• Imagick refresh

  25 septembre 2013, par Mikko Koppanen — Imagick

  After some hiatus I’ve been getting back on fixing bugs on Imagick and getting the code into more representable condition. This hiatus has been a result of busy work schedule and getting a new start-up running in Kuala Lumpur.

  While fixing a bug related to clone keyword I came across the following resource : http://www.rubblewebs.co.uk/imagick/. The page contains quite a nice collection of Imagick operations and is definitely worth checking out.

  On the other news, the development has been moved to Github. As I’ve been the most active developer of Imagick in the past years I decided to move the code to Github where rest of my projects are located : https://github.com/mkoppanen/imagick. For the past few days there has been quite a lot of development, mainly working on removing the excessive use of macros in the code to make things more readable and debuggable. This might be a good place to give thanks to Remi for fixing quite a lot of compile warnings and raising bugs regarding Fedora Packaging Policy. Most likely there will be a couple of beta releases in the near future.

  As mentioned in the previous post Windows builds are now available via http://windows.php.net and my builds provided here should be considered obsolete.

• 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.
