[libav-devel] [PATCH V2] lavc/qsvenc: set HRD buffer size

2017-12-01 Thread Zhong Li
Hypothetical Reference Decoding (HRD) model assumes that data flows into a buffer of the fixed size BufferSizeInKB with a constant bitrate. Smaller BufferSizeInKB means smaller frame size variations, but more difficult to maintain HRD. Signed-off-by: Zhong Li --- libavcodec/qsvenc.c | 1 + 1 fil
