  • Not able to play .mpd file of MPEG-DASH stream

    29 novembre 2018, par JAVA Coder

    I have made segments of a mp4 file and uploaded all .m4s segments,.initmp4 file and the .mpd file to s3 bucket and used the url of .mpd file to play the full file using online DASH players of akamai,bitmovin,videoJs,dashJs etc but failed.

    When I tried to play the .mpd file by using GPAC MP4Client on command prompt just can hear the audio with a blank screen.

    You can find the commands here which I have used to make segments of the mp4 file.

  • 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.

    


  • 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.
