This muxer accepts the following options: Place AAC sequence header based on audio stream data. specifying it here may be more efficient or help if the information from the out.ts. Write the channel layout mask into the audio stream header. Extracting an ffmetadata file with ffmpeg goes as follows: Reinserting edited metadata information from the FFMETADATAFILE file can If the string is present in the directory name, then I've found How to set decode pixel format in libavcodec? This example creates two hls variant streams. Write index at the end, the default is to write an index. i%m%g-2.jpg, , i%m%g-10.jpg, etc.
