  • ffmpeg seek calculating wrong byte range ?

    12 mars 2020, par user4455

    I’m running into an issue while trying to extract thumbnails from a movie file at a specific timestamp. Generally I’ve had no issues with this, but I’ve come across a set of movie files that are getting an error about the byte range requested (416 Requested Range Not Satisfiable).

    The odd thing is that the server is correctly returning the content length in the partial content request, yet when it requests the movie file it requests a length that exceeds that.

    This is a bit over my head, so I’m not sure what could be happening here. Any insight would be great.

    The Command :

    /usr/bin/ffmpeg -y -ss 1400 -i 'https://s3-us-west-2.amazonaws.com/my-bucket/mymoviefile.mp4' -qscale:v 2 -f image2 -vframes 1 -filter:v 'scale=192:108' -loglevel debug /data/www/storage/test.jpg 2>&1

    The Error :

    [https @ 0x22e1e00] header='HTTP/1.1 416 Requested Range Not Satisfiable'
    [https @ 0x22e1e00] http_code=416

  • 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 :

  • ffmpeg 1FPS extraction call spits out infinite images until disk is bricked on poorly-encoded movie

    12 juillet 2017, par John Allard

    This is one of the oddest things I’ve ever seen while using ffmpeg.

    This is the scenario - we are getting video footage from a IONODE ION-E100 encoder, the footage is encoded in h264. I can view the footage fine in VLC, and I can copy it over to another video using ffmpeg and -c:v copy. The issue arises when I try and extract one FPS from the movie using the following command :

    ffmpeg -i testmovie.mp4 -r 1 -vf 640:-2 -q:v 18 -loglevel error /tmp/tmp/extraction_%04d.jpeg

    What this should do is go through the movie and extract one frame per second, then dump the frames to the files /tmp/tmp/extraction_0001.jpeg, /tmp/tmp/extraction_0002.jpeg, ..., /tmp/tmp/extraction_000X.jpeg. It should end when it reaches the end of the video.

    Now the odd thing that happens when I run this command is that it will run in a tight loop, writing tens or hundreds of thousands of images to the disk until the disk is full at which point the command fails. All of the extracted images are the exact same as one another.

    Here is the ffmpeg stats output on the video

    So my question is, why does this video break ffmpeg ? Why does ffmpeg get caught up in a tight loop extracting images without ever making any progres towards the end of the video ?
