I think that's right. I quoted the YU12/YM12 example, but we have the same thing with NV12 contiguous/non-contiguous and probably a few others as well. > > > > > > > Instead, ignore the V4l2 format if the pixel format has already been > > > seen. > > > > > > Signed-off-by: David Plowman <david.plowman@raspberrypi.com> > > > > Reviewed-by: Naushir Patuck <naush@raspberrypi.com> > > > > > > --- > > > src/libcamera/pipeline/rpi/common/pipeline_base.cpp | 6 +++++- > > > 1 file changed, 5 insertions(+), 1 deletion(-) > > > > > > diff --git a/src/libcamera/pipeline/rpi/common/pipeline_base.cpp b/src/libcamera/pipeline/rpi/common/pipeline_base.cpp > > > index 7e420b3f..0034e06d 100644 > > > --- a/src/libcamera/pipeline/rpi/common/pipeline_base.cpp > > > +++ b/src/libcamera/pipeline/rpi/common/pipeline_base.cpp > > > @@ -474,7 +474,11 @@ PipelineHandlerBase::generateConfiguration(Camera *camera, Span<const StreamRole > > > */ > > > for (const auto &format : fmts) { > > > PixelFormat pf = format.first.toPixelFormat(); > > > - if (pf.isValid()) { > > > + /* > > > + * Some V4L2 formats translate to the same pixel format (e.g. YU12, YM12 > > > + * both give YUV420).

But for "are there none?" of course it's fine! Thanks!

Some V4L2 formats translate to the same pixel format, e.g. YU12 and YM12 both produce YUV420. In this case our ISP driver advertises the same size range for both, but we must not record the same thing twice for the same pixel format (which will cause a failure later on). Instead, ignore the V4l2 format if the pixel format has already been seen.
