HowTo: Upgrade Kinect Audio Positioning code from older Beta SDK
24 Οκτωβρίου 15 09:02 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

Exploring the Kinect SDK v1.8 Developer Toolkit Browser application, I noticed some audio positioning visualizations at various samples (specifically at Audio Basics, Audio Explorer and Kinect Explorer samples), but I kept on looking for some simpler/cleaner sample code to return audio positioning info that would be easier to reuse. So I can across http://kinectaudioposition.codeplex.com that […]

Gotcha: MediaElement Source=null releases stream, SetSource(null) fails

This is my contribution to: http://stackoverflow.com/questions/19294258/forcing-mediaelement-to-release-stream-after-playback/27436323 If you use MediaElement, make sure you don’t get bitten by this one: http://msdn.microsoft.com/en-us/library/cc626563(v=vs.95).aspx ArgumentNullException – The mediaStreamSource is null. … After calling this method, MediaElement.Source returns null. If this is called and MediaElement.Source is set, the last operation wins. If a MediaElement is removed from the UI tree […]

My comment at: https://github.com/loarabia/ManagedMediaHelpers/issues/16 While trying to use Mp3MediaSource at ClipFlair Studio’s AudioRecorder control (http://clipflair.codeplex.com), I noticed that when I was doing Stop() at MediaElement and then Play() it kept on playing from where it was before at Mp3MediaStreamSource So I did the following fix:   1) added these fields /// <summary> /// The first […]

Fix: Silverlight Media Framework Player VolumeElement out of sync
11 Φεβρουαρίου 13 06:54 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

I was just adding a storable (persistent) Volume property to the MediaPlayerView class used at ClipFlair’s MediaPlayerWindow (connected to the underlying SMF player’s VolumeLevel property), when I realized that after reloading saved state, the SMF player’s Volume control would show a different value than the value set to it (which I could confirm by flipping [...]

HowTo: Hide Video area of Silverlight Media Framework Player
03 Οκτωβρίου 12 12:25 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

Since our onoing project ClipFlair is a follow-up of the succesful project LeViS, during its development I’m also looking at covering possible use-cases I infer from feedback entries at LvS application issue tracker on Codeplex (note that ClipFlair is also opensourced on Codeplex at http://ClipFlair.codeplex.com). One such issue (http://lvs.codeplex.com/workitem/11511) was titled “Allow video hiding while [...]

HowTo: Compress speech audio using CSpeex codec at Silverlight apps
04 Αυγούστου 12 07:15 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

Following up on my post on how to fix CSpeex (http://cspeex.codeplex.com) to compile at Silverlight 5 (see http://zoomicon.wordpress.com/2012/06/09/fix-compile-cspeex-audio-codec-at-silverlight-4-rc-and-silverlight-5/).  Initially I thought it was not working correctly, but then I noticed I was running it on Terminal Server and didn’t have an audio device available. Running SLAudioDemo included in the CSpeex distribution (after doing the fix [...]
