示例1: unloadVideo
void MediaServer::unloadVideo(string& path) {
VideoSource* videoSource = static_cast<VideoSource*>(getSourceByPath(path));
// Decrease reference count of the video
//referenceCount[path]--;
videoSource->referenceCount--;
// Unload only if reference count is less or equal to 0
if (videoSource->referenceCount > 0) {
ofLogNotice("MediaServer") << "Not unloading video as it is being referenced elsewhere";
return;
}
// Reference count 0 or less, let's unload the video
ofLogNotice("MediaServer") << "Removing video " << path;
// Distroy video source
if (loadedSources.count(path)) {
ofLogNotice("MediaServer") << "Source count before video removal: " << loadedSources.size() << endl;
videoSource->clear();
std::map<std::string, BaseSource*>::iterator it = loadedSources.find(path);
delete it->second;
loadedSources.erase(it);
ofLogNotice("MediaServer") << "Source count after video removal: " << loadedSources.size() << endl;
ofNotifyEvent(onVideoUnloaded, path, this);
return;
}
// Something wrong here, we should be out of the routine by now
std::stringstream failss;
failss << "Failed to remove video source: " << path;
