[Libav-user] Writing Audio AVPacket without resampling

[sebastian.wichmann at karlsruhe-it-solutions.com]

Hello,

I'm very new to this subject, so I'm not sure what you mean.
At the moment I can't even tell you the codec of the read AVPacket. 
I can tell you that I'm trying to resample it to AV_SAMPLE_FMT_FLTP.

The problem that I'm currently facing is that I cant get the codec from an AVPacket. Is there anyway to gain access to this?

Best regards
Sebastian Wichman

Did you try to write pcm_s16be?
