  • ffplay - change playback speed without re-encoding

    2 novembre 2016, par Timothy Tan

    I have some .264 video files that I would like to view at half playback speed, without encoding them into a new file. I remember using ffplay to do this in the past, but it was some time ago, and I can’t seem to be able to do it now. From lots of searching, this is what is supposed to work :

    ffplay -f h264 -vf "setpts=2.0*PTS" filename.264

    However this does not seem to change the playback speed at all. If I try :

    ffplay -f h264 -filter:v "setpts=2.0*PTS" filename.264

    I get an error message saying ’Failed to set value ’setpts=2.0*PTS’ for option ’filter:v’ : Option not found’.

    I specifically remember being able to do this before but cannot find any information about this now. Converting the videos is not really an option because the files are finicky and often cause an error halfway through converting, corrupting the whole file.

    Is there a simple solution to this problem ? Am I typing one of the commands wrongly ?
