Don't know why.įor mpv playback the behavior is like with the gstreamer src: But a real movie src worked for both (First ffmpeg cmdline). I had issues both with vlc and ffplay when using the testsrc. You can try this ffmpeg line to create the stream:įfmpeg -r 3 -i -preset ultrafast -an -vcodec libx264 -tune zerolatency -b 900k -f rtp rtp://127.0.0.1:5004įfmpeg -r 3 -f lavfi -i testsrc -s 640x480 -pix_fmt yuv420p -preset ultrafast -an -vcodec libx264 -tune zerolatency -b 900k -f rtp rtp://127.0.0.1:5004 It behaves quite similar although ffplay stream playback is not always flawless anymore. Hey, I tried rebuild this issue with ffmpeg as streaming source. Plays the stream with the given framerate.įfplay -loglevel debug -i -protocol_whitelist rtp,file,udp test.sdp Actual behaviorĭecoding breaks after a few seconds with decoding errors, artefacts and choppy playback Log file Mpv -no-config -log-file=output.txt -demuxer-seekable-cache=no -cache=no test.sdp Expected behavior I tried disabling caching but the behaviour is the same: Mpv -no-config -log-file=output.txt test.sdp Gst-launch-1.0 -v videotestsrc ! video/x-raw,width=640,height=480 ! videorate ! video/x-raw,framerate=3/1 ! x264enc sliced-threads=true tune=zerolatency speed-preset=1 ! rtph264pay ! udpsink host=127.0.0.1 port=5004 Other framerates behave quiet similar (<25 fps).
