I would like to ask what skills you need to learn to learn ffmpeg first


first of all, your encoder is wrong. X264 corresponds to AV_CODEC_ID_H264.

second, ffmpeg has its own AV_PIX_FMT_NV21.

third, the first frame should be set to keyframe, and then give another keyframe every other GOP frame.

Finally, you might as well start with the simplest JPEG (AV_CODEC_ID_MJPEG) coding, learn the basics of ffmpeg, and then make a video, which is actually dealing with a lot of pictures linked together.
