• 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.

• How to start live streaming on Mac using FFMPEG ?

  3 août 2014, par Alexandra Chis

  I am working on a MAC OS X Lion 10.7.5.

  How to properly install FFMPEG ?

  What I did :

  ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"
  
  brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-frei0r --with-libass --with-libvo-aacenc --with-libvorbis --with-libvpx --with-opencore-amr --with-openjpeg --with-opus --with-rtmpdump --with-schroedinger --with-speex --with-theora --with-tools

  and even (I think this should work, but it doesn’t)

  brew install ffmpeg

  Nothing works...I can’t list the inputs, I can’t start the streaming from the USB camera, I can’t do anything.

  ffmpeg -f video4linux2 -s 320x240 -i video="USB cam":audio="USB mic" -f oss -acodec libvorbis -vcodec libvpx -f webm http://localhost:1234/streaming

  The errors I get look like this :

  unknown input format 'video4linux'

  and the same happens for alsa, openal, vfwcap etc.

  So did anyone try live streaming with FFMPEG from MAC ?
  How to install FFMPEG so that is supports video4linux2 or v4l2 or any input format at all ? How to list the devices (USB webcams or integrated webcams) ?

• rtmpproto : Pass the ’live’ parameter in the right unit

  3 octobre 2013, par Martin Storsjö

  rtmpproto : Pass the ’live’ parameter in the right unit
  The current magic numbers passed are values in seconds, while the
  
  parameter itself should be passed over the wire in milliseconds.
  This makes (some/all ?) live streams from Red5 work correctly, that
  
  previously returned StreamNotFound even with "-rtmp_live live". After
  
  this commit, the default ’any’ also works on these streams.
