LAV Filters - DirectShow Media Splitter and Decoders

[PPPPark]

No problem with LAV-0.49-b46fb1c(sw/cuvid/native/cb) on my new GT520(296.10whql).

PS: MPC-HC DXVA and ffdshow DXVA failed on deinterlacing.



only cyberlink CLCvd.ax can 30FPS-60FPS~

[LordX2]

I have two questions about LAV - easy one first:

I have a MKV that ONLY has a Dolby Digital TRUE-HD audio stream.

My receiver is a little older and only takes optical input - which is how I have it setup right now.

LAV Audio bitstreams Dolby Digital and DTS just fine to the amp.

However, when I play the MKV with Tru-HD - it outputs only 'normal' audio to the amp.

With FFD Audio - I was able to re-encode the stream to regular DD at 640k.

Can LAV Audio re-encode to AC3 output so I can at least have real surround sound watching this video?

[Anima123]

I also reported a blue screen problem with DXVA2(copy-back) mode. It seems the problem only exist with certain GPUs.

No problem with LAV-0.49-b46fb1c(sw/cuvid/native/cb) on my new GT520(296.10whql).
On my GTX-570 with LAV, the field order was wrong for DXVA-CB and pure software decoding.
After pressing <ctrl>+<alt>+<shift> + F twice to set the field order from "auto" to "top first" in Madvr was much better.

Only LAV-CUVID gave the correct field order.
Maybe the file was wrong encoded ?
Wat is in fact the correct field order setting for MBAFF ?

CoreAVC with "deinterlace by hardware" didn't trigger the Madvr deinterlacer at all : I got an ugly interlaced image.
However, after enabling the "agressive" setting on CoreAVC, Madvr started to deinterlace and fieldorder was OK .

Also the internal FFmpeg based decoder from MPC-HC gave the wrong field order.

It could be that all decoders are right about the field order, but Madvr either can't read the info or reads it in a wrong way.
But I doubt this is the case, because I got similar things with EVR-CP.

to sum up :
LAV-splitter always as splitter used

LAV-vid (softw. decoding) -> Madvr = wrong field order
LAV-vid (softw. decoding) -> EVR-CP = wrong field order
LAV-vid (DVXA-CB mode) -> Madvr = wrong field order
LAV-vid (CUVID mode) -> Madvr = field order OK
LAV-vid (DVXA-Native) -> EVR-CP = wrong field order

MPC-HC (internal FFmpeg) -> Madvr = wrong field order
FFDshow (softw, NV12 out) -> EVR-CP = wrong field order
FFDshow (softw, NV12 out) -> Madvr = wrong field order
CoreAVC (software dec) -> MadVR = no de-interlacing
CoreAVC (software dec) -> EVR-CP = no de-interlacing
CoreAVC (CUVID) -> Madvr = no de-interlacing
CoreAVC (CUVID) -> EVR-CP = no de-interlacing
CoreAVC (software, aggressive on) -> MadVR = field order OK
CoreAVC (software, aggressive on) -> EVR-CP = field order OK
CoreAVC (CUDA, aggressive on) -> MadVR = field order OK
ArcSoft (Software) + MadVR -> = field order OK

Where there was a "wrong field order", it could be corrected by setting Madvr in "top field first" mode, or set "top field first" in the decoder where applicable.
This gave the "perfect image" for this clip.


PS: MPC-HC DXVA and ffdshow DXVA failed on deinterlacing.
Failed, you mean field order wrong or no deinterlacing at all ?

no deinterlacing

[Pat357]

Every decoder can make that the output in the renderer is 60fps for a 30fps interlaced movie, because it's not the decoder that has to work harder for this, it's the renderer !

The decoder set's a flag for every frame (indicating it's interlaced) and it's the renderer that will mostly double the framerate.
This is how EVR's hardware de-interlacing and Madvr DXVA interlacing work.

There are a few exceptions where the decoder does produce the 60fps : Lav cuvid, lav with Yadif, CoreAVC Cuda,... some MPEG-decoders with own deinterlacing (which quality is often worse than real HW deinterlacing).

[Pat357]

I found one: Playback is not smooth with Pot DXVA, LAV CB, LAV native although they double fps already.
What you see is probably caused by the wrong "field order".
Set in LAV the field order from "auto" to "Top-Field-First" and it should look much better.

