[PATCH AUTOSEL 5.10 56/76] media: coda: limit frame interval enumeration to supported encoder frame sizes

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

 



From: Philipp Zabel <p.zabel@xxxxxxxxxxxxxx>

[ Upstream commit 67e33dd957880879e785cfea83a3aa24bd5c5577 ]

Let VIDIOC_ENUM_FRAMEINTERVALS return -EINVAL if userspace queries
frame intervals for frame sizes unsupported by the encoder. Fixes the
following v4l2-compliance failure:

		fail: v4l2-test-formats.cpp(123): found frame intervals for invalid size 47x16
		fail: v4l2-test-formats.cpp(282): node->codec_mask & STATEFUL_ENCODER
	test VIDIOC_ENUM_FMT/FRAMESIZES/FRAMEINTERVALS: FAIL

[hverkuil: drop incorrect 'For decoder devices, return -ENOTTY.' in the commit log]
