示例1: GetFrameForDecoding
VideoFrame* VideoBuffers::GetFrameForDecoding(void)
{
VideoFrame *frame = NULL;
{
QMutexLocker locker(m_lock);
// create new frame if still below limit
if (m_frameCount < (m_referenceFrames + m_displayFrames))
{
frame = new VideoFrame(m_preferredDisplayFormat);
frame->Initialise(m_currentFormat, m_currentWidth, m_currentHeight);
m_frameCount++;
m_decoding.append(frame);
return frame;
}
// return unused frame if available
if (!m_unused.isEmpty())
{
frame = m_unused.takeFirst();
