[FFmpeg-user] Preserving both Video and Data Streams in Output file

[Victor Odouard]

Hello all,
I have a mpeg file that I would like to send to a stream, something like:

ffmpeg -i PumaMapping.mpg udp://239.0.0.1:1234

However, this input.mpg file has both a video stream and a data stream, the
latter of which I understand by default ffmpeg does not carry over. I want
to copy both streams to the output file/stream, but I haven't been able to
figure out how.

So I've been trying this:

ffmpeg -i PumaMapping.mpg -map 0 output.mpg

(I've replaced the udp address with an output file to make testing simpler
as I figure out this issue).This is the output I get:

Like DVD, VCD or others, make sure you set the correct buffer size

I also tried this one:

ffmpeg -i PumaMapping.mpg -map 0 -codec copy output_2.mpg

But got a similar error message:

As you can see from both console outputs, the input has two streams, an
H264 video stream and a KLV data stream. How can I preserve both of these
in the output?


Best wishes,
