Bad playback of RTSP streams on imx6 platform [Qt5.3] (Michael)э ---------------------------------------------------------------------- Message: 1 Date: Sat, 19 Apr 2014 10:02:41 +0200 From: Michael <auslands...@gmx.de> Subject: [Interest] Bad playback of RTSP streams on imx6 platform [Qt5.3] To: "interest@qt-project.org" <interest@qt-project.org> Message-ID: <53522da1.9060...@gmx.de> Content-Type: text/plain; charset="iso-8859-15" Hi I'm using QT5.3 from git on an imx6 board. Multimedia playback performance has greatly improved with this commit (https://codereview.qt-project.org/#change,76764). Performance of video playback is typically pretty much on par with a native gstreamer pipe. However, this does not apply to RTSP streams. While the following gstreamer pipe plays (nearly) perfectly on the commandline: gst-launch rtspsrc location=rtsp://axis-cam1/axis-media/media.amp ! decodebin2 ! mfw_v4lsink sync=false Playing the same with Qt5 qml MediaPlayer drops lots of frames (about 90% or more), although CPU usage is very low < 10%. Warning: "A lot of buffers are being dropped." Warning: "A lot of buffers are being dropped." Warning: "A lot of buffers are being dropped." Also, playback takes up to 5 seconds to start, whereas the cmdline nearly start immediately. I can get a similar, although not as bad, experience when using sync=true on the mfw_v4lsink element. Not sure though, if this is relevant. Anybody knows how best to debug or even to solve this problem?
