Summary: Transitions with GStreamer Editing Services freezes,
but works OK without transitions
Classification: Platform
Product: GStreamer
Version: 0.10.x
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gst-editing-services
AssignedTo: gstreamer-bugs at lists.freedesktop.org

GNOME version: ---
I'm trying to use gstreamer's GStreamer Editing Services to concatinate 2
videos, and to have a transition between the two.
This command, which just joins 2 segments of the videos together without a
transition, works fine:
ges-launch-0.10 vshort01.mov 0 5 vshort02.mov 5 5 -r -o file:///tmp/foo.mov
Here is the output from it:
$ ges-launch-0.10 vshort01.mov 0 5 vshort02.mov 5 5 -r -o
file:///tmp/foo.mov
save_path: (null)
load_path: (null)
Adding file:///home/rory/vshort01.mov inpoint:0:00:00.000000000
duration:0:00:05.000000000
Adding file:///home/rory/vshort02.mov inpoint:0:00:05.000000000
duration:0:00:05.000000000
Done
If I try to have a short transition between the 2 videos with this command, it
just hangs.
ges-launch-0.10 vshort01.mov 0 5 +transition crossfade 2 vshort02.mov 5 5
-r -o file:///tmp/foo.mov
The output, I get is this:
save_path: (null)
load_path: (null)
Adding file:///home/rory/vshort01.mov inpoint:0:00:00.000000000
duration:0:00:05.000000000
Adding <transition:crossfade> duration 0:00:02.000000000
Adding file:///home/rory/vshort02.mov inpoint:0:00:05.000000000
duration:0:00:05.000000000
And there it hangs. The file /tmp/foo.mov stays at 0 bytes, and there is no CPU
activity.
I am the package ges0.10-tools version 0.10.1-1 on ubuntu 11.04 natty. I have
tried a freshly built version of gst-editing-services from a git clone a while
ago, c2668d058501513b734c8a8013a5e78c817712bb
I tried without the ``-r -o …`` options (i.e. telling ges-launch to display the
video, not render it to a file), and the same problems occur. With the
+transitition, then the window opens (to show the video) showing the first
frame of the first video. But the video doesn't play and there is no CPU usage
etc.
