gf_vcap_set_flags()

Set video capture flags

Synopsis:

#include <gf/gf.h>

void gf_vcap_set_flags ( gf_vcap_t      vcap,
                         unsigned       flags );

Arguments:

vcap

The handle of the video capture unit, returned by gf_vcap_attach().

flags

Flags controlling capture behavior. Valid flags are:

GF_VCAP_FLAG_DEINTERLACE_BOB

Perform “BOB” deinterlacing. Each field is captured and displayed independently. The displayed frame alternates between odd and even fields.

GF_VCAP_FLAG_DEINTERLACE_WEAVE

Perform “WEAVE” deinterlacing. Scanlines from an odd and an even field are interleaved together to produce each displayed frame. The number of frames displayed by WEAVE deinterlacing is half the number displayed by BOB deinterlacing.

---

Upscaling is not supported when GF_VCAP_FLAG_DEINTERLACE_WEAVE is set.

---

 

GF_VCAP_FLAG_DEINTERLACE_ODD_ONLY

Only the odd fields are captured and displayed. The even fields are discarded.

Library:
