Hi, I am using GStreamer 1.0.3-1~ubuntu12.04.1~ppa1 from <a href="https://launchpad.net/~gstreamer-developer">https://launchpad.net/~gstreamer-developer</a> and I noticed frameskips visible in playback of Big Buck Bunny h264 .mov 1080p or 480p video from <a href="http://www.bigbuckbunny.org/">http://www.bigbuckbunny.org/</a> Same problem occurs when I use gst-launch with playbin or a self crafted pipeline. gst-launch-1.0 -v filesrc location=Downloads/big_buck_bunny_1080p_h264.mov ! qtdemux ! avdec_h264 ! xvimagesink gstreamer 0.10 from Ubuntu 12.04 and vlc 2.0.4 do not have this problem on same PC. I have tried two different computers though. Can somebody download the video and try the playback, if he can reproduce the problem? thanks, Juraj
