多个 AVPlayer 添加到 this->scene()->addWidget(z->m_renderer->widget());

多个 AVPlayer + OpenGLWidgetRenderer 时，结束一个另外的也会被结束掉 ...

    VideoRenderer* renderer = z->m_avplayer->renderer();
    if (renderer->widget()) {
        renderer->widget()->close(); //TODO: rename
        if (!renderer->widget()->testAttribute(Qt::WA_DeleteOnClose) && !renderer->widget()->parent())
            delete renderer;
    }

需要delete么？

[nulijiabei]

@wang-bin 需要 ... scene 同一个层需要使用不同的 QWidget ，AVPlayer 只是其中之一 ...

不过上下文都是 AVPlayer 则不 Delete ... 如果不是则需要 Delete ... 不释放一般 20分钟 就 Crash 了

[nulijiabei]

@wang-bin 看看有什么办法，只释放当前的 AVPlayer ... 而不是所有 ...

如果把每个 AVPlayer 都保存下来 ... 通过各种标记来实现反复使用 ... 下下策有点 ...

[wang-bin]

delete renderer前不用removeWidget之类的操作？

[nulijiabei]

@wang-bin 当然会 this->scene()->removeItem ...

@wang-bin 没能理解您的想法？您是说移除 this->scene()->removeItem 后不要 delete renderer ?

[nulijiabei]

createDIB: CreateDIBSection failed.

[nulijiabei]

搞不定啊 ... 多个 QtAV::AVPlayer 如果不 renderer->widget()->close(); 一会儿就 createDIB: CreateDIBSection failed. 如果 close(); 只要一 close(); 另外一个 QtAV::AVPlayer 的 renderer 就不显示了 ...

[wang-bin]

你试试不用graphicsview

[nulijiabei]

@wang-bin 不用 graphicsview 貌似没事 ...
