• Insert discontinuous ad video at the center of a HLS playlist

  25 juin 2020, par A-Circle Zhang

  I'm trying to use "EXT-X-DISCONTINUITY" tag to add ad video at the center of another HLS video,

  


  It should be very easy if it is added to the beginning/end of the video, just like :

  


  #EXTM3U
#EXT-X-TARGETDURATION:10
#EXT-X-VERSION:4
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-PLAYLIST-TYPE:VOD
#EXTINF:10.0,
ad001.ts
#EXTINF:8.0,
ad002.ts
#EXT-X-DISCONTINUITY
#EXTINF:10.0,
movie001.ts
#EXTINF:10.0,
movie002.ts
...


  


  But now I'm trying to add to the center of the video, like :

  


  #EXTM3U
#EXT-X-TARGETDURATION:10
#EXT-X-VERSION:4
#EXT-X-MEDIA-SEQUENCE:0
#EXTINF:10.0,
movie001.ts
#EXTINF:10.0,
movie002.ts
#EXT-X-DISCONTINUITY

#EXTINF:10.0,
ad001.ts
#EXTINF:8.0,
ad002.ts
#EXT-X-DISCONTINUITY

#EXTINF:10.0,
movie003.ts
#EXTINF:10.0,
movie004.ts
...


  


  The gap between movie002.ts and ad001.ts, plays very smoothly, that's ok,

  


  but the the gap between ad002.ts and movie003.ts, will get stuck, or directly fast forward and missing 2 3 seconds of video.

  


  So, is there any solution to this without retranscoing whole video ? Thank you...

  


  Edit : I found Hls.js support this very well in web browsers, but native player of some mobile browsers (like samsung internet), some desktop player (like PotPlayer) have this problem.

  


• 3 seconds latency while streaming with Wowza Server

  18 mai 2015, par kaizen_labs

  I’m trying to develop a live streaming application with RTSP protocol.

  On the PC with the Wowza Server, I execute the following command :

  Code :

  ffmpeg -f dshow -i video="Name_Of_My_Cam":audio="Name_Of_My_Microphone" -vcodec
  
  h263p -f rtsp -muxdelay 0.1 rtsp://:1935/live/test

  And I’m trying to play this stream on a VideoView on my Samsung Galaxy Note 3 Lite. Here is the code :

  @Override
  
  protected void onCreate(Bundle savedInstanceState) {
  
      super.onCreate(savedInstanceState);
  
      setContentView(R.layout.activity_main);
  
  
  
      VideoView vv = (VideoView) findViewById(R.id.videoView);
  
      // Receive RTSP video from Wowza Server
  
      vv.setVideoURI(Uri.parse("rtsp://:1935/live/test"));
  
      vv.requestFocus();
  
      vv.start();
  
  }

  I managed to read the video and the sound but it makes 3 secondes (or more...) to start and I keep this delay during all the streaming. It is very annoying because I want to develop a call session.

  Does anybody know how to reduce this delay ? Is it a Wowza issue ?
