[PATCH] dev-capture.rst/dev-output.rst: video standards ioctls are optional

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

 



The documentation for video capture and output devices claims that the video standard
ioctls are required. This is not the case, they are only required for PAL/NTSC/SECAM
type inputs and outputs. Sensors do not implement this at all and e.g. HDMI inputs
implement the DV Timings ioctls.

Just drop the mention of 'video standard' ioctls.
