  • FFMpeg generating screenshots drop frames

    6 octobre 2011, par Morgan

    I'm using FFMpeg to extract frames from a video file, and for most videos it works flawlessly. But certain videos it seems to have to seek to the position that I want to take the screenshot from, and drops all the frames on the way there taking quite a while if the position i'm generating a screenshot from is near the end of the video. Here is the command I'm using to extract my screenshot.

    ffmpeg -ss 60 -i input.mkv -vframes 1 -f image2 -an -r 1/5 output.jpg

    and the output I receive

     Modify /vp9/encoder/vp9_speed_features.c



    Allow full coeff probability model and cost update

    This commit moves the simplified coefficient probability model
    and costing update to speed 4, and turns on chessboard pattern
    mode search for sub 720p sequences. The overall coding performance
    of speed 3 is improved :
    derf 0.889%
    stdhd 1.744%

    The speed 3 runtime for test sequences are improved :
    bus cif at 1000 kbps 9823 ms -> 9642 ms
    pedestrian 1080p 2000 kbps 189559 ms -> 183284 ms
