LAV Filters - DirectShow Media Splitter and Decoders

[madshi]

I hope that when Windows 10 RTM is released, everybody will finally upgrade their HTPCs, so we can get rid of XP. Well, I can dream, can't I? :)

[foxyshadis]

Good day.
I have a weak one core CPU Athlon 3200+ (with nVIDIA GT220) which can decode only 2-5 frames per second of h265 3840x2160p50 with LAVFilters-0.65.0.9-git х86 in WinXPx86.
Can you add possibility of choise which type of frames to decode like in ArcSoft Video Decoder (see attach)? Also add something like "If present decode IDR frames only else decode I frames only" please.
I want to hear audio and don't want to spend much time of watching slow motion h265 UltraHD video ;)

Better solution: Strip the audio and listen to it without the video. Win/win.

Is it that hard to come up with $50 to upgrade to something from the last 10 years?

[VictorLS]

My videocard is nVIDIA because they support XP much better then AMD. nVIDIA has CUDA so I can use hardware acceleration of MPEG2, h264, vc-1 under WinXP and Win7-10 with VideoMixingRenderer7 by LAV Video Decoder. nVIDIA already has 960 with hardware acceleration of h265. I will upgrade to 2-4 core AM2 - AM3 CPU to software decode h264 1080i50 4:2:2 from SATs and then buy chip nVIDIA videocard with h265 hardware acceleration to decode 2160p 4:2:0 from SATs.
PS. I don't like Win10. Win7 so so, Win 8.1 with upgrade not bad but often loose network (

Yesterday under Win10 I've found that Russian's Elecard HEVC decoder already has function to decode Key frames: Quality -> Skip non-key frames, but I can not to regsvr32 ehevcdec.ax under XP, hope yet.

Strongene_Lentoid_HEVC_Decoder_v2.0.3.3_2015_06_05_r4109 seems do not like files which begin with not key frame - it can not play files below.

Drop support for it, well help to get ppl upgrading :D

[VictorLS]

Drop support for it
I respect madshi and will use last version madvr which will work under XP :), basically for displaying real fps in top left corner by ctrl+j

[nevcairiel]

Personally, I'll definitely stop supporting XP at one point or another. It may not be today, it may not be this year, but it might be next year.

[VictorLS]

it might be next year.
Thanks.
I hope LAV Video Decoder will decode h265 with hardware acceleration at that time.

[foxyshadis]

Thanks.
I hope LAV Video Decoder will decode h265 with hardware acceleration at that time.

It already does.

[VictorLS]

It already does.
Under XP with nVIDIA 960? What drivers? CUVID or/and DXVA2 (native and/or copy back)?

[nevcairiel]

Under XP with nVIDIA 960? What drivers? CUVID or/and DXVA2 (native and/or copy back)?

It works both through DXVA2 and CUVID, if that works on XP .. I don't care, at all.

You should be happy that LAV works at all on XP, I will not spent a single minute worrying about extra features for XP.

Strongene_Lentoid_HEVC_Decoder_v2.0.3.3_2015_06_05_r4109 seems do not like files which begin with not key frame - it can not play files below.



Haven't tried Lentoid 2.0.3.3 yet, but 2.0.3.2 doesn't support 10 bit HEVC, so from the list of 7 clips, only two are 8bit and could possibly be decoded by Lentoid.

From those two clips, the "Service 1 (AAC).ts" plays just fine with both x64/x86 2.0.3.2 versions.

The other one is decoded only half (the upper half).

I tried also those two HEVC 8bit clips with HW decoding using Haswell and LAV 0.65.20.

LAV crashes in both files (due to driver incompatibility with the clips)

Cyberlink's PDVD 15 decoder handles those two files better with Haswell, falling back to SW decoding using both DXVA/ OpenCL HEVC decoding on the same system.

[VictorLS]

You should be happy that LAV works at all on XP
And I'm happy ...
2.0.3.2 doesn't support 10 bit HEVC
First of all - thank you.
So Lentoid not my h265 decoder yet :)
the "Service 1 (AAC).ts" plays just fine with both x64/x86 2.0.3.2 versions.
May be Lentoid like Haswell

[clsid]

Does CUVID only support full HEVC acceleration, or also partial?

