[FFmpeg-user] av_interleaved_write_frame(): Broken pipe

[tasos]

Hello.
I know that this command has issues but this is exactly what was
running when the problem occured(this is how someone else runs it
and h i have to find the problem :( ).
My thought was that a specific method has a problem that's why
i told you about the devs list.
I'm not in a hurry, i just want like to know if this is the right place
to ask this question :)

I can have a log of this one and let you know!
Thanks again!
