Alex,
is this renderer available as a standalone filter for 32-bit apps?

Yes, grab the 'standalone_filters' package from the usual nightly locations.

LAV Splitter file buffer size settings

Hi LAV Splitter developer,

Please can you consider adding better/more advanced options for setting the file/network file buffering size (like we can set in VLC media player)???

We want to be able to set the EXACT file buffer size in ms or RAM MB (not just the maximum size which we can currently control).

This would help a lot for playing Windows networked video files.

Thanks for consideration!!!
Thank you

Can anybody say is h266 (Versatile Video Codec - VVC) supported by ffmpeg (or plan to support in nearest future) so it can be implemeted in LAV Video Decoder?
I'm asking because (seems) first FTA (so not encrypted) 8K SAT channel The Explorers UHD translation in this h266 (VVC) codec is beginning from 28e2 11973v31000 (I can't receive it personally but hope to get record so I'd want to watch that

VVC is not even fully standardised yet, let alone any hardware decoders available - best you will manage is the decoder in the reference software for the time being.

Thanks for reply.
Btw The Explorers UHD seems just 4K (not 8K).

It's strange that they're already testing it on a satellite https://www.sportsvideo.org/2020/06/...ding-standard/ when it's still in draft status (even if late draft) https://mpeg.chiariglione.org/standa...e-video-coding. I think that was a private test and it's not meant to stay.
MediaInfo can't even read the metadata.

I can't see any reason why it wouldn't work if packed within a data container format already familiar to the satellites systems, which I would assume to be MPEG 2 TS unless things have changed with newer 4K transmission standards.

IMHO testing on SAT proves h266 VVC will be new SAT encoding standard.
May be someone know where we can download OpenVVC decoder developed by IETR from?

sure: https://vcgit.hhi.fraunhofer.de/jvet/VVCSoftware_VTM
just hope it's the same old version as your stream and bring a lot of time.

FFmpeg and Dav1d update please

FFmpeg has had some header refactoring and other stuff moved around. So some adjustments to custom LAV patches are needed after rebase (move avisynth headers/mkv font mimetype/fraps/fix h264 sps patch). Better to catch regressions early.

Thanks for the quick update!

The VP9 ConfigBitstreamRaw workaround also needs to be applied in FFmpeg dxva2.c

Could you have a look at this hang in LAV:

And another issue:
https://github.com/clsid2/mpc-hc/issues/434

And a flac file with playback issues:
https://www.sendspace.com/file/2oxerj
Beginning is wrong. Seeking back to begin also doesn't work properly.

And a hang issue with DVD:
https://github.com/clsid2/mpc-hc/issues/464

Could you check if this is a LAV issue? It doesn't happen with Microsoft's MPEG-2 decoder.

It does not. That code is never executed.

The H.264 MVC decoding option is still experimental from what I've read. In what circumstances should it function? It seems my CPU is recent enough to support it (i7-5820k), but this option resets to unchecked every time I enable it and restart MPC-HC. I use madVR with D3D11 exclusive mode.

You need Intel graphics, not a Intel CPU. Yours does not have a built-in Intel GPU.
On Desktop CPUs I would probably advise against using it anyway, decoding 1080p H.264 isn't that complicated, and it avoids conflicts and problems.

If you're using the MPC-HC built-in LAV Filters, it may not be saving the option properly.

VP9 decoding using AMD GPUs doesn't work with 0.74.1.57-git
only d3d11 native has been tested.
