  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • 1 movie to 14 part video / 1 Subtitle [closed]

    10 avril 2020, par Tayfun Erbilen

    I just cut my one long movie to 14 piece with ffmpeg.

    



    And now, I don't know how to show subtitle.

    



    Subtitle was for full version, but now I have 14 pieces and I don't know how to fit subtitle to these parts. By the way, I want to show on web. I'm using jwplayer for videos, but still I didn't figure out subtitle issue.

    



    Is anyone suggestion ?

    


  • 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 ?
