Linking Video Codec DLL To A VB Program?
Jun 14, 2009
I have a AVI program that uses no ocx, controls or api but I would like to support codecs. Is there anyway to send the parsed raw frame compressed stream data from an avi to a codec's dll that i found from the FourCC in the system registry and have it return a DIB or some type of image that i can display?
I already can display images from a uncompressed avi (although only by writing the raw data to the hard drive with a custom header file and then loading the bitmap, because the DIB is backwards and RGB is flipped) and extract the audio sources to the hard drive with a header if its wav. Also I can display subtitles from srt files (cause they are easier to read) using a custom alphabet bitmap image I made.
even if you only know what this is called or have a link to a rfc that would be nice.I would guess there is some sort of standardization of calling codecs and ive tried looking at the source code of some codecs but im not very good at C languages.how to flip that raw data so that it can be displayed by a bitblt without running thru each pixel so its fast enough to display, cause i cant get it over about 26 fps going thru the hard drive.

I 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?

I've come across what may be a rather idiotic question but my understanding of codecs is extremely limited. I'm attempting to create a VB.Net media player, either using the Media Player COM component or by doing grunt work by myself. What's been bothering me is Codec's. Will both players automatically use an installed codec when trying to play an ".mkv" (just for example). Or will I need to interface the application with the codec.

I have 1 project with about 7 forms. On each form I have 6 x 4 responses radio buttons (i.e. a multiple choice quiz). If the correct response is selected, the examinee gets 1 point, else 0. At the end of the quiz, the examinee can click a button that will add up all the correct responses & display the % correct. How do I program the button to do this given that data are on 7 different forms? [URL].

How to Create Video Games in VB.Net
I realize that this is a very popular subject, especially amongst budding developers. The drive to create games may be the reason you started working with Visual Basic in the first place. After stepping through a few samples and getting the hang of working with user controls on a form, it may be very tempting to start to throw some PictureBoxes and a Timer on a Form and start to implement some game logic. Seems easy enough, right?
To some extent, this is a true statement.You could start to do this and it would be easy enough¦ at first. But when you begin to try to calculate collision and animate or rotate your sprites, you may start to run into some difficulty. And attempts to circumvent the problems often lead to even worse issues.This can cause an endless spiral of misery which could leave you thinking VB just isnt meant to make games!
The initial problem that most people face is the desire to use a PictureBox (or any other control) as the logical Sprite¯ container for the elements in the game. It makes sense since the control appears to provide a lot of the required functionality already and its easy to extend it with more properties as needed.
The issue though is that Windows Forms Controls are designed to be drawn statically“ that is, they arent meant to move around in real-time. You can of course move them at run-time, but this is normally an on-demand operation (something which occurs because the user just took an action like clicking a button or menu item). Attempting to move controls in real-time puts a heavy strain on your application and can cause poor performance quickly.[code]....

How would you make a program that recognizes your eye, or something...
dim eye as string = picturebox1
if eye = picturebox2 then
msgbox("It's your eye",64,"Yeap!")
Or if it's too complex maybe just recognize the color?

Basically I download lots of TV shows and they're never named in the way I like; they're named like this "The Office.S06E22.HDTV.XviD-NoTV."So I was wondering if I had a .txt file with all the episode names I could make a program to rename all the video files in the right order so they're named like this "The Office Season 6 Episode 22 - Secretary's Day."So I want to copy and paste a list of correct episodes names into a text file. Then I want to read the text file, which I already know how to do. Then, and this is the bit I'm struggling with, I want to read the text file, one line at a time, and it renames the top video file with the top episode name and so on.

I've made a video player, that can play almost all popular video formats. But the problem is that I want to add a pan & scan effect to the end user, also if possible a overscan effect also. I'm using MSVidCtl to view and then MSVidFilePlaybackDevice to play and control the file, I've searched the net a lot but found nothing helpful especially in VB.NET, I can use managed DirectX directxaudiovideoplayback.video but the same problem exists, can't find a way to add these pan & scan, zoom in and overscan effects.

I 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.

One of the things my VB.NET program does is play video files using the Windows Media Player component that comes with VB. My program also switches the WMP component to full screen but once in a while the form will be on top of the full screen video. I am hoping that you fine and knowledgeable folks cat this from happening. The problem occurs when the next video file is played automatically. I'll do my best to post a bit of code but since I don't have much of an idea what might be causing this I'll just have to guess. The project has gotten quite large over the years I've been writing it and if any more code ito post any or all of it, though I'm sure no one would like to go through all 1771 lines of it.

I am creating a bulk media converter. In order to do this I need to go through each line in a list box one after the other and run the conversion function. I am trying to use the following:
For Each item In listVideos.Items

However this makes the program want to convert all videos at the same time... is there anyway to get the program to convert one video and then after the conversion code is completed to move to the next one?Should also be noted that I am using FFMPEG for this project.
