First of all, your paths to the socket are different: unix:///tmp/ff.socket unix://tmp/ff.socket Secondly, unlike what the ffmpeg documentation says, it looks like you need to add *no* extra slashes, so the correct URI is unix:/tmp/ff.socket (It shouldn't matter in this case, the OS ignores the extra slashes.) Thirdly, with your commands, both commands should give "no such file or directory", because ffmpeg needs to feed (and create) the socket first, before ffplay can access it. Fourthly, to create a socket, you need to add the "-listen 1" option to the ffmpeg command line. Fifthly, if you launch ffmpeg first and try to put it to the background, you need to disable its interaction with the terminal, by adding "-nostdin" (otherwise, it stalls in my attempts). I succeeded with this: $ ffmpeg -nostdin -f lavfi -i testsrc -f mpegts -listen 1 unix:/tmp/ffmpeg.socket & ffplay unix:/tmp/ffmpeg.socket (ffplay doesn't need "-f mpegts" in this scenario.)
