Hi,

I've tried many combinations, but it doesn't seem ffmpeg supports writing raw AAC. Is there actually something like this or should it be encapsulated in ADTS or something alike?! It doesn't seem ffmpeg does support this either. Is this true, is there a workaround? My final goal is to have two separate streams that can be muxed by MP4Box (gpac) into proper mp4. I already tried to make ffmpeg export mp4 and then mangle it using gpac, but gpac segfaults on the video stream no matter what I do, so I guess something is wrong, and for the time being I assume it's in the mp4 container. Does anyone have experience in this area? My utter final goal is to fix the ffmpeg mp4 muxer, but that may still take some time :-( Maybe I could make ffmpeg use the gpac muxer some way, it seems they have the muxer in a lib, but I guess that would not be preferred by the ffmpeg devs. Does the fact, that the mp4 muxer still is broken and nobody complains, mean that everybody is actually using avi?!

I use it oftenly. Im very interested in mp4 muxer work. What did you find not working ?
