I gave michi's branch and test videos a try. For the six videos being thumbnailed in parallel, I see two successful thumbnails, two instances that look like they died due to invalid memory allocations:
(vs-thumb:15299): GLib-ERROR **: /build/buildd/glib2.0-2.45.1/./glib/gmem.c:357: overflow allocating 4294967274*8 bytes (vs-thumb:15298): GLib-ERROR **: /build/buildd/glib2.0-2.45.1/./glib/gmem.c:357: overflow allocating 4294967274*8 bytes And two that have stuck around eating a little more than one CPU each. I was able to kill -9 them though. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gstreamer1.0 in Ubuntu. https://bugs.launchpad.net/bugs/1466273 Title: gstreamer fails intermittently Status in Thumbnail generator for all kinds of files: New Status in gstreamer package in Ubuntu: New Status in gstreamer1.0 package in Ubuntu: New Bug description: 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.
