  • 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" (...)

  • How to pass command line arguments to FFMpeg in iOS

    23 septembre 2014, par Arif Nadeem

    This is a beginner question, since I am new to iOS(I started it today), so please pardon my ignorance and lack of iOS knowledge.

    After building and successfully using FFMpeg for Android I wanted to do the same for iOS.
    So I built FFMpeg successfully for iOS by following this link, but after all that pain I am confused as how to use FFMpeg in iOS, I mean how can I pass command line arguments to libffmpeg.a file ?

    I am assuming that there must be a way to run the .a file as an executable and then pass command line arguments and hope for FFMpeg to do the magic, I did the same in Android and it worked beautifully.

    I am also aware that I can use ffmpeg.c class and use its main method, but the question remains ; how do I pass those command line arguments ?

    Is there something I am supposed to be aware of here, is the thing what I am doing now correct or am I falling short on my approach ?

    I wanted to mix two audio files, so the command for doing that would be ffmpeg -i firstSound.wav -i secondSound.wav -filter_complex amix=inputs=2:duration=longest finalOutput.wav, how do I do the same in iOS ?

    Can someone please shed some light on this ?

  • FFmpeg tee muxer

    14 février 2013, par deed02392

    I'm trying to use the Tee muxer recently introduced to FFmpeg, to both output a stream over UDP and render the output in an SDL window.

    This is because I want to measure latency in my live broadcast system between the input to FFmpeg and its output (i.e. the encoding process latency).

    Can anyone explain how to use it properly ? This is what I have tried :

    ffmpeg -re -i ......\sample_ipod.m4v -f tee "[f=mpegts]udp ://127.0.0.1:1233|[f=sdl]foo"

    I understood this should result in an output stream to UDP and that I could specify additional formats by enclosing like [f=sdl] to mean -f sdl. Then because the sdl muxer requires an argument (the window title) I provided this in the same way the example gives for the stream.

    Hope some FFmpeg expert can shed some light on this. I've even scanned the code that adds the Tee muxer to no avail.

  • Where is my ffmpeg stream getting saved to ?

    14 mars 2013, par Chris

    I'm just starting to explore ffmpeg (ultimately for use with openCV), and I'm running this command :

    root@beaglebone:/# ffmpeg -f video4linux2 -r 25 -s 640x480 -i /dev/video0 /out.avi

    At which point the camera indicator light turns on and it appears to be capturing. However when I end it with CTRL+C, the file is nowhere to be found.

    Any thoughts ?

    Full output :

    root@beaglebone:/# ffmpeg -f video4linux2 -r 25 -s 640x480 -i /dev/video0 /out.avi
