[Bug 1466273] [NEW] gstreamer fails intermittently


You have been subscribed to a public bug:

gstreamer occasionally fails to extract a thumbnail from a video file.
It's clearly a race condition because, almost all of the time, it
succeeds. To reproduce:

Check out the thumbnailer/devel branch at r217 and build it. Then:

cd build/src/vs-thumb

./vs-thumb fd://0 ./x.jpg <../../../tests/media/testvideo.ogg

Point a browser at the generated x.jpg file and check that the image was
extracted correctly.

Now run

while ./vs-thumb fd://0 ./x.jpg <../../../tests/media/testvideo.ogg ; do
:; done

Within maybe a hundred iterations or so, I get:

Error creating thumbnail: ThumbnailExtractor: change_state(): reading
async messages: GStreamer error: negotiation problem.
