I can't reproduce this with any of the audio streams I have available. Perhaps you need to provide a sample file. (I don't know the source enough yet to be able to understand whether this should be happening or not.) > Here is the command and the output when it produces an undesirable file > size: > Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, > fltp, 95 kb/s (default) [...] > For reference, here is the output when an rtmp stream is used as an input: > Stream #0:1: Audio: mp3, 22050 Hz, mono, s16p, 49 kb/s I need to point out that mono and stereo inputs will result in differing sample sizes. If you want to keep the two comparable, you need to add "-ac 1" to the command lines. Do you happen to be using an input file where the channel layout changes during time? That would be a cause. I'm not sure the mp4 container allows that though (MPEG-TS does).
