The video codec used is mpeg4 and I would like to use the PCM_16LE for t

Answer 1

As you can see in pcm_encode_init function in pcm.c

All pcm encoders have frame_size = 0;. Why?

Because in all PCM formats 'De facto' no such thing like frame, there is no compression by nature of PCM.

So you should decide by your own how many samples you wanna to store in buffer
