|
Close the video input device on destruction. |
|
Is the device a camera, and obtain video Implements PVideoDevice. |
|
Close the device. Implements PVideoDevice. Reimplemented in PVideoInput1394DcDevice. |
|
Create the video input device that corresponds to the specified driver name.
|
|
|
|
Create an opened video input device that corresponds to the specified names. If the driverName parameter is an empty string or "*" then CreateDeviceByName is used with the deviceName parameter which is assumed to be a value returned from GetDriversDeviceNames().
|
|
Get the list of available video input drivers (plug-ins)
|
|
Get video input devices that correspond to the specified driver name. If driverName is an empty string or the value "*" then this will return a list of unique device names across all of the available drivers. If two drivers have identical names for devices, then the string returned will be of the form driver+''+device.

|
Grab a frame. |
|
Grab a frame, after a delay as specified by the frame rate.
Implemented in PVideoInput1394DcDevice. |
|
Grab a frame. Do not delay according to the current frame rate parameter.
Implemented in PVideoInput1394DcDevice. |
|
Determine if the video device I/O capture is in progress. Implemented in PVideoInput1394DcDevice. |
|
Open the device given the device name.
Implements PVideoDevice. Implemented in PVideoInput1394DcDevice. |
|
Try all known video formats & see which ones are accepted by the video driver Implemented in PVideoInput1394DcDevice. |
