  • FFMpeg SetSar value gets overriden

    8 décembre 2015, par user650922

    I have a video concatenating application where In all videos are converted to the same format .

    I am converting 640*360 video to 1080*720 with setsar=1:1 as

    ffmpeg -i C :\Users\work\Desktop\Esocializ\B.mp4 -s 1080*720 -ac 2 -vf setsar=1 :
    1 -acodec aac -strict experimental B1.mp4.

    However for some reasons its value get overridden.

    Any help would be appreciated .

    Below is my console output :

  • FFmpeg extract N images from a video

    18 février 2015, par Ben

    I’ve been searching everywhere to work out how to extract N images from a video using FFmpeg. All the answers involve playing with the rate setting (-r). However, I’m having some fundamental problems with the rate. According to the docs, the following should produce one frame per second.

    ffmpeg -i input.mov -f image2 -r 1 preview-%d.jpeg

    If input.mov is 7 seconds long, I would expect to get 7 images. However, I get 10. I also tried on a video 119 seconds long, but I got 122 images. I’m getting 3 more images than expected. What am I missing ?

    For example, with this 3 second video I get six frames https://www.dropbox.com/s/8eke6q2gz1kgk1f/example.mov?dl=0

    benblack$ ffmpeg -i example.mov -f image2 -r 1 preview-%d.jpeg
