6539d1da29 videodecoder: Break instead of return if default negotiation on GAP events fails
Otherwise we're going to leak the event.

f268f2be92 videodecoder: Try to invent default caps instead of setting none at all when getting a GAP event before CAPS
Otherwise we would forward the GAP event without ever providing any caps,
which then would make decodebin expose a srcpad without any caps set. That's
confusing for applications and can lead to all kinds of interesting bugs.

Instead do the same as already is done in GstAudioDecoder, and try to invent
caps based on the sinkpad caps and the caps allowed by downstream and the
srcpad template caps.

0c72d0acdf {audio,video}decoder: Forward SEGMENT_DONE events immediately and drain decoders
Otherwise we're going to wait with draining until the next data comes, which
is a bit suboptimal and might take a long time... or maybe never happens.

0d333d8d44 video-converter: add table based matrix8 implementation
Based on patch from Mozzhuhin Andrey <nopscmn at gmail.com>

Add a table based matrix8 multiplication implementation. The algorithm
does not do any clipping so we need to make sure we never call this on
input that might need to be clipped. In general, this algorithm is
2 times faster than the orc optimized one and would be chosen for all
RGB -> YUV conversions and some YUV->YUV and RGB->RGB conversions.

aa645b11f1 video{enc,dec}oder: Don't reset latency all the time and handle max=GST_CLOCK_TIME_NONE correctly
max=NONE means that *this* element has no maximum latency. If upstream had a
maximum latency we must not override it with NONE.

f29b966c79 video-converter: add fast-path scaler for some packed YUV formats
Add fast path scaling for YUY2 and other packed YUV formats. Add a new
method to merge the scalers of the Y and UV components into one scaler.
Add faster horizontal 2tap scaler.

6992da94b0 video-dither: remove check for below zero for unsigned value
CLAMP checks both if value is '< 0' and '> max'. Value will never be a negative
number since it is an unsigned integer. Removing that check and only checking if
it is bigger than max and setting it appropriately.
