• Set up a Red5 server with FFmpeg for live streaming to iOS

  13 mars 2013, par Giancarlo Molina

  I'm an app developer and I need to implement FFmpeg to transcode/change an rtmp live stream to an http live stream so that I can play it on any iOS device (iPhone and iPad).

  My problem is that I am fairly new when it comes to server, media stuff and FFmpeg. And I need to change the server so that I can transcode the live stream on the server side (which I have read that is possible). Any tips, suggestions, sample code, or tutorials would be of great help.

• HTTP Live Streaming MPEG TS segment

  23 janvier 2012, par user1069624

  I'm using FFMPEG and a free segmenter (Carson Mcdonald's) to produce my ts segments which i later save to a web server and play with Quicktime by playing the .m3u8

  If I have segments 1,2,3,4 and another stream with segments 1,2,3,4 and would like to interleave them what should I do. If i do as follows : 1,2, other stream's 3, 4 It works fine. However, If i want to do as follows : 1,2, other stream's 4, 4 it doesn't work.

  In other words the segment to be added must have the same number as the one I'm replacing. Why is that ? Does it have to do with PCR ? I would like to be able to interleave any segment anywhere.. How can I do that ?

  Thank you,

  The M3U8 file is

  #EXTM3U 
  
  #EXT-X-TARGETDURATION:10 
  
  #EXT-X-MEDIA-SEQUENCE:21 
  
  #EXTINF:10, sample_ep_386k-00021.ts 
  
  #EXTINF:10, media_2.ts 
  
  #EXTINF:10, sample_ep_386k-00023.ts

• How to implement HTTP Live Streaming server on Unix ?

  5 septembre 2012, par alex

  I just realized that Apple required HTTP Live Streaming in order to view videos in iPhone apps. I was not aware of this before... I am now trying to understand what this involves so I can decide whether I want to do the work and make the videos available in 3G or limit video playing to users who are connected to wi-fi.

  I read the overview provided by Apple, and now understand that my server needs to segment and index my media files. I also understand that I don't have to host the content to be able to stream it (I can point to a video hosted somewhere else, right ?).

  What's not clear to me at this point is what to implement on my server (Ubuntu Hardy) to do the actual segmenting and indexing on the fly (once again, I do not host the videos I want to serve).

  I found a link explaining how to install FFmpeg and X264, but I don't know if this is the best solution (since I have an Ubuntu server, I can't use the Apple Live Streaming tools, is it correct ?). Also, I do not understand at which point my server knows that a video needs to be converted and starts the job...

  Any feedback that could help me understand exactly what to do on the server side to be able to stream videos on my iPhone app in 3G would be greatly appreciated ! (Oh, and just it makes any difference, my app back-end is in Rails)
