It is very unlikely that there will ever be a Media Foundation version of LAV Filters.

You can find additional free Media Foundation codecs (from Microsoft) in the the Windows 10 store. For example HEVC, VP9, AV1, and MPEG2.

You can? Because outside of the initial post asking if there was an SDK, the thread is locked and the only reply says to post the question somewhere else.

I updated AMD Driver to 20.4.1 for my RX 5700 and when playing this file - https://4kmedia.org/lg-chess-hdr-demo/ I get about 90 dropped frames right at start of playback. I think this was introduced with AMD driver update to 20.4.1
I use MPC-BE v1.5.5 build 5165 with madVR 0.92.17 and LAV Filters 0.74.1-34. If I disable/block external LAV Filters completey in MPC-BE and use its internal filters it is fine.

So I think AMD changed anything related in Driver which is causing this behavior in LAV Filters.

If you need any further info, let me know.

guys i'm not sure if it's the right place to post but is it possible for lav filters's developer to develop an import plug-in for adobe premiere pro? (works on adobe media encoder too)

It is extremely rude to ask that. Why the fuck should he invest his free time in developing something for a commercial product from Adobe? Go complain to Adobe that their software sucks.

they only cares about pro codecs, not all codecs and rare ones like bink video!
adobe like all only thinks about themselves.
i'll pay for the plug-in if he develops it.

I think you should try AviSynth with FFmpegSource and PremiereAVSPlugin.

thank you so much, but that premiere plug-in is very old & outdated. (doesn't work with latest premiere pro cc)
we premiere pro users need something new & great like lav filters for premier pro cc.

I'd like someone to review a certain file encoded with x265. Or encoder settings.

File: https://mega.nz/file/5qoBFIqS#c_OjQO...gHok4ZEsHHdiiU

The problem: I'm getting very bad fps - 15-20 instead of 24. Changing settings in LAV Video didn't help. Switching to ffmpeg decoder helped.

Here is how it was encoded:

Someone mentioned that bframes=16 could be the problem.

I'd like to know why switching to FFmpeg solves the fps issue, and what can be done with LAV to work better with this case. Hw acceleration is still disabled in both decoders from what I see.

Also, any comments about encoding settings are welcome.

Hi!

Probably a stupid question, but how do I verify if the MVC codec is successfully installed. If there's any visual feedback it's too fast for me to see.

Any way to test if it's working without a 3d screen? (So I can get it working by the time the screen is acquired.)

by playing a 3D file with a player that supports it.
or by checking the decoder is present in the lavfilter folder.

What file should I check for? Playing a file produces a plain 2d output so that doesn't help.

The mvc decoder file is: libmfxsw64.dll
Should be in lav folder or in system32

It's there in the LAV folder.
So far I couldn't get 3d output though. Potplayer even has anaglyph options for 3d. But so far I couln't get anything.

Okay. So it seems madVR was the problem. So the decoding seems to work at least.
(Whether I can get it to work with an actual 3d display remains to be seen.)

just to make that absolutely clear.

you are ware that "no" new displays support 3D for a couple years now and that 3D is discontinued on nvidia.

unfortunately, that is true, although a lot of fantasy and Sci-Fi movies are still presented in 3D...
but there are beamers...

Hey nev,

I've recently run into this problem.
I have a few foreign files that have the ENG SDH subtitle as 1, and the regular ENG subtitle as 2.

The relevant part of my advanced config is this, basically when there's no ENG audio then load ENG subtitles (the last step there):
eng:eng|f eng:0ff *:eng
So what I get is subtitle 1, the SDH one. I would like the splitter to choose the regular ENG, e.g. subtitle 2.

Would it be possible, in the Lav Splitter configuration, to incorporate a button placed beneath the "Prefer Audio Streams for the Hearing/Visually impaired" called something like "Disable/Remove Audio Streams for the Hearing/Visually impaired"?
If that is possible to code, obviously. Would be great.

Or if you have other suggestions on how to solve this issue, the post I found was from 2015 and to be honest I have not read through the whole thread, it's a lot of posts.

Thanks.
