mpv had refcounted frames before libav*, so we were not using libavutil's facilities. Change this and drop our own code. Since AVFrames are not actually refcounted, and only the image data they reference, the semantics change a bit. This affects mainly mp_image_pool, which was operating on whole images instead of buffers. While we could work on AVBufferRefs instead (and use AVBufferPool), this doesn't work for use with hardware decoding, which doesn't map cleanly to FFmpeg's reference counting. But it worked out. One weird consequence is that we still need our custom image data allocation function (for normal image data), because AVFrame's uses multiple buffers. There also seems to be a timing-dependent problem with vaapi (the pool appears to be "leaking" surfaces). I don't know if this is a new problem, or whether the code changes just happened to cause it more often. Raising the number of reserved surfaces seemed to fix it, but since it appears to be timing dependent, and I couldn't find anything wrong with the code, I'm just going to assume it's not a new bug. |
