Does anybody have an idea? If you are not using -re you process the streams as fast as possible. You are filling your local network buffer faster than your consumer can process it. Either enlarge the network buffers or throttle it using -re. (I prefer having the kernel do the work using larger network buffers than have a possibly brittle and surely bufferbloated solution that require a worker thread filling a buffer queue as fast as possible and then have the reader cope with the additional complexity) lu _______________________________________________ libav-api mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-api
