• Raspberry / Nginx RTMP video streaming player

  28 mai 2016, par Emmanuel Brunet

  I’ve set up a Nginx RTMP server that receives a flv stream from a raspberry cam using raspivid and avconv (ffmpeg)

  on the pi side I run

  /opt/vc/bin/raspivid -n -fl -mm matrix -w 800 -h 600 -fps 25 -g 80 -t 0 -b 6000000 -o - | avconv -re -i - -nostats -c copy -f flv rtmp://mercure/cam/live

  note : the target host is called mercure

  the Nginx rtmp module on mercure is set like bellow

  rtmp {
  
      server {
  
          listen 1935;
  
          # chunk_size 8192; # This might positively affect CPU load
  
          chunk_size 4096;
  
  
  
          application cam {
  
  
  
                  # max_connections 100;
  
                  live on;
  
                  # meta copy;
  
                  allow play all;
  
  
  
                  record all;
  
                  record_path /var/CCTV;
  
                  record_interval 1800s;
  
                  record_suffix -%Y-%m-%d-%T.flv;
  
  
  
                  hls on;
  
                  # hls_nested on;
  
                  hls_path /tmp/HLS;
  
          }
  
  }

  in the http section I’ve defined a hls location

      location /hls {
  
  
  
              root /tmp/HLS;
  
              types {
  
                      video/MP2T ts;
  
                      application/vnd.apple.mpegurl m3u8;
  
              }
  
      }

  when I run

  ffplay rtmp://mercure/cam/live

  it works like a charm but I can’t get it working with Vlc using the same url.

  Any idea ?

  otherwise I’m also trying to install a javascript rtmp / hls video player does anybody succeed or experienced using an open source component like flowplayer ? I’ve read a lot of doc about that but each time installs fail or some components are missing.

  please help me getting this stream available thru a web broser. thanks in advance

  nginx version : nginx/1.12.2

  I’m trying to below.
  -> nginx -> ffmpeg multi encode -> HLS publish

  nginx configration is below (nginx.conf)

  ls2/${1}_mid -b:v 1024k -c:a aac -ar 44100 -ac 2 -r 30 -f flv rtmp://localhost/h
  
  ls2/${1}_high

  But it can’t work. The access.log appears just one line.

  192.168.1.121 [02/May/2018:21:52:39 +0900] PUBLISH "hls" "test2" "" - 580840 753 "" "FMLE/3.0 (compatible; Lavf57.55" (21s)

  There is no "hls2" PUBLISH on access log.

  When I tried to run the ffmpeg command line while nginx is running, it was succeed.

  Why ffmpeg called by nginx doesn’t work ? If you have any solution, let me know.

  Bests,

• Traceback error with Python when using ffmpeg to convert a video

  16 mai 2013, par TheMickeyNick

  The simple way my script runs is the user provides a folder location and a filetype and glob.glob() finds the files with the filetype provided and adds them to a list. It then uses a for loop and goes through the list and converts each video. But it doesn't like when I try to run my ffmpeg command. Any help would be awesome. I'm also using Win 7 64 bit with 64 bit ffmpeg and Python 3.3
  Here's the error :

  I've looked around and most of the tutorials are in 2.7 the code is 3.3 and I can't find a tutorial to use ffmpeg for 3.3. My ffmpeg is set to 'ffmpeg64' on my PATH.

  Thanks !