[egur]

Egur,
do you have plans to add this to your QuickSync decoder soon?
Last week I bought a 3D projector and I have to say that the commercial players are veeeeery inconvenient and I'm craving for the simplicity/automation of Zoom Player / MPC-HC

i didn't plan this yet.
Splitter support is a must before even trying to do any work.

Nev, Madshi:
The media SDK MVC decode sample behaves the following way:
1 output pin.
View frames/buffers are sent sequentially (separately) to the renderer.
View 0 (base) has proper time stamp. View 1 has rtStart == rtEnd. Not sure which view is left side.

Other than the time stamp manipulation I didn't see any special handling on the decoder side (interface or protocol changes).

SandyBridge supports DXVA2 decoding of MVC. This (http://www.microsoft.com/download/en/details.aspx?id=25200)document explains how this done.

In order to push open source 3D playback, we need:
* Samples.
* Splitter support. Haali already works?
* Renderer support. Media SDK's custom EVR supports 3D. Not sure how it behaves on standard monitors. May need a debug feature - show stereo frames side by side (or one on top of the other).

[madshi]

Media SDK's custom EVR supports 3D.
It does? For which GPUs? The problem is that every GPU manufacturer has totally private ways to do frame packed HDMI 1.4 3D output. There's no MS API available for that, so if you want to do it, you have to write custom code for every GPU manufacturer.

I found strange issue when using Microsoft DTV-DVD Audio Decoder instead of LAV Audio Decoder. At first it is good, but after seek, pause, stop/play video starts to play as fast as my hardware can decode it :) If it is bug in Microsoft decoder then block it to prevent using it with LAV, it's not working anyway.

EVOs use soft-telecine, 24p is correct.

[PPPPark]

evos use soft-telecine, 24p is correct.

ok~~~~~:d

[dansrfe]

Just curious, are there any future plans for LAV and madVR to support 3D decoding of blurays and mkvs?

[Pat357]

EVOs use soft-telecine, 24p is correct.
Can't download the file, so I will just ask :
Does Lav-video output 24 fps or 29.97 ?
Is Lav doing the IVTC from this file ?

Does LAV still set the IVTC flags for the renderer (repeat flags) ?
When using Madvr, does LAV do the IVTC (no repeat flags for renderer) or does Madvr do the IVTC ?

A lot of questions, but a one line answer should be enough to make me understand how IVTC works for EVO with LAV.

Have you thought about mixing EVO and "interlaced" or "hard telecined" content ?

There is no IVTC to be done, the file contains 24 frames per second.
Soft-Telecine just adds some flags that would tell the renderer which fields to show twice to reach 30p, if you just ignore those flags, you get nice and fluid 24p.

LAV Video does output those flags, and madVR might take them into account to ensure mixed soft-telecine/hard-telecine is properly processed, but other then that, LAV just outputs the decoded frames and does not change them in any way.

[rurimoon]

Interlaced clip (http://www.wupload.com/file/2651705787)

MediaInfo show 25fps, LAV show 50fps. No deinterlace is performed on madVR because of this.

Hi Nev,
I've release a new version that fixes playback under WMC FSE.
Because I didn't want to break ffdshow's design there's one limitation - under WMC only, I will enable SW emulation to pass media type checks and also play in SW codec profiles unsupported by HW (but supported in SW).

Basically the same D3D9 limitations as your DXVA implementations under FSE.

If you want to make LAV perfect with respect to FSE (e.g. fix your DXVA under FSE at the same time) you should:
* Perform decoder media type checks after the renderer is connected and a D3D9 device manager is retrieved.
* Fallback to SW if the checks fail.

[DragonQ]

Off-topic but I figured you guys would know:

What's the best program to use for sorting out installed codecs and their merits? It can kind of be done within MPC-HC but it's fiddly and I'm sure there's an easier way.

Hi guys,
Is there a way to change the default subtitle if there are multiple subs with the same language?

I think that default is set in the MKV file, so you would have to remux the MKV file with a different subtitle set as default, and probably a different audio stream set as default while you are at it. Since the language are identical I don't think the splitter could pick up styled against signs, since that field does not follow any standard labelling.

[e1iminator]

great job lavcuvid!!!

i have some issues with dvb applicaions (smartdvb and progdvb)

thanks

[sidi0us]

Since the language are identical I don't think the splitter could pick up styled against signs, since that field does not follow any standard labelling.

I thought that if we can specify a sub by language and it didn't mattered if it was forced or default, we can do it by "id/number" or "track name".
For example If I have an entire TV series where the sub id and track name is identical in each episode, I can go to splitter settings and enter the track id or number.
This will basically eliminate the time I need to manually change the default subs with the header editor for each episode.
Anyway this problem only occurs when you have multiple subs with the same language, otherwise you just go in LAV Splitter settings and change the default lang.

