This is generally not possible with FFmpeg: You are expected to know what you try to put into a container. This is further complicated by several facts (issues) about FFmpeg: General purpose containers (like avi) accept everything. Other containers like mpeg-ts and mpeg-ps accept everything although a very small number of codecs is actually supported. Other containers do support certain codecs but FFmpeg does not support writing them. > I tested this approach: > Prepare writing to memory buffer and execute just avformat_write_header and > av_write_trailer (no actual packets). > If neither function returns an error, assume the formats are compatible. > > This seems to solve great part of the problem, but there are exceptions: > pcm in mp4 is successful (no errors reported) This surprises me, the error that is shown here in my tests is often reported by users.
