Adobe to Publish and Open RTMP Specification (Real Time Messaging Protocol)

drawk — Wed, 21 Jan 2009 04:58:43 +0000

Adobe will essentially open up the RTMP protocol officially. RTMP has been used in other tools such as Red5 and haXe video for some time now. But officially having it open will make it possible for more products built on it. I am sure that most of this is to combat silverlight and to gain more video users that can play flash formats. RTMP spec will be posted here when ready.

RTMP provides an enhanced and efficient way to deliver rich content. Developers and companies will have free and open access to the documented RTMP specification to help enable unparalleled delivery of video, audio and data in the open AMF, SWF, FLV and F4V formats compatible with Adobe Flash Player.

Adobe has also been working on more real-time protocol tools based on UDP instead of TCP (which RTMP is based) that fall under RTMFP using ordered UDP that will be interesting to watch evolve. Stratus is so far a sample of what is to come there.The UDP based real-time tools will be able to beat the capabilities of TCP based real-time tools when using authoritative servers.

But with the RTMP announcement, multiuser and video applications should thrive even more with an open RTMP spec.

PyAMF 0.3 Released and Sample on Google App Engine

drawk — Thu, 17 Apr 2008 04:08:19 +0000

A great Action Message Format (AMF) remoting kit for server side for the pythonistas is pyAMF, they recently released PyAMF 0.3 and have a sample running up on Google App Engine. There is also a tutorial for getting PyAMF running on Google App Engine. Aral Balkan got this running as well.

Features of pyAMF currently:

AMF0 encoder/decoder for legacy Flash Players (version 6-8).
AMF3 encoder/decoder for the new AMF format in Flash Player 9.
Support for IExternalizable, ArrayCollection, ObjectProxy, ByteArray (with zlib support), RecordSet and RemoteObject
Remoting gateways for Twisted, Django, TurboGears2, Web2Py, Pylons and any compatible WSGI framework.
Authentication/setCredentials support
Remoting client using httplib with authentication support
Service Browser (DescribeService header) requests supported
Local Shared Object (LSO) support
Adapter Framework to integrate nicely with third-party Python projects

haXe Video 1.0 Released

drawk — Sun, 16 Dec 2007 03:09:49 +0000

haXe, one of the coolest and most versatile languages and platforms of today just released something to add to the already amazing feature set of haXe. Nicolas Cannasse has posted about releasing haXe Video 1.0. I have been engulfed by Red5 for a few weeks and this could not have come at a better time for fun.

haxeVideo is an opensource video streaming server entirely written in haXe.

Features of haXe Video 1.0:

FLV streaming using RTMP protocol
Webcam and Microphone recording to FLV file
Live streaming for web conferencing
light and fast scalable server
only 50 KB of server source code : modify whatever you need !

Sandy3D and Red5 Server Attack! – Sandy 3.0 Final Released for AS2 and AS3

drawk — Mon, 12 Nov 2007 18:32:20 +0000

Sandy 3.0 was released today. To go along with that a RedSandy (Red5 and sandy demo) has also been released. Sandy is the original 3d flash engine that was around before Papervision3D and Away3D and all the others. Sandy3d is an excellent library and it has many features that others do not have well particularly in the easier control of objects and importing all types of files such as ASE, WRL and 3ds in addition to COLLADA which other 3d engines like PV3d and Away3d support although it has been slower in the past 3.0 may change that.

Sandy 3D engine main features are :

Flash player 7 to 9 compatibility.
Both MTASC and Macromedia compilers compliant for AS2 and Flash CS3 and FlexBuilder for AS3 versions.
Several 3D primitives, allowing fast and parameterized object creation without any 3D modelisation knowledge.
Advanced and easy object management allowing some fantastic possibilities during your creations (scaling, rotation, translation, tween, etc.)
Advanced camera management ( rotation, motion on linear or bezier-curve path, movements, etc.)
Complex object loading thanks to the .ASE and .WRL files parser , but also Collada and 3DS files for AS3, (files generated by several 3D object modeling packages such as 3D Studio Max or Blender)
Material system to easily change your objects appearance. Several material are available allowing to create transparent faces, bitmap texture and video texture as webcam video stream.
Managment of Flash filters bringing some very nice visual effects

Red5 is the best multi-user media server out there right now and it is built with Java.

The cool and probably most interesting part is Sandy combined with Red5 to create multi-user environments in 3d for flash. There have been experiments with this and many attempts at this and is being done but an open source kit that does this is very helpful and these are two great flash toolkits in Sandy and Red5.

Get your game on!
