Improvement in Webcam support

(1/3) > >>

Neil Waldhauer:
Starting with Arca Noae USB drivers version 12.16, Webcam support is working with USB 3.0 on all the machines/webcams I have available to test. Prior to this version, USB webcams only worked with the USB 2.0 drivers.

The function is nice and fast, and I see no lag with the picture. Laptops with webcams that are attached with USB 3.0 tend to be much higher resolution, probably because they are newer.

I am using WebCam, UVC Webcam Support for OS/2 (ArcaOS, eComStation) by Wim Brul.

Lars:
I had helped porting libuvc (that in turn makes use of libusb). Whatever app uses libuvc should do. I have a test app from somewhere that I used with my "Logitech QuickCam Fusion" camera (0x046d == desc.idVendor) && (0x08c1 == desc.idProduct) where the camera claimed to not be UVC compliant (it claimed to be vendor specific) but in fact it was (as a workaround, I added a hack in libuvc to support that camera).

Martin Iturbide:
Hello

I will have to re-test some webcams that I have around.
This is the list: https://www.os2world.com/wiki/index.php?title=Category:Cameras

I don't remember if I ever made an USB Webcam Microphone work with ArcaOS. Was it possible? if so, anybody remember the steps?

Regards

I think the problem will be that the audio interface will be supported by USBAUDIO.SYS / USBAUD2.SYS but the video interface will be supported by USBCALLS/libusb/libuvc as we do not have a dedicated USB VIDEO driver.

And therefore, the audio and video data streams are not correlated or would need different means to correlate them as in that case, audio should also be handled by USBCALLS/libusb and then the two data streams somehow bundled in a container (I think that was what matroschka was good for).

Dave Yeo:
In theory, you could pipe the audio and video through FFmpeg and into a container such as matroska or better webm. Syncing could be a problem though.
