Problem with "LAV Splitter Source", on these [HLS]-LIVEstreams it didn't output the highest possible quality for video stream:
http://85.238.112.40:8810/hls_sec/on...st-renome.m3u8
http://85.238.112.40:8810/hls_sec/online/list-ont.m3u8
https://strm.yandex.ru/kal/zvezda_su...a_supres0.m3u8
https://strm.yandex.ru/kal/fresh/fresh0.m3u8
and on these [HLS]-LIVEstreams it can't even connected:
https://strm.yandex.ru/kal/zvezda/zvezda0.m3u8
https://strm.yandex.ru/kal/euronews/euronews0.m3u8

Any feedback would be appreciated.

forgive me magnanimously, if it's inappropriate, I won't do it again. I only tried to thoroughly describe a problem that really annoys me, so in desperation I stopped watching the HLS-LIVEstreams at all.

You should probably use software thats actually designed for playing live streams, if you want an actual decent experience. LAV Splitter is designed for file playback first and foremost, and thats always going to be the main focus of its development and my time.

@nevcairiel. I think I found a bug. HDR no longer works properly in 0.73.1. I get distorted video when displaying any HDR file. Problem goes away if I roll back to 0.73.
I first noticed it when launching HDR videos in MPC-HC v1.8.3 which has LAV Filters 0.73 built in.
MPC-HC would work fine but MPC-BE, which was configured to use LAV 0.73.1 would fail. Took one more step and over-write MPC-HC with 0.73.1 and it starting failing running HDR videos as well.
I'm Running latest madvr, Windows 10 64 Pro ver. 1803 and latest nvidia drivers. (2080 Ti)

There is literally only two changes in 0.73.1 over 0.73, and if the one affecting video breaks HDR for you, then your HDR file has broken metadata.
A sample file would be needed. Alas HDR still works for many other people.

I confirm that 0.73.1 works fine here with HDR using MPC-BE.

Thank your for the response!

Weird thing with software... I repeated my tests using known, good HDR video files, same results.. working with 0.73 and not with 0.73.1.

However... decided to take the "nuclear" option, completely removed LAV, both MPC-HC and BE, madvr. Used DDU to remove Nvidia drivers (which is something I always do when installing new Nvidia drivers). Proceeded to re-install everything, rebuild profiles, etc.
Now HDR is working for me with Lav 073.1 on all HDR files I have.
It is just weird how consistent the failure was prior to re-installing the drivers and programs. Go figure!

Using a new PC with Win x64 October 2018 and a Skylake i5 6500 (HD 530) I couldn't make it work with LAV filters for hybrid VP9 acceleration (DXVA2 native VP9)

It falls back to SW.

Latest versions and updates for everything.

Does it work ?

I've ticked wmapro in the LAV Audio formats page but I still get MPC-BE choosing the WMAudio Decoder DMO for pro V9 files, should this happen?
Having this decode causes stuttering on seek so I have to set MPC-BE's internal decoder for this format.

It depends how you've setup LAV in MPC-BE. If you've set them to be the preferred filters, it should work. If not, then the MS decoders may have a higher merrit. You could also block the MS decoder on MPC-BE and it should then use LAV.
Personally I just use LAV as the preferred decoders in MPC-HC/BE. Some people don't recommend doing that, but if I want external LAV for everything, I don't see why I shouldnt.

I'm usually (why not always read lower in this post) too. Because only last version of MPC-BE begins showing video with half-height H265 files but quality without script is worse (with script equal) then with external LAV Video Decoder.
My script https://forum.doom9.org/showthread.p...67#post1850467 for ffdshow raw works well enough in SmartDVB already (due to implementing LAV Splitter in it) too so I can watch such SAT channels directly from SAT in almost maximum (I'd prefer hardware deinterlacing over yadif x2 in script but don't know how reach it) quality.

MainConcept is working on half-height files supporting but ffmpeg seems not. This is answer on my yesterday's request - I'm sure it's not a secret:
The file you sent us 20180923-225044_CT 24.ts (17MB) https://yadi.sk/d/BfOGlnU7Ftir0g is interlaced. - I know that
We support this in new version of HEVC Video Decoder (v.10.0).
This new SDK version is under final testing now and it'll be available soon...

Btw only MainConcept HEVC Video Decoder due to decoding only key-frames shows first 8K test from Turkish SAT - half-minute record 20181024-132601_TURKSAT_8K_TEST.ts (307MB) https://yadi.sk/d/70tUNE7oK21xfA and longer than minute 20181024-222320_TURKSAT_8K_TEST.ts (761MB) https://yadi.sk/d/7ALFkaKuIMUfRA
I'm not only one who want this feature http://smartdvb.net/bb/viewtopic.php?f=13&t=1699
PS. Elecard with Skip Non-key setting:
REGEDIT4

[HKEY_CURRENT_USER\Software\Elecard\Elecard HEVC Video Decoder\SmartDVB.exe]
"Quality"=dword:00000001
shows that 8K well too.

@nevcairiel

Any news regarding VP9 hybrid support of Skylake ?

Do you have one to test it ?

No, I don't have a Skylake CPU. And as a general answer, LAV has no conditions to check for hardware compatibility (at least not for VP9), it'll just try to open the device in the videos resolution, and if it succeeds, then it'll use it.
Hence if its not being used, then opening the device did not succeed.

The closest I have is a Apollo Lake NUC with a 9th Gen HD500 GPU, but I don't know if there are any media differences between that and Skylake (even though they were released very close to each other and are both 9th Gen).

Apollo Lake NUC has full hardware decoding support for HEVC and VP9 for both 8bit/10bit, so it's a lot different and closer to Kabylake's GPU.

It should work for that GPU.

I'll try different drivers, probably.

Thanks.

Apollo Lake has no 10-bit VP9 ability, Gemini Lake does.

Just found out an ancient post of you (late 2015) at benchmark thread.
You owned that time a Skylake NUC and ran a VP9 DXVA2 benchmark too
