* dca: consider a stream with XXCh/X96 in ExSS as DTS-HD HRAAnssi Hannula2011-01-21
| | | | | | | | | | | DTS-HD HRA streams do not always have an XBR extension in the extension substream. Instead they can have only XXCh and X96 extensions in there and still be considered DTS-HD HRA. This is also confirmed with Onkyo TX-SR607 receiver which recognizes such a stream as HiRes Audio.

| | | | | | | | The original functions did not work correctly for edge pixels, e.g. when CODEC_FLAG_EMU_EDGE is set, leading to corrupt output in e.g. VLC. Based on a patch by Daniel Kang <daniel d kang gmail com>. Signed-off-by: Ronald S. Bultje <rsbultje gmail com>

* H.264: Partially inline CABAC residual decodingJason Garrett-Glaser2011-01-15
| | | | | | | | | | Improves CABAC performance about ~1.2%. Trick originates from x264 and has also been used in ffvp8. It's useful because coded block flags are usually zero, so it helps to have the early termination inlined into the main function.

* Second hunk from secrity fix from google.Frank Barchard2011-01-15
| | | | | | | | | | | | | The hunk is not fully understood but it just makes a check tighter so its safer for us to apply until it is fully understood. Might fix issue 2550 (and Chrome issue 68115 and unknown CERT issues).
