Some vendors routinely implement new formats without bothering to send a patch for the uvcvideo driver. It would be easy to do so, but it requires knowing which format is meant by the GUID. Most format GUIDs are of the form 32595559-0000-0010-8000-00aa00389b71 that starts with a 4CC, but that's not the case here. Could you send me the output of lsusb -v -d 0bda:58f4 running as root if possible ? -- Regards, Laurent Pinchart ^ permalink raw reply [flat|nested] 11+ messages in thread

I've recently come across of similar format using D3DFORMAT instead of GUID. According to the vendor*, this camera module includes an infrared camera (340x340), so I suspect this is to specify the format it outputs. A good guess to start with would be that this is D3DFMT_X8L8V8U8 (0x32). To test it, you could map this V4L2_PIX_FMT_YUV32/xRGB and see if the driver is happy with the buffer size. Then render it to make sure it looks some image of some sort. A new format will need to be defined as this format is in the wrong order, and is ambiguous (it may mean AYUV or xYUV). I'm not sure if we need specific formats to differentiate infrared data from YUV images, need to be discussed. *https://dustinweb.azureedge.net/media/338953/xps-13-9370.pdf > [ 2.341450] uvcvideo: Found UVC 1.00 device Integrated_Webcam_HD > (0bda:58f4) > [ 2.343371] uvcvideo: Unable to create debugfs 1-2 directory. > [ 2.343420] uvcvideo 1-5:1.2: Entity type for entity Extension 10 was > not initialized! > [ 2.343422] uvcvideo 1-5:1.2: Entity type for entity Extension 12 was > not initialized! > [ 2.343423] uvcvideo 1-5:1.2: Entity type for entity Processing 9 was > not initialized! > [ 2.343424] uvcvideo 1-5:1.2: Entity type for entity Camera 11 was > not initialized! > [ 2.343472] input: Integrated_Webcam_HD: Integrate as > /devices/pci0000:00/0000:00:14.0/usb1/1-5/1-5:1.2/input/input10 > [ 2.343496] usbcore: registered new interface driver uvcvideo > [ 2.343496] USB Video Class driver (1.1.1) > [ 2.343501] initcall uvc_init+0x0/0x1000 [uvcvideo] returned 0 after > 5275 usecs > ``` > > Please tell me, what I can do to improve the situation. > > > Kind regards, > > Paul > [-- Attachment #2: This is a digitally signed message part --] [-- Type: application/pgp-signature, Size: 195 bytes --] ^ permalink raw reply [flat|nested] 11+ messages in thread

This is much more likely yes. So maybe it's the same mapping (but with the -00002- instead) as what I added for the HoloLense Camera. > > > To test it, you could map this > > V4L2_PIX_FMT_YUV32/xRGB and see if the driver is happy with the buffer > > size. > > VideoStreaming Interface Descriptor: > bLength 30 > bDescriptorType 36 > bDescriptorSubtype 5 (FRAME_UNCOMPRESSED) > bFrameIndex 1 > bmCapabilities 0x00 > Still image unsupported > wWidth 340 > wHeight 340 > dwMinBitRate 55488000 > dwMaxBitRate 55488000 > dwMaxVideoFrameBufferSize 115600 > dwDefaultFrameInterval 166666 > bFrameIntervalType 1 > dwFrameInterval( 0) 166666 > > 340*340 is 115600, so this should be a 8-bit format.

I think we need such a mechanism, yes.

Would you like to propose one ? :-) Ok, meanwhile I've looked over how this camera was used. It seems that's it's combined with a IR light in order to create a near field depth. As we already exposes couple of depth sensors as GREY, I think your patch is ok, and should be merged. It's not really clear in general how the driver can really figure-out what type of data is delivered.
