1d16a1cf99 Rename h264_idct_sse2.asm to h264_idct.asm; move inline IDCT asm from 
h264dsp_mmx.c to h264_idct.asm (as yasm code). Because the loops are now
coded in asm instead of C, this is (depending on the function) up to 50%
faster for cases where gcc didn't do a great job at looping.

Since h264_idct_add8() is now faster than the manual loop setup in h264.c,
in-asm idct calling can now be enabled for chroma as well (see r16207). For
MMX, this is 5% faster. For SSE2 (which isn't done for chroma if h264.c does
the looping), this makes it up to 50% faster. Speed gain overall is ~0.5-1.0%.

4693b031a3 Move H264 dsputil functions into their own struct 
This moves the H264-specific functions from DSPContext to the new
H264DSPContext.  The code is made conditional on CONFIG_H264DSP
which is set by the codecs requiring it.

The qpel and chroma MC functions are not moved as these are used by
non-h264 code.

2ce1c2e063 Always reset slice_table. 
Previously, the area of a lost slice would be left at the slice number of the previous
frame which could occasionally match the number of the next slice and thus a non existing
slice could have been used for prediction leading to additional decoding errors in otherwise
undamaged slices.

7a00bbad21 Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an

flag, which appears necessary to playback corePNG P-frames.

79db7ac6ef Fix memory leak in h264 decoder. allocated_edge_emu_buffer was being allocated 
in both mpegvideo and h264 decoder. Fixed by allowing all (master and duplicate)
contexts to fully initialize in MPV_frame_start and copying these into
H264Contexts.

picture buffer overflow and abort.

ad1ea1f155 When dst_length == 0 bit_length has to be 0, too, but the current code still 
calls decode_rbsp_trailing() and therefore bit_length might get negative.
Although the remaining code is able to handle a negative bit_length, avoid
the calculation at all by setting bit_length to 0 for dst_length == 0.

6ac9696e77 Remove a NAL unit's trailing zero bytes even when dst_length is 1. 
Consider the following byte sequence

    00 00 01 0a 00 00 00 01 09 ...
               ^  ^
               A  B

decode_nal() determines dst_length to be 1 (i. e. the byte between label
A and B above). However, this byte is a trailing zero byte as the spec
says the the current NAL unit is terminated by a byte sequence 00 00 00.

The current code used a loop to decrement dst_length accordingly. But the
loop doesn't start as the loop condition checks for dst_length > 1, which
should read dst_length > 0.

ff82e429cb scenario: A properly coded frame is followed by an end of sequence NAL unit, 
i.e. the four bytes 00 00 01 0a.
When decode_nal() decodes the end of sequence NAL unit, it returns with
dst_length == 0. The original code leads to a return -1 which discards
the current properly decoded frame.

subject: [Ffmpeg-devel] h264, protection against corrupted data

this also fixes a possible security issue (the sps and pps ids where not checked,
then used as index into an array of sps/pps structs which was then filled with data from the bitstream)

ebd624b662 optimize sign decoding code in decode_residual() 
x86 is 4% faster on P3
C sign stuff + x86 code for everything else is also faster then before (sorry forgot to test pure C)
... and if i replace the second occurance of the sign decoding in decode_residual by the asm too then everything gets slower iam starting to think that it might be best to write the whole function in asm, playing this avoid random deoptimizations game with gcc is not fun at all
