In function ff_mpeg_ref_picture(), it returns 0 on the error path that
the return value of av_buffer_ref() is NULL. 0 indicates success, which
seems to deviate from the fact. Set ret to AVERROR(ENOMEM) to propagate

Sometimes end_pts is getting initialized to audio stream's
first pts, while the duration is calculated based on video stream's pts.
In this patch the end_pts is initialized with the correct stream's first pts.

The function avformat_alloc_context() will return a NULL pointer on
failure. However, in function read_ffserver_streams(), its return value
is not validated and the subsequent dereference may result in a bad
memory access bug. Check its return value against NULL and avoid
potential NULL dereference.

Writes one set of field framing information for progressive streams and
two sets for interlaced streams. Fixes ticket #6383.

Unfortunately the OpenDML v1.02 document is not very specific on what
value to use for start_line when frame data is not coming from a
capturing device, so this is just using 0/1 depending on the field order
as a best-effort guess.

I'm told my prefix work-around wasn't enough to make it compile,
although I'm not sure why; I did some basic testing and that
approach appeared to work, but I'm not in a position to do a
full compile on CentOS 6 so I can't be sure of anything.

I have had it confirmed that the additional change to not use
named initialisers is enough to make it compile, so let's
throw that into the mix too.

Ancient versions of gcc (pre 4.6) can't directly initialise
members of anonymous inner unions/structs by name.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=10676

Unfortunately, RHEL 6 shipped with one of these ancient
versions and so we're stuck with it until approximately the
heat death of the universe.

Putting explicit braces into the initialisation is possibly a
work-around but the behaviour there was never fully understood
before direct initialisation was made to work.

So, this may or may not work.
