Edward Hervey c4d987b6d3 codecparsers: Variant of _identify_nalu without checks
This is useful for cases where the caller *knows* that the provided
input contains a whole NALU and can therefore avoid:
* the expensive checks for the next start code (which won't be present)
* delaying the input parsing (since we would need the next incoming NALU
  in order for the parsing code to detect the next start code)

Mark Nauwelaerts ef24518b60 h264parse: optimize slice nal processing
Only minimal slice info is needed here to determine real frame start,
so no need to parse extensively.

Fixes #665418.

Alexey Fisher 2099a39459 mpegpsdemux: recalculate adjust if difference is negative
One of my dvds jump on some position and miss about 1 minute of stream.
The reason was mpeg timestamps. On some position scr difference is negative.
It produced negative timestamps. Since it was converted to unsigned value,
gstreamer timestamps was invalid. Instead of increasing mpeg ts,
they was decreasing till it started to be positive.

The jump in timestamps caused mpeg2dec to skip frames to make QoS happy.

This patch just make diff unsigned to avoid negative values.

Vincent Penquerc'h 9eb79984a8 kate: support for rendering on several YUV formats
This speeds up rendering a fair bit by not requiring colorspace
conversion, whether there is anything to overlay or not.

The blending code was nicked from textoverlay. I would think
this might be a helpful thing to put in, say, libgstvideo at
some point.

Vincent Penquerc'h 4735a7554b mpeg4videoparse: fix number of bytes read for fixed time increment
The spec I found says "16 bits".
The existing code used log2(somevalue)+1.
ffmpeg uses log2(somevalue-1)+1.
The code now uses log2(somevalue-1)+1, and this makes it work with
some sample video without breaking another sample.
Now, I'm far from certain I've got the right spec, I found it by
searching the internet, so...