LAV Filters 0.50

LAV Splitter
- Improved support for H264 Elementary Streams
- Fixed a regression with seeking in MPEG-TS files recorded by some HD-PVR devices

LAV Video
- New Worker Thread design for Decoding/Deinterlacing
- WMV9+YADIF is up to 40% faster
- Improved DXVA2 for MPEG-2 interlaced
- Improved H264 DXVA2 on AMD with certain streams
- Improved CUVID support for 4K streams on supported hardware (GT520, GTX680, other VP5 hardware)

LAV Audio
- Added support for RealAudio Lossless (RALF)


Download: Installer (both x86/x64) (http://files.1f0.de/lavf/LAVFilters-0.50.exe) -- Zips: 32-bit (http://files.1f0.de/lavf/LAVFilters-0.50.zip) & 64-bit (http://files.1f0.de/lavf/LAVFilters-0.50-x64.zip)

This has been cooking for a while, and i think its ready now.

Mostly small bugfixes, and of course the new worker thread in LAV Video. Right now, only the WMV9 decoder really benefits from it, but it was the slowest decoder too.
I hope no problems with the worker thread remain, it should've been thoroughly tested by now.

As a side note, the 301.10 NVIDIA driver seems to have fixed the MPEG4-ASP problems, at least it works on my new GTX680.
Additionally, CUVID should now work with 4K streams on VP5 cards, although its not extremely fast (37-40 fps in my short tests), however DXVA2 seems to still have issues (crashes). I think its driver related.

Just a quick FYI, development might be a bit slower for the next few month, i have another project that needs more attention (completely unrelated to Video things).

If you want to set the merits systemwide (of course, that'll depend on the player's preference as well), there's Win7DSFilterTweaker (http://www.codecguide.com/windows7_preferred_filter_tweaker.htm).

mkvmerge gui also has a header editor which allows you to change these settings without a full remux.

- and the Tray-Icon to manage the Editions and other things.

Is LAV splitter able to handle the MKV-Menu (http://matroska.org/technical/specs/chapters/index.html#dvd) features (ChapterProcess; ChapterProcessCodecID...)?

Get the DSF/MFT Viewer from :
http://bluesky23.yu-nagi.com/en/index.html (supports 32 & 64 bit)

An other very handy one is DSFM
http://www.softella.com/dsfm/index.en.htm (only 32 bit, but runs fine on Win7 x64)

I use mainly these 2.

[Budtz]

Thx for the new version!

Is it possible to set up the splitter so that it prefers Danish subtitles - and English when no Danish are available? This has to be regardless of whether they are embedded or external.

Right now I have a file that has Danish external subtitles but I have to select them manually once playback starts. If I set mpc-hc to prefer external it chooses the external ones regardless of language it seems.

[nevcairiel]

The splitter cannot control external subtitles. In fact, it doesn't know about them at all.

Thanks! Unfortunately this tool doesn't seem to list LAV Audio as an option under LATM AAC, even though LAV supports it. In fact, I can't see LAV Audio anywhere. :(

- Improved DXVA2 for MPEG-2 interlaced
Is this "improved" as in performance, power usage, stream compatibility, or...?

[LordX2]

Does the new version allow for encoding of DD True-Hd or DTS-MA to AC3? For those of us who do not have an up to date receiver?

[cengizhan]

nevcairiel,

Thanks for all your efforts. I really appreciate it.

[mindbomb]

Does the new version allow for encoding of DD True-Hd or DTS-MA to AC3? For those of us who do not have an up to date receiver?

i'm gonna guess no.

I don't really have much faith in free encoders for ac3 or dts tbh.

You can use reclock if you absolutely need a software encoder.

There are sound cards with dolby digital live and dts connect also.
I'm not clear on how smart they are in determining when to encode (ie, do they only encode multichannel?)
Also, not clear on if they properly downmix 7.1 to 5.1 before encoding.

Or you can start using analog.

If you have a DGDecNV licence, could you do this benchmark (http://forum.doom9.org/showthread.php?t=161948) with your new GTX680 and post the results there please? I'm really interested how the card performs for decoding.

[LordX2]

Thanks for the quick reply Mindbomb.

FFDshow audio encodes true-hd to regular AC3. And you can set it to only encode 5.1 streams (so it doesn't hit every 2 channel file).

