LAV Filters - DirectShow Media Splitter and Decoders

[cyberbeing]

There is a seeking bug with subtitles. Sometimes the old line(s) being displayed before a seek, will still be displayed until the end of their duration after a seek, overlapping any new lines from after the seek. Somewhat hard to reproduce, yet it occurs more often when using the madVR FSE mode seekbar for some reason.

Misaligned chroma on uneven subtitles lines seems to be resolved now:

In FSE mode its easy to reproduce. madVR must be doing something odd when seeking.
When i seek using MPC-HCs seek bar, the DVD Navigator sends a proper BeginFlush/EndFlush sequence to the decoder. When i seek with madVRs FSE bar, it just starts sending frames from another point in time, it doesnt flush the decoder. This also causes image corruption for a few frames.

I can probably make the old lines disappear if a new one comes up, but it doesn't look like i can make them disappear instantly. This is rather odd behaviour, i'm inclined to blame madVR for weird seeking. :p

Glad my trickery with positioning the subtitles better worked. :)

Here is a new test build, with all recent improvements to DVD menu rendering.

x86: http://files.1f0.de/lavf/LAVFilters-0.52-39-gf0b33ee.zip
x64: http://files.1f0.de/lavf/LAVFilters-0.52-39-gf0b33ee-x64.zip

just to inform,
the 2 files within are still using the old naming convention of ffmpeg
avutil-lav-51.dll ---> should be avutil-lav-52.dll?
avresample-lav-0.dll ---> should be avresample-lav-1.dll?

[nevcairiel]

You must be seeing things, those zips contain the correct files. Both avutil-lav-52.dll and avresample-lav-1.dll.

arghh - you are correct - I was looking in an older testfile by mistake
sorry about the incorrect post

LAV cant decode the TAK file.The correct expression is "ffmpeg can't decode the TAK file." :PActually it can (implemented through reverse-engineering):

Actually it can (implemented through reverse-engineering):



Yes and i have recently added support in LAV however the point was that it cannot play that particular file. It uses a type of encoding not implemented in the FFmpeg (yet)

[06_taro]

Just because FFmpeg is still not backward compatible with some old tak format, and that particular file was compressed by tak 1.0.0:

FWIW, I'm using the official IMediaSeeking interface (and no, I'm *not* using the "AM_SEEKING_NoFlush" flag). Not sure what I could do differently there?

[nevcairiel]

Thats explains a lot, it uses a special seeking interface on the DVD Navigator. Like, WTF Microsoft, why re-implement the wheel.
Can't really blame madVR for doing something wrong, but i'm sure madshi can fix this anyway? :)

[petran79]

it has been mentioned before probably but there is one issue.
it is corrected now for the most part but there are some problems
LAV Video decoder together with MadVR detects P010 encoded videos and displays them correctly.

Before that I had to disable most decoders in the LAV Video decoder, except NV12, YUY and P010. Or else P010 videos would appear as 8-bit or would not show at all

Now I have a video encoded in Y410 4:4:4 format. If I have all decoders enabled, it appears as YUY 8-bit 4:2:0

in order to appear correctly I have to disable all decoder formats except the 4:4:4 ones.

or else it appears even as P010 16-bit.

[madshi]

Thanks Cyberlink, that should be quite possible for madVR to do, too.

Works just fine for me. :P

[starkline]

nevcairiel-- I believe that 0.52 introduced a slight regression in the stream aspect ratio detection for asf containers. The X and Y coordinates are reversed for the source aspect ratio. Reverting lav to 51.3 fixes the issue.

I do not notice any problems with mp4 containers.

I posted before my brain engaged. This error was the result of an upstream regression in ffmpeg, which I reported on ffmpeg's bug tracker. It should be fixed in future builds.

I saw the changes from today, and they also added support for aspect ratio which was previously not detected at all, its all good now.

Is the "Availability of custom high-quality converters" chart from LAVPixFmtConverter.cpp up-to-date?

Latest GIT build (11165fd2c17c) is causing a crash in avcodec-lav-54.dll with VC-1 DXVA Copy Back mode. Seems any progressive VC-1 source using WMV9-DMO in LAV. I tried it with MPC-BE and MC18 b68.

Should be fixed, was a rather silly mistake trying to fix something else.

[Reino]

Yes and i have recently added support in LAV.When was that? Not in 0.52.0 at least.

