Anyone ever play around with video manipulation?

[timeshifter]

I found a nice little .dll that captures webcam input, and I've been toying around with manipulating the image in real time. I'm having a fair bit of fun with it... not as hard as I thought it would be, either.

I got video to stream from a webcam in flash. That's as far as I go.

[MaximilianMayrhofer]

It's really just a matter of capturing each frame as it comes in, applying the desired filter and then displaying it. I hope you're using C++ for manipulation or the lag will be dreadful.

[timeshifter]

C#, and I can't complain. Sometimes it's slower than others, but I think that's just a webcam limitation. This thing is kinda old, and they aren't exactly known for mind-boggling framerates.

I love C#, don't get me wrong, but image manipulation without some unsafe methods is going to definitely show a performance hit.

i have a digital camera i paid $8 for that doubles as a web cam. Really crappy stuff. You need to be in daylight to get a good frame rate. Anyway i've done some video editing but nothing on a live feed.

As it stands right now, running any of my filters has zero impact on the framerate. I haven't put a timer in to see exactly how fast the filtering is, but I'd imagine pretty fast. Maybe I'll do that a little later today.

[MaximilianMayrhofer]

Pretty shweet! Are you keeping this proprietary or are you gonna post some fun classes when you're done.

[timeshifter]

I found a library that handles webcam I/O at CodeProject... from there, I just figured out how they were doing their filters, and set mine up on the same basic idea. It's been working pretty well so far.

Proof pl0x.

Proof attachedz0rd.

[MaximilianMayrhofer]

I am convinced by the mere presence of an attachment.

I love CC, but that doesn't mean I'm like klegg and only post in CC for poops and chuckles. I do actually code in my spare time

I'm still working on a revised version of the iCam class I released agers ago. Will support video recording this time as well as custom filters, i've found it to be pretty interesting to work with. I will check out your upload when i get home.

If you see anything I could be doing better, please do tell... I'm doing this strictly for fun (contradictory?), and I have a feeling it could turn into a whole lot of fun. I've seen some pretty cool stuff done with a webcam, and I love doing graphics stuff... this is just a merge of cool stuff!

[MaximilianMayrhofer]

So far i'm liking what I see in your code. Very efficient

[timeshifter]

*bows* Why thank you, good sir. Wossy has trained me well in the dark art of efficiency, and I've kinda put it to use where I can...

[Lord Orwell]

Think of the possibilities! Gesture detection! Throw a gang sign at your web cam and it automatically will open up your lolcats page. etc etc

Have you looked at the touchless library?

Lets just say that I find poop easier to strain out than programming code. And I'm constipated.

[timeshifter]

I'm sorry to hear that.

that is the coolest thing ever. There is some multi-touch work being done using a web cam and projector to give a multi-touch interface.

Hmm... what do you think would happen if I tore an LCD screen apart and pulled out the display sheets, and used that instead of paper? Faux touch screen?

you read my mind. I was wondering about that myself. I can only guess that it may trigger on colors you display on the screen.

You never listen to anything I say. Not ever. Hence you even thinking of using C# for a job like this.

Ho hum.

[timeshifter]

Well, it does seem to be doing the trick pretty well...

[wossname]

"Titanic" seems like a good name for this boat, it's unsinkable you know, oh my yes.

If you say so.

[timeshifter]

Stop misquoting me! I do that well enough on my own...

Oi! CC is teh l337!

[MaximilianMayrhofer]

Yea! What are we angry about again?
