AML can software decode some 720/1080p Hi10P but there are still to many problems when tested with more than a single video sample. Its not reliable at all.
You really do need proper Intel Hardware.

Where H264 and older get blocky, H265 gets fuzzy with low bitrates. This is the worst case for anime encoding because you see it more prominent there. If you have high enough bitrates, the file sizes are only slightly smaller than H264, at the price of 5x - 10x slower encode.(2016-05-23, 14:10)noggin Wrote: H264 Hi10 4:2:0 is a dead-end codec. It's never got hardware acceleration support (a Rockchip SoC was rumoured to have hardware support - but Rockchip Linux support is lousy), and so the only real solution is CPU decode - which really means a decent x86 platform at the moment.
Hopefully the perceived benefit of H264 Hi10 (reducing banding on Anime re-encodes AIUI?) will transfer to H265 10 bit so that is used instead - which DOES have hardware SoC support (AML S905 does it for instance) in the future. We could then finally stop having to answer the same questions. Again. And Again. And Again.
Where I'm at a loss is as to how this hasn't happened yet. Some in the anime scene want the leanest and meanest compression, which is why it's really the only scene you see Hi10 in use. With HEVC/x265 available readily, why have a good number no jumped to that ship already?

No Hardware decoder on any hardware platform supports Hi10P and that says it all really.

First of all, Hi10 does see usage outside of the 'Anime World', though it's almost exclusively in the realm of prosumer and professional level video recorders for various kinds of film production. Film production routinely see's hardware capable of capturing images beyond 8 bits per channel that we typically see in consumer products. This is where a compressed 10bit storage format gets usage. This is of course specialized hardware and no where else do you see 10bit. It was never seen in any disc media or any streaming media, which is the exact media that low cost hardware decoding chips are designed for. They are built to decode consumer video on consumer products. Adding features beyond what is needed, for a super niche area of content, makes no financial sense and this is why you see no hardware companies bothering to embrace it. 10bit is not 'shunned by the rest of the world', it just doesn't make any financial sense to build hardware for a narrow region of a format that only see's usage in some pro hardware and on pirated anime.
