good point about CBR... and this would require to get BufferSizeInKB adjusted at the proper place, with InitialDelayInKB On Tue, Nov 28, 2017 at 11:41 PM, Mark Thompson wrote: > On 01/12/17 20:04, Zhong Li wrote: > > Hypothetical Reference Decoding (HRD) model assumes that data

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

Hypothetical Reference Decoding (HRD) model assumes that data flows into a buffer of the fixed size BufferSizeInKB with a constant bitrate. BufferSizeInKB represents the maximum possible size of any compressed frames. Signed-off-by: Zhong Li --- libavcodec/qsvenc.c | 2 +- 1
