Where can I watch Perariyathavar?

And films like those. Ever since Venjaramoodu won that award for it, I have been meaning to watch it. But neither did it release where I live nor do I see it on DVDs or streaming services.

Does anyone have any clue about it and other movies like Oralpokkam, Kunju Daivam, Kaadu Pookkunna Neram, Karutha Joothan, Jalam, Maanasaandarapetta Yezdi , Lens, Njan Ninnodu Koodeyundu, Unto the Dusk, Karma Cartel, and Ottal?
