The latest nightly should give those checkboxes a bit more room, hopefully it looks better now. On my system I can fit another full character in there now without clipping, but oh well.

I checked the latest nightly build 0.67.146-git - now everything appears normal and looks neat.

Many thanks!

And yet, nevcairiel, I discovered that Windows XP, using "NVIDIA CUVID"-Decoder, incorrectly playback video files at a frame rate = 60 FPS.
Jerks observed deviations and missing frames. Perhaps the case in timestamps. Do you have the ability to fix this?
Just because of this bug is inconvenient to use "CUVID-Decoder".
P.S. Link to sample: https://dropmefiles.com/c9WKm

Looks fine here, and I'm not supporting XP anymore, especially when it comes to HWAccel, sorry.

Hello,

Sorry for my english but i have a big problem with the latest lavfilters:
I can't bitstream Dolby Digital + (eac3) and DTS-HD HRA.

With Dolby Digital +, DD logo appear on the Onkyo but no sound.
With DTS-HD HRA, i have only the DTS Core.

No problem with Dolby Digital, TrueHD, DTS or DTS-HD MA.

Windows 10
NVIDIA GTX 960
Onkyo TX-RZ900
Latest MPC HC nightly build

Can you help me ?
I have tested many things, change all options in Lav Filters, but no luck

Thanks

Can you supply a portable version of nightly lav? In most cases, we use lav with mpc-hc. And if you directly pack the files, I think it's better and more convenient than to compile to a installer.

There are no plans to offer LAV nightlies in any other form, sorry.

@nijiko: you can use the Inno Setup Unpacker for extracting the contents from the installer.
If you prefer a GUI, download the Universal Extractor package, and then update its innounp.exe to the newest version.

Is there a possibility of Atmos decoding with LAV in the near future?
I imagine it as DTS-HD MA used to be for a long time, with an external dll loaded by LAV.
(Somehow I don't think that we'll see Atmos decoding in ffmpeg anytime soon.)

I'm sure it's planned, but just like with DTS:X, we don't know when it will be possible. It's basically nothing more than metadata on top of the TrueHD stream and DTS-HD Ma stream (for DTS:X).

The stream might be. But I'm sure decoding is not as easy. It needs HTRF and who knows what sort of other processing to sound right.

LAV Filters 0.68
Code:
LAV Splitter
- NEW: H.264 MVC 3D demuxing from MKV 3D, Blu-ray discs and Blu-ray SSIF files
- Fixed: The bitdepth of DTS-HD MA streams is reported properly in the stream information

LAV Video
- NEW: H.264 MVC 3D decoding (requires madVR 0.90 or newer)
- NEW: HEVC HDR streams export the HDR metadata to the video renderer (requires madVR 0.89.18 or newer)
- NEW: VP9 DXVA2 Hardware Acceleration
- NEW: Weston Three Field Deinterlacing filter (w3fdif)
- NEW: Ability to choose which GPU is used for DXVA2-CopyBack decoding
- Changed: Removed the CUVID HQ processing option, it is now automatically used when appropriate
- Fixed: CUVID would crash when playing certain HEVC files
- Fixed: Some pixel format conversions were much slower than expected
- Fixed: Pixel Format changes mid-stream were not re-negotiated with the renderer in all cases
- Fixed: Changes in the framerate due to software deinterlacing are properly reflected in the media type

LAV Audio
- Fixed: Increased PCM buffering to avoid stuttering with TrueHD on some audio devices
Download: Installer (both x86/x64) -- Zips: 32-bit & 64-bit
Download 3D Plugin: 32-bit & 64-bit

H.264 MVC 3D Support

This version introduces support for decoding H.264 MVC 3D streams, as found on 3D Blu-rays (or in MKVs created from those Blu-rays with MakeMKV).
LAV Splitter supports reading H.264 MVC from Blu-rays directly, when opening a Blu-ray SSIF file, or from MKVs. Note that MVC in MPEG-TS which is not created Blu-ray compliant is not supported at this time.

To enable decoding of the H.264 MVC extensions, an external decoder plugin is required, which the Installer will automatically download if the appropriate option is set, or which you can download manually from the links above (place in the same folder as LAVVideo.ax)
LAV Video currently does not allow "processing" the 3D video in any way, it can only output it to a 3D aware video renderer - madVR 0.90 or later. In the future it might be possible to have LAV Video render the video as Side-by-Side, but not in this release.

The interface to receive 3D video and accompanying metadata is documented in the developer info package, if other renderer developers want to support this.

HEVC HDR support

Also new in this release is the ability to export the HDR metadata from HEVC HDR streams. This metadata is automatically send to the video renderer, so it can render the video properly. This is available with madVR 0.89.18 or newer.
LAV Video does not process the HDR information in any way, and any video renderer unaware of HDR will still render the typical "washed out" image.

The interface for the HDR metadata is also documented in the developer information.

DXVA2 VP9 Hardware Acceleration

Late last year Microsoft published a specification on VP9 DXVA2 hardware acceleration. Shortly after, both Intel and NVIDIA started to support this in their hardware.
This version of LAV Video enables using the hardware acceleration in the latest NVIDIA GPUs (GTX950/960), and recent Intel GPUs (Braswell and Skylake)

Please note that only VP9 Profile 0 is supported, 4:2:0 8-bit.

There is more!

On top of all these features, LAV Video also added a new deinterlacer, Weston Three Field Deinterlacing Filter (w3fdif), which can achieve quality similar to YADIF at much higher speeds (simple on 32-bit, complex on 64-bit)
For multi-GPU systems, you can now choose which GPU DXVA2-CopyBack should use for decoding. Please note that only GPUs with a connected display are available (Direct3D9 limitation)
And of course there is also a list of stability and bug fixes that may not even have made the changelog.

Enjoy one of the bigger LAV releases of the recent past, and have fun!

PS:
The download links have switched to HTTPS, if you're having trouble with access due to an old browser and/or OS (I'm looking at you, XP users), you can manually switch the URL back to HTTP if you must.

This will be the first "stable" release with w3fdif to recommend for DVBViewer users, to test different deinterlacers regarding speed and quality.

The only annoying part of "TV on a PC" are the flickering top and bottom lines. They are not always encoded cleanly by the broadcaster. I wonder how to treat them in a special way; but I know you have never been a fan of implementing post-processing filters, pure decoders only...

Thanks for the release.

I remember talking about "VP9_VLD_10bit_Profile2" support and adding this info to a nightly build.

Still no hardware that exposes this, and Microsoft actually updated the spec again and removed it again.

Quick question:
Is the ArcSoft dtsdecoderdll.dll still supported?

Yes, but I don't really consider it useful anymore. The built-in DTS decoder has proven to work quite well, and if there is a sample where it doesn't work, we would love to get a copy.

The only thing it doesn't support yet is DTS Express (which is its own little codec, not much to do with the remainder of DTS), but those are commentary streams only, and rare at that.
But someone was actually working on DTS Express decoding, so it may show up in the future as well.

Anyway, as long as it doesn't start causing problems, no reason to remove it.
