  • h.264 video in mp4 container jumps when played in VLC

    30 avril 2013, par Jayanth Nayak

    I have H.264 video and AAC audio generated in Andriod phone recieved wirelessly using SIP protocol and muxed using FFMPEG APIs, The generated mp4 when played through VLC or other player is never in Sync.
    when I see the time bar of Video, it skips after a certain duration.

    For example :
    in a video of 20s, the time bar seeks upto 14s properly, then it jumps to 18s and finishes at 20. The audio plays properly.

    I have following questions :

    1. Is PTS DTS calculations really required for muxing WITHOUT Encoding ? :

    we used

    PTS = (90000 * (1/FPS) * FrameNumber) - although this did not work :(

    currently FFMPEG is taking care of it internally.

    1. Why the video jumps ? is it because of less number of frames or wrong PTS values or something else ?

    1. For the following cases although There is jump, I am getting a good AV sync
      -15,20,25 FPS qCIF & AAC Audio

      But for 15 & 20 FPS of qVGA & VGA the audio lags by 0.5 seconds and for 25 FPS, the Video is just playing fast.
      thus why is there a delay for qVGA and VGA but not present for qCIF ? any dependency of Resolution on Time Stamp (PTS) calculation ??

      Analysis of 25 FPS Video showed that there are enough number of frames for 10s but the total time for the video shown by VLC is 14s. Why is this so ? and again, this video also jumps from 9s to 13s.

  • Determine video bitrate Python

    7 juin 2021, par Thunderssucks

    I have a video downloaded from Telegram and I need to determine its bitrate.
I have moviepy (pip install moviepy, not the developer version).
Also, I have ffmpeg, but I don't know how to use it in python.
Also, any other library would work for me.

    


  • How do I install FFMPEG inside Railway ? :(

    8 décembre 2022, par Othman Alkhatib

    I am working on a telegram bot and I am using ffmpeg to split some videos.

    


    I can run the code on my local machine with no errors and the bot is responding correctly, but when I deploy project to railway and request the bot it says No such file or directory: 'ffprobe'.

    


    I think there is something like buildpack to be added to railway but I am beginner to railway server.
