  • ffmpeg sdl output framerate too high

    1er juillet 2015, par dkrikun

    I’m using the following command-line to play a video via SDL :

    ffmpeg -i input.mkv -f sdl "Video"

    The video is being played too fast, ffmpeg prints that the framerate is 500 (not constant, just playing as fast as possible)
    I’ve tried to limit the framerate as follows, but none of this has any effect :

    ffmpeg -i input.mkv -r 25 -f sdl "Video"  
    
ffmpeg -i input.mkv -f sdl -r 25 "Video"  
    
ffmpeg -i input.mkv -framerate 25 -f sdl "Video"  
    
ffmpeg -i input.mkv -f sdl -framerate 25 "Video"  

    I’m using ffmpeg version ffmpeg-20150605-git-7be0f48-win64-static on Windows 7.
    ffplay input.mkv works pretty well.

    Thank you !

    EDIT : console output for ffmpeg -i input.mkv -r 25 -f sdl "Video" follows :

  • How can I compress and create mp4 video file from batch of images on hard disk using ffmpeg ?

    29 juin 2015, par Brubaker Haim

    In my directory I copied ffmpeg.exe to the same directory where all the images are.
    All images are bitmaps.

    Then in the command prompt windows I typed :

    ffmpeg -f rawvideo -pix_fmt yuv420p -video_size 1920x1080 -i \\.\pipe\mytestpipe -map 0 -c:v mpeg4 -r  out.mp4

    But I get error that there is no a directory name :

    \.\pipe\mytestpipe

    So I removed it and typed the same line without the pipe part.

    ffmpeg -f rawvideo -pix_fmt yuv420p -video_size 1920x1080 -i -map 0 -c:v mpeg4 -r  out.mp4

    Now there is no a directory name -map

    So I moved the -map 0

    ffmpeg -f rawvideo -pix_fmt yuv420p -video_size 1920x1080 -i -c:v mpeg4 -r  out.mp4

    Now I’m getting error :

    -c:v : Protocol not found

    I used this line with the pipe in my c# program as arguments to ffmpeg using ProcessStartInfo but now I don’t want to use pipes only in the command prompt to type it and compress and create mp4 video file.

    Edit I tried this now :

    ffmpeg -framerate 1/5 -i screenshot%06d.bmp -c:v libx264 -r 30 -pix_fmt yuv420p out.mp4

    And what I get is some errors :

    E:\screenshots>ffmpeg -framerate 1/5 -i screenshot%06d.bmp -c:v libx264 -r 30 -p
    
ix_fmt yuv420p out.mp4

    For those who can see. When i’m doing it on a single file for example : ffmpeg -framerate 1/5 -i screenshot000002.bmp -c:v libx264 -r 30 -pix_fmt yuv420p out1.mp4 or screenshot000003.bmp or screenshot000122.bmp it will work fine and create the video file. But when i’m doing this for all images i’m getting all the errors : ffmpeg -framerate 1/5 -i screenshot%06d.bmp -c:v libx264 -r 30 -pix_fmt yuv420p out.mp4 here is the results when i did on screenshot000002.bmp and it worked fine.

    When i’m doing it on a single image file it’s working fine like screenshot000002.bmp but when doing it on all the images screenshot%06d.bmp it’s giving me all the errors i mentioned above.
