[mythtv-users] H265 support?

Support for a card like this would be nice to offload from the CPU the H265 encoding

but I'm not sure your problem is big enough to justify the $

I am just wondering if we have support to play H265 videos?

Support for HEVC landed in FFmpeg after we did the last sync, so not yet.

THank you. Will wait for the next sync. I have a couple movies and would love to see the smaller yet hopefully better videos.

Just as H264 is vastly more intensive than H262 (MPEG2) before it, H265 is vastly more intensive than H264.  A 3.5GHz quad-core Haswell manages around 1fps on 1080p content.  It's cheaper to just buy the extra hard drive space than to buy the electricity to run x265.  Unless you're constrained on space by some portable device, or on throughput trying to stream over the internet, there's no reason to be using H265 at this time.
