Bug#852160: gstreamer1.0-vaapi: presence breaks totem-video-thumbnailer

[Christoph Anton Mitterer]

Package: gstreamer1.0-vaapi
Severity: important


Hi.

This problem exists since quite a while now, as soon as gstreamer1.0-vaapi
is installed totem-video-thumbnailer fails to create thumbnails for many
formats (I've noticed e.g. WMV, realmead, some mpeg container formats).


For example with the package being installed:

$ totem-video-thumbnailer --verbose video.wmv foo.jpg
TotemVideoThumbnailer-Message: Initialised libraries, about to create video widget
TotemVideoThumbnailer-Message: setting URI file:///tmp/video.wmv
TotemVideoThumbnailer-Message: Video widget created

calestyo at heisenberg:~/data/__todo/.HSA/deletable$ totem-video-thumbnailer --verbose video.wmv foo.jpg --gst-debug
couldn't parse command-line options: Missing argument for --gst-debug




And without it being installed:

$ totem-video-thumbnailer --verbose video.wmv foo.jpg
TotemVideoThumbnailer-Message: Initialised libraries, about to create video widget
TotemVideoThumbnailer-Message: setting URI file:///tmp/video.wmv
TotemVideoThumbnailer-Message: Video widget created
TotemVideoThumbnailer-Message: About to open video file
TotemVideoThumbnailer-Message: Checking whether file has cover
TotemVideoThumbnailer-Message: Opened video file: 'video.wmv'
TotemVideoThumbnailer-Message: About to seek to 0,333333
TotemVideoThumbnailer-Message: About to get frame for iter 0
TotemVideoThumbnailer-Message: Frame for iter 0 is interesting
TotemVideoThumbnailer-Message: Saving captured screenshot



This affects of course any piece of software that uses totem-video-thumbnailer
for creating thumbails (e.g. nautilus).


Cheers,
Chris.
