• Convert and stream videos [on hold]

  26 septembre 2013, par user969068

  I am going to develop a php script on linux based server which will be used to upload videos on server and stream to users. I have seen many open source free/paid libraries available with flash,html5 etc players. After research I have decided to go with ffmpeg to convert videos and use jwPlayer with RTMP protocol to stream videos.

  I am not much familiar with streaming concept but I have researched a lot on this subject since few days, so last I thought to ask here if I am going the correct way to achieve my goals, which are listed below :

  1. My main concern is to start streaming videos as soon page is loaded.
  2. Convert videos after upload ( Found ffmpeg for this purpose is well suited )
  3. Seeking video should be faster (which after searching I found is good with RTMP protocol)

  Please can someone guide me if I am going in the right direction by choosing ffmpeg, jwplayer with RTMP protocol. Thanks a lot for any guidance.
