  • ffmpeg Grab Single Frame From Youtube Stream

    11 septembre 2021, par Rich_F

    I'm trying to grab a single frame of a streaming video on Youtube.

    


    This is an example

    


    This is the code structure I'm trying to use :

    


    ffmpeg --verbose -i $(youtube-dl -f 96 --no-playlist 'https://www.youtube.com/watch?v=XMs6LnT5mfk') -frames:1 -pred 1 clip1.jpg


    


    Trying to use youtube-dl to grab part of a stream, doesn't seem to work, and is actually throwing an ffmpeg error at me :

    


    [youtube] Q-44KECp-xQ: Downloading webpage
[youtube] Downloading just video Q-44KECp-xQ because of --no-playlist
[youtube] Q-44KECp-xQ: Downloading m3u8 information

[download] Destination: Ryde Esplanade & Pier, Isle of Wight UK _ Railcam LIVE 2021-09-11 03_25-Q-44KECp-xQ.mp4

ERROR: ffmpeg exited with code -9


    


    How can I achieve this ? I'm open to reworking this approach, or moving to something completely different. Cheers

    


  • How can I add custom metadata to an MXF using FFMPEG ?

    15 septembre 2021, par Zak44

    I am trying to add custom metadata to an MXF in FFMPEG. I can get the syntax to go through and then my metadata to be listed during the command output, but when I later run FFMPEG on the file to check the metadata is not there. Only the material_package_name will stick. Is this not possible with MXF ?

    


    Command :

    


    ffmpeg -i Test.mp4 -vf scale=1920:1080 -an -metadata project="TEST PROJECT" -metadata comment="Test Comment" -metadata artist="Test" -metadata material_package_name="TEST VID CLIP" -b:v 36M -f mxf_opatom "TEST_VID_CLIP.mxf"


    


    Output from command :
