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? Thanks Michael <https://codereview.qt-project.org/#change,76764>
