[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
Specifies the video mode of operation for a video device.
Specifies that the picture is flipped horizontally.
Specifies that the picture is flipped vertically.
Sets up a stream to capture a trigger from an external source, for example, a push button on a camera. Buffers can be queued to the driver but will not be passed up from the WDM capture driver (for compression, display, or writing to a file) until the external event happens. See Remarks.
In software, simulates an external trigger when the stream has the VideoControlFlag_ExternalTriggerEnable flag set.
The IAMVideoControl interface uses this enumerated data type.
Multiple capture buffers are queued to a capture driver and are filled at a fixed rate once the stream is put into the "run" state. If the VideoControlFlag_ExternalTriggerEnable flag is set, a filled buffer is not passed up from the WDM capture driver for compression, display, or writing to a file until the external event happens.
