can EVR-CP/madVR not handle this?
Prores videos are mostly 4:2:2. How to output 4:2:2 as 4:2:0?
EVR-CP or plain EVR, same issue Haven't tried madVR yet.

Well, I tested Intel HD4600 and it has no issue at all, blaming Nvidia for outputting 4:2:2 badly xD

Interesting that Intel can de-interlace in RGB32 mode but Nvidia
I can upload a short sample if you're interested in

Now another topic about Inverse Telecine/IVTC pulldown, Nvidia GTX960 vs Intel HD4600

Intel has very bad IVTC, sometimes works and sometimes not at all

it is technically not possible to deinterlance a 4:2:0 source that is transformed to RGB the image is scaled vertical so it can't be deinterlanced anymore. (well there is a very a technically way to do that but... complicated and unnecessary)

so RGB deinterlancing support is just bad.

if EVR-CP can handle 4:2:2 correct you should report this to MPC-HC/BE.
EVR normal has nothing to do with that.

you can force 4:2:0 by disabling everything that is not 4:2:0

Problem With PCM EAC3 Track of 'Brave' Bluray

The Brave Bluray has a EAC3 track (French language). When I set Lav Audio to bitstream, my receiver displays Dolby Digital Plus +7.1. If I change Lav Audio to PCM, however, the receiver shows Multichannel 4.0 track. I know it's not an issue with my receiver or Lav Audio settings because with other Dolby Digital Plus 7.1 samples my receiver correctly shows Multichannel 7.1. Any ideas?

LAV Filters 0.70.1
Code:
LAV Video
- NEW: DXVA2-CopyBack uses D3D9Ex to allow headless operation
- Changed: Increased the maximum number of decode threads to 32
- Changed: Rebalanced the "Auto" thread strategy to use the exact number of available CPU cores, instead of 1.5x the cores
- Fixed: Certain H264 streams could crash in 0.70 due to lack of buffer padding
Download: Installer (both x86/x64) -- Zips: 32-bit & 64-bit

Check the 0.70 release notes for additional details.

DXVA2-CopyBack Headless

Using D3D9Ex allows using DXVA2-CopyBack decoding on the primary GPU of headless systems. Note that this only allows using the primary GPU on entirely headless systems, secondary GPUs without an attached screen are not available. This helps on media server systems to utilize DXVA2 for transcoding, for example.

Threading changes and benchmarking

LAV Video 0.70.1 rebalances the "Auto" threading strategy to use one thread for every available CPU "thread" (ie. real cores and virtual cores). Previously, LAV used 150% of the CPU threads to slightly boost benchmarking, however playback results have shown that overly taxing the CPU can cause playback glitches that wouldn't otherwise be present.

When you are benchmarking, this change should be kept in mind, and if needed the thread count adjusted manually to achieve comparable numbers.

In addition, the maximum number of threads (both in auto and manual) has been increased to 32 (from 16), to allow utilizing upcoming new CPUs with higher core counts.

PS:
It may be possible that this is the last version to work on Windows XP. I'm working on some new module that requires D3D functionality thats not available in the Windows SDK used when building with XP support, and using a newer SDK automatically removes XP support.
More details on this will follow as this feature is being developed.

Knowing that you are an Intel guy, you should put max. threads to 36, according to the latest HEDT CPU Extreme Edition (XE) from Intel (18C/36T) and not 32, following AMD's HEDT CPUs - Threadripper 16C/32T

Unless of course you are like me and you don't believe that this thing - 18C/36T - can be delivered on time, later this year according to Intel

There is actually a 32 thread maximum limit in a few decoders, so going over that and introducing inconsistent behavior didn't seem very ideal.
Also, 32 is a much nicer number, being a power of 2 and all.

But no, I don't believe that CPU will likely launch this year (even though its basically just an existing CPU out of their Xeon lineup anyway, its not like they are making something new). Makes no huge difference to me either way, not something I would buy.

has anyone been able to successfully output AAC 5.1 audio with LAV?

I'm running Kodi Dsplayer, with a 5.1 setup, and everything works properly (DTS, AAC, PCM, etc), but if the audio source is AAC, somehow it gets converted down to 2.0.

Windows is configured as 5.1, LAV is using default settings. I tried outputting to "default audio device", to "directsound: default audio device", to "Onkyo TX-NR709", all give the same result.

If I output to reclock, and use WASAPI, then it works fine (AAC 5.1 comes out as 5.1). If I use Sanear, same problem, 2.0 output.


Any ideas?

LAV Filters 0.70.2
Code:
LAV Video
- Fixed: DXVA2 decoding could fail in 0.70 after a dynamic media type change
Download: Installer (both x86/x64) -- Zips: 32-bit & 64-bit

Check the 0.70 release notes and 0.70.1 release notes for additional details.

One regression fix for DXVA2 decoding in 0.70 which mostly occured with TV playback, as type changes are not common in file playback.

PS:
I originally posted this in the 0.70.1 notes, but to increase visibility I'll repost it here:
It may be possible that this is the last major version to work on Windows XP. I'm working on some new module that requires D3D functionality thats not available in the Windows SDK used when building with XP support, and using a newer SDK automatically removes XP support.
More details on this will follow as this feature is being developed.

Note that this is only meant as an early information. I do not plan to debate this. If new features turn out to really require this change, then it will happen.

Are you using a SPDIF connection to your receiver? That is limited to 2.0 for uncompressed audio (PCM).
You either have to use HDMI connection or re-encode to AC3 audio (which is what reclock does).

I'm using HDMI, and I'm not re-encoding to AC3 with reclock, so the output is 5.1 uncompressed PCM, and it works fine, the only major difference being that Reclock uses Wasapi.

does it work properly with MPC-HC?
can you check the lav audio status or even make a screen when the problem happens?

You mentioned sanear: try out MPC-BE wasapi implementation (it's not the same as sanear) since sanear has a big bug regarding to the channel numbers.

Not for discussing, but I believe it will be great before stop supporting WinXP release version of LAV Video Decoder (i.e. 0.70.3 or later) which can hardware decode h265 4K 10bit via NVIDIA CUVID in WinXP?

I will not spend time on XP support. I have made this point quite clear in the past.

Problem with "LAV Splitter". I can't playback these TV-streams:
http://event.radio-satisfaction.de:8550/;
http://81.169.229.251:9500/videopromo
Through players[VLC as example] which didn't using LAV i can hear only audio.

Any feedback would be appreciated.

Problem with "LAV Splitter Source". From this radio-stream i got metadata("Now playing" tag) but only through RTMP-protocol, why HLS-protocol didn't show this metatag in Zoom Player? Examples:
rtmp://wse.planeta-online.tv:1935/live/channel_13
http://wse.planeta-online.tv:1935/li.../playlist.m3u8

And why RTMP-protocol not enabled by default in installer? It works without any trouble.

Any feedback would be appreciated.

Problem with "LAV Splitter Source" metadata delivery for all Opus & Vorbis IceCast streams. "get_AuthorName" and "get_Description" functions work but the "get_Title" function fails[The error code is 0x80040216]. Examples:
http://209.126.66.166:10999/192.opus
http://209.126.66.166:10999/192.ogg

Any feedback would be appreciated.
