Multiplexing data stream and video stream

[Palak92]

Is there any way to mux data stream and video stream in FFMPEG?

This is more of an ffmpeg question, but yeah, you just do two inputs like ffmpeg -i audio -i video output_here see also https://trac.ffmpeg.org/wiki/Map if you want to pick out particular inputs to an output

I can mux audio and video stream but not data stream and video stream. Here's console command ffmpeg -i out.mp4 -i data.txt -map 0:0 -map 1:0 -c:v copy -c:d copy outputMerged.mp4

Output:

  Metadata:
    major_brand     : isom
    minor_version   : 512
    compatible_brands: isomiso2avc1mp41

File 'outputMerged.mp4' already exists. Overwrite ? [y/N] y
[mp4 @ 00000000030501a0] Could not find tag for codec ansi in stream #1, codec not currently supported in container
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument

What are supporeted codecs for data stream?

OK yeah I know nothing about data streams, maybe ask on ffmpeg-user mailing list, good luck!
