  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • Using aler9/rtsp-simple-server, able to stream HLS from file but not from ffmpeg's stdin

    11 avril 2023, par Powercoder

    UPD : hehe, it actially works, but in chrome, not mozilla

    


    I want to display programmatically generated stream on a webpage in real time. For this I have rtsp-simple-server with RTSP and HLS enabled. I managed to publish a stream from file with command ffmpeg -re -stream_loop -1 -i file.mp4 -vcodec libx264 -f rtsp -rtsp_transport tcp rtsp://localhost:8554/mystream and see it at http://localhost:8888/mystream.

    


    But when I'm trying to do the same with python from the ffmpeg's stdin, I'm getting infinitely loading video instead of stream and browser console says "Uncaught (in promise) DOMException : The fetching process for the media resource was aborted by the user agent at the user's request". Here is my code :

    


    import random
import shlex
import subprocess
import time

import numpy as np


def main():
    width = 1024
    height = 720
    framerate = 1
    frame_duration = 1 / framerate
    cmd = shlex.split(
        f'ffmpeg'
        f' -y'
        f' -f rawvideo'
        f' -vcodec rawvideo'
        f' -s {width}x{height}'
        f' -pix_fmt bgr24'
        f' -r {framerate}'
        f' -i -'
        f' -r {framerate}'
        f' -force_key_frames expr:eq(mod(n,3),0)'
        f' -vcodec libx264'
        f' -crf 18'
        f' -preset ultrafast'
        f' -tune zerolatency'
        f' -f rtsp'
        f' -rtsp_transport tcp'
        f' rtsp://localhost:8554/mystream'
    )
    ffmpeg_process = subprocess.Popen(cmd, stdin=subprocess.PIPE)
    try:
        while True:
            image = np.full(
                (height, width, 3),
                (
                    random.randint(0, 255),
                    random.randint(0, 255),
                    random.randint(0, 255),
                ),
                dtype=np.uint8,
            )
            ffmpeg_process.stdin.write(image.tobytes())
            time.sleep(frame_duration)
    finally:
        ffmpeg_process.stdin.close()
        ffmpeg_process.wait()


if __name__ == '__main__':
    main()



    


    In the server's logs seems like no bad messages instead of single 404 status (is it just about favicon, right ?)

    How do I get my stream from python visible on a webpage ?

    


  • ffmgep stucks while merging two streams at input 0 [closed]

    3 février 2024, par Robi Tagore

    I tried to merge two streams downloaded before, I was using ffmpeg to combine them. I could use the path directly, but I felt it would'nt always be, so I read the steams, after I combine them,
everytime I run the code it std errs the following output, and creates merged.mp4 with 0 bytes, help me find the mistake

    


    code

    


    
const {spawn} = require("child_process");
const fs = require("fs")


var audio = fs.createReadStream("audio.aac")
var video = fs.createReadStream("video.mp4")



var ffprocess = spawn("ffmpeg",[
    '-y',
    '-i', 'pipe:0', 
    '-i', 'pipe:1',  
    '-c', 'copy',  
    '-f', 'mp4',    
    'pipe:2',   
])

video.pipe(ffprocess.stdin)
audio.pipe(ffprocess.stdin)


ffprocess.stdout.on("data")


ffprocess.stderr.on("data", (data) => {
    console.log(`ffmpeg stderr ${data}`);
});
  
ffprocess.on("close", (code) => {
if (code === 0) {
    console.log("FFmpeg process exited successfully");
} else {
    console.error(`FFmpeg process exited with code ${code}`);
}
});
