start with IPO: Input, Process, Output.
what do you want to encode?
how do you want to encode it?
what purpose do you want the output to fulfill?
encoding is changing one thing to another:
compression is a form of encoding to save space.
ecryption is a form of encoding to hide the output from undesirables.
serialization is a form of encoding to transfer a binary object as text
etc.
So simply asking for help in encoding, help me now, please, won't get you far. Start by defining the problem, define it well. Once you can define it, you start breaking it down to its parts. IPO is an archaic method, but it still works especially for new programmers. Break it down into sub groups of functional parts, each with an IPO definition, each does only their small part. Put it all together, and you have a program.
BUT, first you have to start by defining it.

Thanks for such an inspirational answer. I really appreciate it.
I want to encode a video using Visual Studio C++. I want to get a compressed video as an output.
How do I start breaking it in parts? Do you mean should I start writing what I need to input, then process and then finally output?
I really appreciate the help.Thanks very much.

have you got the video to input? if not, you start there, how do you get the video.
Once you have everything needed to get the video into the design, then you need to compress it.
Do you want industry standard compression? do you want to use 3rd party libraries to do the compression for you? do you want to write your own compression? Is it for archival? Is it for streaming videos across the network? do you need high compression over low-latency? The questions just keep adding up. You answer them, figure out what you need to do that and move on to the next.
Are you writing the display? DirectX? OpenGL? (someone else here is doing video to texture -- you two might help each other).
there are libraries to do video compression, but that may not be what you need.

Your question is a little vague; an encoder of what?

I have made a dialog based MFC app but found a big problem. If someone is entering values into the edit boxes and then hits enter it closes the program. If you hit enter at all while the program is running and in focus it will end the program. How can I fix this?
Thanks

You can override OnOK() (and possibly OnCancel()) and in your overridden method,
do nothing.

Hi I cannot find those functions anywhere. I have this
CDLIADlg dlg;
m_pMainWnd = &dlg;
INT_PTR nResponse = dlg.DoModal();
return FALSE;
Brings up the main dialog, but I can't find the OnOk or OnCancel in the main dialog
|

|
|

They are virtual functions declared in the CDialog class. You can
add them through the class properties window or add them by hand
virtual void OnOK();
virtual void OnCancel();
...
void CDLIADlg::OnOK()
{
}
void CDLIADlg::OnCancel()
{
}Mark

whats up ??

Since noone else has replied...
Your code as shown compiles for me (if I add the missing semicolon
and comment out the "[..]") with no errors/warnings.

both since I can't compile I can't run

Hmm since I copied the code and compiled it, I can only assume your'e not
showing us something

my last post has the source code which still don't compile with me

Just a guess, but are you sure that when you compile your test program that the code
<br />
class __declspec(dllexport) CRC32
becomes
<br />
class __declspec(import) CRC32

I guess it does I just replaced the EXPORTS macro Visual Studio made for my code to be explicit on the forum.
btw I'm using visual studio 2008 beta 2

Hey there, I was wondering if someone would be willing to show me how to capture a frame from a webcam and turn it into a texture in OpenGL.. I'd like to do this realtime so the webcam is displaying in my OpenGL project. If anyone has some tips that would be great.

This really is two completely different parts to your question...
1/ grabbing a picture from a webcam,
and,
2/ Now I have a bitmap, how do I turn that into a texture and use it in OpenGL.
You'll have luck researching each of these parts, but I doubt anyone will give you the whole thing on a platter.
My guess is that the camera will provide a TWAIN interface for grabbings pics, but I don;t have any direct experience?
