LAV Filters - DirectShow Media Splitter and Decoders

[AngelGraves13]

Will you be adding DirectX 12 copy-back mode support?

MPC-BE just added it, so I'm guessing it's not far behind for LAV.

From MPC-BE 1.7.0 notes
"Added support for D3D12 copy back mode"

[nevcairiel]

For Copy-Back in particular it doesn't seem to have major advantages. Why would you want to use it?
The only reason to support it would be if a video renderer use D3D12 and wants interoperability - eg. in Native mode.

I'm noticed that I have no such issue when playing it on my PC through VLC.

Any feedback would be appreciated.

There must be a benefit otherwise why would someone go to the trouble of programming it?

I'd be more interested in a DX12 "native" mode, to be completely honest.

maybe ask them.
there is even a lavfilter version with dx12 and a mpcVR that is DX12 if any of these are native is beyond me.

FFmpeg is dead, use Librempeg where this have been fixed ages ago.

I named a reason why someone might want it. There is just no demand for that in LAV.

Video decoding is ultimately just an API to access the video decoding hardware. There is no huge difference what you use - so what it comes down to is what something else uses that wants decoding. If that uses D3D12, then you use a D3D12 decoder. That's all.
Noone has made an actual D3D12 video renderer, or approached me about supporting it for that. This is not a user-relevant feature, but would only benefit another video renderer that wants to run in D3D12.

As for a video renderer - if all you do is use simple shaders and using D3D Video Processing, there is no benefit in D3D12 anyway, you only get a lot extra complexity for no benefit. Only once you start using much more complex shaders, compute shaders in particular, would there be any benefit, as D3D12 gives you access to the newer shader models.

Where are Librempeg binaries downloads for Windows ?

Perfect play with ffmpeg + https://github.com/xiph/speex.

Compile it!

That library is highly under optimized, do not use.

Without any public download of libraries for Windows the use of Librempeg will be very marginal.

Sure, keep using buggy software that is build by random guys.

Алексей приветствую,
спасибо за отклик! Почему всё так сложно?
Есть ли возможность прикрутить то что ты посоветовал(или AviSynth+) к DirectShow плееру?

Compile it yourself and offer binaries to the world. If you don't then you will miss the vast majority of Windows users who also are the vast majority of computers users.

В mpc-be на встроенном декодере это уже и так прикручено. Можно взять его, а можно просто взять декодер, он доступен в виде внешнего фильтра.

Can you build a GCC 13.3 MinGW pack?

Why - there is already a gcc 14.1 release.

[clsid]

GCC 14.1 is fine too. In past I usually skipped .1 versions but I guess there is little reason for that nowadays.

And possibly another FFmpeg update for the addition of xHE-AAC decoder would be awesome as well.

[LigH]

The reason GNU starts with .1 releases today is that everyone started to skip .0 releases...
