  • How to create an animated seekbar on top of video using ffmpeg [duplicate]

    13 décembre 2019, par Rehan

Please provide an example command either using ffmpeg or node-fluent-ffmpeg. In simple words any stylish seekbar those are used these days in social media videos.

  • How to add a ten seconds of still images to an mp4 file using any tool ?

    22 mars 2021, par Tebyan

    Is there a way to insert some images or a video to an mp4 for 10 seconds and freeze the rest of the video so it doesn't get read by a media player ? I am not sure if I can explain this correctly but I have been doing searches about mp4 structure an seems like there are not much sources to explain it. I have read about moov/trak/mdat and some other atoms (The basic elements that makeup an mp4 file). So the question shall be how to configure the Trak atom to only play 10 seconds of data inside the mdat atom and the other data should be inside mdat atom but not playable until you programmatically again remove or disable the ten seconds data and configure the trak to play the rest of the file. However that's what I think might be possible so if anyone knows any other kind of way to do pretty much the same thing (it might be encryption) please share. And also I am not much to video codes and stuff so if any names that you think might be foreign to someone with less knowledge about videos please explain it too.

    


  • FFMPEG encoding example does not work with VPx encoders

    11 septembre 2018, par user4177870

    I am using the following example from FFMPEG to write a raw steam of VP8 or VP9 encoder :
    https://ffmpeg.org/doxygen/trunk/encode_video_8c-example.html

    The VP8 or VP9 based file is written successfully to the disk. Then to mux this stream into a container, I sued FFMPEG command line :

    ffmpeg -i myfile.vp9 -c copy testvideo1.mkv

    I get the following error when I run the above command :

    ffmpeg version N-91789-g11cec34829 Copyright (c) 2000-2018 the FFmpeg developers

    myfile.vp9 : Invalid data found when processing input

    However, when I run the above set of operations for h264, its works fine.

    I assume its because of the endcode = 0, 0, 1, 0xb7 which might not work for VPx encoders.
    Not sure whats the issue. Any help would be appreciated.
