◆ Finish()

void cSoftHdGrab::Finish ( void )

Clean up.

Clears the dedicated buffers in the renderer again and sets the grab inactive.

Convert the cloned drm buffer data to RGB(void, pip) or ARGB (osd) and return a pointer to the raw data.

Parameters

[out]	size	size of the grabbed buffer
[out]	width	width of the grabbed buffer
[out]	height	height of the grabbed buffer
[out]	x	x offset of the grabbed buffer
[out]	y	y offset of the grabbed buffer
[in]	grab	grabbed buffer

Returns: a pointer to the raw buffer data

◆ ProcessGrab()

bool cSoftHdGrab::ProcessGrab ( void )

Start the conversion.

This does the following: 1) Get grabbed video data if available, otherwise create a black screen for video 2) Get grabbed pip data if available 3) Get grabbed osd data if available 4) Blit the video data into a black background image if it is scaled 5) If available, blit the pip data onto it 6) If available, blit the osd data onto it respecting alpha values 7) Scale the result to the user requested size 8) Create a jpg or pnm image as requested

Returns: true, if grab succeeded, false otherwise
