2020-09-12qcam: format_converter: Support R8 GreyscaleKieran Bingham
Support Greyscale images in the format converter by expanding the R8 component to each of the output RGB components.

2020-06-18qcam: Replace explicit DRM FourCCs with libcamera formatsLaurent Pinchart
Use the new pixel format constants to replace usage of macros from drm_fourcc.h. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>
2020-03-24qcam: Use QSize through the code baseLaurent Pinchart
Qt has a QSize class to store sizes. Use it to replace width and height where applicable. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
2020-03-24qcam: Ensure headers are self-containedLaurent Pinchart
Include the headers corresponding to each compile unit at the very first line to ensure they are self-contained. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
2020-03-18libcamera: PixelFormat: Mark all function arguments of type PixelFormat as ↵Niklas Söderlund
const reference PixelFormat was previously an alias for unsigned int but is now a class. Make all functions taking PixelFormat do so as a const reference. Signed-off-by: Niklas Söderlund <niklas.soderlund@ragnatech.se> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-03-18libcamera: pixelformats: include linux/drm_fourcc.hNiklas Söderlund
Instead of having to include linux/drm_fourcc.h everywhere a DRM FourCC is used in conjunction with PixelFormat include the header directly in pixelformats.h. Signed-off-by: Niklas Söderlund <niklas.soderlund@ragnatech.se> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-03-18libcamera: Use PixelFormat instead of unsigned int where appropriateNiklas Söderlund
Use the PixelFormat instead of unsigned int where a pixel format is to be used. PixelFormat is defined as an unsigned int but is about to be turned into a class to add functionality. There is no functional change in this patch. Signed-off-by: Niklas Söderlund <niklas.soderlund@ragnatech.se> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-03-16qcam: format_convertor: Extend 32 bit ARGB format combinationsKieran Bingham
Add further support to the pixel format convertor to allow ARGB, RGBA, and ABGR formats to be displayed in qcam. Blank lines are added between the sections for NV, RGB, YUV, and MJPEG configurations. The implementation of the RGB conversions are highly inefficient, and where possible should be extended to use hardware accelerations such as OpenGL, or in the event that the input format is identical (or compatible) with the output format - a more optimised memcpy should be implemented.

2019-05-07qcam: format_converter: Add formatFamily enumPaul Elder
It is not sustainable to add a new flag for every new video format family (eg. YUYV, RGB, NV, MJPEG, etc), so add a formatFamily enum to indicate these in the FormatConverter. Note that formats are grouped into families based on if they are able to share a set of parameters for conversion.

2019-03-29qcam: Add Qt-based GUI applicationLaurent Pinchart
qcam is a sample camera GUI application based on Qt. It demonstrates integration of the Qt event loop with libcamera. The application lets the user select a camera through the GUI, and then captures a single stream from the camera and displays it in a window. Only streams in YUYV formats are supported for now.
