C++ (Cpp) ReadFrames Examples

Example #1

File: MediaBlockMap.cpp Project: Barrett17/Faber

int64
MediaBlockMapReader::ReadFramesAt(void* buffer, int64 start, int64 frameCount)
{
    if (start < 0)
        return 0;

    SeekToFrame(start);
    return ReadFrames(buffer, frameCount);
}

Example #2

File: matching_dlg.cpp Project: mvancompernolle/ai_project

bool CMatchingDlg::SelectFrame(int *frame_id)
{
	m_FrameID = 0;

	gtk_widget_hide(m_UseFrame);
	ReadFrames(true, *frame_id);
	SetSelectMode(REFERENCE_FRAME);
	SetSortMode(m_FrameSort);
	UpdatePreview(true);
