硬解码
IJKVideoToolBoxSync.h
- videotoolbox_sync_decode_frame // 不断循环取AVPacket
- decode_video->decode_video_internal //取到AVPacket后执行硬解码
- VTDecoderCallback
- SortQueuePush ->Ijk_VideoToolBox_Opaque->m_sort_queue(sort_queue)//用于每次获取大pts的帧
- QueuePicture->queue_picture->frame_queue_peek_writable(&is->pictq)->frame_queue_push(&is->pictq); //加入渲染queue
