  • What to input for variable frame rate in pts / dts in ffmpeg

    23 novembre 2014, par William

    I am capturing frames from a webcam stream which sends frames in at a variable rate. My output video plays much faster than it was captured because there are less frames available than the input fps.

    I’m really new to ffmpeg and don’t know what to put into pts and dts. I can get an Int64 representing nanoseconds since 1600 when the frame arrives. How do I use the av_rescale_q function with it ?

    Reading online it seems a solution may be to clone frames so the output fits into a constant frame rate video. However it would be better just to put the timestamp in there.

  • "FFMPEG not found" even though ffmpeg-binaries have been added to the package.json

    17 août 2018, par Xyvyrianeth

    I keep my bot online using Heroku, so installing FFMPEG to my computer wouldn’t really help me any.

    The issue is that I’m still getting this error despite having the npm ffmpeg-binaries added to my package.json’s dependencies. I’ve also tried using git URLs from Github and the official FFMPEG website, as well as trying to install the git directly using the run-command option in Heroku’s application page, but I keep getting this same error. Am I missing something ?

  • How to calulate PTS and DTS ? FFmpeg C++

    27 janvier 2024, par kodoma

    I have a mkv file where I want to extract the video stream. While extracting, I got the "... non monotonically increasing dts to muxer ..." Warning/Error. I have tried multiple solutions that I found online, but I could never get the timing to be right.

    


    This is the beginning of the video stream :

    


    DTS: 0    PTS: 0    Duration: 41 
DTS: 375  PTS: 375  Duration: 41 
DTS: 209  PTS: 209  Duration: 41 
DTS: 42   PTS: 42   Duration: 41 
DTS: 83   PTS: 83   Duration: 41 
DTS: 125  PTS: 125  Duration: 41 


    


    I also extracted the stream via the FFmpeg executable, and the extracted video file has the same DTS and PTS as the source.

    


    So how do I calculate the DTS and PTS correctly ? If I don't change the timings, the video is the same length, but it is total garbage.
