Hello! Some questions: 1a. I would like to know where I can find documentation about ffmpeg reference counting. Is this the starting point or there are other resources? "http://www.ffmpeg.org/doxygen/2.0/group__lavu__buffer.html".
1b. Is this the official url for examples code? "http://www.ffmpeg.org/doxygen/2.0/examples.html" 2. I would like to know if the following code is safe if result==TRUE and r ==1. There are additional questions on the code comments. AVPacket pkt; ... pkt.buf = NULL; // no ref count. Does it matter? // pkt was properly initialized and data filed != null. ... BOOL result = (av_write_frame(oc, &pkt) == 0); if (result) { int r = av_write_frame(oc, NULL); // flush if (r == 1) { av_free_packet(&pkt); // now pkt can be safely reused? <====== } } 3. I would like to know if the following code is safe if result==TRUE. There are additional questions on the code comments. AVPacket pkt; ... // now pkt is ref counted and properly filled. ... BOOL result = (av_interleaved_write_frame(oc, &pkt) == 0); if (result) { // From doc: "...Libavformat takes ownership of this reference..." // so... // I dont need to free packet, muxer will do that at right time. Correct? // so now pkt can be safely reused? <====== } 4. From doc: "...If the packets are already correctly interleaved, the application should call av_write_frame() instead as it is slightly faster...". 4a. If av_interleaved_write_frame is fed with an already interleaved packet list, is this performance difference still notable? 4b. if av_interleaved_write_frame puts the packet in a private list, the function call should take less time compared to av_write_frame, correct? The muxer I'm using is ASF. thanks, MB
