* avcodec/mpeg4_unpack_bframes_bsf: Use avpriv_find_start_codeAndreas Rheinhardt2019-02-04
| | | | | | | | | | | instead of an ad-hoc function to search for start codes in order to remove code duplication and to improve performance. Improved performance of finding startcodes from 52606 decicycles to 9543 decicycles based upon 262144 runs for a 1 Mb/s MPEG4 video.

* lavfi/nlmeans: improve the performanceJun Zhao2019-02-01
| | | | | | | | | | | | | | | | | | | | | | | | 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: Jun Zhao <mypopydev@gmail.com> Signed-off-by: Clément Bœsch <u@pkh.me>

* vaapi_encode_h265: Ensure that ref pics are always in the RPSMark Thompson2019-01-27
| | | | | | | | | | | | 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.
