Before this change if StillCapture was not requested first it got assigned to the self-path and thus down-scaled to 1920x1920. With this change, StillCapture can be asked last and it would take precedence over other streams for the usage of the main path. $ cam -c1 --stream role=viewfinder --stream role=still Camera camera.cpp:969 streams configuration: (0) 1920x1080-NV12 (1) 4208x3120-NV12 Signed-off-by: Jacopo Mondi --- src/libcamera/pipeline/rkisp1/rkisp1.cpp | 15 ++++++++++++++- 1 file changed, 14 insertions(+), 1 deletion(-) diff --git a/src/libcamera/pipeline/rkisp1/rkisp1.cpp b/src/libcamera/pipeline/rkisp1/rkisp1.cpp index 05a7ba03b2d2..23ff859e3835 100644 --- a/src/libcamera/pipeline/rkisp1/rkisp1.cpp +++ b/src/libcamera/pipeline/rkisp1/rkisp1.cpp @@ -626,6 +626,16 @@ PipelineHandlerRkISP1::generateConfiguration(Camera *camera, if (roles.empty()) return config; + /* If still capture is requested, reserve the main path for it. */ + bool reserveMainPath = false; + for (const StreamRole role : roles) { + if (role != StreamRole::StillCapture) + continue; + + reserveMainPath = true; + break; + } + /* * As the ISP can't output different color spaces for the main and self * path, pick a sensible default color space based on the role of the @@ -644,6 +654,9 @@ PipelineHandlerRkISP1::generateConfiguration(Camera *camera, if (!colorSpace) colorSpace = ColorSpace::Sycc; + /* Unlock usage of main path which was reserved. */ + reserveMainPath = false; + size = data->sensor_->resolution(); break; @@ -685,7 +698,7 @@ PipelineHandlerRkISP1::generateConfiguration(Camera *camera, RkISP1Path *path; - if (useMainPath) { + if (useMainPath && !reserveMainPath) { path = data->mainPath_; mainPathAvailable = false; } else {
