This patch enables variable bit-rate for vaapi encoding. According to
va.h,
target bit-rate equals to maximum bit-rate multiplies by
target_percentage.
Signed-off-by: Boyuan Zhang <boyuan.zh...@amd.com>
That was astonishing simple to fix :)
Patch is Reviewed-by: Christian König <christian.koe...@amd.com>.
Leo do you want to push it or should I take care of this?
I will take care of it.
