  • Add custom metadata tag to video file without altering anything else

    9 juin 2020, par salgarji

    I'm modifying DASH-formatted segments, and my aim is to add extra information to the video segment using metadata tags.

    



    I'm using ffmpeg to record video from my webcam and store segments named like : init-video0-0.mp4 for the initial and video-0-0-N.mp4 for the following, where N is the segment number (beginning at N=1).

    



    For ffmpeg to 'understand' video files, they must have a playable video file format, for that purpose I concat initial segment with Nth segment :

    



    cat init-video-0-mp4 video0-0-N.mp4 > video0-0-N_mod.mp4


    



    Once I have a proper/correct file, I can use ffmpeg to add tags.
I've tried the following command :

    



    ffmpeg -y -i /path/to/file.mp4 -movflags use_metadata_tags -metadata customtag='whatEverYouWantToAdd' /path/to/new/file.mp4


    



    My problem is that the ffmpeg modifies the file changing other information regarding start, duration, progressive and fragmented flags...

    



    I've used this tool : https://download.tsi.telecom-paristech.fr/gpac/mp4box.js/filereader.html, to analyze my files in a more intuitive way :

    



    enter image description here

    



    Do you have any clue on how to add tags without altering DASH segments in any other way ? Even if it requires using another tool different from ffmpeg.

    



    Thank you in advance !

    


  • FFmpeg : Continuously download X minutes video from livestream ?

    16 février 2017, par Dorin Pleava

    I want to download X minutes from a livestream continuously and overwrite the same file, meaning the file will always have the latest X minutes from the livestream.

    Is there a way without calling the following command over and over again in a batch file ? Something that runs continuously from FFMPEG ?

    -i http://iphone-streaming.ustream.tv/uhls/17074538/streams/live/iphone/playlist.m3u8 -t 60 -y -c:a copy MyVideo.mp4

  • How do I access the ipod-library for decoding ffmpeg ?

    16 janvier 2014, par M_On

    Thank you to look at my question.

    There is a problem with too slow to access the music file using ffmpeg.

    Get the URL of the music that is in the ipod-library by using the 'valueForProperty:MPMediaItemPropertyAssetURL' method.

    Use the (AVAssetExportSession Class) TSLibraryImport.m, extract the music files from ipod-library.

    However, I took the extraction time is too long. (4 seconds of the 3GS iPhone, iPhone 5 is 1 second)

    It was not possible to be decoded using FFmpeg If you do not the Export.

    In order to use FFmpeg, it's AVPlayer can not be used.

    I will never forget the grace if you can answer if you folded to know how other maybe.
