  • 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.

  • WebM live streaming via DASH

    4 juin 2018, par ewack

    I am following the instructions here to try to make WebM live streaming via DASH. My input is from an Axis camera and it is streaming as h264 encoding. I am using node to spin up the ffmpeg processes. I am able to create the .hdr file and the .chk files. The .mpd file is even created but it’s empty and I get an error saying :

    Could not write header for output file #0 (incorrect codec parameters ?): Operation not permittedStream mapping: Stream #0:0 -> #0:0 (copy)

    Here’s all of my code :

    var express = require('express');
    
spawn = require('child_process').spawn;
    

    
var app = express();

app.listen(8080);

  • Large Panorama to Panning Video

    16 juillet 2022, par COOKIES

    What would be the most efficient way to create a video from a panoramic image that would for example have the size : 5000 width x 600 height px ?

    



    I created this GIF image that would explain things a bit better. Imagine that the video would be inside the red border. So the video would potentially be panning from left to right.

  • Streaming RTP packets using SDP to ffmpeg

    4 avril 2017, par Johnathan Kanarek

    I have RTP packets in node.js server and I want to forward them to ffmpeg.
    I generate SDP files in the node.js server side and execute ffmpeg with the SDP as input.

    SDP :

    v=0

    Command :

    ffmpeg -max_delay 5000 -reorder_queue_size 16384 -protocol_whitelist file,crypto,udp,rtp -re -i input.sdp -vcodec copy -acodec aac -y output.mp4

    Same with RTMP

    ffmpeg -max_delay 5000 -reorder_queue_size 16384 -protocol_whitelist file,crypto,udp,rtp -re -i input.sdp -vcodec copy -acodec aac -f flv rtmp://127.0.0.1:1935/live/myStream

    I get weird video that plays some vidoe, then get stuck, then plays some audio, back to video and so on, it never plays both video and audio together.

    BTW, when I created separate SDP files for the video and the audio and stream them as two inputs into the same output, I get valid stream but the audio is not in sync (about a second offset).

    ffmpeg -max_delay 5000 -reorder_queue_size 16384 -protocol_whitelist file,crypto,udp,rtp -re -i video.0.sdp -max_delay 5000 -reorder_queue_size 16384 -protocol_whitelist file,crypto,udp,rtp -re -i audio.1.sdp -vcodec copy -acodec aac -shortest -y output.mp4

    What is wrong with my SDP ?

    I tried changing analyzeduration, probesize, rtbufsize, vsync, framerate,
    I even tried to remap the streams using -map 0:v -map 0:a,
    nothing helped

    I also tried to use RTSP server, see log :
