Member Function Documentation

bool pangolin::FfmpegVideo::GrabNewest	(	unsigned char *	image,
		bool	wait = `true`
	)		`[virtual]`

Copy the newest frame from the camera to image discarding all older frames. Optionally wait for a frame if one isn't ready Returns true iff image was copied

Implements pangolin::VideoInterface.

bool pangolin::FfmpegVideo::GrabNext	(	unsigned char *	image,
		bool	wait = `true`
	)		`[virtual]`

Copy the next frame from the camera to image. Optionally wait for a frame if one isn't ready Returns true iff image was copied

Implements pangolin::VideoInterface.
