81471099d2 videodecoder: error out if no frames are decoded before eos
Raise an error in case no frames are decoded before EOS and we
have input, meaning that data was received but it was somehow invalid.

0765962fbc videodecoder: allow using -1 for infinite tolerated errors
Allows using -1 to make videodecoder never post an error message
after decoding errors.

cd52ff313e videodecoder: try to negotiate the buffer pool even though there is no o/p format
We could have allocation query before caps event and even without caps inside
the query. In such cases , the downstream can return a bufferpool object with
out actually configuring it. This feature is helpful to negotiate the bufferpool
with out knowing the output video format. For eg: some hardware accelerated
decoders can interpret the o/p video format only after it finishes the decoding
of one buffer at least.

35ee4b056b videodecoder/videoencoder: Mark pads as requiring reconfiguration again if negotiation fails
Otherwise we might end up in non-optimal configuration, especially
when a flush happened during reconfiguration.

d1cf4b2b9a videocoder: Don't push out identical caps
This avoids triggering plenty of extra code/methods/overhead downstream when
we can just quickly check whenever we want to set caps whether they are
identical or not

695675ab7e videodecoder: Don't reset decoder on segment events
Either there was a flush before that resets everything anyway,
or resetting would make us lose information we might need if
it's just a segment update.

612a2cf9d0 videodecoder: Refactor GstVideoDecoder::reset() handling a bit

0c2c909497 video: Always provide a buffer in gst_video_(enc|dec)oder_allocate_output_buffer()
We have no way of tell the caller of the exact error (e.g. if we're flushing),
so will have to wait until the caller uses API that returns a GstFlowReturn,
for example when pushing this buffer.

c3651a7905 videodecoder: always send the new buffer to parse functions
When we get a new buffer, always call the parse function, even if it is a 0
sized buffer. For theora we need to also decode 0 sized buffers.
Ideally we would like to make theoradec be packetized but that fails currently
because of oggdemux and because of the assumptions that the base class makes.

31312d586e videodecoder: Don't blindly assign DTS to PTS
DTS and PTS usually have a non-zero offset between them in MPEG-TS,
so assigning DTS to PTS is almost always wrong.  The other, newer
timestamp recovery code does it correctly if we leave it as invalid.

ceb6585d26 videodecoder: warn if frame list gets long
Decoders that get unparsed input are internally leaking nearly
every incoming buffer.  This checks that case.

706498cb6e videodecoder: finetune missing timestamp estimating
Monitor for reordered output timestamps, and then avoid oldest DTS
as PTS approach, and try for an oldest PTS as out PTS approach,
if at least all valid PTS available.

Avoids bogus estimating upon sparse available input PTS, and tries
to handle all-keyframe input, or input PTS which are actually DTS.
