are already being recorded in an mpeg-4 stream, they are just being created with a .3gp extension.

Can you make 720p or any other recording resolution do > 30fps. The framerate on 720p is garbage.

Nope, I have no idea how to do that... This wasn't very difficult, it just took some digging.

720p at 30 fps is fine. The problem is that we aren't hitting that fps.

Can't squeeze blood from a turnip, and you cannot make hardware do something its unable to with the current OS.

As for aac audio streams, I doubt this phone supports it. I know where to change it, but so do a lot of people, esp. on the N1 forums. I've not heard of a successful case yet. Not even CM6 does it.

Before i flashed to your newest rom, i decided to try this on the existing rom.. Took footage of my room and what do you know, streams to the ps3 just fine.. But i pressed select and the Audio had dolby digital in it, meaning sound worked.. I took another video but this time played a song. Tried it and it worked!!!

This is AMAZING news! Before i had to sit there and convert the videos and they usually ended up not even working, now using PS3 Media Server, they work no problem. Thanks so much, you should take a look for the Evo guys and get it fixed for them as well if you can, i have a feeling all my evo owning family members are going to want in!

If you folks want to see if the aac audio codec will work, you can try this. Install it via clockwork, but make a nandroid.

Well, i look forward to this .MP4 mod cooked into your next Rom, also, the recent WIFItether AP mode. Which by the way works great on your #2 Rom. Great Work.

Is it possible to record videos that use H.264 when res set to 720p?it should improve its 720p quality.it can only set to WVGA when it uses H.264.
