Support MPEG2 Layer2

[amirvalhalla]

Hi,

I've been working with your awesome package, and it works well for most of audio/video codecs. However, I've encountered a challenge as I'm currently looking to decode MPEG2 Layer2, which unfortunately the package doesn't support. I'm curious if there's a specific reason for not supporting MPEG2 Layer2 and if there are any plans to include support for it in the future.

Thank you!

Hello, there is no particular reason for not supporting MPEG-2 layer 2 (by the way, this limitation lies in mediacommon and not in gortsplib, which is already fit for handling any MPEG combination), other than the fact that this feature wasn't requested until now. Just provide a sample MPEG-2 layer 2 file or a FFmpeg / GStreamer command that allows to generate it and i'll add support for it.

Okay, I'll provide the 'command' or a sample 'MPEG-2 layer2' file and come back to you.

@aler9
you can use below command to simulate MPEG2-Layer2.

ffmpeg -i noise.wav -c:a mp2 -b:a 192k output.mp2
