Bug#819266: ffmpeg: rtmp is broken

[Ralf Jung]

Hi,

Please keep me in Cc in the mails, bugs.d.o doesn't otherwise seem to
deliver them to me.

As a library, yes -- as I said, mpv and vlc. The error message was even
prefixed with [ffmpeg]. I'd say starting by reporting against ffmpeg is
a good first guess given these hints; of course it may well turn out
that the actual problem lies elsewhere.

I wouldn't know how else to test this with ffmpeg; I did not know you
could use the ffmpeg command to "convert" RTMP streams.

This does not work here with the Debian packages:

I did "aptitude reinstall '?any-version(?source-package(^ffmpeg) ~i)'"
so I am pretty sure I got the Debian version of all ffmpeg packages again.

Kind regards,
