Here is today's contribution to the global pool. This data is a little hard to find.
As far as I know there are two FLOSS ways to make video thumbnails. Using mencoder:
mencoder /tmp/tmpMPbaKN/35dffc402a4b439978e6e05170d401c76b3c8cf0 -ovc lavc -nosound -lavcopts vcodec=mjpeg:vqscale=2 vf scale=100 -of lavf -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames:format=image2pipe -ss 1.0 -frames 1 -o out.jpg
...and using ffmpeg:
ffmpeg -i /tmp/tmpMPbaKN/35dffc402a4b439978e6e05170d401c76b3c8cf0 -f mjpeg -t 0.01 -y out.jpg
Neither one works particularly well with incomplete video files.
