  • Other interesting software

    13 avril 2011, par

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • Use ffmpeg to watermark and scale an image on video

    11 mai 2015, par Ae.

    I want to be able to watermark videos with a logo image, which contains a website url.
    The videos can be of different formats and dimension.
    I’m trying to figure out a generic ffmpeg command to achieve it, so that i don’t have to tweak the command depending on the video i have to process.
    So far i got :

    ffmpeg -i sample.mov -sameq -acodec copy -vf 'movie=logo.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]' sample2.mov

    In this way though the logo will look too big or too small with video of different size.
    I’ve seen there is a scale option for avfilter, but I haven’t figure out whether it’s possible to resize the image logo based on the dimension of the input video, so that I can say to scale the logo to 1/3 of the video length for example, and keep the image ratio.

    Any idea ? doesn’t need to be done in a single command, could even be a script.
    thanks in advance.

  • encoding jpeg as h264 video

    22 février 2017, par jefftimesten

    I am using the following command to encode an AVI to an H264 video for use in an HTML5 video tag :

    ffmpeg -y -i "test.avi" -vcodec libx264 -vpre slow -vpre baseline -g 30 "out.mp4"

    And this works just fine. But I also want to create a placeholder video (long story) from a single still image, so I do this :

    ffmpeg -y -i "test.jpg" -vcodec libx264 -vpre slow -vpre baseline -g 30 "out.mp4"

    And this doesn’t work. What gives ?

    EDIT : After trying LordNeckbeards answer, here is my full output : http://pastebin.com/axhKpkLx

  • how to insert the play button in the video thumbnail ?

    12 février 2012, par Vijay

    I'm creating thumbnails from videos using ffmpeg and it's working fine.

    But now I want to add a play button image at the center of the thumbnail image and store them.

    I've used CSS to get that, but I want to know whether there is any method to create thumbnails with the given image at the center.
