[PATCH v3 0/2] Add resolution change event

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

 



This patchset adds a source_change event to the v4l2-events.
This can be used for notifying the userspace about runtime
format changes happening on video nodes / pads like resolution
change in video decoder.

This version includes suggestions from Hans and Laurent
to make it more generic and to be used by all kinds of
video devices to notify userspace about runtime parameter
changes. The discussion can be seen here [1]

If this is accepted, I can send another series implementing
v4l2_event_init() for zeoring the data array addressing
compatibility issues as discussed in [1].
