Is there any chance of getting HW accelerated deinterlacing for h264 in future?

Hi MrMC Devs,

I'm a really happy user of the FireTV 2 and MrMC on it, and since the last version, playback start speed, and hardware accelerated playback works really well, I'm really impressed and that's achieved on an 100MBit Network Adapter - wow :) My Wetek Hub with Gigabit Ethernet is way slower starting and skipping the videos :)
So thanks a lot for that 1st :)

But now to my question: I'm waiting since long time if there will some some good quality h264 1080i deinterlacer on the Fire TV 2. Something like that one on the Wetek Hub (Advanced Motion Adaptive Deinterlacer) or an NEON code accelerated yadif 2x deinterlacer. Is something like that in sight in near future?

Just asking, cause if not, I'm considering updating my Server CPU and Motherboard to transcode Live TV to 720p (tvheadend on xpenology) before sending it to the Fire TV. Would rather not do that if you can maybe already say that something like is in the works.

Thanks for your hard work and that awesome support here :)

Regards
Vlaves

Nope, what you see is what you get :)

The FireTV (either flavors) just does not have the ponies for yadif. I can look and see what Wetek Hub is doing but I bet a dollar that it is custom to their firmware (amlogic based).

There are a few things you can try. MediaCodec(surface) uses the internal mediacodec deinterlacer for surface. MediaCodec(non-surface) uses our deinterlacers. That's why there is a settings to disable MediaCodec(both) for interlaced content.

And software (FFMpeg) uses ours and FFMpegs. Only under FFMpeg will you be able to select yadif. Maybe ok for SD content but HD content will skip and stutter as there are just not enough ponies to do both decode and deinterlace.

Thanks for the fast and clear answer :) No need to check, they are utilizing the hardware specifik amlogic deinterlacer.
But at least now I know, no need to wait...Time for a new board and CPU :)