[ryrynz]

@Corone TAK support was added 2 days ago, you'll find it included in the test build Nev uploaded (http://forum.doom9.org/showthread.php?p=1598822#post1598822) , it'll be included in the next release sometime in the next few days.

[Pomegranate]

Hi, I'm new here and I had to wait 5 days, but your audio decoder saved me a quite a bit of money (I was going to buy a brand new receiver). So I want to say thanks to you.

One thing I'm not so clear on is what decoder is being used for the lossy DTS formats?

[VipZ]

Thanks for the WMV and Metadata updates and hope you will find a solution one day to get Metadata on streaming.

With the latest build it seems EVO's no longer work and just crash MPC.

Here's a sample if you need, http://www.mediafire.com/download.php?y14tvaw38t8d18p

In MPC it works indeed!

that happens in Potplayer only for some strange reason!

also another weird issue, small details really but since I had the chance to spot it why not mention it.

somehow this Xvid video seems to be broken when played with LAV and CUDA on. When I turned it off or use DVXA, it appears normal

This happens on the desktop in both XP and 7. I had a GTS450 and upgraded it to a GTX660 but still the same issue.

On the laptop though with Nvidia GT555M the video displays correctly with CUDA on.

Currently I have only the desktop for screen shots.

on CoreAVC and Madvr there arent any issues.


with CUDA

http://www.abload.de/image.php?img=testebebe.jpg

without CUDA

http://www.abload.de/image.php?img=test297cfu.jpg

[nevcairiel]

If a video decodes wrong with CUDA, all i can recommend is to try a different driver. If all else fails, you can turn off MPEG-4 CUDA decoding, there is a checkbox for that format ("MPEG-4" checkbox below the hw decoder dropdown). There have been issues in older drivers before with MPEG-4/Xvid.

PS:
CoreAVC does not support Xvid/MPEG-4 ASP decoding, so there wouldn't be any issues. :p

[Superb]

Or maybe he should try and send the sample to Nvidia, so they'll fix their own crap. :)

Fixed, thanks for the sample.
Best answer I could have hoped for... Thank you!

Download: Installer (both x86/x64) (http://files.1f0.de/lavf/LAVFilters-0.53.exe) -- Zips: 32-bit (http://files.1f0.de/lavf/LAVFilters-0.53.zip) & 64-bit (http://files.1f0.de/lavf/LAVFilters-0.53-x64.zip)

A quick FYI at the start, as of this version all my official binaries (both installer and all dll/ax files) will be digitally signed, so the validity and integrity of the binaries can be ensured.
Of course everyone can still build their own, or use nightly builds from someone else, but only the official builds will have my signature, and thus can be easily identified as such.

Ok, back to business.

DVD improvements

After a lot of testing, and quite a few samples i got from you guys, DVD support seems to be working much better now.
If you still have a problematic menu, you can extract only the menu from a DVD by simply zip'ing up all the IFO/BUP files, the VIDEO_TS.VOB, and all VTS_xx_0.VOBs (VTS files ending with 0 are for menus, 1 and above are content).

Additionally, QuickSync can now be used for DVD playback.

Speaking of QuickSync, i also worked on making it usable in FSE players, like WMC.
Of course the usual restrictions apply, which means you cannot use any post-processor between LAV Video and EVR, otherwise QuickSync will not be able to get access to the D3D interfaces it needs.
To improve the behaviour overall, QuickSync now also has a much more graceful fallback to software decoding if it cannot obtain the required D3D resources.

I also tested this version on Windows 8, and beside the WMV9 DMO crash i fixed, everything seems to be in perfect working order.

Oh and a quick note about image files. LAV Splitter can now read some image formats (as outlined in the changelog above), and LAV Video can also decode all these formats, including 16-bit PNGs/TIFFs, however LAV Video does not yet have the ability to output untouched 16-bit RGB, so it'll be converted to 8-bit RGB for the time being. I'll add native RGB48/RGB64 support in a future version.

So with all that said, have fun!

[SamuriHL]

Nice. That should pretty well wrap things up for MC, as well. Awesome.

[mark0077]

Hi nev, thanks for the new version. I have packaged up the menu files for Star Wars Episode III, its ~700MB though :O They still seem to have the issues moving between the big menus, ie player seeming to freeze up, but it eventually gets out of it and moves on. Let me know and I can try to find somewhere that'll let me upload the menus, might take a month on my broadband connection though :D

[Sebastiii]

Nice Nev :)
Thanks a lot :)

[mindbomb]

i have question about dxva native and dvd subtitles:
do the commercial players like arcsoft tmt5 have a way to do it?

