This extends qcam to accept role hints and pixel\nformat in addition to a size.\n\nCurrently only one viewfinder stream is supported, add a check to keep\nthis behavior. Going forward this restriction will be lifted to support\nmore then one stream.\n\nSigned-off-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>\n---\n src/qcam/main.cpp        | 12 ++++--------\n src/qcam/main_window.cpp | 35 ++++++++++++++++++-----------------\n src/qcam/main_window.h   |  4 ++--\n src/qcam/meson.build     |  1 +\n 4 files changed, 25 insertions(+), 27 deletions(-)",
