Hi,

Thanks

DXVA2 copy-back + GTX960: UHD 4K 10 BITS ASTRA/EUTELSAT

it's work only with latest LAV 0.64.52 build (16/04/2015)
(ok with enhanced video renderer or madvr)
(files froms nightly MPC-HC)

Still not ok with DXVA2 NAtive, but it's better. (20% CPU)

You can report it to NVIDIA and hope they improve it.

Gotcha.

I've discovered madVR has now a 64 bits. What about dts-hd decoder ? Do you know if there's something being worked to have a 64 bits dts-hd decoder ?
I remember once reading there were a "beginning" on ffmpeg project.

get the lavfilter nightly.

DXVA2 Native does not support 10-bit, and thats very unlikely to change.

[pirlouy]

I searched through the commits and I finally ended on dcadec.

Is it working well for classic DTS-HD from Blu-Ray ? If yes, that's great, and I'll wait for final LAV builds to test this 64 bits.

Don't get why you don't just install it and test it for yourself... But yes it works fine.

Why wait for final? Nev's master builds are as stable as anything final.

CUVID was very important before DXVA was a "thing". since DXVA it is kind of superseded.
at the moment CUVID just wastes power by forcing the GPU in highest powerstate.

Thanks for your thoughts on the matter,

No, it did not. Currently, the only nVidia GPU that has VDPAU feature set F support in hardware is GM206, which is used in GeForce GTX 960.

Is LAV dithering has similar algorithm as provided in madVR?

No, madVR uses higher quality dithering. LAV's dithering will never be used when rendering with madVR and using LAV's default settings.

LAV Filters 0.65

LAV Splitter
- NEW: Support for MKV subtitle Cues to show subtitles immediately after a seek
- NEW: Attachments and embedded cover art images are exported through the IDSMResourceBag interface
- Fixed: Improved demuxing of HEVC in MPEG-TS and increased the reliability of the SPS/PPS/VPS extraction
- Fixed: Demuxing Blu-rays/MPEG-TS where the first stream was not a video stream could result in broken timestamps
- Fixed: Seeking in MKVs which are currently being written is more reliable

LAV Video
- Fixed: Improved HEVC DXVA2 decoding on a few samples
- Fixed: Playback of VFR MPEG-4 in AVI had wrong timestamps in 0.64
- Fixed: Improved handling of DVD subtitles without timestamps

LAV Audio:
- NEW: Native DTS-HD decoding using libdcadec
- Changed: 5.1 audio prefers the speaker mask with side channels, to match recent specifications

Download: Installer (both x86/x64) -- Zips: 32-bit & 64-bit

DTS-HD decoding support through libdcadec

LAV Audio now includes libdcadec, a full-featured DTS-HD decoder.
All known DTS-HD MA and DTS-HD HRA samples are supported and decoded perfectly lossless, up to 7.1, 192kHz, 24-bit (with a possible exception in a few weird samples). In addition, it also supports a long list of core extensions, including XCH (for 6.1 DTS ES streams), and X96 (for DTS 96/24).

The only unsupported DTS format that I know of is DTS Express, which is used for interactive commentary tracks on Blu-rays.

If the ArcSoft decoder is present, it will continue to be used for the time being, but in the long run I may even remove it.

If you find anything that doesn't seem to behave properly with the new DTS decoder, please do report and I'll work with the libdcadec author to see what is going on!

------

I wanted to get some more features done for this release, but time was short, and it felt like this was worth releasing anyway, so, have fun with it!

[kalston]

Nice! Btw in the original post next to the dl link for the installer it still says 0.64 (even though the link does point to 0.65)

[ddjmagic]

Thanks for the new release!

[Bozotheclown]

in audio properties -> formats -> in libdcadec section should be add (DTS, DTS-HD, DTS-HR, etc.) like in ac3?
I mean common used codec name

[rd1979]

This is a big release to me, even if it doesn't have everything you wanted in it, a lot of longstanding little niggling issues I had are addressed here.
Thanks nev!

when i choose mpc-hc audio renderer @ sound device choose speaker (realtek ALC892) the sound is good but whenever i adjust the seekbar got the distortion & shuttering sound from any videos.

[nevcairiel]

MPC-HC Audio Renderer is not recommended to be used at this point, but thats more of a topic for the MPC-HC thread.
