[FFmpeg-devel] [PATCH] Improved the performance of 1 decode + N filter graphs and adaptive bitrate.

With new option "-abr_pipeline" It enabled multiple filter graph concurrency, which bring obvious improvement in some 1:N scenarios by CPU and GPU acceleration Below are some test cases and comparison as reference. (Hardware platform: Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz) (Software: Intel iHD d

[FFmpeg-devel] [PATCH] avcodec/prores_ks reduce twice fdct calls

fdct done twice for each block. first time during quant calculation, second during slice encoding. so if we pre-save dct coefficients no need to do fdct second time. disadvantages: requires more memory advantages: improves performance ~4-5% --- libavcodec/proresenc_kostya.c | 74
