[libcamera-devel] [PATCH v4 0/6] libcamera: add basic support for streams and format configuration

[Niklas Söderlund]

Hi,

This series aims to add support of Streams to the Camera object. A
Stream is a single video stream origination from a video source,
multiple video streams might form the same Camera is possible as long as
they all originate from the same video source.

Biggest change from v3 is that the stream ids are gone and the new key 
to identify streams are a Stream*. To allow pipeline handlers to still 
map a incoming configuration a stream the ownership of the Stream 
objects are moved from the Camera object to the pipeline handlers.
