  • What's right way to change playback speed with ffmpeg ?

    25 août 2016, par user2440195

    In my project i’m using ffmpeg to playback media. Currently I’m trying to implement changing of playback speed. Will it be right to drop certain packets at high rates, for example not keyframes ? Or I should rely only on changing timestamps and duration, even if performance is low(for example 4k video) and as a consequence increased speed isn’t noticable ?

  • FFMPEG Speed up video (loss of audio is fine)

    14 mai 2015, par adsun

    I’m trying to speed up a video by 2X by using this command.

    ./ffmpeg -i input.mp4 -filter:v setpts=(1/2)*PTS output.mp4

    But I get the following error :

    Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height

    Can someone help me with the correct command to do it ? The input video is a valid MP4 file. It is fine even if there is no audio in the video after speeding up.
