Hi ALL
Is there is anyway to show my webcam in my MASM Application
If there is any way to do it without any DLL please tell it first!!
:dance: :dance: :dance: :dance: :dance:
Beshr,
MASM can do anything you want, that is not the problem. The problem is how. You need to contact the maker of your WebCam to see if they have have a set of APIs that can be used to access the WebCam from your programming environment. Do not tell them it is assembly, say C++, if they ask or you risk scaring them away. As far as accessing the cam without using a DLL, my guess is you should forget that idea because the APIs would be useless to you as you would have to write the drivers yourself. Stick with the APIs if they exist. If they have nothing to offer, it will be a tough go for you.
Good luck, keep us posted,
Paul
Haven't looked into it, but I'd check to see whether DirectShow has anything to offer. I'm pretty sure there will be a 'standard' interface to access a webcam, it's just a matter of finding it :bdg
thx!
i want to use API because i heard that they'll be faster!!
dll are fast! but API is faster!!
is that right!?!
:dazzled: :dazzled:
In short, the API functions come from DLLs. So, no, not really.
(The only 'speedup' between using an api function and your own dll is that your dll will not have been loaded yet, but the dll containing the api functions may already have. But apart from this initial loading, there should not be any difference.)
An image viewing program I have used will connect to my webcam using twain32,
it will display video and capture snapshot images.
The program didn't come with the webcam, and worked with a previous webcam
I had from a different manufacturer.
Search for information on using twain_32.dll twain.dll or twain32 source code.
Scronty has some source you can learn from:

Make sure Phil gets some credit.

Also note that some webcams have a frame-rate limit, so even if you could access it faster, it might not make any difference. Realistically, any API you could use should be thousands of times faster than the camera, so I would not worry about making your own code. Use a .dll if it exists, it will save you a lot of time and energy. :U

I found a lot of information at http://www.twain.org , but didn't use it myself. (not yet)
Interesting. I tried to port that code to MASM syntax, and found the API calls in VFW32.INC, but there is no VFW32.DLL on my system. There is however a MSVFW32.DLL. Investigating...

We have gone over this before. We need to update MASM with the new msvfw32 files.

MSVFW32.DLL doesn't seem to have all the same APIs in it that AVICAP32.DLL does. So I made import libraries for AVICAP32.DLL and a sample project. I cannot test it as I don't have a webcam. I do know however, that the save-bitmap function is not working. I have to go, perhaps someone else can finish this.

Hello
This is an example that uses vfw32.lib and saves a bitmap
I did test your avicap32.lib, it works OK.
( my proggy uses "capGetDriverDescription" which is not in your lib )

is there like a secret password or something to access them ?
nice examples
yah - they totally wiped out this thread...

which would have had some interesting code to learn from

No.
hutch, had to make room by deleting attachments, for the growing database of messages, who is the leading reason for lots of messages, "Neener Neener Neener" ???
There is always cause to effect.

oh - i see
you're gonna blame me, huh

If you want to claim all the messages in the database, and have shoulders wide enough to carry the MASM32 website for responsibility, I will not stop you.
Between your perspective and attitude lies an answer. Choose Wisely !!!

i dunno what rock you crawled out from under - lol
but, you can go back there, any time
the reason i have a lot of posts is because i try to help a lot of newbies
quite often, i have seen a question asked - and it sits there unanswered
i dunno - maybe that's not what they want the forum to be
i guess Hutch has to decide what he wants it to be, and make decisions, accordingly
but - you can jump in there, any time and try to help
then you can have a few more than 1200 posts, too

I am a very primitive programmer, back to when evolution was 4bits, I love clubbing bits, bytes and code timing.

Take your own "

If it gets any deeper, we may need to split(anagram coming soon) the thread, spit(oral refuse) goes one way and the slit(camera openning) goes another.

P1 and DenDave.. you're from the same 4bit era as many of us... cool down dudes - we all have our moments :wink
I think I have some nice webcam stuff saved, and half dev'd a cam proj myself.. somewhere..maybe I can upload it...
If I can find it...'old-timers' kicking in
:bg
it's the GDI+ stuff i was interested in - and image conversion/loading
no worries - i will do it on my own
I do not know if I'm doing the right thing in re-posting that file here. If not, please, say and I will follow your comments.
thanks :U
Yeah Calm down @ P1 and Dave :dazzled:
If there is a problem.... Fighting is not a solition Sure We can solve it without fighting also
there are still attachments around here :toothy
