輸入是 Bayer  才能使用 nvarguscamerasrc .. 可以使用內部ISP

Applications Using GStreamer with the nvarguscamerasrc Plugin


 

JetsonTX2/NVIDIA Jetson ISP Control

輸入是 YUV   則使用 v4l2src  , 不會經過NV內部ISP

不過NV有參數 nvvidconv 可以帶入做些影像處理 , 詳細內容可以 gst-inspect-1.0 nvvidconv 去查

如: nvvidconv flip-method=4

  flip-method         : video flip methods
                        flags: readable, writable, controllable
                        Enum "GstNvVideoFlipMethod" Default: 0, "none"
                           (0): none             - Identity (no rotation)
                           (1): counterclockwise - Rotate counter-clockwise 90 degrees
                           (2): rotate-180       - Rotate 180 degrees
                           (3): clockwise        - Rotate clockwise 90 degrees
                           (4): horizontal-flip  - Flip horizontally
                           (5): upper-right-diagonal - Flip across upper right/lower left diagonal
                           (6): vertical-flip    - Flip vertically
                           (7): upper-left-diagonal - Flip across upper left/lower right diagonal

若沒有實際影像輸入 可以用 videotestsrc  做測試

 gst-launch-1.0 videotestsrc ! videobalance hue=1.0 saturation=0.0 contrast=1.5 brightness=-0.3  ! videoconvert ! ximagesink

 gst-launch-1.0 videotestsrc ! videoflip method=clockwise ! videoconvert ! ximagesink
