I don't know why that would be the case: as far as I can tell that pointer is either valid or NULL; even if we return early from push_frame() or pull_frame(). It may not be related to the issue you've run into but the patch below should help quite a bit if you try running the client more than a minute or two: diff --git a/gtk/channel-display-gst.c b/gtk/channel-display-gst.c index b880ce4..9da078a 100644 --- a/gtk/channel-display-gst.c +++ b/gtk/channel-display-gst.c @@ -221,6 +221,7 @@ static void pull_frame(display_stream *st) // TODO seems like poor memory management if (gst_memory_map(memory, &mem_info, GST_MAP_READ)) { + g_free(st->out_frame); st->out_frame = g_malloc0(mem_info.size); memcpy(st->out_frame, mem_info.data, mem_info.size); I also have a patch that avoids copying the out_frame buffer but given the low CPU usage of the client that should not be an issue. > After I tried with gstreamer using ffmpeg, vp8 doesn't crashed, probably > was problem of gstreamer0.10-plugins-bad but "image freeze" problem remain When does the freeze happen? A short freeze is normal during the transition from the regular transport to the video streaming but that happens in the mjpeg case too. Is the freeze temporary?

In my experience the VP8 encoder saturates a core which is why it is not smooth. When running a test pipeline through gst-laucnh I'm able to solve that by playing with vp8enc's speed and threads parameters but for some reason these have no effect in Spice. gst-launch videotestsrc ! video/x-raw-rgb,width=1024,height=768 ! \ ffmpegcolorspace ! vp8enc speed=2 threads=4 ! \ vp8dec ! ffmpegcolorspace ! fpsdisplaysink -- Francois Gouget <fgouget@xxxxxxxxxxxxxxx> _______________________________________________ Spice-devel mailing list Spice-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/spice-devel
