Connecting a camera by firewire: decoding error messages
I’m trying to connect a camera by firewire, in order to record from a jitter patch. I’m getting some error messages:
- Could not create class enumerator for the requested type
- Couldn’t add capture filter to the graph
Is there a place where error messages and some explanations are published?
Thanx
Robert

Sounds like a driver/OS incompatibility issue. What OS, computer model and camera are you using? Running Vista?

Thanks for the reply.
OS: Windows XP
Computer: ASUS motherboard, Intel duo CPU
Camera: Sony Z1u (in DV mode).

Are you getting no video in?
Do you have a 32 or 64 bit XP install? I’d recommend finding the latest drivers for this camera and seeing how that goes.

I’ll check on the video in (using Jitter) this evening. I certainly have it with Premiere Pro, so I think the drivers are there.
I’m using 32 bit XP.

I tried the jitter test and was able to obtain playback from the camera in Jitter. So the XP driver would seem to be in place and working, at least for input.
However, in my patch now, I’m getting:
jit.dxvideoout could not create JitterPush source
Does this still indicate driver problems?

BTW: I’ve downloaded and tried using FRAPS, and it handles the video well, but it can’t capture the audio from my Phonic Helix Board 12 Firewire MKII, running its own ASIO driver. Since my goals for my present JITTER project involve additional inputs through the Phonic interface, I don’t want to not use it.
Thanks

For now, went with FRAPS. Made a nice test, up on VIMEO. Hoping to find a way to record it in real time while projecting it.

FRAPS seems like a good answer for capturing audio and video–I just switch to the motherboard’s local audio system for recording the audio.

This is an update to an older posting, in case it is helpful to someone out there.
Over the last year, I’ve been using FRAPS on a Windows XP computer to capture the output of my ever-developing patch. It slows my frame rate down, but it has worked.
I’ve recently switched to a MacBook Pro laptop, and spent a couple of days with my Sony Z1u camera. Using the jit.qt.videoout patch. My experience is that I can export the signal into the camera but only in a standard definition DV resolution, not in the 1280X720 res that I’m using in my patch. Other HD cameras may not have the same result, but that’s what I’ve found after a couple days of trying with the Z1u.
Another thing I found: I wasn’t able to make a direct connection between my MacBook and the camera using a firewire 800 to firewire 400 (4-pin) cable. I WAS able to make the connection when I looped from the laptop Firewire 800 through a Firewire 800 external hard drive, then came out a firewire 400 (6-pin) port on the hard drive and into the firewire 400 (4-pin) port on the SONY. I don’t believe this reflects anything about MAX/Jitter, I think it’s about the hardware. Anyone looking for another way around this might try a firewire 400 port ExpressCard/34 connector, if your MacBook has an ExpressCard port.
