Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. Run on Sony Ericcson Xperia Ray or may be on any other :)
2. Catch stream with ffmpeg
  ffmpeg -i spydroid.sdp ...

What is the expected output? What do you see instead?

An lot of errors repeated many times about AMR decoding problem

What version of the product are you using? On what operating system?

Please provide any additional information below.

Why did you decide that the AMR frame size is only 32 bytes? :)
Why you do not take frame size from AMR frame header?
It may be from 13 to 32 bytes depending on... I don't know :)
In my situation frame size is 13 bytes

VLC is not showing up any audio blocks being decoded. Checking the AMR stream, 
I am also getting a frame size of 13 bytes. Modifying the code to support this 
frame size still gives me no audio in VLC.  I am using a Samsung Galaxy tab 
10.1 (Android 3.1).

Another thing I've read is that AMR is not supported in VLC without building it 
yourself - can anyone confirm this?

I have not had any time yet to look into the issue even further, but as what I 
think;
I think it is based on the device and how it outputs AMR. Or we can tell more 
on how to output AMR or we need to update VLC with the proper "codecs", I also 
read some posts where VLC was recompiled with different sources for AMR playback