[mindbomb]

Does CUVID only support full HEVC acceleration, or also partial?

it supports hybrid cpu+video decoder for mpeg 2 and vc1 for the 8800gt and other vp2 cards, so I imagine the shader+video decoder methods must work too.

the maxwell cards don't have drivers for windows xp though.

[nevcairiel]

Yes CUVID also supports partial acceleration on Kepler and Maxwell, as well as full acceleration on the GTX 960. 10-bit is not supported on the 960 though through CUVID. Not sure if the API could in theory do it, but it didn't seem to work.

[VictorLS]

CUVID also supports partial acceleration on Kepler and Maxwell, as well as full acceleration on the GTX 960.
Thanks.
10-bit is not supported on the 960 though. It's a pity.
NikosD
can you attach Lentoid 2.0.3.2 here?

[trey]

Hi Everyone,

I'm working on a project using DVBViewer with LAV. I know LAV supports AES3 audio, but not encoding like Dolby E since it is a commercial product. I have an external Dolby E processor and am trying to pass the raw AES3 audio out of the digital port of my sound card. Does anyone know of a way to do this? Or how difficult would it be to develop support for passing AES3?

Thank You in Advance,
Trey

Im planning to get this card next month. Is there any else we should know about this? Does dxva supports 10 & 16 bits? Will I be able to max out complicated pixel shaders found in madvr & mpdn? Up to how much scaling can it take? I presently use gtx 550ti. Will it at least double the performance I'm getting from it?

I'm primary considering this for harware decoding of hevc. Do you happen to know if any gpu supports this anytime soon?

I'll be using gpu for complicated vdeo processing

Thanks

[huhn]

the 960 GTX can do 10 bit HEVC over DXVA right now.
i don't have a general answer to the rest.
the 960 GTX is not that great in term of processing for money.

[meetajhu]

A small tweak to the installer -> Lav filters installer request path to install before asking you to choose what you want to install i.e. x86 or x64 version forcing me to install x64 on Program Files(x86). I suggest using separate installer for x86 and x64. I have no purpose to use x86 anymore because madVR now supports x64.

[nevcairiel]

There are no plans to provide separate installers. You can just disable the x86 versions in the installer if you don't need them, but they don't hurt to have installed either.

[LigH]

Just make sure that the installer doesn't try to install an x64 version to "Program Files (x86)", when the x86 installation is disabled, nev.

[nevcairiel]

The install location is totally irrelevant really. I don't care, and I don't plan to add any complexity with custom magic into the installer script.

[foxyshadis]

Program Files (x86) is only magic to 32-bit apps. It's just another folder for 64-bit apps.

[e-t172]

Program Files (x86) is only magic to 32-bit apps. It's just another folder for 64-bit apps.

It's not magic to anything, and behaves just like any other folder, no matter if you're running a 32-bit or a 64-bit app. It's just a standard folder name.

You might be confused with the SYSWOW64 folder and registry key which are, in fact, magic (32-bit apps are automatically redirected to these instead of the standard ones).

[LigH]

Well, having the system tidy may mean more to some than to others. ;)

[chano22000]

Hello,

I run MPC-HC, LAV filters (external and set as preferred in MPC-HC - all MPC-HC internal LAV filters disabled), madVR x64 on win7 x64. Audio bitstreamed to an AVR.

The following audio track, is not handled by LAV audio (neither external, nor by the MPC-HC embedded one) but is assigned by MPC-HC to MPC-HC AVI <-> AC3/DTS then to Microsoft DTV-DVD Audio Decoder.

Which audio format is this and how to have it handled by LAV audio ?

Thank you very much for your help.

Kind regards.

[nevcairiel]

It probably refuses to use LAV because you have bitstreaming on, but bitstreaming doesnt work in your setup.

