Sorry I was imprecise. The issue is that ff_codec_close() is called during
"free_and_end", which releases a bunch of fields on the AVCodecConte
When encoding a DASH stream in live ("dynamic") mode without timeline,
the field "availabilityStartTime" is set to the system time. The new
options allows the libavformat user to pass a specific time to be used
instead of the system time.

Hi
Does rtspenc actually support AVFMT_GLOBALHEADER? It is specified in the
FFOutputFormat flags but I can't see anywhere in the code where
extradata is referenced like it is in other output formats which support
that flag.
