[Libav-user] Conversion from mp3 to aac/mp4 container problem

[Taha Ansari]

I have another observation:

When transcoding from mp4 to mp4 (using my code), I see
codec_ctx_audio->frame_size is equal to 1024 (that is decoder codec
context), and encoder codec context's frame_size is allocated the same
(1024).

Whereas, while converting from mp3 to mp4, codec_ctx_audio->frame_size is
1152, and encoder codec context frame_size is 1024.

I am thinking these could be related, if I figure out magic going on here,
I might be able to proceed better....?
