media: uvcvideo: Support multiple frame descriptors with the same dimensions
The Microsoft HoloLens Sensors device has two separate frame descriptors
with the same dimensions, each with a single different frame interval:
VideoStreaming Interface Descriptor:
bLength 30
bDescriptorType 36
bDescriptorSubtype 5 (FRAME_UNCOMPRESSED)
bFrameIndex 1
bmCapabilities 0x00
Still image unsupported
wWidth 1280
wHeight 481
dwMinBitRate 147763200
dwMaxBitRate 147763200
dwMaxVideoFrameBufferSize 615680
dwDefaultFrameInterval 333333
bFrameIntervalType 1
dwFrameInterval( 0) 333333
VideoStreaming Interface Descriptor:
bLength 30
bDescriptorType 36
bDescriptorSubtype 5 (FRAME_UNCOMPRESSED)
bFrameIndex 2
bmCapabilities 0x00
Still image unsupported
wWidth 1280
wHeight 481
dwMinBitRate 443289600
dwMaxBitRate 443289600
dwMaxVideoFrameBufferSize 615680
dwDefaultFrameInterval 111111
bFrameIntervalType 1
dwFrameInterval( 0) 111111
Skip duplicate dimensions in enum_framesizes, let enum_frameintervals list
the intervals from both frame descriptors. Change set_streamparm to switch
to the correct frame index when changing the interval. This enables 90 fps
capture on a Lenovo Explorer Windows Mixed Reality headset.
