tee muxing problem when -vcodec copy

[arsen]

Summary of the bug:
Tacking input stream, then sending without video transcoding to 1 or 2 servers. As result ffmpeg cannot start.
In case if using trans-coding it works well

How to reproduce:

Tee mux seems to be a bit buggy to me as well ( ​https://trac.ffmpeg.org/ticket/4096 )

[arsen]

guys, when we can expect this issue fixing ?

[Carl Eugen Hoyos]

Is this issue still reproducible? Is network input required to reproduce?
