• avformat/rtsp : Send mode=record instead of mode=receive in Transport header

  15 janvier 2024, par Paul Orlyk

  avformat/rtsp : Send mode=record instead of mode=receive in Transport header
  Fixes server compatibility issues with rtspclientsink GStreamer plugin.
  >From specification :
  
  RFC 7826 "Real-Time Streaming Protocol Version 2.0" (https://datatracker.ietf.org/doc/html/rfc7826), section 18.54 :
  
     mode : The mode parameter indicates the methods to be supported for
  
           this session.  The currently defined valid value is "PLAY".  If
  
           not provided, the default is "PLAY".  The "RECORD" value was
  
           defined in RFC 2326 ; in this specification, it is unspecified
  
           but reserved.  RECORD and other values may be specified in the
  
           future.
  
  RFC 2326 "Real Time Streaming Protocol (RTSP)" (https://datatracker.ietf.org/doc/html/rfc2326), section 12.39 :
  
     mode :
  
            The mode parameter indicates the methods to be supported for
  
            this session. Valid values are PLAY and RECORD. If not
  
            provided, the default is PLAY.
  mode=receive was always like this, from the initial commit 'a8ad6ffa rtsp : Add listen mode'.
  For comparison, Wowza was used to push RTSP stream to. Both GStreamer and FFmpeg had no issues.
  
  Here is the capture of Wowza responding to SETUP request :

• VideoJS for HLS streaming not working on iOS

  13 février 2024, par Aames

  I have a website where I stream audio using HLS (m3u8 playlist + ts files).
I use VideoJS 8.3.0 to handle the stream in the frontend side.
The streaming works in all devices (PC, Android, Mac) except in iOS where it works intermittently and often it blocks.

  


  Here is my videojs initialization :

  


  player = videojs('stream-id', {
            controls: false, autoplay: true, preload: 'auto',
            html5: {
               vhs: {overrideNative: false},
               nativeAudioTracks: true
           }
        });

...

player.src({ type: 'application/x-mpegURL', src: 'https://.../master.m3u8' });



  


  And these are the headers of the m3u8 file :

  


  #EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:10
#EXT-X-PROGRAM-DATE-TIME:2024-02-13T09:00:00Z
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-DISCONTINUITY
#EXTINF:10.007800,
master0.ts
#EXTINF:7.214989,
master1.ts
....


  


  I use ffmpeg to create the playlist from mp3 files :

  


  ffmpeg -i inputFileName -c:a aac -b:a 128k -ac 2 -f hls -hls_time 10 -preset ultrafast -map 0:a -flags -global_header -hls_list_size 0 -hls_flags append_list outputFileName



  


  Am I doing something wrong ? Any help would be appreciated
Thanks

  


  I tried this solution : Videojs HLS m3u8 files are not playing in iOS devices and safari browser but it does not work for me
