Summary of the bug:
I try to find a solution to update metadata in a generated HLS live audio
stream dynamicaly.
I came up with this idea:
mkfifo /tmp/metadata.fifo
ffmpeg -i http://some.icecast.url:8000/broadcast -f ffmetadata -i
/tmp/metadata.fifo -map_metadata 1 ...
echo "artist=Test" >> /tmp/metadata.fifo
but that doesn't work out beecho "artist=bla2fsa" >>
/tmp/metadata.fifocause ffmpeg doesn't seem to read the names pipe after
new data arrived there. Otherwise it would be a great solution to allow
dynamic metadata updates. Do you see a way to allow ffmpeg to read from
the fifo continouisly?
How to reproduce:
{{{
% ffmpeg -i input ... output

built with gcc 12 (Debian 12.2.0-14)
