Subject: [PATCH 15/31] camerabin2: Support setting default filters
|
|
Use env "CAMERABIN2_PREVIEW_FILTER", "CAMERABIN2_IMAGE_FILTER",
|
"CAMERABIN2_VIDEO_FILTER", "CAMERABIN2_VIEWFINDER_FILTER" to set default
|
filters.
|
|
Tested with:
|
export CAMERABIN2_VIEWFINDER_FILTER="videoflip method=clockwise"
|
gst-launch-1.0 camerabin
