New codecs for TCPMP

[Max Taylor]

I run moto Q. The best way to watch videos and listen to music is to use TCPMP. It opens a lot of formats that standard WMP doesn't have codecs to. But TCPMP cannot open videofiles shot by moto Q. It contains audio in QCELP format, and TCPMP says there is no QCELP codec...
Question: where to get QCELP codec for TCPMP? If we have it we will manage to play fullscreen video shot by moto Q (standard WMP cannot do that either).

p.s. Or is there any way to change QCELP codec into AMR or AAC for example. Then we would have *3G2 file with mpeg-4 video and AMR or AAC sound. By the way I changed the container for the videofiles that moto Q shoots. Now I shoot not *3G2 files but *mp4. But the sound remaines QCELP...

hmmm... Same thing here.
How'd you change to mp4, I vagely remembber seeing something in the registry(?).
I'm also interested in whether is actually changes the format or just the extension name.

I simply changed *3G2 to *mp4 here:
[HKEY_LOCAL_MACHINE\Software\Microsoft\Pictures\Cam era\OEM\MuxCLSID]
"VideoFileExt"="mp4"

and here (for resolution 176x144):
[HKEY_LOCAL_MACHINE\Software\Microsoft\Pictures\Cam era\OEM\VideoProfile\3\MuxCLSID]
"VideoFileExt"="mp4"

So I shoot now in *mp4. Here is the file's options:

Complete name 011.mp4

Here there is the audio codec's options:
[HKEY_LOCAL_MACHINE\Software\Microsoft\Pictures\Cam era\OEM\VideoProfile\3\AudioEncoderCLSID]
"IClass"="{5620ddfa-0d19-463a-ab46-e5d8ef6efd60}"
I guess if to change "IClass"="{5620ddfa-0d19-463a-ab46-e5d8ef6efd60}" into AMR or another "IClass" we would have *mp4 with AMR sound but not QCELP. But I don't know what "IClass" stands for AMR. Obviously {5620ddfa-0d19-463a-ab46-e5d8ef6efd60}" stands for QCELP.

hmmm... Same thing here.
I'm also interested in whether is actually changes the format or just the extension name.

mp4 is a container for mpeg-4 media. Inside we can have: audio (amr, aac, ac3), video (mpeg-4ASP, mpeg-4AVC, 3gp, 3g2 etc.) or both. Instead of mp4 U can use 3gp, 3G2 or any other format. But the container is the same - MP4.
The question is how to change QCELP into AMR like in most GSM phones.
