  • MediaSPIP v0.2

    21 juin 2013, par

    MediaSPIP 0.2 est la première version de MediaSPIP stable.
    Sa date de sortie officielle est le 21 juin 2013 et est annoncée ici.
    Le fichier zip ici présent contient uniquement les sources de MediaSPIP en version standalone.
    Comme pour la version précédente, il est nécessaire d’installer manuellement l’ensemble des dépendances logicielles sur le serveur.

  • 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 keeping quality when reducing FPS and streaming over RTSP with rtsp-simple-server

    25 janvier 2021, par Jens Schneider

    I'm using the rtsp-simple-server (https://github.com/aler9/rtsp-simple-server) and feed the RTSP Server with a FFMPEG stream.

    


    I use a docker compose file to start the stream :

    


    version: "3.8"

services:

  ffmpeg:
    container_name: ffmpeg-base
    restart: always
    image: "jenssgb/rtspffmpeg:base"
    depends_on:
      - rtsp-server
    volumes:
      - $PWD/:/video
    network_mode: "host"
    command: "ffmpeg -re -stream_loop -1 -i /video/footage-1-b.mp4 -c copy -f rtsp rtsp://localhost:8554/compose-rtsp"
  
  rtsp-server:
    container_name: rtsp-server-base
    restart: always
    image: "aler9/rtsp-simple-server"
    network_mode: "host"


    


    Now I'm trying to reduce the FPS of my video with transcoding it :

    


    command: -re -stream_loop -1 -i ${VIDEO_FILE} -vf "fps=${FPS_COMPOSE}" -f rtsp rtsp://localhost:8554/compose-rtsp


    


    This is basically working, but the quality of the output video becomes pretty bad. I tried a lot of things like -c:v libx264 which did help for a minute but let ffmpeg crash then.

    


    av_interleaved_write_frame(): Broken pipe0:00:09.99 bitrate=N/A speed=0.985x    
[rtsp @ 0x5563b1755640] Packets poorly interleaved, failed to avoid negative timestamp -33660 in stream 0.
Try -max_interleave_delta 0 as a possible workaround.
av_interleaved_write_frame(): Broken pipe
Error writing trailer of rtsp://localhost:8554/compose-rtsp: Broken pipe


    


    Any idea how I can reduce the FPS send the stream to the server but keep the video quality ? Later I'm going to reduce the resolution as well - but for now I want to keep resolution and quality but only reduce the FPS.

    


    Full logs from my test with -c:v libx264 :

    


        ffmpeg -re -stream_loop -1 -i footage-1-b.mp4 -vf "fps=5" -c:v libx264 -f rtsp rtsp://localhost:8554/compose-rtsp

  • FFMPEG Take 1 second clips each video file from a directory of files, and until total playtime reached

    3 février 2021, par Matthew

    I'm working on a music art video project for a song.

    


    I have a directory that contains approximately 400 individual videos

    


      

    • varying lengths (as short as 3 seconds and as long as 31 minutes)

      • 


    • varying file types (mp4 and webm)

      • 


    • varying resolutions/framerates/bitrates

      • 


    


    The output video should consist of :

    


      

    • 1 second chunks of each video

      • 


    • in round-robin fashion

      • 


    • until all videos are played fully or the output total video length reaches a certain limit (example, 20 minutes).

      • 


    • Output video should be 1280×720 at 24fps, with no preference to bitrate.

      • 


    • Videos that are larger should be scaled down and letterboxed (vertically or horizontally).

      • 


    • Audio is not important at all. The video can be silent. I can overlay audio separately.

      • 


    


    I do not want to loop short videos. In the example below, you can see that, for top-left-view-take-1.mp4, each 'clip' that's taken is incrementally further into the video. In other words, it shouldn't take the same 1 second clip from the beginning. The goal is to get further in to each individual video as the output video progresses.

    


    For example, say my directory contains files such as the following (and, for the example here, we'll say that this is all files in the directory) :

    


    overhead-view-take-1.mp4 (3 seconds, for the sake of the question)
top-right-view-take-1.mp4 (3 seconds, for the sake of the question)
top-right-view-take-2.mp4 (5 seconds, for the sake of the question)
outside-kaleidoscope-1.mp4
yellow-kaleidoscope-1.mp4
red-kaleidoscope-1.mp4
brake-lights-slow-1.mp4
soft-city-lights.webm


    


    Assume anything that isn't marked with a video duration is at least 5 seconds long.

    


    Based on the above files & times, here would be the order and time code of each clip during the first 30 seconds of the output video :

    


    Based on each video's total duration, the output video should include 1 second clips from all videos in the directory.

    What I've tried

    


      

    • I've read through the docs and cobbled together some code that produces output, but it only seems to work with images ; I can't get the same thing to work with videos (specifically the incremental chunks).

      • 


    • I've tried manipulating commands meant to `create a snapshot every x seconds/frames' but I've hit dead ends there.

      • 


    • I've also started trying to create a text file to run the input from. That's the point where I thought it would make sense to ask here.

      • 


    


    My main issue is picking off incremental chunks of individual videos, and playing those in sequence.

    


    Thoughts ?

  • .mp4 file is not playing in Django template and FireFox or Chrome

    9 février 2021, par Himanshu sharma

    I can save live RTSP video stream in .mp4 but when I run saved .mp4 video in Django template or Firefox or Chrome browser or VLC, video is not playing in ubuntu.
I think I have a compatible issue problem in .mp4. Furthermore, I want to show and play .mp4 saved file in Django.

    


    I have a two IP camera which provides a live RTSP video stream.
