  • 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.

  • Live streaming application using ffmpeg and C#

    I am building an c# application for live streaming. I am able to stream the feed from web cam to rtmp server using ffmpeg but unable to display it on screen at the same time.

  • How to setup live video stream from webcam to the server, and then beyond ? [closed]

    15 mai 2020, par Parth Sarthi

    I have an application, that is written in Node and Nuxt, to host online exams. My clients are now demanding youtube like livestream for their students. I can't use WebRTC because there will be thousands of students watching the live video, so I don't think teacher's bandwidth will be able to deliver that.

    



    Now I want to know what other options do I have ? How do I send video stream from teacher's laptop to the server in real time ? I am assuming getUserMedia ? Then how do I convert the live stream incoming from the teacher into something like HLS ? I am assuming ffmpeg ? but what commands will do that actually ? cause i can't seem to find any which will take in Media Stream and convert it into HLS. And lastly how do I server it back to the students.

    



    I have already setup the live chat for every classroom with socket.io so I am stuck here.

    


  • Use specific channels from specific streams for the final stream using FFMPEG [closed]

    9 juin 2024, par Kazu-kun

    I want to create a 5.1ch audio stream from a 2ch audio stream. However I want to put a negative delay to LFE, SL and SR channels since they will be played from my bluetooth speaker, so I want to make up for the delay by giving it a negative delay.

    


    


    ffmpeg -itsoffset 0.1 -i input.mkv -i input.mkv

    


    -filter_complex “

    


    [1:a]pan=5.1(side)|FL=FL|FR=FR|LFEp>


    [0:a]pan=5.1(side)|FL=FL|FR=FR|LFEp>


    [orig5_1][delayed5_1]amerge=inputs=2,pan=5.1(side)|FL=c6|FR=c7|LFE=c2|SL=c3|SR=c4[a]”

    


    -map "[a]" -map 0:v -map 0:s -c:v copy -c:a flac -c:s copy output.mkv

    


    


    I tried taking the same input twice with the first one being delayed by 0.1 secs. With the delayed input a 5.1 audio is created and with the original another 5.1 audio is created as well. Then the two audio streams are merged with amerge and combined into a single 5.1 audio by taking delayed channels for FL and FR(These will be played from my MacBook) and by taking original channels for LFE, SL and SR(These will be played from my bluetooth JBL). Finally the video and subs streams are taken from the delayed.

    


    The above command gave a "pipe pipe pipe dqoute" error and when I entered the command again it said :

    


    


    zsh : unknown file attribute : i

    


    zsh : no such file or directory : FL+FR

    


    zsh : unknown file attribute : i

    


    zsh : no such file or directory : FL+FR

    


    zsh : unknown file attribute : i

    


    zsh : command not found : -map

    


    


    Please give me a command for my requirement !
