From 4814d8f1b5b397137da5efedd9a5b4351cbfe836 Mon Sep 17 00:00:00 2001 From: Jacopo Mondi Date: Thu, 19 Oct 2023 16:01:33 +0200 Subject: py: cam: Add option to set stream orientation Add a '--orientation|-o' option to the Python version of the cam test application to set an orientation to the image stream. Supported values are: - rot0: no rotation - rot180: rotate 180 degrees - flip: vertical flip - mirror: horizontal flip Signed-off-by: Jacopo Mondi Reviewed-by: Laurent Pinchart Signed-off-by: Laurent Pinchart --- src/py/cam/cam.py | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) (limited to 'src/py/cam') diff --git a/src/py/cam/cam.py b/src/py/cam/cam.py index a2a115c1..ff4b7f66 100755 --- a/src/py/cam/cam.py +++ b/src/py/cam/cam.py @@ -23,6 +23,7 @@ class CameraContext: opt_metadata: bool opt_save_frames: bool opt_capture: int + opt_orientation: str stream_names: dict[libcam.Stream, str] streams: list[libcam.Stream] @@ -146,6 +147,21 @@ class CameraContext: if 'pixelformat' in stream_opts: stream_config.pixel_format = libcam.PixelFormat(stream_opts['pixelformat']) + if self.opt_orientation is not None: + orientation_map = { + 'rot0': libcam.Orientation.Rotate0, + 'rot180': libcam.Orientation.Rotate180, + 'mirror': libcam.Orientation.Rotate0Mirror, + 'flip': libcam.Orientation.Rotate180Mirror, + } + + orient = orientation_map.get(self.opt_orientation, None) + if orient is None: + print('Bad orientation: ', self.opt_orientation) + sys.exit(-1) + + camconfig.orientation = orient + stat = camconfig.validate() if stat == libcam.CameraConfiguration.Status.Invalid: @@ -385,6 +401,7 @@ def main(): parser.add_argument('--metadata', nargs=0, type=bool, action=CustomAction, help='Print the metadata for completed requests') parser.add_argument('--strict-formats', type=bool, nargs=0, action=CustomAction, help='Do not allow requested stream format(s) to be adjusted') parser.add_argument('-s', '--stream', nargs='+', action=CustomAction) + parser.add_argument('-o', '--orientation', help='Desired image orientation (rot0, rot180, mirror, flip)') args = parser.parse_args() cm = libcam.CameraManager.singleton() @@ -408,6 +425,7 @@ def main(): ctx.opt_metadata = args.metadata.get(cam_idx, False) ctx.opt_strict_formats = args.strict_formats.get(cam_idx, False) ctx.opt_stream = args.stream.get(cam_idx, ['role=viewfinder']) + ctx.opt_orientation = args.orientation contexts.append(ctx) for ctx in contexts: -- cgit v1.2.1