[VictorLS]

I can not to regsvr32 ehevcdec.ax under XP, hope yet.
I am Russian from Russia's Crimea and I wrote ticket on Elecard's site. Next day I receive letter with link to download "special for me" version of Elecard HEVC Video Decoder. It registered quite good on clear WinXP without any VCxxx, dotNET and so on (LAV filters too). I like it.
PS. I didn't buy any Elecard's product yet, but support is perfect!!!
One more thing, Elecard HEVC Video Decoder plays all my h265 records (in "decode only I-frames" = "Skip non-key" mode), but when I try to watch 10-bit h265 in three SAT programs I see green color abracadabra. With 8-bit channels all good. I tried all settings in decoder's properties. With LAV Video decoder all channels plays gray with sometimes good frames but very slow and without sound.
nevcairiel, if you don't want to add "decode only I-frames" in LAV filters, may be you can say anything why Elecard work bad with 10-bit? They can not to repeat this problem in tester's department because they can not receive any SAT which I can receive. Russia is the biggest coutry in the world.

[chano22000]

Hi nevcairiel,

Thank you for feedback.

It probably refuses to use LAV because you have bitstreaming on, but bitstreaming doesnt work in your setup.

In any other case, audio is bitstreamed without any issue by LAV audio through MPC-BE wasapi exclusive audio renderer, except the audio track which properties are in my previous message leading to a strange graph.

AFAIK, I have ticked all DTS related audio formats in LAV audio (I do not use mpc-hc internal lav filters) but Graphstudionext does not list LAV audio as a compatible filter.

Could it be that this specific audio format would not be supported by LAV audio ?

Thank you for LAV and your overall work.

Kind regards.

Here is such a sample:

Playback halts for a few seconds using LAV splitter. Seeking and playback is instant using Microsoft splitter or VLC.

Hi nev,

Did you ever manage to reproduce this one? I have been checking the changelogs, but have not seen it addressed anywhere, was wondering if that was because you couldn't reproduce it or had forgotten about it.

[chano22000]

Wrong : libdcadec was disabled.

Problem solved.

[VictorLS]

Did you ever manage to reproduce this one?
For example, I couldn't use LAV Splitter with lav_wmv_slow_seek.wmv in KMP and GraphStudioNext (
But due to lav_wmv_slow_seek.wmv I remembered once more advantage XP compared with Vista-10:
in nVIDIA's Control Panel under XP I can set both 47,952 and 48Hz. nVIDIA's support couldn't to do it in Vista-10 (

[huhn]

windows 7 and newer can do native 23p unlike widnows xp and and custom resolution like 47p or 48p are possible too so not sure what you mean there.

the newer windows version are simply superior in term of video playback.

[VictorLS]

windows7 and newer can do native 23p unlike widnows xp
EDID of my 24" BENQ 241VW contains 60Hz only (for 1920x1200), but
47,952 ... 50 Hz works very well and smooth, despite of "Out of range" 5 seconds window in the center of the screen.
and custom resolution like 47p or 48p are possible too so not sure what you mean there.
in WinXP so, but in Vista-10 (tested by ctrl+j in MadVR and my eyes) I can set either 47,952 or 48Hz - only last created frequency possible to set.

the newer windows version are simply superior in term of video playback.
You mean Enhanced Video Renderer (EVR) and EVR Custom Presenter?
VMR7 under XP never lags, EVR - sometimes lags in Vista-10. I can see that on running string. EVR CP lags more than EVR despite parallel lines in MPC HC. MadVR never lags (as VMR7) but my Athlon 3200+ can 720p only.

[huhn]

because you have problems that doesn't mean the rest of the world has. with string i guess you mean tearing these issue are a problem of the past.

if you use vista you have to make sure the desktop composition is running. vista is a very bad example aynway.

and newer windows version are windows 8. vista is a bit special...

for example the windwos 10 HEVC decoder is one of the fastest software decoder out there if not the fastest software decoder.

I have brought up this issue before... this issue has been around for years. Thank you romulous for reaffirming this issue - both 32 and 64 bit same issue.

No such issue in windows media player, pot, vlc, basically anything that doesn't use lav.

[blaubart]

Hi, I am testing in this 4k setup:
Win7, Intel i7-4790K, Nvidia GTX 960, LG 42UB820V (HDMI 2.0)

Could be an issue of the NV 353.30 Driver or of LAVFilters-0.65.0-20 or both playing 50/60fps 3840x2160 HEVC videos in MPC-HC, or Astra 50fps UHD live-TV in DVBViewer.
I don't know if you can do anything with it but would be interesting to hear if anybody has seen related phenomenons.

