[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Mauro,

This is the second 'pull-requested' version of the selection API. The patch-set introduces new ioctls to V4L2 API for the configuration of the selection rectangles like crop and compose areas.

Changelog:

- changed naming of constraints flags to form V4L2_SEL_FLAG_*
- changed naming of selection target to form V4L2_SEL_TGT_*
- size of PNG files in the documentation is greatly reduced
- fixes to handling of output queues for old cropping emulation
- VIDIOC_{S/G}_SELECTION for s5p-mixer accepts single- and multiplane buffers as VIDIOC_{S/G}_CROP did

Best regards,
Tomasz Stanislawski
