• 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.

  libavcodec : Implementation of AAC_fixed_decoder (LC-module) [4/4]
  Build system modified
  There are several warnings occurring during build after this patch is
  
  applied. The cause of most of these warnings is in that some definitions
  
  needed here are logical part of sbr module and are added in later patches.
  
  When this patches are applied these warnings stop occurring.
  The only warning that is added here and is not fixed with later patches
  
  is warning that warns that type mismatch for table ff_aac_eld_window_480.
  The reason for this warning is in that ER AAC ELD 480 is not integrated in
  
  to the fixed point implementation at this moment and there is no fixed point
  
  version of this table.

• Is there a way to stop ffmpeg from combining mp4s at max mp4 size ?

  3 janvier 2023, par Dray

  I am merging 64 gigs of mp4s together, though ffmpeg will go past the file size limit and corrupt it. Is there a way to stop ffmpeg at a 100 hour mark and create another file, resume, then repeat until finished ?

  


  This is my python code, with the ffmpeg code I used to generate the mp4. It works fine with less files/

  


  
from moviepy.editor import *
import os
from natsort import natsorted

L = []
total = 0
for root, dirs, files in os.walk("F:\door"):
    #files.sort()
    files = natsorted(files)
    with open("list.txt", "a") as filer:
            for file in files:
                if os.path.splitext(file)[1] == '.mp4':
                    filePath = os.path.join(root, file)
                    head, tail = os.path.split(filePath)
                    filePath = "file '" + str(tail)+"'\n"
                    print(filePath)
                    filer.write(filePath)
                    
                    #run in cmd: ffmpeg -f concat -i list.txt -c copy output.mp4
