These Smart TVs are very locked down. This is why you transcode video to play on such TVs.
I've used Handbrake and VLC Player to do such work.
I own a Sony 32 inch klv-r302e TV which allows playing MPEG4, H.264 codec encoded files. But it does n't support HEVC H.265 playback. Is there a way to install this codec on this TV by cracking the software or some other way? (like someone can install a new OS in a smart phone by rooting)
(I understand that HEVC playback needs good hardware. But I should be able to play up to some level with the available processing power. at least 1080p videos)
