The translation is shorter. "پخش روان" is more suitable than "پخش پیوسته" as said in the translation for "streaming" like "streaming water" that becomes "آب روان".
Regardless of the technical similarities, the text suggests that you "may need to" not that you "should" download it, so, "باید" that means "should" or "have to" should be replaced with "ممکن است".
Finally, we can localize "دانلود" that is the transliteration of "download" to "بارگیری".

Persian equivalent for "Streaming" is "پخش زنده آنلاین". In case of telegram videos as they're not livestreamed, I deleted the word "زنده" and used "پخش آنلاین" which I think is the most accurate translation and is also easy to understand for the general public.
