  • Configuration spécifique d’Apache

    4 February 2011, by

    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel;
    Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

  • Trying to stream webcam with VLC, video works but no audio

    19 August 2021, by MirceaKitsune

    I created a bash script a while back to stream my webcam to http with VLC. The line I used was:

    


    cvlc -vvv v4l2:///dev/video0 input_stream --sout '#transcode{vcodec=MJPG,vb=0,scale=1,acodec=none}:standard{access=http,mux=mpjpeg,dst=:1234}'


    


    That works fine but no audio. I've been trying to update it to capture sound from the webcam as well, but nothing I do seems to get that working. I know the ALSA address of the mic which is "hw:2,0" and using the arecord command as a test confirms it works, it's just vlc that isn't capturing or streaming accordingly. Here's the latest command I managed to work out, video is functional but no audio:

    


    cvlc -vvv v4l2:///dev/video0 alsa://hw:2,0 --live-caching=5000 --sout '#transcode{vcodec=h264,vb=1024,acodec=mpga,ab=128,samplerate=44100,channels=2}:standard{access=http,mux=ffmpeg{mux=flv},dst=:1234}'


    


    What is wrong with it and how do you recommend improving this? Thanks.

    


  • FFmpeg audio behind video. Video from IP camera, Audio from microphone

    4 August 2021, by Evgeniy Russkih

    I'm trying to mix audio and video from different sources.
Video from camera via h264-converter and audio from microphone.
Unfortunately audio is stitching behind video for about 1-2s.
After that stream is supposed to be shown in browser with smallest delay possible, so adding -itsoffset would not going to work.

    


    Here is my command:

    


    


    ffmpeg.exe -r 30 -fflags nobuffer -i http://192.168.88.168/0.ts -f
dshow -i audio="Microphone (Realtek)" -acodec mp2 -ac 1 -f mpegts -r
30 -c:v mpeg1video -b:v 3200k
http://localhost:5000/upload/ae7e32f660b6427a9b6d9ab6abf4cf19

    


    


  • How to stream a video from localhost to web browser using video tag?

    31 July 2021, by kup

    Basically what i want to stream a video to my browser both on localhost, using flask and opencv or ffmpeg.

    


    But not sure how to do it.

    


    i tried this:

    


    #!/usr/bin/env python
from flask import Flask, render_template, Response
import cv2
import sys
import numpy

app = Flask(__name__)

def get_frame():
    c=cv2.VideoCapture("output.mkv") 

    while True:
        retval, im = c.read()
        imgencode=cv2.imencode('.jpg',im)[1]
        stringData=imgencode.tostring()
        yield (b'--frame\r\n'
            b'Content-Type: text/plain\r\n\r\n'+stringData+b'\r\n')

    del(c)

@app.route('/vid')
def vid():
     return Response(get_frame(),mimetype='multipart/x-mixed-replace; boundary=frame')


if __name__ == '__main__':
    app.run(host='localhost',port=5000, debug=True, threaded=True)


    


    but its not working may be because it is sending images, how can i stream video?
