Using The DirectX 11 SDK, Load A Video (with Sound) And Play It?
Nov 2, 2010
I am having problems locating any documentation or examples for rendering video on a form using DirectX. I need to use DirectX because I will be putting overlay's on the video loaded dynamically. I will also want to perform transitions between 2 video instances.
I can not find any documentation on Google or Microsoft's site, Such as render the video on a 3d object as a texture, maybe... IDK?
This is for Visual Studio 2010, .net framework 4.0, using vb.net.

I have a WPF 4/VB.net project, and I'm trying to play video in it. I've been using a mediaelement, much to the chagrin of the program's overall performance. Thus, I'm looking into the only other viable alternative that I can find for my project...directx.
Which brings me to my question. Is it possible to play video (either Theora [.ogv] or Flash Video [.flv]) in DirectX?

Hey guys, I'm a new guy in VB.NET. I am proposing my final year project a title called music studio. My version of music studio is like real music video where we can play many sound at any time. For example, the application that I want to build can create many button and also add an audio along with it. And then, when we hit the 1st button, it play 1st audio. while 1st audio play, we also can hit 2nd button and 2nd audio is playing. for example, 1st audio is sound of man walking, and then 2nd audio is the sound of glass break. lastly 3rd sound sound of police siren play. Is it cool? so, my question is, is it possible the I can build an application by using VB.NET?

I have background sound loop with the My.Computer.Audio and it works fine. I want to play another sound (like a beep) when desired without stopping the background sound. Several examples I have found don't seem to work. I am in VB.NET 2008 Professional.

I was wondering if it was possible to have a program open Firefox, and have it open a bunch of tabs that all go to a link with a video, and then have it automatically play that video?

I am trying to build a small program which will allow some one to click on the exit button and the sound will play and at the end of the sound the program will then close. The sound clip is about 3 seconds long Here is what I have:
Imports Microsoft.DirectX
Imports Microsoft.DirectX.DirectSound
Public Class Form1
Private Dsound As CSoundDevice

I have scoured just about every code sample on the web, and am still having trouble. Basically my code follows the following structure:
I installed the DirectX SDK, and imported AudioVideoPlayback Imports Microsoft.Directx.AudioVideoPlayback '''
Then I create my VideoPlayer Public WithEvents VideoPlayer as Video So far so good, I have event handlers and a video object
Then:
[CODE]...........
I execute the above subroutine and the video plays flawlessly
[CODE]............
The above code works perfectly as well
Then I try to execute the PlayVideo sub to play another file and I get a generic "Object reference not set to an instance of an object" error, that does not point to any particular line of code. It took me forever to find out exactly what line of code was causing this. So I came up with a workaround:
In the PlayVideo sub I changed the code to this
[CODE]..............
And there it is, the second video played without error. but then I noticed something, after the second video ended the .Ending event handler did not fire, actually all the event handlers basically died. So someone told me to use a timer to monitor when the video ends, and I basically laughed it off since we know that's an amateur move. After being frustrated for a while, I caved in and used the timer to do my dirty work, which I really don't like.
Now there's another problem, after I play a video in my project, DirectX is not screwed up for other programs until I restart my computer. Particularly I have a visualization plugin for Windows Media Player called Gforce. After I play a video, Gforce will not work, it gives me an "Error=18" which means that my computer does not have sufficient hardware to use it. The only way to be able to clear it up is to restart my computer.
Here are my specs:
Intel 3.0ghz Dual Core processor
Nvidia Geforce 9800GT with 1GB ram
4 GM Ram
Windows 7 64-bit version (build 7100)
Programming in Visual Studio 2008 Professional (using Visual Basic code)
I originally attempted to use the AxWindowsMediaPlayer control, but I am unable to. According to Microsoft there is a bug that prevents me from using it. When I pull up the choose items dialog box it does not show up, if I browse to wmp.dll to manually add it, I get an error ("self-registration for c:windowssystem32wmp.dll failed"). I also read that you should try to add the wmp.ocx instead of wmp.dll, but I am at a loss on this since I am pretty sure that file does not exist. I am trying to put together a new media player program for my theater pc and this video thing is putting me to a standstill. I am a highly experienced vb programmer (over 20 years), but I am not very experienced in DirectX. I have read a lot of code samples on video playback but they all give me tons of problems, so I hate to say it but i think that most of these samples were written by people who don't know what they are doing.

Im looking to play a sound from a folder which is in my debug directory. I got this working for a PictureBox: PictureBox1.ImageLocation() = ("Resourcespicture.png"). But I cant find something to play a sound. This is what I had before: My.Computer.Audio.Play("C:Users......Soundseep-2.wav"). I dont really want to be writing the location of the files using special directories. Is there any way I can just set the location of the file to the directory in which the .exe is.

I am trying to use direct sound to play a wav file, so I may animate a picture box while the wav file is playing. I have made a device object and a secondary buffer object and when I run the program I get an error message(see attached image), but after I click continue, the wav file plays and it plays every time I click the play wav button. I am using a test project to work out the bugs before I implement the direct sound in my other project. Below is the the code I am using. Can someone tell me what I am doing wrong? The code needs a form named form1, and a button named xPlayButton.

How can I play a sound based on waveform data that my .Net program is generating from user input and mathematical functions? By "waveform data" I am mean SPL values in a fixed interval time-series (probably 44.1 kHz). I presume that this requires some kind of streaming buffer arrangement.Note, that this has to be live/real-time, so just creating a .wav file and then playing that will not be sufficient. VB.net is preferred, but C# is acceptable also.

I have a program which have to play a sound at a specific time in each day.Currently I made a timer with 450 interval and I put a code in it which check if datetime.now = mytime then it will play the sound.(the program runs in background)
It is working but the problem is that sometimes it doesn't play the sound. I think I didn't used a proper way to this.I have even tried checking datetime.now.hour & .minute & .second with mytime to make sure it does play it at the right time But I don't know why the timer sometimes miss it and the play sound won't be run.
