  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • 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.

  • FFMPEG Incredibly Slow On Windows Server 2016

    1er août 2019, par Ben Gardner

    I have a t2.small (2GB RAM, 1 vCPU) Amazon EC2 instance running a process using FFMPEG. It runs just fine ( 30 fps) on my computer (i7, 12GB RAM), but at around 2 fps on the server. Here’s the command :

    rescale_command = f'ffmpeg -i {srcVideo} -filter_complex \"scale={owidth}:{oheight}, setsar=1:1, pad={dim[0]}:{dim[1]}:{oofx}:{oofy}\" {destVideo}'

    I’ve tried uninstalling and reinstalling ffmpeg/ffprobe

    Edited per llogan’s request, I’ve also discovered that it’s relatively speedy towards the beginning (I’m rescaling 100 times over the course of the program) and slows down towards the end.

    It utilizes 100% of the CPU even from the beginning, though.

    Example command/output :
    ffmpeg -i media/8-1-2019/hi/dl-107.mp4 -filter_complex "scale=607:1080, setsar=1:1, pad=1920:1080:656:0" media/8-1-2019/hi/sl-107.mp4

  • Video cropping with FFMpeg on Android is very slow [duplicate]

    7 avril 2017, par Rami Jemli

    This question already has an answer here :

    What i tried :

    I am trying to implement video cropping on android using FFMpeg (ffmpeg-android).

    Here is the command I use :

    String[] complexCommand = {"-i", inputPath, "-strict", "experimental", "-vf", "crop=1080:1080:0:0", "-threads", "5", "-c:v", "libx264", "-preset", "ultrafast", filePath};

    The problem :

    Video cropping is working, but even though I am using all needed options to make the operation fast, it still takes a 1min long video the same duration to crop.

    How can I achieve better speeds ?
    Will I need to implement video cropping on server instead of device ?
    Is there another way to implement video cropping on Android instead of FFMpeg ?

    I understand that I can achieve better UX by letting the user edit a cropped TextureView/SurfaceView while doing the actual cropping in background, but I want to avoid this way as it takes more time.

    UPDATE

    Here is FFMpeg’s log output :

>> " -map "[res]" -preset ultrafast out.mp4

    (Basically add a bunch of animated overlays to the video)

    On PC this command takes about a second to execute (render speed is about 278 fps). But on Android device with Snapdragon 821 it takes about 10 seconds (about 30 fps).

    The curious thing is that whenever command is executing on PC, CPU load is around 90%, but on Android it’s less than 1% (see screenshot : initial spike is UI stuff plus loading binaries, afterwards ffmpeg was executing until 10 second mark)

    enter image description here

    I tried executing the same command, but writing to /dev/null
    instead of the file :

    ffmpeg -y -i video.mp4 -ignore_loop 0 -i overlay.gif -filter_complex `
    
>> "[0][1]overlay=x=mod((1080/4 + sin(t)*1080/4)\,1920):y=mod(t*300\,1080):shortest=1[res];`
