View 3 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.
Im 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.
My program lists all my home movies filmed with various video cameras.When I select the video from the listbox, Windows media player plays the video.However, I would like to know the dimentions of the video before it is loaded.I could,therfore, tell which camera was used to film it.Some video is 1920 by 1088 frame width/height Some is 1280 by 720 and some various other sizes Is it possible for VB 2010 to give me the dimentions ??

View 5 RepliesI have a vb.net project which i have inserted pictures and video. I inserted a video clip using the Windows Media Player control and it does work. The issue i have is that i can't move the program to another computer because the pathname for the video will be wrong. I know i could change the pathname when i move it but this is not practical because i need to present this program. Does anybody know how to make the video accessible no matter what location the program is at?
View 6 RepliesI am monitoring 12 video feeds from video cameras. Now I have more than 12 cameras, I have 134. But I will only monitor 12 cameras at a time. By Monitoring I mean, I have 12 small video screens on the form that I can see the video. The way I know which cameras are active, so I can monitor them is by a boolean value in a sql database. I run a Store Procedure in my program, and spit out the results in a XML file. I then read the XML file in a loop. This XML file will have a list of the camera names I need to monitor.
So that is for 12 video feeds. Now, I want to have a NEXT or FORWARD button on my monitor form. So when I click this it will give me the next group of cameras, 13 to 24. Now if I only have15 cameras that are active, that means the first group is 1 to 12, then the second group is 13 to 15 cameras. So I will only have 3 to monitor on the second grouping. One thought I had was to have another field in my table to mark as already as an active monitor, so when I run the SP, i will not select that row. But I need to select 12 at a time. Or I can make a number of xml files, one xml file for each grouping of 12, but I need to figure out how I can select the next group without re-selecting the first group. I have no code at the moment, I'm on my non-programming computer.

I have an application that allows the user to upload information from and Excel sheet. Since the user is more familiar with Excel, they prefer to do it this way. My software will close the workbook with Me.exApp.Workbooks.Close() , but if you have the task manager running, you can see the Excel application continues. I know the workbook is closed, b/c it asks if you would like to save changes. One instance of Excel will close when the program is exited, but the user normally builds a folder of Excel files and does them all at once. If 8 instances of Excel exist, only one will close with the program.
