    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • ffmpeg : Combine/merge multiple mp4 videos not working, output only contains the first video

    22 janvier 2017, par dtbaker

    Here is the command I am using to combine multiple videos :

    ffmpeg -i 75_540_38HQ2.mp4 -i 76_70_20.mp4 -i 76_173_80.mp4 -i 81_186_35.mp4 -vcodec copy -acodec copy Mux1.mp4

    The resulting Mux1.mp4 does not contain all videos. Only the first video (75_540_38HQ2.mp4). The file size of the source and resulting video is below (as you can see, resulting video is slightly larger than first vid) :

    $ ls -lh
    
    - rw-r—r— 1 dbaker dbaker 42M 2011-03-24 11:59 75_540_38HQ2.mp4
    - rw-r—r— 1 dbaker dbaker 236M 2011-03-24 12:09 76_173_80.mp4
    - rw-r—r— 1 dbaker dbaker 26M 2011-03-24 12:05 76_70_20.mp4

    - rw-r—r— 1 dbaker dbaker 44M 2011-03-24 14:48 Mux1.mp4

    Here is the output of the ffmpeg command. To me it looks ok, showing the multiple source inputs and the single output.

    Am I doing something blindingly stupid here ?

    The source videos came from a video camera, and are small snippets taken with ffmpeg -i bigfile.mp4 -ss 20 -t 10 -vcodec copy etc..

    Thanks heaps !!
    Dave


    Edit : couldn’t solve it so I just use avidemux GUI tool. It seemed to append the MP4’s just fine.

    Must be a problem with MP4’s or just the ones that come off a gopro camera.

  • How do I download the image with metadata in Python ? [closed]

    19 octobre 2024, par Temp Account

    I am downloading some images in Python from the Airtable API and am trying to make a slideshow with them using ffmpeg. I download the images :

    


    urllib2.urlretrieve(img['url'], "output/images/image_"+str(i)+".jpeg")


    


    However, when I run the following ffmpeg command

    However, downloading the images in Chrome then creating the slideshow is successful. The images from Chrome have metadata of the filetype (JPEG), width and height. The images downloaded with Python have no metadata. How do I download that information so that my ffmpeg command will succeed ?

    


    Thanks !
