  11 octobre 2014, par skat

  I’m having issue with converting mov files from iPhone 4.

  Running this command :

  My ffmpeg gives me errors like this :

  Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)

  It’s only happening for mov files. There are couple of tricky places it looks like it’s trying to take screenshot from a video.

  Maybe anyone witnessed anything similar and can give me a tip ?
