Remove the pdiff_lut_scale in nlmeans and increase weight_lut table size from 2^9 to 500000, this change will avoid using pdiff_lut_scale in nlmeans_slice() for weight_lut table search, improving the performance by about 12%. (in 1080P size picture case). Use the profiling command like: perf stat -a -d -r 5 ./ffmpeg -i input -an -vf nlmeans=s=30 -vframes 10 \ -f null /dev/null without this change: when s=1.0(default value) 63s s=30.0 72s after this change: s=1.0(default value) 56s s=30.0 63s Reviewed-by:Carl Eugen Hoyos <ceffmpeg@gmail.com> Signed-off-by:

When making a new P-frame when B-frames are present the previous P-frame is normally in the DPB because it will be referred to by subsequent B-frames. However, this is not true if there are no B-frames, or in edge cases where a GOP ends with two P-frames. Fix this by adding the direct ref pics to the RPS explicitly. Fixes #7699.

The specification requires the demuxer to only read the data atom up to its given size, this is necessary as atoms are allowed at the end of the file. This patch duplicates the behaviour of the QuickTime player.

The VP3/4/5/6 reference decoders all use three IDCT versions: one for the DC-only case, another for blocks with more than 10 coefficients, and an optimised one for blocks with up to 10 AC coefficents. VP6 relies on the sparse 10 coefficient version, and without it, IDCT drift occurs. Fixes: https://trac.ffmpeg.org/ticket/1282Signed-off-by:
