  • ffmpeg decode and encode for an extension typo

    15 novembre 2022, par William Wong

    I am trying to download some videos from an m3u8 file online. However, the .ts files were (maybe intentionally) changed to .png files. I have tried downloading the .png files and changing them to .ts manually and it plays well.

    


    However, the ffmpeg file seems cannot parse the .png files. I tried to force the output format with -f, but it does not work.

    


    May I know if that is possible to still use the ffmpeg for downloading and converting the stream to mp4 ? I am also open to other methods or simple fixes with bash/ python.

    


  • How to calulate PTS and DTS ? 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.

    


  • Is there any way to concatinate multiple video and audio streams with offset ?

    17 avril 2019, par Demchenko Oleg

    I am sory for my english, it is not my mother language. My issue related to ffmpeg concatenation of audio and video streams. There are multiple audio and video streams which were recorded by online chat. All of them have start and end time points. If user turned off a micro or camera then audio and video streams wouldn’t be matched. How can I align all streams in one time series ? Can I add some white noise to separate the two videos ? Similar with audio.
