• HTTP Live streaming iOS not refreshing the index .m3u8 file

  27 février 2013, par Emerson Fittipaldi

  I searched all similar questions on StackOverflow, but found none to answer my problem.

  I am trying to stream some movies from my Linux computer (openSuSE 12.1) to my iPad. I convert them with ffmpeg, segment them with my own segmenter, place them in the www folder of my apache2 server and also place inside the .m3u8 playlist. Til here - all is ok !

  I start playing the movie (HTML page with tag) and it plays nicely, but only the first five segments, which have been loaded with the first load of the playlist. The HTML page (the browser, or the player - no idea) does not refresh (re-download) the playlist from the server. Here is what my .m3u8 playlist file looks like :

  #EXTM3U
  
  #EXT-X-MEDIA-SEQUENCE:19
  
  #EXT-X-TARGETDURATION:8
  
  
  
  #EXTINF:8,
  
  http://192.168.1.4/segment_19.ts
  
  #EXTINF:8,
  
  http://192.168.1.4/segment_20.ts
  
  #EXTINF:8,
  
  http://192.168.1.4/segment_21.ts
  
  #EXTINF:8,
  
  http://192.168.1.4/segment_22.ts
  
  #EXTINF:8,
  
  http://192.168.1.4/segment_23.ts

  Segments are in the same folder as the playlist file, segments are correctly encoded (because I can see at least the first five ones :D). I also watch the access_log from the apache server and I see the first load of the playlist, then the consequent load of all 5 segments and it stops till there. It doesn't even try to further refresh the m3u8 file.

  If it matters - iOS 5.0, iPad 2, Wi-Fi version only, not jailbroken

  Ideas ? What am I doing wrong ?

• Live Video Chat for iPhone and HTTP Live Streaming

  2 novembre 2014, par mayuur

  So generally, I want to make an app which has video chat functionality for iPhone. But after many searches, I am still not able to find any successful results. Is there any public or even for that matter, private API available for doing this on iPhone ??? If you have an YES answer, please help me.

  Basically, what I want is to read the streams of the video on both the devices connected for chatting. Thanks a lot in advance and please help me if you can.

  p.s - I have already checked iDoubs but it failed and always shows some unknown problem and for that reason, doesn’t allow me to connect to anyone.

  ALSO : The suggested method I have found is via HTTP Live Streaming. But, in that too, I have multiple doubts.

  1.) I need to find how do I upload my video from iPhone to the HTTP server from where I would be broadcasting ?

  2.) Can you please post something related to setting up the server ? How do I feed the video to the FFMPEG Server ?

  Mainly, I need to find the upload method. I am right now simply sending hex-code in the form of NSDATA to the server and I am stuck there. The main problem is, It is live. How do I handle that ?

  It would be best, if you could help me make the iDoubs work properly.

  Thank you so much for any kind of support !

• transcode segment files without stutter for http live streaming

  28 juillet 2015, par zerocap

  I segmented a multicast video stream into small ts files for my HTTP live streaming service and it worked quite well. Then I found the bitrate of the source was too high (1.5mbps) so I set up a background job to transcode the ts files to a smaller bitrate (500kbps) using FFmpeg. The problem is that the 500k .m3u8 playback stutters(on every new file’s loading) and is not as smooth as the 1.5mbps one.

  My transcoding command line is like following :

  ffmpeg -i /home/rca/tst.ts -f mpegts -acodec libmp3lame -ar 48000 -ab 64k -vcodec libx264 -b 500k /home/rca/tst.ts

  Any ideas for this ? Thank you !
