[Libav-user] Encoding audio

[Gonzalo Garramuno]

I am trying to transcode audio from one file to another using my own C++ 
code.
I have the audio divided into frames and want to save each frame of 
audio into a mov file.
After looking at doc/examples/muxing.c, I still have some questions.

When opening the stream, I need to set a c->bit_rate, but I have no idea 
what it means.

Then the stream returns a c->frame_size which is smaller than my audio 
frames.
I am currently reseting c->frame_size = frame->nb_samples, but not sure 
if this is correct.
