  • Use ffmpeg to extract picture from m4v file

    31 octobre 2017, par Brian

    I used a program called MetaZ on my mac to tag all my video files (m4v). I am now trying to use these m4v files in Kodi which requires .nfo files and separate picture files for movie posters, etc. I want to extract the picture that is already in the m4v file.

    When I use ffprobe -show_streams, I can see that index4 is a png file (codec_name=png). How do I extract it ? I believe ffmpeg can do it, but can’t figure out how.

    Here is the output from ffprobe :

    This commit is a noop.
    

    [11:00:43] <jamrial> michaelni : what do you think of 8f5de34c8f ? does it apply to us ?
    
[11:01:50] <jamrial> our code started to deviate with your commit bca59d7745e, followed by the merge commit aa40df483b2
    
[11:33:51] <michaelni> jamrial, the fade commits are from 2013, but i think our fixes where complete and the problematic slice_h FFALIGN is also removed

  • "File doesn't exist" - streamio FFMPEG on screenshot after create method

    3 mai 2013, par dodgerogers747

    I have videos being directly uploaded to S3 using Amazon's CORS configuration. Videos are uploaded via a dedicated S3 form, once they have been uploaded successfully the URL of the video is appended to the @video.file hidden_field via javascript and then the video saves.

    I can't get this after_save method to work which takes a screenshot of the video and saves it to S3 via carrierwave after the video has been saved as a rails object. ( It was previously working using a carrierwave video upload instance )

    It errors out withErrno::ENOENT - No such file or directory - the file &#39;http://bucket-name.s3.amazonaws.com/uploads/video/file/secure-random-hex/video_name.m4v&#39; does not exist: I have tried running this method as a class method to call it from the console but it always comes back with the same error, even though the video exists.

    My bucket is set to public, read and write. How come it doesn't think the file exists ?

    If anyone needs more code just shout, thanks in advance.
