  • FFMpeg generates still video

    19 juillet 2013, par Jason Muchow

    I'm doing a simple test of ffmpeg. I'd like to use it for thumbnail generation / video grabbing for a website I'm developing. I'm currently using VLC to grab a single frame and then generate a thumbnail, but it's rather slow and a bit cumbersome.

    The problem is that the video I'm using (from my own pc) is generated by security camera software and it has an odd video format. When I open it (.bvr) in VLC, it plays very, very fast. A 10 second video goes by in about 2.5 seconds. Additionally, using a simple convert with ffmpeg "ffmpeg -i test.bvr output.avi" generates a proper-length video (10 seconds), but the video frame never changes. (It's a still image)

    Test file and test output file :

    I think this is primarily caused by the fact that the IP cameras may only generate 5-7 fps but the security software doesn't know better and writes it as if it should be 24/30 fps.

    FFMpeg Reports : [m4v @ 00000000002cec60] Estimating duration from
