  • Frame rate very high for a muxer not efficiently supporting it

    23 avril 2014, par DevDave

    I got an error when trying to run the following command with FFMpeg :

    -i "file1.mp4" -s 506x406 -b:v 2000k -ar 22050 "file2.mp4"

    FFMpeg was stuck converting this video, which was just a 7Mb .mp4 file, for hours and eventually I had to kill the process.

    The output error from FFMpeg is as follows :

  • Recording desktop with gdigrab ffmeg to mp4 file with too high video_size don't working

    4 juillet 2016, par tagry

    I try to recording my desktop with ffmpeg using the command :

    ffmpeg -f gdigrab -framerate 10 -video_size 1920x1200 -i desktop -pix_fmt yuv420p -vcodec libx264 -preset ultrafast output.mp4

    The problem is when the video_size option is higher than some size, (for example height higher 1089), the video can’t be read with Windows Media. I noticed that with this high size, the video which be recorded doesn’t have informations about size. I don’t understand why the record don’t work with a too big size. If somebody can help me.
    Thank you very much and very sorry for my English.
