FFmpeg mjpeg Argument

I recently posted about extracting jpeg frames from video files. I received an email from a reader who was having problems with the singlejpeg argument. It turns out that the latest version of FFmpeg doesn’t support this argument, which has now been replaced by mjpeg. I haven’t had the opportunity to upgrade, but if you run into problems be sure to give this a try.

   And if you do, follow these tips (man I need a blog):

   - Don’t use the -ss argument. Just doesn’t work (though ffmpeg seems to complete successfully no file is created)
   - The name of the file must include a %d (it will be replaced with the frame number). IMO, this is a bug.

   Here’s my working ffmpeg options (replace the %s with your input and output file paths):

   ffmpeg -i %s -vframes 1 -an -s 320×240 -t 00:00:05 -y %s

   HTH,

   Dave,

   Thanks for the feedback. I’ll run some tests and follow up with a post shortly.
