Can't get ffmpeg to generate an MP4 file on iOS -


i'm having serious problems trying ios app create mp4 file rtsp stream using ffmpeg.

i can open stream, decode it, show video on screen , play live audio without issues. problems arise when try output av stream file.

if ask ffmpeg create mp4 file, fails, informing me audio codec in stream incompatible mp4 files. if attempt transcode audio acc, ffmpeg lets me continue, during file output multiple "aac bitstream error" messages, , recording silent.

i tried having ffmpeg create mov (quicktime) file instead of mp4. if that, seems work: mov file plays audio. being done, tried transcode mov file mp4 using avassetexportsession. doesn't work: reports decode failed.

i'm not sure try next.
