[FFmpeg-devel] [PATCH 1/7] lavc/libopenh264enc: Add default qmin/qmax support

2020-03-31 Thread Linjie Fu
Set default QP range to (1, 51) instead of (2, 32). QP = 0 is not well supported currently in libopenh264. If iMaxQp/iMinQp equals 0, the QP range would be changed unexpectedly inside libopenh264 with a warning: Warning:Change QP Range from(0,51) to (12,42) Signed-off-by: Linjie Fu --- [1]
