| | | | | | | | | | | | | | | | The intervals pointer is incremented for each interval when parsing the format descriptor. This doesn't cause any issue as such, but gets in the way of constifying some pointers. Modify the parsing code to index the intervals pointer as an array and increment it in one go at end of parsing. Careful readers will notice that the maxIntervalIndex variable is set to 1 instead of n - 2 when bFrameIntervalType has a zero value. This is functionally equivalent, as n is equal to 3 in that case.

* media: uvcvideo: Don't expose unsupported formats to userspaceLaurent Pinchart2023-06-021-5/+11
| | | | | | | | | | | | | | | | | | | | | When the uvcvideo driver encounters a format descriptor with an unknown format GUID, it creates a corresponding struct uvc_format instance with the fcc field set to 0. Since commit 50459f103edf ("media: uvcvideo: Remove format descriptions"), the driver relies on the V4L2 core to provide the format description string, which the V4L2 core can't do without a valid 4CC. This triggers a WARN_ON. As a format with a zero 4CC can't be selected, it is unusable for applications. Ignore the format completely without creating a uvc_format instance, which fixes the warning.

* media: uvcvideo: Remove format descriptionsLaurent Pinchart2023-01-151-22/+2
| | | | | | | | | | | | | | | | | | | | The V4L2 core overwrites format descriptions in v4l_fill_fmtdesc(), there's no need to manually set the descriptions in the driver. This prepares for removal of the format descriptions from the uvc_fmts table. Unlike V4L2, UVC makes a distinction between the SD-DV, SDL-DV and HD-DV formats. It also indicates whether the DV format uses 50Hz or 60Hz. This information is parsed by the driver to construct a format name string that is printed in a debug message, but serves no other purpose as V4L2 has a single V4L2_PIX_FMT_DV pixel format that covers all those cases. As the information is available in the UVC descriptors, and thus accessible to users with lsusb if they really care, don't log it in a debug message and drop the format name string to simplify the code.

| | | | | | | | | | | | | | | | | | | This patch aims to add UVC_GUID_FORMAT_H265 High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2. They describe the same video encoding method. So for handling their behavior is the same. However, when external camera device describes this encoding method, some use hevc, some use h265. There is no uniform specification to describe this encoding method. So if an external camera device use h265 to describe this encoding method, driver will not recognize it. Therefore, this patch is to enable driver to read HEVC/H265 and convert it to V4L2_PIX_FMT_HEVC.
