C++ (Cpp) DiscardFrames Examples

Example #1

void VideoOutputOpenGL::TearDown(void)
{
    QMutexLocker locker(&gl_context_lock);

    DiscardFrames(true);
    vbuffers.DeleteBuffers();
    vbuffers.Reset();

    if (av_pause_frame.buf)
    {
        delete [] av_pause_frame.buf;
        av_pause_frame.buf = NULL;
    }
    if (av_pause_frame.qscale_table)
    {
        delete [] av_pause_frame.qscale_table;
        av_pause_frame.qscale_table = NULL;
    }

    if (gl_context)
        gl_context->makeCurrent();

    if (gl_videochain)
    {
        delete gl_videochain;
        gl_videochain = NULL;
    }

    if (gl_created_painter)
        delete gl_painter;
    else
        gl_painter->SetSwapControl(true);

    gl_painter = NULL;
    gl_created_painter = false;

    while (!gl_pipchains.empty())
    {
        delete *gl_pipchains.begin();
        gl_pipchains.erase(gl_pipchains.begin());
    }
    gl_pip_ready.clear();

    if (gl_context)
        gl_context->doneCurrent();
}
