Previously, prompeg_write() would only report to caller that bytes we
written when a FEC packet was actually created.  Not all RTP packets are
expected to generate a FEC packet however, so this behavior was causing
avio to retry writing the RTP packet, eventually forcing the FEC state
machine to send a FEC packet erroneously (and so breaking out of the
retry loop).

This was resulting in incorrect FEC data being generated, and far too
many FEC packets to be sent (~100% FEC overhead).

It is a constant known at codec init, so set it in
ff_frame_thread_init(). Also, only set it for video, since the meaning
of this field is not well-defined for audio with frame threading.

contexts after 1f4cf92c.

This causes regressions in end to end timestamps with mp3s and ffmpeg.
The revert is to avoid this regression in the 4.3 release

See: [FFmpeg-devel] [PATCH] Don't adjust start time for MP3 files; packets are not adjusted.

This reverts commit 460132c9.

This makes got_output consistent with the code in slice_end() which sets the output

They are no longer necessary there and have nothing to do with parameter
sets, so do not belong in hevc_ps.h.

This effectively reverts 4aaace8b.

It is only used to store a few local variables within one function,
which is better accomplished by just declaring them on stack explicitly.

Inside a function, the second ; in a double ;; is a null statement, but
outside of functions a double ;; is simply invalid C that compilers
happen to accept. v4l2_m2m_enc.c contained several ;; as a result of
macro-expansion. So change the underlying macro so that it doesn't
happen any longer.

This fixes warnings when compiling with -pedantic: "ISO C does not allow
extra ‘;’ outside of a function".
