[libcamera-devel] [PATCH v3 11/22] libcamera: pipeline: rkisp1: Configure self path
Niklas Söderlund
niklas.soderlund at ragnatech.se
Fri Sep 25 03:41:56 CEST 2020
Allow for both the main and self path streams to be configured. This
change adds the self path as an internal stream to the pipeline handler.
It is not exposed as a Camera stream so it can not yet be used.
Signed-off-by: Niklas Söderlund <niklas.soderlund at ragnatech.se>
---
* Changes since v2
- Print which resizer is configured
- Use if ...; else if; ... instead of if ...; if ...; in
exportFrameBuffers()
- Configure main and self streams with separate numbers of buffers while
still allocating the max of the two for stats and params.
- Improve Warning logs in stop()`
