If I run it as root it runs for a few seconds and responds "Killed"
But; something suspicious is happening because I just went to check the exact output and I got this: $ sudo totem-video-thumbnailer -v sample.mp4 sample.png TotemVideoThumbnailer-Message: 17:38:03.906: Initialised libraries, about to create video widget TotemVideoThumbnailer-Message: 17:38:03.908: setting URI file:///home/aaron/tmp/sample.mp4 TotemVideoThumbnailer-Message: 17:38:03.908: Video widget created TotemVideoThumbnailer-Message: 17:38:03.908: About to open video file OpenBLAS blas_thread_init: pthread_create failed for thread 7 of 16: Resource temporarily unavailable OpenBLAS blas_thread_init: RLIMIT_NPROC 125184 current, 125184 max So I am a liar now.
