I'd say None, since that's something a renderer would do, not a decoder. SVP, which does what you're asking for, just had a very successful fundraiser. Watch for a totally re-written v.4 later this year or early next year.

I believe all of the frame interpolation techniques at the moment rely on recreating motion vectors from the raw image data, once it has been decoded, which is much less efficient: it's basically decoding the data, re-encoding the data and then decoding again as I suggested. Decoders are code optimised to be very fast, whereas most of the techniques use a higher level programming which is not very efficient. Unfortunately there wouldn't be many people capable of creating a new decoder. |

Motion interpolation and optimal compression are completely different, and therefore the vectors shouldn't be shared. The exact same discussion was had for MVTools for Avisynth, and it turned out that while good coherent motion vectors are available in some blocks, mostly they're a ways off -- or even completely backward -- anywhere that it saves bits. A stream analyzer like CodecVisa will reveal just how crazy they're stored.

Have you checked with GPU-Z that it doesn't? Intel has a hybrid decoder now, and the results are good, but it can only do so much. And if it's 10-bit UHD, GPU can't handle it at all. Alternately, perhaps your drivers are way out of date.
Otherwise, you're just pushing your system beyond what it can handle. Last edited by foxyshadis; 8th September 2015 at 07:50. |

It is 10bit and CPU is too slow. So it wont play smooth anyway.
All you can try is a 64Bit Player with 64bit LAV. In DVBViewer the renderer skips late frames (can be changed in settings) and that's why it seems to hang? |

and he is watching broadcast so it should be 10 bit HEVC with 20 to 60 MBIT. so you kind of need an gtx 950/960 to play it. |

P.J says yes, but I want that someone say yes too (especially you, huhn, nevcairiel, Aleksoid1978...), because foxyshadis writed some posts upper: "if it's 10-bit UHD, GPU can't handle it at all". Quote:

There is no GPU to actually decode in pure fixed-function HW 10bit H.264 clips, but Nvidia 950 & 960 can really decode in HW 10bit H.265 clips. Nowadays there are only those two pure 10bit HW decoders, but next - gen Intel iGPUs and AMD GPUs which can already decode 8bit H.265 in HW, they will add 10bit too.

Because most of UHD from SATs are 10bit (and this is problem for Elecard HEVC Video Decoder which shows recorded UHD h265 10bit 4:2:0 well in i.e. MPC-HC (but UHD in KMP 3.9.1.135 hangs up, SD and HD h265 works perfect) with i.e. LAVsplitter, but in SAT programs (DVBViewer, ProgDVB x86 and x64 and DVBDream) it shows color abracadabra ((( |
