What was the last version of LAV Filters that supported Windows XP with Service Pack 2?

Last release to support XP was 0.70.2, no idea exactly what nightly build between that one and 0.71.0 removed support.
Edit: it needs SP3. I really have no idea why so many people insist on running an even older Service Pack on an already obsolete OS.

I have added the collection type in the latest ffmpeg update, thanks!

I have a couple of questions about the LAV video decoder's "Hardware decoder to use" setting.

If a hardware decoder setting such as DXVA2 native or DXA2 copy-back had been selected and saved, what does the LAV video decoder do if the actual hardware is no longer available - say it has been removed or the driver becomes disabled/faulty ?

Does the LAV video decoder just fall back gracefully and silently to software decoding (equivalent to the "none" setting), or does it get into an error state ?

Also, if I understand correctly, the D3D11 setting is just for use with the MadVR renderer which can use DX11. With the D3D11 setting saved, what does the decoder do if it is connected to a renderer than can only do DX9 (such as EVR) - does it drop back to software, or DXVA2 native, or DXVA copy-back or something else?

If a previously used GPU is no longer available, it will simply pick the first available one.

D3D11 decoder also works with D3D9 renderers. But it will work in copyback mode.

Thanks. So if for some crazy reason it can't successfully use a GPU, will it always drop back to software mode rather than abort with error?

If your selected GPU is not usable, it'll use the primary GPU, and if thats also not capable of decoding, it should switch to software.

Do note however that fallback from DXVA2-Native to software is a bit limited in some situations, but in this case when the GPU isn't usable at all, it should probably manage.

it will use software in this case with no error code which is equivalent to none.

madVR runs in d3d9 it only accepts the frame from d3d11 and has limitations with it. mpc VR has "full" d3d11 scaling and even deinterlacing works too and it is a d3d11 renderer.

Which is nice, but doesn't really matter. The other capabilities of a renderer is where it counts.

sorry i have to disagree it matters if you can play interlaced content or not.
the more renderer that support this completely the better so hopefully madVR joins in and gives it the support it deserves.
not a problem in lavfilter anyway which is important here.

Which are the D3D11 renderers that work with LAV's D3D11VA decoder in native mode ?
MadVR only ?
Is there any MS renderer of latest Win10 compatible with LAV's native D3D11VA decoding ?

wrong thread.

mpcVR supports it (even in d3d9 mode it uses native just like madVR) with d3d11 processing but it's still yung and madVR only accept the image from it and uses d3d9 after that.

no clue about the rest.

mpcVR ?
I missed that project!
Very interesting as I read now and kudos to @Aleksoid1978.

Does it currently work only using MPC-BE and its internal filters ?
Could someone install it and use it with MPC-HC and internal LAV filters ?

why don't you ask them in the mpc-be thread? for some reason they post new version in that thread not in a new one.
it's fully supported in mpc-be.
you can make it work in mpc-hc (i personally test it in there) but some feature don't work they need player support.

d3d11 native decode works perfectly with mpc VR so lavfilter is supported.

using mpc-be with lavfilter is pretty normal lavfilter simply has a bigger feature level.

in the end it is directshow and so it should work fine with ffdshow too.

Thanks a lot! Though perhpas these additional supports are superficial and trivial for developers, I really appreciate it.

(Background) Historically there were no official mime types for fonts, but lately they were officially registered as CSS @font-face has become so common. The mime type changes (legacy -> standard) are causing subtle problems, since embedded fonts are recognized by their mime types stored in MKVs. Players that can't handle new mime types can't show styled subs properly, in the worst case subs being totally unreadable!

I checked LAVFilters-0.74.1-28. I could not cause freezing after pressing the Stop button. Thank.
