Description Michel Lind 2011-06-30 16:47:22 UTC
Description of problem:
The qtdemux element is provided by libgstisomp4.so, but it seems that totem looks for it in libgstqtdemux.so instead. Without symlinking %{_libdir}/gstreamer-0.10/libgstqtdemux.so to point to %{_libdir}/gstreamer-0.10/libgstisomp4.so, totem cannot play back or index files in MOV and MP4 containers.

Version-Release number of selected component (if applicable):
gstreamer-plugins-good-0.10.29-1.fc15.x86_64
totem-3.0.1-2.fc15.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Download http://devimages.apple.com/llvm/videos/LLVM_Assembler_Infrastructure.mov
2. Install rpmfusion-{,non}free-release from rpmfusion.org
   (I don't have a Theora-inside-MP4 file handy at the moment, apologies)
2. Open the download folder in Nautilus
3. Double-click on the file
  
Actual results:
2. -> no thumbnail created
3. -> Totem attempts to search for Quicktime demuxer, but fails


Expected results:
2. -> should generate thumbnail (at least after the file is played back once,
   and the relevant entry in ~/.thumbnails/fail/ removed)
3. -> should play, or (without rpmfusion bits) should not fail on searching for
      qtdemux, which is part of gstreamer-plugins-good

Additional info:
If Gstreamer elements are not needed to be contained within files with matching
names, then this is probably a Totem bug

I can confirm that making the symlink fixes this.

Comment 2 Benjamin Otte 2011-08-05 02:13:34 UTC
Does removing ~/.gstreamer-0.10/registry*.bin fix it, too?

Yes, confirmed. I removed the symlink and ~/.gstreamer-0.10/registry*.bin

Everything works fine.

Comment 4 Michel Lind 2012-02-02 15:23:43 UTC
Closing this bug, then. It'd be ideal if people don't have to muck around with their existing gstreamer registries, but at least it does not affect clean installs.
