Control: reassign -1 totem-common Control: severity -1 important
Hey. I think I found the reason for this... I tried with various further debug options: $ /usr/bin/totem-video-thumbnailer -s 256 file:///home/calestyo/test.mp4 foo -v TotemVideoThumbnailer-Message: 06:45:48.757: Initialised libraries, about to create video widget TotemVideoThumbnailer-Message: 06:45:48.763: setting URI file:///home/calestyo/test.mp4 TotemVideoThumbnailer-Message: 06:45:48.763: Video widget created TotemVideoThumbnailer-Message: 06:45:48.763: About to open video file TotemVideoThumbnailer-Message: 06:45:49.000: Checking whether file has cover TotemVideoThumbnailer-Message: 06:45:49.000: Opened video file: 'file:///home/calestyo/test.mp4' TotemVideoThumbnailer-Message: 06:45:49.000: About to seek to 0,333333 TotemVideoThumbnailer-Message: 06:45:49.020: About to get frame for iter 0 (totem-video-thumbnailer:401457): GLib-ERROR **: 06:45:49.023: ../../../glib/gmem.c:112: failed to allocate 1244311 bytes Trace/breakpoint trap $ /usr/bin/totem-video-thumbnailer -v -s 256 file:///home/calestyo/test.mp4 foo TotemVideoThumbnailer-Message: 06:39:48.944: Initialised libraries, about to create video widget TotemVideoThumbnailer-Message: 06:39:48.950: setting URI file:///home/calestyo/test.mp4 TotemVideoThumbnailer-Message: 06:39:48.951: Video widget created TotemVideoThumbnailer-Message: 06:39:48.951: About to open video file TotemVideoThumbnailer-Message: 06:39:49.197: Checking whether file has cover TotemVideoThumbnailer-Message: 06:39:49.197: Opened video file: 'file:///home/calestyo/test.mp4' TotemVideoThumbnailer-Message: 06:39:49.197: About to seek to 0,333333 TotemVideoThumbnailer-Message: 06:39:49.211: About to get frame for iter 0 (totem-video-thumbnailer:400083): GStreamer-WARNING **: 06:39:49.213: failed to create thread: Error creating thread: Resource temporarily unavailable $ /usr/bin/totem-video-thumbnailer -s 256 file:///home/calestyo/test.mp4 foo -v --gst-debug-level= TotemVideoThumbnailer-Message: 06:46:18.672: Initialised libraries, about to create video widget TotemVideoThumbnailer-Message: 06:46:18.679: setting URI file:///home/calestyo/test.mp4 TotemVideoThumbnailer-Message: 06:46:18.679: Video widget created TotemVideoThumbnailer-Message: 06:46:18.679: About to open video file TotemVideoThumbnailer-Message: 06:46:18.917: Checking whether file has cover TotemVideoThumbnailer-Message: 06:46:18.918: Opened video file: 'file:///home/calestyo/test.mp4' TotemVideoThumbnailer-Message: 06:46:18.918: About to seek to 0,333333 TotemVideoThumbnailer-Message: 06:46:18.929: About to get frame for iter 0 ***MEMORY-ERROR***: totem-video-thumbnailer[401516]: GSlice: failed to allocate 4080 bytes (alignment: 4096): Cannot allocate memory Aborted So it seems there is some issue with creating new threads and not enough memory being available for that. With these errors I found: https://blog.frehi.be/2021/06/19/missing-video-thumbnails-in-nautilus-in-debian-bullseye/ Adding a "-l" to the Exec= line in /usr/share/thumbnailers/totem.thumbnailer indeed fixes the issue. I haven't checked now, whether removing libopenblas0-pthread respectively switching to another one, also fixes it, as described in the chat. Since the bug is rather in totem, reassigning it there. Cheers, Chris.