I have it installed as well, and can switch back to it if I need it for a file.

Was just wondering.

Thanks again!

Hi guys,
Is there a way to change the default subtitle if there are multiple subs with the same language?

http://i371.photobucket.com/albums/oo154/sidi0us/sub.jpg

I'm using PotPlayer 1.5.32772 with LAV Filters 0.49.

One workaround for this is for the encoder to label the subs to specify what audio track it's meant to be used with.

So the subtitle track that includes dialog and signs would be marked as a "Japanese" subtitle track (or whatever the original audio language is), even though the subs themselves are English. And the other sub track would be labeled "English" because it's meant to be utilized with the English audio dub.

But then this causes problems if your preferred subtitle settings specify English over Japanese. :rolleyes:

[mindbomb]

FFDshow audio encodes true-hd to regular AC3. And you can set it to only encode 5.1 streams (so it doesn't hit every 2 channel file).

yea, reclock allows you to do this also. you should play around with it.

I know that ffdshow and reclock can be configured to only encode multichannel, I'm wondering if the same can be done with realtek, creative, or asus drivers.

It could prove useful, especially with something like the asus xonar ds, which can encode to 1.5 megabit dts with dts connect.

[nevcairiel]

I don't really have much faith in free encoders for ac3 or dts tbh.

ffmpegs AC3 encoder is doing a pretty good job, however i have no plans to offer such an option

I don't have a license, but i can tell you that the performance is about twice that of a VP4 decoder.

[sidi0us]

But then this causes problems if your preferred subtitle settings specify English over Japanese. :rolleyes:

That will do, as long as they mark subs with different languages there will be no problem, you can set the default one in splitter settings. I guess I'll have to change them manualy :(.

[sneaker_ger]

Or instead of flagging the tracks with the wrong language, you could flag the second subtitle track as default instead of the first one. You can easily batch the process with mkvtoolnix (there's even a GUI for that: http://forum.doom9.org/showthread.php?t=163753). Then set LAV Splitter to prefer the default track, if you haven't done that already.

[Village Guy]

Along with other JRiver MC users we have been trying to understand why JMC crashes when playing Neverland and yet it plays fine on MPC-HC and WMC. It would appear to be the LAV splitter because if I replace the default MPC splitter with LAV V5.0 MPC-HC also crashes.

Here is the thread (http://yabb.jriver.com/interact/index.php?topic=71070.0)

Is there any way I can debug or log information to help resolve the anomaly?

[XadoX]

Since this thread is growing so fast I am not realy up to date with the current LAV progress.

I am already using LAV-Splitter and LAV-Audio, but I am still using Microsofts DXVA decoder for decoding h264 files with media portal on my AMD E-350.

If I also switch to LAV-Video, will there be any benefits instead of using Microsofts DXVA?

[pankov]

i didn't plan this yet.
Splitter support is a must before even trying to do any work.
...
In order to push open source 3D playback, we need:
* Samples.
* Splitter support. Haali already works?
* Renderer support. Media SDK's custom EVR supports 3D. Not sure how it behaves on standard monitors. May need a debug feature - show stereo frames side by side (or one on top of the other).
Eric,
I think/hope that the first two steps are very easy to accomplish
1. Each 3D bluray's siff files can be used as a sample
2. As I mentioned before the Haali Media Spliter does have a "stereo" pin so I think it does support it. Also the patched MPC MPEG Splitter does too. (thanks to mathh40 who provided the link to the patches http://www.3dtv.at/OpenSource/Index_de.aspx ... if they are not yet included in the main trunk). And finally I think/hope Nev will be able to add support to LAV Splitter pretty soon.

Now, when it comes to the third point (the renderer) we have a bigger problem. With all the unknowns how to switch to frame packing mode it will be difficult but if there is a sample for Intel ... and your connections inside the company ... I think this shouldn't be so hard and should be the first step ... we only need madshi to dedicate more time on it. (madshi, I'm just hoping you will do it - I'm not at all trying to dictate how you work on your renderer)

btw, Eric,
do you have a working application based on this custom EVR? Can you check if there is a limitation to be used only on the primary monitor as it is with Arcsoft's TMT. Does anybody know if this is a general limitation or simply how the guys at Arcsoft did it?

Eric, Nev, madshi,
does anyone of you own/use a 3D TV/projector? Do you like 3D at all?

P.S.
Nev,
if you don't like this talk to happen in LAV Filters thread I can start a new one and hopefully you all can join.
