My use case: I need to build a data stream with scripting/manual
editing. Since I don't want to have to rely on a binary format (which
is not ideal for that use case) I needed a format simple enough to be
written and analysed without special tools, but with a simple text
editor.
I still don't get it. Your description makes me think of something like
EDL, but that doesn't seem to have anything to do with it.
EDL as "Edit Decision List"? No I don't think this is related at
all.
Suppose you want to inject a data stream, you have the data and you
know where to insert it given its PTS. With this muxer you can
handcraft a textual file in the ffprobe_default format and use ffmpeg
to inject the new data stream.
What's a "data stream"?
A stream consisting of generic data, that is a stream with type
AV_MEDIA_TYPE_DATA.
Inject into what?
Interleave the stream with other media streams (audio, video,
etc.). This can be done via remuxing (no need for transcoding).
And why?
Data stream could be used to insert custom information for
post-processing (e.g. they might contain advertising information).
Are you sure this cannot be done from outside of libav*? It really seems
like something which wouldn't actually be very useful for anyone else.
It's also just another hack in for a non-standardised, exclusive format.
Lavf is really not a good fit for this and it should be done outside of
libav*.
