im new to VB and i would like to ask some questions;Im developing a Media Study Room program and i have this little problem, My problem is that, how can i designate the video in the list box, that when i click variable on the list, it will automatically play the video i designated to a number and its description in the bottom will appear.
View 18 RepliesThis is tied in with the other discussion that I started last week about playing audio files using the DirectX classes. If you haven't yet had a look at that other thread,Using the same reference as in the audio application, let's set up a form for video this time. I started with a form that I then placed a split container on and in the lower panel of the split contatiner, I placed the buttons and other controls. Following is how I have mine set up:
Reread the thread on the audio player because the methods are very similar - in fact some are identical! However, this is video and it got a bit more involved as you might expect.The full code is here and I hope you'll find it useful to you. Following is a screenshot of the end result.
I have tried to play a Camtasia video inside a web browser control but it comes up with javascript needs to be enabled error on page. How can I work it or find a work around that? I'd like to have a listbox that contains the movies and they would play in the browser. I have a membership site that I'd like to have a player that authenticates the user before playing them but first things first, what is the best way to accomplish playing Camtasia videos inside a form?
View 25 RepliesI have a full screen button, so that when it is clicked the windows media player control will go to full screen. This works fine, however I need a way to check that the video has started to play before the button can be pressed to make it full screen.

View 5 RepliesIm trying to do a video player but i have to play this video from the buffer, is this possible.. Let me explain you much more complicated,a got a CryptoStream and im decryting the video
While lngBytesProcessed < lngFileLength
'Read file with the input filestream.
intBytesInCurrentBlock = fsInput.Read(bytBuffer, 0, 4096)
'Write output file with the cryptostream.
[code]....
This code writes my decryted or crypted video to a new file. However, i need to play the video file from the buffer(without copying to a new file), in other way it would be meaningless if i create a decryted file. in other words it would unsecure for me cuz if anyone can locate my temp directorey they can copy my decrypted video files.
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.
How do I tell if a Video is finished playing?

I'm looking for a way to extract .jpg files from .wmv files at given intervals. For instance, if a clip is 1 minute long and I ask for 6 thumbnails, it will give me one every 10 seconds.Can anyone point me in the right direction for anything that may already exist for extracting single frames from video?

View 3 RepliesBased on a thread earlier today, and in particular an answer that Cor gave wherein he
pointed to this article, I thought that I'd do some investigation. Many times here the question has come up about playing .mp3 audio files and NOT using the Windows Media Player object. In the article referenced above, he shows how this can be done via DirectX.
I've looked at DirectX before and it seemed ambiguous so I never really dug into it but it turns out to be pretty simple actually! I thought that I'd write this as a step-by-step of what I did so that maybe some of you will find use from it. The whole thing stems around using DirectX and to begin with, you'll need to download and install the SDK for it. If you haven't already,
try this link. Do be aware that it's a large download (about a half gig)! Once that's installed, create a form and add a reference to the class that we need for this. You can do this several ways, but the way I usually do is to right-click on the name in the Solution Explorer, then choose "Add Reference":

Is it possible to play 8 different and individual mono wave files to a 7.1 (8 channels) audio system using vb.net? (I undestand that the .1 speaker is the subwoofer and I'm not yet sure it can be replaced with an ordinary speaker.) The playing should start simultaneously and the files can be of different size/length.Is this something that should be done using win API functions if it can be accomplished at all.I just re-installed my old VB6 which I need to ugrade and vb.net would be the easiest for me so I placed this Q here.
View 2 RepliesI am working on an application in VB.net (.NET 2.0) where I need to open a dynamic amount of different audio streams. Normally, for audio files, one would suggest importing the Windows Media Player COM reference and adding a GUI-based element from the toolbox, but since I'll be working with a dynamic amount of these a GUI would be a terrible idea (especially with Tab stops).
View 4 RepliesWe have code in our former VB6 application, that ported fine to VB.NET, that plays a simple AVI file of the typical "flying folders" and "spinning maginfying glass" AVI. Under Windows XP, our application ran fine and everything was good.
Then we had customers start using Vista and Win7 and this stuff crashes. We were using the MS Common Controls (SP4) and then (SP6) - utilizing the Animation player. Now - these dont work and we get nasty errors.
I searched Microsoft and the web to answer the "what now?" question and though there are numerous suggestions, none of them work. We cant use Media Player because we dont want any menu - just the graphic. We dont know why, with the cool tools given in .NET, there is no animation player (seems a huge oversight...) But we need to get "unstuck" on this one, and we need that fast...
So, How does on play a simple AVI file using VB.NET code? What DLL or OCX does Microsoft recommend and is there a place we can find some sample code for it?

View 2 RepliesBeen doing VB2010 for about a year now, have recently started to push the boundary's for what kind of media I can incorporate into my forms. I haven't been able to play .wav or .mp3 files though. I have tried to follow tutorials on microsoft and other coding websites without success.
View 1 RepliesI'm trying to make a "Simon" game with four buttons labeled 1-4. The game is supposed to read the numbers out loud, but i have a problem with that. I have 4 wav files from google text-to-speech, each named 1-4. I made an number generator that can return like this "42331", and the game is supposed to play 4.wav, 2.wav, 3.wav, 3.wav and 1.wav.
Here's what I got so far.
Public Class Form1
Dim rnd As New Random
Dim i = 0
Dim level As Integer = 5
Dim nums As String
[code] .....
It only plays 1.wav (the last in the sequence).
I have a program that speaks wave files. This works problemless with the Soundplayer class with the following code:
Sub MyPlayWav(ByVal WavFileName As String, ByVal StartPos As Long, ByVal EndPos As Long)
Dim wp as new SoundPlayer
wp.SoundLocation = WavFileName
wp.Play
End sub
The soundplayer does however not seem to have a method to play the wave from position StartPos to position EndPos and achieving just that would mean quite a reduction in downloads of these files.
The soundplayer does have a stream object, and that does have a seek method, suggesting that there might be a way to accomplish this, but how?
I plan to include other media files as I am developping the project, and I guess I will be confronted with the same problem.
I am having a _ton_ of issues, and I am hoping some of you could clear it up...
1. OK So a while back someone showed me an example for fonts from resources, but I noticed if you close the window that it opens, The entire program shuts down... what can I do to fix it?Also, The fonts are not showing up on all computers, only this one....
2. I am trying to delete a image file, which the program downloads from the internet, and can change regularly, but when I try to delete it will not delete. It says its in use, and I cant figure out where.
3. I am trying to play videos using the following
vb
Private Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" (ByVal lpstrCommand As String, ByVal lpstrReturnString As String, ByVal uReturnLength As Integer, ByVal hwndCallback As Integer) As Integer
Const WS_CHILD As Integer = &H40000000
[code]....
Now, I have confirmed the files it is attempting to play are in fact valid video files. It refuses to play all but the last one.
I am having a problem with converting video files to .flv files. I am using ffmpeg.exe tool to achieve this. Here on my local server when I use ffmpeg.exe tool with c# code everything is working good. But when I deploy the same code with ffmpeg tool on to my hosting server, where as .exe files are not allowed to execute, the code is not running. Is there any other way to achieve the same other than redirecting to video conversion sites because I want to save .flv files on my hosting server.
