Managed DirectX AudioVideoPlayBack Problems

Hi,

Im using DirectX.AudioVideoPlayback.dll in my C# project to play both audio and video. But some problems are facing.

1. Video.Dispose() or Audio.Dispose() methods are not working correctly. Even I disposed the video object used it is not freeing all resources used. I tried to delete the file that is used by the video object to play video after disposing it. But windows shows that 'File is already in use'. It only freeing resource after closing the application. This is a major Issue.

2. Video.Ending event is not firing always.

Any help will be appreciated. Thanks in advance

Actually, I've just found a workaround: After each volume adjustment you make, do this: video.Ending += new EventHandler(audio_Ending); video.Audio.Ending += new EventHandler(audio_Ending); // This seems to kill the bug ! Nice... And I was about to write my own wrapper... I might still do so...

There is a bug in the "Video" class that makes it not to invoke the "Ending" event handler when you change the volume of the Video object. I've sent this bug report at MS DX team a few years (?) ago but it seems that it's still in there...

The 1st is weird, but it may be caused by the 2nd...

I hope this helps.

Are you testing the same video?

Hi,

That is not the case. No other application is using that resource. If that is the case why video ending event not fires. Certainly this is the problem with Microsoft.DirectX.AudioVideoPlayBack. I have no problem facing while using directShow

Thanks

You have to check whether other dependencies to the file are still existing. because certinly that there is another thread or process is using this ressource
