another compatibility problem

I'm trying to find a recorder, like HyperCam, that will work in Ubuntu.
I can get HyperCam to record, but it's really buggy and it takes shitty video, because I can't select a certain space to record, i have to record my whole desktop (bad compatibility with WINE).
So does anybody know of a video recorder that i can use with Ubuntu?

EDIT: Nevermind, I just now thought to check the repositories, and I think I found a program that will work.

EDIT again: FUCK. Didn't work after all. I'm trying to record a video of me doing something on a DS game. I've loaded a save on the only DS emulator that I know how to do that with, no$gba, and tried to record it with "gtk-recordmydesktop" but it says some bullshit about my soundcard not being configured. It seems to be a problem with WINE though, because if the emulator isn't running it doesn't give me that bullshit error. If I could figure out how to load save files into DesmuME (DS emulator for Linux) then I could get the recording.

(If all else fails, I'll probably just ask my stepmom if I can use her camera to shoot the video from my DS screen, but it's like 10 minutes long and I have shaky hands)

sounds like wine isn't setup correctly to work with pulseaudio
and is dominating the sound card

Run the emulator with

Code:

padsp wine /path/to/emulator

this will route the sound through pulse

OSS sends sound directly to the soundcard hardware, so only one sound source can be active per sound card
padsp redirects sound through pulse

Proper solution is to change the options in winecfg, and move sound processing over to ALSA (which pulse supports natively), instead of OSS

In winecfg sound is already in ALSA.

EDIT: I tried running the emulator with padsp wine and it's still giving me the sound card error

Ok, then we have a stubborn Windows program that doesn't follow the standard WinAPI
(£10 says same problems under native windows, all other sound sources would be cut-off when launching the program)

Open winecfg with OSS redirection

Code:

padsp winecfg

and change the Audio to use OSS

Close winecfg
then launch emulator with

Code:

padsp wine /path/to/emulator

gtk-RecordMyDesktop is a pretty good program, although it encodes it in Ogg Vorbis, so you might want to encode it to something else when it's done.

Still getting the error.

Code:

Cannot Open/Configure Sound Card.

Any particular program you suggest I do it with?

Well, use a native DS emulator

The emulator wants to directly control the soundcard, yet you're trying to shoehorn it through 3 levels of redirection

Use a native emulation program

I tried to use DeSmuME, but I can't figure out how to load a save file into it, it makes me start a new game.

Is hypercam a in-game recorder?

Have you tried FRAPS?

Hypercam is the problem, I've already tried it.

And no, I haven't tried FRAPS, somebody told me it just took screenshots.

Fraps record videos all right, but only 3D applications.

You could try camstudio, if you're recording in wine.

I believe you are wrong about that.

FRAPs records anything. Just hit the hotkey (F9 I think) and it'll start recording. The only problem is that the free version will only record up to a minute every time you hit the record button, and that if you record a video in a game the file size will be really big as it doesn't compress it in the free version.

Slayer,
Fraps is a windows program...

What's wrong with Ogg Theora?
being a free and unencumbered format, you can do a lot more with it than a lot of other formats
the only thing that comes close is XviD

The support for it. Very few applications have it.

:shock:
what platform are you on?
Ogg's the most supported format on Linux....

Plus, it'll be in HTML 5, so it'll be all over your browser in the next few months

Why, Windows of course. But it's virtually unsupported on other devises, like phones.

No, they didn't agree on including it - or any other codec - in the specifications for HTML 5. Many browsers will probably still add support though. (and it's not like I can't play it on my computer - it's just that generally it's unsupported)

Well either way, I still don't have a way to record anything on my emulator.
;_;
FRAPS, being a Windows application, will probably give me the same error I'm getting with HyperCam. Only being able to record one minute at a time? Haha. Not worth it.

well, slap the windows dev's around
there's no excuse for not supporting it

Re: HTML 5
They took out the explicit ogg theora support cause apple & MS moaned (MS wanted it's own WMV, and Apple wanted H.264)

but it's already in Firefox 3.5, Google Chrome and Opera, so expect sites to take advantage of it

http://www.dailymotion.com/openvideodemo
http://open.bbc.co.uk/rad/demos/html...de2/index.html
etc.
etc.

Ogg Theora will be the de-facto standard HTML5 video format

Most modern phones run on Linux (with the obvious exception of the iPhone), so phones are not an issue

You need a native DS emulator
Then you'll have far better control over where the sound goes

You can probably do it (with some work) on your current emulator, but that's the type of operation that really needs to be done in the flesh, and not back & forth over a forum

I have DeSmuMe, native DS emulator for Linux, but I can't figure out how to load a save file. And that's the whole point here, I need to load the save file so I can record my self doing something on it.

H.264 supports hardware acceleration though, while Ogg Theora does not.

Wrong way round

Hardware manufacturers support H.264 decoding directly on the GPU, and export this feature (via the driver) down to userspace apps

There's no reason why any random video codec couldn't be supported by GPU's
but it's a chicken & egg thing
manufacturers aren't going to do it without demand
demand is slow up the uptake without hardware acceleration

*edit*
this is one reason open drivers for hardware is important
then the devs developing any codec can add support for hardware decoding themselves

I'd suggest you just try doing it in Windows. So much easier.

Really? Hmm. I guess things have changed since last I looked it up.

Yeah, open drivers would be sweet. What have they got to hide anyway? It's the hardware they make money on.

I don't have Windows anymore.
And I really don't think I'm gonna resinstall Windows just so I can record something off of a DS gamesave.

At the risk of sounding insane...
If there are sound problems only when you use gtk-recordmydesktop:

Run another ubuntu in virtualbox. DS emulator (in wine) can directly access the (virtual) soundcard there. Sound in virtualbox can run through pulseaudio. Then you can use gtk-recordmydesktop to record your (real) desktop.

I count a ridiculous amount of indirection there, but it should work :P.