[nevcairiel]

There is plenty ways to do it, the usual way that MS and commercial players use is to use EVR and send the subtitles on a secondary output pin, and EVR paints it on top of the frame. This is not supported by LAV and will not be.
There are other plans to make it work in the future. We'll see.

If people prefer, i can turn native dxva off for DVD decoding, so that it automatically falls back to software, and you don't happen to suffer from missing subtitles.
The menu is otherwise still usable, you just dont see which buttons you highlight, but you can still click them. :)

[hoborg]

nevcairiel:
Thanks for new release!

Regarding "Added support for reading image files (tiff, png, jpeg, tga, bmp)"
I just tryed *.PNG files and all i can see is black - tested in Graphstudio, Win7 x64, EVR as a renderer and LAVF x86. Trying to open it in MPC-HC will result in Crash in "KERNELBASE.dll" (not every times).
If i try to open *.JPG, it will open and i have a picture, but it will use "Generate Still Video" + "Color Space Converter" + EVR.
Trying to open BMP will result in Graphstudio crash, but MPC-HC is working LAVF splitter+Video decoder + EVR

Did i missing something?

Blu-ray discs often have multiple streams at different resolutions. You've had to write your own resizer to make them fit properly. Giving this to the renderer on a 2nd pin makes a lot more sense. For DVD no one cares since its so easily decoded anyway. I bet if madvr supported more than 1 pin you would rethink this.

Thanks for answering my question. I don't think it is a big deal feature to have, since lav video has plenty of alternatives to dxva native, I was just wondering how/if it was possible.

And yea, I think it would be good if dxva could be off for dvd decoding. I can't imagine anyone minding the extra cpu usage that comes with decoding sd mpeg2.

[rack04]

I just noticed that when I play my retail Blu-ray version of Cars 2 that spanish is loaded at the audio and english subtitles are shown using the following subtitle configuration:

"eng:eng|f;eng:off;*:eng"

I would not.

The fact that EVR needs a special custom mixer to actually be usable for anything but DVD subtitles is a clear sign that the solution isn't as perfect as you make it out to be.
Maybe if EVR would support this behaviour properly out of the box, maybe then.

Anyhow, this is a special situation for DVD menus/subtitles, because the DVD navigator strictly requires those to be handled by the decoder, can't really avoid that. Has nothing to do with Blu-rays.

PS:
I already have a resizer.


Any idea why this is happening?

Like sneaker_ger hinted, you have not configured the audio language, and spanish is 7.1 while english is only 5.1, so it prefers that.

This BD doesn't work with LAV filters. It plays fine with LAV on MPC-HC but fails to play on WMP or WMC, it also reports playtime as 1200 minutes or so. It works fine with ffdshow and WMP/WMC. Dunno if it's a LAV problem or LAV+VSfilter, it has PGS subtitles. Out of my 100+ remuxes i've ripped to my HTPC, this is the only one that doesn't work on LAV.

Dark Shadows sample (50Mb) (http://sdrv.ms/Q61lmZ)

I gave up on this but encountered another remux with the same problem. I checked all my remuxes and 3 out of 100+ had this problem. I checked those remuxes on eac3to and what's common in those is 16 bits DTS Master Audio. All other remuxes have 24 bits DTS Master Audio and those work fine.

Anyone have any ideas what might cause this?

Hi nevcairiel! Thank you for new new build, works fine here (tested yesterday evening).

One question to the COM interface: how can i obtain the instance of (e.g.) LAVAudioSettings? When i call

AudioFilter.QueryInterface(IID_ILAVFSettings,LAVAudioSettings);

it returns nothing. The filter graph is just built but not running when i call this.

Edit: sorry, forget it, it works, had a simple typo: Should use IID_ILAVAudioSettings for that :rolleyes:

[mindbomb]

I'm experiencing a bit of lag interacting with dvd menus when playing a dvd over the network.
Local playback is fine.

anyone else have this problem?

How are you signing the installer? Did you buy a certificate or generate one yourself?
I'm interested in the procedure, I want to sign ZP's EXEs as well and would like to understand the options.

I bought a certificate. You could of course use a self-signed certificate, but that doesn't get windows to trust your executable anymore then without one.
