  • Creating farms of unique websites

    13 avril 2011, par

    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 package not found

    29 février 2024, par elbarto

    I'm running on a Ubuntu 22.04 VM (host : Windows 10).
I have a precompiled c++ code which requires a certain version of ffmpeg, which wasn't initially installed on the machine (wondering why).
I found out that the version I needed was the FFMPEG 2.8 (as the ldd command suggests).
For example, the application requires libswscale-ffmpeg.so.3 or even libavutil-ffmpeg.so.54 (that's why the ffmpeg version I guessed was the 2.8).

    


    Since I couldn't install that specific version from a single command line, I installed it from github (https://github.com/FFmpeg/FFmpeg/blob/master/INSTALL.md)

    


    I also used the --build-suffix=-ffmpeg as another topic suggested, and the installation worked as expected (I guess ?)

    


    However, I don't find any other ffmpeg subpackage like libswscale.ffmpeg.so.3 or others.

    


    How can I fix this problem ?

    


  • Converting PNG images to MP4 in Jupyter

    15 mars 2020, par Steve H

    This has had me going round in circles for hours, so I’m hoping one of you kind gents can help.

    I am trying to learn more about data science and have followed this course on creating a population pyramid (https://www.viralml.com/video-content.html?v=WmyYyOtZwzs). There were a few problems in the code, which I rectified, but one has eluded me.

    I am trying to convert a collection of images in the format anim_%d.png to an mp4 file using the code :

    ffmpeg -framerate 10 -i "anim_%d.png" -pix_fmt yuv420p out.mp4

    However, I get an invalid syntax error.

    I have also tried :

    avconv -f image2 -i anim_%d.png -r 76 -s 800x600 foo.avi

    then :

    ffmpeg -r 10 -i "anim_%d.png" -pix_fmt yuv420p out.mp4

    But they all give a syntax error.

    I am using Jupyter, via Anaconda on a Windows machine with Python 3.

    Any help would be greatly appreciated.

    Thanks

  • ffmpeg with Axis P1347 returns 400 Bad Request, but Axis 1357 works

    3 mai 2016, par steampowered

    I have two cameras : an Axis P1347 and an Axis P1357. ffmpeg gets a 400 Bad Request on the P1347 but everything works fine with the P1357.

    I am able to successfully stream rtsp video using vlc from an Axis P1347 Camera using the following url :

    rtsp://10.8.3.85:554/axis-media/media.amp?videocodec=h264&audio=1

    However, this same url in ffmpeg gives the following for the Axis P1347 Camera :

    root@ubuntu4-virtual-machine:/home/ubuntu4# ffmpeg -re -v verbose  -i "rtsp://10.8.3.85:554/axis-media/media.amp?videocodec=h264&audio=1"

    The same ffmpeg command works great with the nearly identical Axis P1357 Camera :

    Obviously rtsp is turned on and working if vlc can display video, correct ? So why does VLC work with the camera, but not ffmpeg ? Note ffmpeg is installed and works correctly with a similar camera.
