• Rails FFMPEG - convert to webm gives error for encoder 'libvpx-vp9'

  7 mai 2019, par Milind

  I am testing video conversion to convert video file into mp4 and webm.
  I have also setup ffmpeg and compiled properly.Mp4 conversion succeeds but webm breaks always complaining as -

  The encoder 'libvpx-vp9' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.

  its strange as I aready have vp8 present -

  mike1011:~/workspace (s1) $ ffmpeg -encoders | grep -i vp

• FFMPEG images to video outputs junk

  15 décembre 2019, par GreatCorn

  I’m very new to using FFMPEG and I’m trying to make an image sequence into a video. However, none of my attempts were succesful. I first tried 825x480 .pngs which resulted in and then 512x512 .jpgs, pretty much the same result. I tried a few codes like ffmpeg -framerate 24 -i img%03d.png output.mp4, ffmpeg -r 1/5 -framerate 24 -i img%03d.png -c:v libx264 -vf -pix_fmt yuv420p output.mp4 and etc. I just don’t really understand what I’m supposed to do to prevent this.