Driver indication: the StartSound of 4k 50/60fps Win7 desktop is mostly kind of disrupted or the Sound switching between Windows themes. If I hear that I know - 4k HEVC will run partly disrupted too (picture + sound).
LAV Video Decoder ("dxva2cb direct") MPC-HC [H/W] indication: PDVD generic does it in software ~60% CPU, not totally clean but much better.

For weeks now - if I wanted to have smooth 4k 50/60fps LAV playback or live-TV I had to reboot the PC at least 2 times, sometimes 3, 4 times - until kind of a "golden" reboot, only then after waiting 2-3 minutes LAV -Splitter, -Audio, -Video Decoder, EVR perform totally clean. But just a short standby of Win7 was enough to make an end to these lucky flawless hours, WTF??

Yesterday hard investigation. I let MSConfig do a Diagnostic Startup. Among other nearly all services stopped. While Win7 hardly out of function and a jumping mouse I managed to start my 4k test clip and it played silent but smooth!
Later disabling the services one by one resulted in "Power service" deactivated: mouse jumping, audio disabeled, clip running smoothly.
Power service? Ok, all services back to default changing energy options down just to Power saver (??) did it again, clip running smoothly! To make a long story short the real point was again somewhere else.

It is the Intel TurboBoost!
As long as this is jumping happily up and down 4k 50/60fps HEVC clips (and Win7 system sounds) are also jumping happily. 4k H.264 50/60fps better, all 4k <50fps better, 1080i, 720p, 576i flawlessly.
>Switching energy options to "Power saver" nearly stopps TurboBoost.

Disabling TurboBoost in BIOS - all 4k 50/60fps HEVC playback or liveTV flawlessly anytime at any energy option.
Driver issue? Or could LAV do anything about it? Win8 doing better?

[P.J]

Something is wrong there, Power saver gonna make CPU performance even much worse!

[blaubart]

LAV Video Decoder set to the "new" dxva2 CopyBack on a GTX960 plays 4k video in hardware, GPU 30%, CPU 7%.
So CPU performance is not important.

[VictorLS]

huhn
Vista-10 means from Windows Vista to Windows 10 last Technical Preview.
you mean tearing
yes.
a problem of the past
if I have problem only with tearing which good see on running strings I am saying nothing but many people have such problem.
make sure the desktop composition is running
of course, it running in Vista-7. 8-10 have not Aero. You know this ....
the windwows 10 HEVC decoder is one of the fastest software decoder out there if not the fastest software decoder.
I'll check it when I could.

[huhn]

i don't want to discuss this any longer her in this thread but all newer version of windows have a desktop composition it simply "can't" be disabled anymore if they call it aero or not doesn't matter.
and the desktop composition in vista and 7 is buggy to say it friendly which can easily create tearing with a mismatch.

[nevcairiel]

I agree, if you want to discuss your system-specific problems, open a separate thread. Its entirely unrelated to LAV at this point.

[VictorLS]

I agree with both. Last words: I said Win8 not bad OS, but not so ideal as WinXP - tearing with a mismatch rarely occurs in 8 with EVR (CP).
PS. It's a pity that nevcairiel do not want to add "Skip non-key frames" (as in Elecard HEVC Video Decoder) in LAV Video Decoder to watch smooth slideshow.

[RenderGuy2]

It's probably way too early to consider these things, but I found some HEVC HDR sample videos.

http://demo-uhd3d.com/categorie.php?tag=hdr

When I decode these samples, it seems that the upper 25% or so of the bit-range is empty, even when it appears that there should be highlights. I read that perhaps metadata might be involved in decoding these properly.

I made a 3dlut for MadVR for SMPTE 2084 EOTF sources. Shadows look good so far, they are just lacking highlights.

Perhaps something for the future.

[nevcairiel]

Reduce the number of pre-presented/buffered frames, it'll make the menu react faster. Nothing LAV can influence, the only thing it can do is print the menu onto the frames afterall.
