源代码位于“libavcodec/libx264.c”中。正是有了这部分代码,使得FFmpeg可以调用libx264编码H.264视频。 从图中可以看出,libx264对应的AVCodec结构体ff_libx264_encoder中设定编码器初始化函数是X264_init(),编码一帧数据的函数是X264_frame(),编码器关闭函数是X264_close()。 X264_init()调用了如下函数: ...

x264, by default, adaptively decides through a low-resolution lookahead the best number of B-frames to use. It is possible to disable this adaptivity; this is not recommended. Recommended default: 1 0: Very fast, but not recommended. Does not work with pre-scenecut (scenecut must be off ...

Does adding-pix_fmt nv12helped? Yes, it works with this parameter. Or just add "-c:v libx264". But both shouldn't be necessary. So, due to the missing API and it's device dependent, I don't have a idea to solve it automatically. There is an easy method: always use -pix_fmt...
