• support auto birate based on internet speed using nginx-vod-module

  30 juillet 2020, par Maurya Shubham

  Allow multiple resolution video streaming from single video url - It's possible with nginx-vod-module package or I need to create different-different resolution file and set them ?

  


  Currently I've manually crated master.m3u8 file.

  


  


  #EXTM3U

  


  #EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=2149280,RESOLUTION=1280x720 index-v1-a1.m3u8

  


  #EXT-X-I-FRAME-STREAM-INF:BANDWIDTH=2149280,RESOLUTION=1280x720,URI="iframes-v1-a1.m3u8"

  


  #EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=246440,RESOLUTION=320x184 index-v1-a1.m3u8

  


  #EXT-X-I-FRAME-STREAM-INF:BANDWIDTH=246440,RESOLUTION=320x184,URI="iframes-v1-a1.m3u8"

  


  #EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=460560,RESOLUTION=512x288 index-v1-a1.m3u8

  


  #EXT-X-I-FRAME-STREAM-INF:BANDWIDTH=460560,RESOLUTION=512x288,URI="iframes-v1-a1.m3u8"

  


  #EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=836280,RESOLUTION=848x480 index-v1-a1.m3u8

  


  #EXT-X-I-FRAME-STREAM-INF:BANDWIDTH=836280,RESOLUTION=848x480,URI="iframes-v1-a1.m3u8"

  


  #EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=6221600,RESOLUTION=1920x1080 index-v1-a1.m3u8

  


  #EXT-X-I-FRAME-STREAM-INF:BANDWIDTH=6221600,RESOLUTION=1920x1080,URI="iframes-v1-a1.m3u8"

  


  


  but when I crul video url the master.m3u8 file contain only one resolution.

  


  


  #EXTM3U

  


  #EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=4742713,RESOLUTION=1920x1080,FRAMERATE=30.000,CODECS="avc1.640028,mp4a.40.2",VIDEO-RANGE=SDR

• How to send RTP stream to Janus from NGINX RTMP module ? [closed]

  25 novembre 2024, par Matéo

  I'm trying to create a stream and display it in a browser. I have already configured NGINX with the rtmp module and my stream works very well with HLS (between 5 and 10 seconds of latency).

  


  Now I would like to set up a low-latency stream and that's why I have installed the janus-gateway webRTC server that allows to take in input an RTP stream and provide in output a webRTC stream.

  


  Here's the schema I'd like to follow :

  


  OBS -> RTMP -> Nginx-rtmp-module -> ffmpeg -> RTP -> Janus -> webRTC -> Browser

  


  But I have a problem with this part : "nginx-rtmp-module -> ffmpeg -> janus"

  


  In fact, my janus's server is running and demos streaming works very well in localhost, but when i try to provide an RTP stream, Janus don't detect the stream in the demos (it shows "No remote video available").

  


  Anyone can help me, please ?

• Generate EPG (Electronic Program Guide) with FFMPEG re-stream

  17 juin 2020, par Airat Galiullin

  I'll try to describe a situation :
I have Ubuntu server with installed ffmpeg and a streaming service that is creating HLS.

  



  That streaming service for generating HLS need RTMP stream which is generated by ffmpeg from local files in VOD on this server (files are mp4 format).

  



  I need to generate EPG on ffmpeg rtmp re-streaming step. Is it possible or may be other good solution for my situation ?

  



  RTSP generation SH :

  



  while true;
 do
  for file in $(ls -1);
   do
    ffmpeg -re -i "$file" -vcodec copy -bsf:v h264_mp4toannexb -acodec copy -f flv rtmp://localhost/path/for/channel
   done
