Re: [FFmpeg-user] No size progress information available when using tee muxer
Switching the order of the outputs didn't make a difference.
I'm aware of the progress option and I used it already in a non-muxer scenario,
so piping works on Win as well.
However, I can't figure out the right syntax for applying the -progress option
to a single muxer output.
./ffmpeg -i c:/test.mp4 -vcodec libx264 -acodec aac -f tee -map 0:v -map 0:a
"[progress=pipe:1]output.mp4|[f=mpegts]udp://10.0.1.255:1234/"
The colon in 'pipe:1' causes an error as the colon actually separates options.
I wasn't able to find any hint whether this option can be used with the tee
pseudo muxer.
Best regards,
Marcus

It's probably reporting the size of the stream, try reversing that and the
filename ("output.mp4\|[f=mpegts]udp://10.0.1.255:1234"). Also, check out the
-progress option which, at least on *nix, can point to a pipe. (There's also a
stackoverflow article on this.)
