编码器通常的冲洗⽅法:调用⼀次avcodec_send_frame(NULL)(返回成功),然后不停调⽤ avcodec_receive_packet() 直到其返回AVERROR_EOF,取出所有缓存帧,avcodec_receive_packet() 返回 AVERROR_EOF 这⼀次是没有有效数据的,仅仅获取到⼀ 个结束标志 ...
Hello, My goal is to encode a sequence of raw frames into a h.264 stream. I am using the avcodec_send_frame but it fails with the "Invalid argument" error message: if ((avrc = avcodec.avcodec_send_frame(codecContext, frame)) < 0) { avuti...
