[Pharo-project] video in Pharo
Hi, Is it possible to play a video in Pharo ? How ? I'm thinking about writing a Pharo interface to Pharocasts, maybe integrated to ProfStef. It can be funny. Laurent
there was a mpeg plugin in squeak but I do not know its status. Stef On Jan 28, 2010, at 10:02 PM, laurent laffont wrote:

true I remember the point made by david about the effort required by the port. Stef On Jan 28, 2010, at 10:54 PM, John M McIntosh wrote:

And what do you want with an old mpeg decoder anyway? The world moved on the last 10 years... Marcus

Take the video/audio player classes from Sophie, that will give you at the high end quicktime audio/video on mac/pc.. Degrading down to mpeg or ogg on mac/windows/linux On 2010-01-28, at 1:02 PM, laurent laffont wrote:

I remember about the development of a Gstreamer plugin in 2008. Don't know its status now. Hilaire laurent laffont a écrit :

I did the GStreamer plugin for Etoys ala OLPC The problem is you can't install the GStreamer software on a mac in a user friendly manner. Having to drop to the terminal session, install MacPorts by doing sudo ports install gstreamer just won't cut it. Reusing the audio/video framework we did for Sophie would be a far better thing. It has a set of abstract classes to deal with audio, video, audio/video. Concrete classes then provide the ability to play media from a set point, with controls to play/stop/rewind. Audio uses the Squeak sound system and various decoders, video would work it's way thru quicktime, mpegplayer, oggplayer. You just fed it a URL, and cmds, like play...

Just curious as I don't have time now to look deeply on that: Is it available as an external package one can load in a Pharo image? Does it requiere VM magics? Hilaire

Well I'm not sure what you are asking for. The Gstreamer stuff starts at: MCHttpRepository location: 'http://www.squeaksource.com/GStreamer' user: '' password: '' You need a plugin and the GStreamer underpinnings install in your operating system. If you have have a linux box that is easy. If you have a mac, you could use MacPorts to install GStreamer and I could give you a plugin I built for test purposes. As for the Sophie stuff, well it uses FFI for talking to Quicktime, there is an optional quicktime plugin but all that is used for is to let quicktime tell us when it has rendered a frame into a squeak surface so we can signal a squeak semaphore to draw the surface to the Display. The fall back is to do a fixed frame rate drawing cycle, which is what happens on Windows. The Sophie player of course uses Tweak as a reference base, but could be converted to some other UI framework. =========================================================================== John M.
