[FFmpeg-devel] [PATCH 01/10] lavc/libopenh264enc: Add default qmin/qmax support

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) [1]

[FFmpeg-devel] [PATCH 01/10] lavc/libopenh264enc: Add default qmin/qmax support
