Sorry, that is not what I meant (although it may or may not be an issue). I meant that for the same ffmpeg command line and the same input file, I believe that with your patch, the output file (suddenly) has one track more than before (because the data codec is now listed in AVOutputFormat, the ffmpeg cli will try to add this track if the input file provides such a codec). Maybe this is wrong because the data codec does not produce a new track if it is passed to the muxer? Iirc, my question was equivalent to: Can you just remove the additional ".data_codec=" lines or is it intended that they are now default codecs? (Or am I simply wrong and they either do not lead to a new track and / or ffmpeg simply ignores them because it only fills video, audio and subtitle tracks?)
