LAV Filters - DirectShow Media Splitter and Decoders

[nevcairiel]

Forgot to push the ffmpeg repo, apparently. All fixed.

[nevcairiel]

LAV Filters 0.62.0

LAV Splitter
- Fixed: The filtered Forced Subtitles stream did not properly send all related subtitle data in some cases

LAV Video
- NEW: Implemented a WMV9 MFT decoder to replace the old DMO decoder for VC-1/WMV3 on Windows 7 and above
- NEW: Support for VP7 video
- Fixed: Multi-threaded video decoding could result in a handle leak on some systems
- Fixed: Video processing was slow on Windows XP due to inefficient memcpy use
- Fixed: DVD subtitles could overlap on some discs

LAV Audio
- Fixed: Dynamic format switching to an audio stream with a different sample rate did not work in some cases

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

Mostly pushing this release to get updated ffmpeg libraries out, as well as not cause the new things to rot too long.

WMV9 MFT

As it appears, the WMV9 DMO decoder is kinda broken on Windows 8.1, it doesn't properly identify interlaced videos anymore, which causes them to never engage deinterlacing.
To solve this problem, I've implement a new wrapper around Microsofts decoder, using the MFT (Media Foundation Transform), instead of the DMO. DMOs are a tech from Windows XP and before, and are really old and deprecated, while MFTs are new and clearly better supported - plus getting the information I need out of it was actually quite a bit easier than with the DMO before.

Note that this has no influence on anything DirectShow, LAV is not a Media Foundation filter all of the sudden, it just happens to use the WMV9 MFT, nothing else changes.

Anyway, have fun, and as always report any regressions you find.

These are just concept images the final images will be properly scaled and i'll create a system tray icon for each of them.

Thanks for the new version!

LAV Video decoder Properties -> Formats , still say "Use Microsoft WMV9 DMO decoder ....".

Also, having installed both versions (x86 & x64), I realized that whatever change I do to one version properties (for example x86 from DXVA native to DXVA copy-back), it happens also to the other version (x64) and the opposite.

Is it normal ?

I've been using LAV + MPC-HC for streaming MPEG-TS from my ISP's recording service. Aside from the playback taking some extra seconds to start comparing to VLC, it's working very well.

In order to be able to rewind and fast-forward and get the full duration of a file instead of just a couple of seconds from the beginning, I have to insert the following to registry:

[Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\http]
"Source Filter"="{B98D13E7-55DB-4385-A33D-09FD1BA26338}"

This enables splitting video and audio from HTTP protocol with LAV Splitter, right?

Could you make this a default setting, or is there some downside to this? I mean, this could help someone else, too.

I'd like to point out that the latest version, spesifically the latest FFMPEG update, significantly shortened the loading times (I'd say about 5 to 10 times), so absolutely great!

Nev, it seems I have some MPEG-1 videos that LAV Video doesn't decode. Windows MPEG's decoder is used instead.

Here's one that does decode with LAV Video: http://www.mediafire.com/watch/ajj0mc8z4874kf4

And here one that doesn't: http://www.mediafire.com/watch/s867ud5hbond1a8

On my computer, the second sample plays fine with the latest LAV Video & Splitter in Graphstudio.

BTW, you should already have learned how to use MediaFire in the RIGHT way

Funny, only happens when playing in MPC-HC, LAV Video is used for both in GraphStudioNext. No idea what could be causing it, settings are the same of course.

I know how to use MediaFire, it's just that I consider the people on this forum smart enough to press the "Download" button right by the video preview I purposedly used. Guess I'll have to make an exception with you from now on

I took the time to confirm it, if the problem is not on your machine, then
it is in the most recent builds of MPC-HC (which I don't use BTW ~~
I tested the sample with MPC-HC Lite 1.6.8.7391 and MPC-BE 1.4.3.4793).

in what program do you see that? have you tried to use other player?
On the screenshot i just see that one piece of software cannot display chapter names in UTF-8, not more.

I'm quite sure that proper UTF-8 chapter names are being processed correctly, so you should ideally check if they are correctly encoded in the file.

In any case, a file showing the problem would be good.

Hello, I am trying to do some complex stream selection rules in the advanced section but its not working. Here is what I got going:

jpn|d:eng|d;jpn|!d:eng|!d

so if jpn audio is default then load english subtitle that is default and if jpn audio is not default then load english subtitle that is not default. However what ends up happening is that it loads the jpn audio but it doesn't load any subtitles at all. I guess its only looking at that I set preferred audio in the dialog above to jpn,eng.

I am doing this because some anime I have are english audio default and the default subtitle track is for signs/songs. However everything else I have is japanese audio default with default full english subs. If there is an easier way to do this that I am overlooking let me know. The main problem I am having is the usual jpn:eng chooses the first track which on this particular anime is the english signs rather than full subs.

My guess is that the code doesn't look at whether the audio track has been flagged default or not so its simply not working there because it is expecting a three letter value and doesn't know what jpn|d means.

Having this approved would help with that.
Nev can we get this requested feature of selecting subtitles by substring match added in LAV?
