• Can I reduce buffering and delay using ffmpeg ?

  28 juin 2021, par Trivalio

  I'm currently working (as a total beginner) on a nginx-RTMP streaming server and i've tried to implement ffmpeg filters but as i tested them i saw that there is a lot of delay due to these filters.
I'm having a hard time finding a ffmpeg function to reduce it.
Here is what i've done so far :

  


  worker_processes auto;
rtmp_auto_push on;
events{}
rtmp{
    serveur{
        listen 1935;
        listen [::]:1935 ipv6only=on;
        chunk_size 4096;
        buflen 5s;
        application live{
            live on;
            record off;
        }
        application ffmpeg{
            live on;
            record off;
            exec /usr/bin/ffmpeg -re -i rtmp://localhost/$app/$name -vf mpdecimate,hue=s=0 -vcodec flv -acodec copy -f flv rtmp://localhost/live;
        }
    }
}


  


  i use OBS to stream to the ffmpeg application and i use VLC to see the stream exiting from the live application.

  


  I've tried many functions from rtmp but since the delay doesn't seems to come from rtmp, it doesn't change anything.
If you have any idea how to improve that, you will make me a quit happy person.

  


  Thank you !

  


• Create a RTSP video stream on a .NET platform

  12 décembre 2012, par Goro

  I want to create a RTSP/h264 video stream from static images, and incorporate it into my .NET application. So far I have found two possible ways to do this :

  1. Use ffmpeg/ffserver, but I would need to compile ffserver on windows and then rely on it... and I don't necessarily want to rely on an external application

  2. Use the LIVE555 (http://www.live555.com) library, but they do not have any .NET libraries, so I would need to spend some effort to make it work with the rest of my .NET application.

  Can you comment on either #1, #2, or which is better. Is there a faster way to bring up a RTSP server in .NET ? I do not mind putting in development time if there is a solid solution that takes time, but it would be good to have something we can work with fast, for prototyping and demos.

  Thank you,

• scalability issues with video encoding on webserver

  2 janvier 2013, par Prasanth

  On a web application that im creating the user is allowed to upload a video. The video is converted to x264 using ffmpeg for iOS playback. So if there are too many users thats going to kill the web server.

  I'm thinking about something like this. Have a few encoding servers for the application and the application on receiving the video file uploads to any one encoding server and the encoding server encodes the video and uploads it back to the web server.

  Are there any other solutions preferably which wont increase the response time for the user ? The user has to see the preview of the video as soon as the upload process finishes.

  The client does not want any 3rd party video encoding services. We have negotiated this many times but they do not want this.
