The "get_title()" function in my program is responsible for getting video title. It is used in a loop to return titles of 5 previous tracks, currently played track and 5 tracks after it. Loop is run each time a new track starts to play. The code bellow is written for testing purposes so you could easily check the problem on your PC if you desire so.

// main.cpp
std::string get_title(
std::string song_mrl
)
{
const char *const arg[] = {"--preferred-resolution=720", "--no-video"};
std::shared_ptr<VLC::Instance> dummy = std::make_shared<VLC::Instance>(VLC::Instance(2, arg));
VLC::Media media = VLC::Media(*dummy, song_mrl, VLC::Media::FromLocation);
media.parseWithOptions(VLC::Media::ParseFlags::Network, -1);
while (media.parsedStatus() != VLC::Media::ParsedStatus::Done) { }
return media.subitems()->itemAtIndex(0)->meta(libvlc_meta_Title);
}

std::cout << get_title(mrls[2]) << std::endl;
std::cout << std::endl;
