• Converting Real Media with ffmpeg

  7 août 2013, par Eric Arenson

  I have a number of old crusty Real Media files I need to convert and was hoping to write a script to batch process them. I'm able to do a Real Media -> AVI conversion with FFMpegX, but when I try to replicate the conversion with ffmpeg, it always errors out with something like :

  [avi @ 0x10084fa00] Too large number of skipped frames 117425 > 60000

  It may have something to do with the funky format of these Real Media files :

  Does anyone have any tips on either how to find out what FFMpegX is doing to make the conversion work, or a better way to go about using ffmpeg to do this ?

  EDIT

  Including the ffmpeg command (thank you to @Mondain for teaching me about the stream mapping !) and output :
