Google Tech Talk: Simple interactive 3D modeling for all – VideoTrace

3D models from basic video… This can be huge in all sorts of ways.  For exponential growth you need to go virtual.

  • This is a technology called VideoTrace from Australia
  • The Siggraph paper describing VideoTrace is available here (pdf 6MB)
  • Larger videos available here, with a more compressed version here.

haXe Video 1.0 Released


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

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!

Vector Wars Update: HD Video for Flash9 and Silverlight



Flash Performance and HD (H.264) Video Progress

Fast performance is needed for good video combined with interactivity especially. Quickly comparing AS2 to AS3 shows that AS3 and the AVM2 virtual machine in Flash9 is much faster. If you are combining Flash and video especially when it is time to go HD, you will need performance.

Compare AS2 to AS3 rendering: AS2 & AS3 Note the as2 item only has 10000 pixel operations, the as3 item has 50,000 and is considerably more usable, in fact the AS2 version isn’t usable since it is slow. [source] This is a good test because it checks the movement of every pixel on the screen which leads me to video performance.

Flash HD in the FLV format is pretty nice looking today in Flash9 with AS3. But to keep up there are more formats and a move to support H.264/MPEG-4 AVC I am sure for online TV/Movie market.

The reason to bring up performance and video is because the video battle on the web is heating up even more between Adobe and Microsoft with Flash Video and Silverlight Video. The recent released info regarding HD on Flash is to combat Silverlight HD video that is looking pretty good.

Silverlight Performance and HD Video VC-1

View this Halo 3 video in Silverlight HD:

Recently Silverlight came out last week officially on Wednesday, really the 1.0 release is just a video and javascript release but when you view the videos below you will see that they have a short coup de tat on Flash video at the moment in terms of HD quality video.

Silverlight also has been pushing TV on the internet. See these samples that are actual TV on web pages already using Silverlight.

  1. Home Shopping Network Online
  2. ET Emmy’s coverage
  3. They also have WWE and MLB.com baseball already using Silverlight video.
  4. Netflix online video uses Silverlight

Flash video is cool and you can do great fun things like neave.tv (flash 8) and high definition FLV video in flash9 with AS3 and on occasion AS2 if it is just video with full screen flash but when you are talking TV and movie quality, it is still up for grabs but both are looking good especially Silverlight and that Halo 3 video.

Flash video is updating to H.264

Tinic Uro reports the beta player of flash that has HD now. Currently the FLV format is the web leader (you tube, Google video) but is not as good quality as Silverlight until they update to H.264 at least in terms of standards video. This is probably 6 months off?

Video literally changed in the internet in the last two weeks with the Flash announcements and Silverlight launching. I am surprised at Silverlight’s adoption rate and partnerships so far with the 1.0 offering which lacks many programming tools, but I see why on the video front why they did it. When 1.1 comes out it has all the programmer toys, and it will attract a lot of attention I think. It is all about performance and HD video right now.

Yes yes… Quicktime has done HD/H.264 video for a while but Quicktime is just a video format really, it will be able to be used in the new flash video as well as other formats but it doesn’t have the interactive platform behind it like Flash and Silverlight have.

The difference is the choice of format and standards. Silverlight with VC-1 and Flash going to H.264 codec. They are largely competing standards that are both “HD”.

The good news is we have competition to bring really high quality video to the web, the mashups with HD video in interactive games, demos, advertising etc will be very fun.

Flash Determined to Continue to Lead In Video On the Web

Tinic Uro who works on the Flash player made some amazing announcements about the new beta flash player. Video is getting a major upgrade to the already pwning FLV format on the web, they are moving away from that however towards a H.264 standard format (can you say HD movies on your PC in Flash?). Silverlight (Windows Media VC-9), Quicktime and other formats were looking superior to FLV quality (although noone can beat the file size) but this has changed the game completely.

The people running the Flash product are just answering the calls of the market very effectively.

Some tidbits of what is possible with the new H.264 standard video in Flash:

  • Playing content of other formats inside of Flash without worrying about loading another player or plug-in. (MPEG player or Quicktime movies for instance)
  • Play HD video on your PC in Flash with support from video card manufacturers in the works.
  • Play AAC SBR data instead of MP3, 5.1 channel surround sound.
  • Use open source only tools for your complete video pipeline.

It seems Flash is determined to continue to lead video on the web
