On a second thought, I don't think this issue is related to XML, nor
to ffprobe specifically.
If you do:
ffmpeg -i cnet-start.mp4 -c:a copy -c:v copy cnet-start.remux.mp4
the resulting ffprobe output is successfully parsed by xmllint.
ffmpeg remuxes the stream and performs validation on metadata content,
thus stripping all non valid UTF8 characters. So validation should be
performed when extracting the metadata information (demuxer/decoder
level) rather than at the application level.
