• ffmpeg streaming through error

  16 janvier 2016, par user2201239

  I’m trying to stream to a streaming server with ffmpeg, its website is called http://livestreamcast.org. Everything works on FMLE, so I tried to copy the same configuration to ffmpeg, but everytime it gives me error.

  [rtmp @ 0x939e520] Unknown connect error (unsupported authentication method ?)
  [rtmp @ 0x939e520] Server error : Connection failed : Application rejected connection.
  rtmp ://live-cdn.livestreamcast.org/live/66f4a37bb72fc61cf5ca4c45bf4775c5 : Unknown error occurred

  ffmpeg -i "myhlsstream" -c:v libx264 -b:v 2500k -s 800x450 -c:a libmp3lame -b:a 20k -f flv "rtmp://live-cdn.livestreamcast.org/live/66f4a37bb72fc61cf5ca4c45bf4775c5"

  I tried many different configurations by changing bit rate, audio format, etc. but nothing works and getting same error every time.
  Or is it possible that the server reject the connects from ffpmeg encoder ? which is most probably unlikely !
  I tried to contact the website owner on skype, but got no reply and couldn’t find any support email, so I have no idea, how to make it work.

• Best Codec and Pixel Formats to use in FFMPEG Pipeline

  19 décembre 2022, par user20623229

  I have created an FFMPEG Pipeline to stream video frames to an RTSP server. The frames are RGB frames with 3 dimensions. My pipeline command is as follows :

  


  openPipeLine = _popen("ffmpeg -f rawvideo -r 30 -video_size 720x1280 -pixel_format bgr24 -i pipe: -vcodec libx264 -crf 24 -pix_fmt yuv420p -f rtsp rtsp://localHost:8554/mystream", "w");


  


  I can barely make out the picture when I connect to the server via VLC Media. The colors seem scrambled. I've attached a sample image and the output on the server.

  


  Are there any recommended Codec's that I can use to solve this ? Perhaps the pixel format should be changed. I'm currently using a Codec and pixel format that I found online without knowing if these are the best options.

  Thank you very much.

  


• Nginx RTMP module to generate HLS

  28 novembre 2020, par Joe Lin

  I'm streaming an audio stream with opus codec from Kurento
via ffmpeg to nginx-rtmp-module. I'm using the below command to stream to nginx-rtmp :

  


  ffmpeg -protocol_whitelist file,udp,rtp  -i test-audio.sdp  
-c:a libopus  -f opus rtmp:///live/


  


  I see no error on the ffmpeg side. But there's no m3u8 file being generated. But I noticed the following in the nginx log :

  


  2020/11/23 23:19:31 [info] 95#0: *8 connect: app='live' args='' flashver='FMLE/3.0 (compatible; Lavf57.83' swf_url='' tc_url='rtmp://192.168.4.28:1935/live' page_url='' acodecs=0 vcodecs=0 object_encoding=0, client: 172.17.0.1, server: 0.0.0.0:1935


  


  Noticed the acodes=0. Does this mean that it doesn't like opus codec ?

  


  Below is my nginx.conf :

  


  rtmp {
    server {
        listen 1935;
        chunk_size 4096;
        application hopefm {
            live on;
            interleave on;

            hls on;
            hls_path /mnt/hls;
            hls_fragment 3;
            hls_playlist_length 60;
        }
    }
}


  


  Thanks for any help.
