[libcamera-devel] [PATCH 0/7] libcamera: Map multiple V4L2 formats to a single libcamera::format

[Pavel Machek]

Hi!

> This series addresses the requirement of mapping multiple V4L2 pixel formats
> to a single libcamera format. Specifically, it allows to map V4L2_PIX_FMT_JPEG
> and V4L2_PIX_FMT_MJPEG to libcamera::formats::MJPEG.
> 
> The series starts by allowing to associate mulitple V4L2 FourCC in
> PixelFormatInfo and re-introduces toV4L2PixelFormat() in V4L2VideoDevice in
> order to select among from the list of V4L2 formats the first one supported
> from the video device.
> 
> Patch [7/8] adds a multiplanar flag to V4L2VideoDevice::toV4L2PixelFormat() to
> allow selection of the contiguous or non-contiguous format versions.
> 
> Finally, the last patch associates V4L2_PIX_FMT_JPEG to formats::MJPEG.

> Tested with a UVC camera.

I tried to do quick testing, but it is not trivial as I have to patch
libcamera to get it work on PinePhone at all. I could not get it to
work so far.
