L1723 in Source/WebCore/page/Page.cpp:


```
void Page::stopAllMediaPlayback()
{
    for (Frame* frame = &mainFrame(); frame; frame = frame->tree().traverseNext()) {
        if (auto* document = frame->document())
            document->stopAllMediaPlayback();  <<<<<<<<<
    }
}   
```

But those functions are only enabled with VIDEO flag ON, L1706 in Source/WebCore/dom/Document.cpp:

```
#if ENABLE(VIDEO)
void Page::stopAllMediaPlayback()

void Page::suspendAllMediaPlayback()

void Page::resumeAllMediaPlayback()
#endif
```
