• A few questions about running a video gallery site

  30 septembre 2013, par Kevin Kevinz

  my site is going to be hosting a lot of videos. I'm using FFMPEG for all video functions. My current video upload plan is as follows :

  -get input video
   make video thumbnail
   if its mp4/flv, convert it to ogv (for opera support)
   if its not mp4/flv, convert it to mp4 and also convert the original to ogv

  (the file conversions are running in the background)

  I'm using jwPlayer 6 for all videos currently. What can I do to maximize cross-browser and cross-platform support ? iOS won't run flv because it can't run flash, so is it worth it to just convert every file to MP4 ? And what about HTML5 video ? Should I consider HTML5 as my primary player and jwPlayer my fallback ?

  Thanks everyone.

• PHP extension writing

  19 octobre 2013, par Mikko Koppanen — Imagick

  I’ve written quite a few PHP extensions over the past years and thought that I could share some of the experience with larger community. PHP internals can be a bit scary at times and in the past I’ve scoured through a lot of extensions to find practical examples of things such as how to return objects from internal functions/methods, how to handle different types of parameters, class properties etc.

  To document some of the experiences I started a project called extsample, in which I plan to add practical examples related to extension writing. There won’t be extensive written documentation outside the code, but hopefully the code itself contains enough nuggets of information to be useful. As the README says, if you need a specific example or clarification on something just open an issue in Github.

  The project is still very fresh but hopefully soon it will contain more examples. Pull requests are also welcome if you have code that you want to share with others.

• How to compile FFProbe as stand-alone application ? (Mac/Linux/Win)

  16 janvier 2016, par Hanzaplastique

  I’m trying to compile FFMPEG (I’m actually only looking for FFProbe, which is included in the FFMPEG tools) as a standalone application for MacOS X, Linux and possibly Windows.
  With standalone I mean that the libraries (x264, OpenJPEG, etc) are "embedded" into the executable so that I have to distribute only one executable for FFProbe - I apologize that I don’t know the proper lingo for this (please let me know), I’m a newbie when it comes to this.

  I have started by trying to do this under MacOS X, without any luck, but plan to do this for Linux and MacOS X as well.

  I did see a few pre-compiled binaries that do this, and do not depend on extra libraries, but the versions I have found so far are either not the current version (1.x) or do not included the libraries in the executable (evermeet).

  I followed several guides (for example : FFMpeg MacOSX Compilation Guide, reneVolution), with or without the use of Brew, but none of these show me how to embed the libraries in the executable.
  I assume this is an option to be set for linking.

  I’m not sure if it’s appropriate to ask this question for Win, Mac and Linux at the same time - if it’s not appropriate : I’d like to start with doing this for the Mac version.

  My system runs MacOS X 10.9, XCode 5.0.2, with commandline tools and brew installed. I’m only looking for an Intel binary, so not a universal or PowerPC binary.

  For Windows I can use either Windows 8.1 or XP, for Linux I currently use Ubuntu 12, all of which are virtual machines.
