The advantages of doing this, beyond increased throughput, would be enforced separation between these components, making the code more local and easier to reason about. This set implements threading for muxers. My tentative plan is to continue with encoders and then filters. The patches still need some polishing, especially the last one. Two FATE tests do not yet pass, this will be fixed in later iterations. Meanwhile, comments on the overall approach are especially welcome. -- Anton Khirnov _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
