           Summary: gst-plugins-base-0.10.24: theora/enc/dec playback
                    drops buffers/freezes intermittently
    Classification: Desktop
           Product: GStreamer
           Version: 0.10.x
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base
        AssignedTo: gstreamer-bugs at lists.sourceforge.net

Running either of these pipelines leads to choppy playback and frames freezing:

gst-launch -v v4l2src ! video/x-raw-yuv, width=640, height=480,
framerate=30000/1001 ! theoraenc ! theoradec ! queue max-size-buffers=3 !
xvimagesink

This one only freezes at the beginning of playback:

gst-launch -v videotestsrc is-live=true ! video/x-raw-yuv, width=640,
height=480, framerate=30000/1001 ! theoraenc ! theoradec ! queue
max-size-buffers=3 ! xvimagesink

this gets worse as the quality setting is increased. on #gstreamer, thaytan
suggested that theoraenc/dec weren't handling the latency query event properly
as setting sync=false on xvimagesink yields smoother playback.
