• How to make HLS start from the begining

  15 juillet 2016, par Ariel Argañaraz

  I need some help with HLS streaming, I’m trying to create a playlist for streaming,

  I’m using ffmpeg to generate the files and the .m3u8 files. And for playing i’m using a web page with videojs player

  The idea is to simulate a live streaming using files already created.

  The problem is that in some version of iphone works and in another does not work.
  The problem is that when I start play the video in the Safari browser of my phone it freezes for a while and then download and play the last segment.

  for example if the video is split in 4 differents .ts files.
  It starts playing from the 4th .ts file and then stop.

  The problem is that I have 2 iphone mobile phone, one of them works perfectly but the other one not

  The not working cell phone is a iphone 6 (version 9.2.1)

  Here is my m3u8 file. Note that I’m using the #EXT-X-PLAYLIST-TYPE:EVENT and I remove the #EXT-X-ENDLIST from the botton. So it should be played as an live streaming.

  It works for another phones, it begins from the 0 second when I set the #EXT-X-START:TIME-OFFSET=0

  but in this version (9.2.1) the video freezes and then jumps to the last segment (webinar-3.ts) plays that segment and finally stop.

  #EXTM3U
  
  #EXT-X-VERSION:4
  
  #EXT-X-MEDIA-SEQUENCE:0
  
  #EXT-X-ALLOW-CACHE:NO
  
  #EXT-X-PLAYLIST-TYPE:EVENT
  
  #EXT-X-START:TIME-OFFSET=0
  
  #EXT-X-TARGETDURATION:6
  
  #EXTINF:5.046444,
  
  webinar-0.ts
  
  #EXTINF:5,
  
  webinar-1.ts
  
  #EXTINF:5,
  
  webinar-2.ts
  
  #EXTINF:5,
  
  webinar-3.ts

  Have anybody got an idea of what i’m doing wrong or how to get a m3u8 config that works for this iphone version ?

• My (FFMPEG issue ) RTMP server(freebsd) wont let me hear video when I play a huge file over the server itself :/

  19 avril 2021, par Engi Gang

  Hey my name is Alisha from Norway im trying to get my RTMP server working the thing is that it works just fine but I just cant stream over it with ffmpeg I can stream to it on OBS and it works fine, but I am trying to a website where people could watch old public domain movies from the 1950 some of the films are actually pretty big lol.... anyways I detailed bellow more

  


  rm -rf /mnt/hls/loool && ffmpeg -re -i "$file" -c:v libx264 -c:a aac -b:v 300k -b:a 95k -f flv -flvflags no_duration_filesize rtmp ://lambright.xyz:1935/live/loool

  


  any work around I literally cant play the audio :( I can only hear (my source file is an MKV and 3gb )

  


  Note I had a smaller mp4 file and it did played the audio, the video isnt even playable in chrome but on VLC it is, but only a small file worked fine... its fine when I stream from my pc, but whats the point I am trying to set up my vintage 1950 serverbox :') trying to build a nice website where users could watch neat and decent old movies that are public domain if you wonder :/

  


  Another note when I am trying to play it on my iphone safari browser it does actually play parts but audio is super corrupted like you hear the audio sometimes :((

  


  rtmp {
    server {
        listen 1935; # Listen on standard RTMP port
        chunk_size 4000;

        application live {
            allow play all;
            live on;
            record off;
            hls on;
            hls_nested on;
            hls_path /mnt/hls/;
            hls_fragment 2s;
        }
        
    }
}


  


• asp.net core live mp4 streaming

  8 octobre 2020, par kdma

  Prologue :

  


  I have a hikvision ipcamera that streams raw h264 from a rtsp :// url, I need to play this live feed in the browser.

  


  I managed to get a basic RTSP->ffmpeg-> (faststart) mp4 pipeline working and I can play the video when saved to a file.

  


  I don't understand how to make my controller action "streamable".

  


  I've tried various approaches like writing to Response.Body, Transfer-Encoding : chunked but nothing seems to work.
Here is the basic code :

  


  public IActionResult Play5(){    
      var ms = new MemoryStream();
      var muxer = new RTSPToMp4(ms);
      Task.Run(() => muxer.Stream());
      return new FileStreamResult(ms, "video/mp4");
}


  


  The memory stream contains the live feed but the response is empty here is the request\response from chrome :
