First, "Greyhound" could be a movie title, like the 2020 film with Chris Evans and Ana de Armas. The numbers "2020720" might indicate the year and resolution—720p usually refers to the resolution, so maybe it's a 2020 release in 720p quality. "PHDRI" is a bit confusing. HDR typically stands for High Dynamic Range, a video quality feature, but PHDRI? Could it be a typo or a specific codec? Maybe the user meant HDR. "PHINDIDUB" might split into "PHINDI" and "DUB"—PHINDI could be an Indian movie, like the 2020 Telugu film "Padi Padi Leche Manasu," but that's just a guess. DUB means dubbed audio. "DUALAUDIO" probably means it has two audio tracks, like the original and a dubbed version. "Portable" suggests it's a downloadable file or software that's easy to carry or use on the go.
