LAV Filters - DirectShow Media Splitter and Decoders - Page 1167

I saw that they released it, and I've updated my toolchain to it.

@nevcairiel
by the way, the link to the 3D plugin on page 1 is still pointing to the old 2.7....

nevcairiel · 28th February 2019, 23:40

The links will be updated when a new release is available that uses the new version.

I need to 'bump' this because I noticed another problem !
Film: JUSTICE LEAGUE (German UHD)
MPC-BE with LAV filters

Playback hung every time in the same place. So first measure was to carefully clean the disc to remove dust or whatever.
But the problem was still there.
Now I thought that the disc was defective but to my surprise VLC played it without any problems !!

So I blocked 'LAV SPLITTER' in BE and now the movie plays fine !! Nev, do I loose anything if I keep 'LAV splitter' blocked ??

If you search the thread you'll find posts by nev explaining the difference: splitter source opens the file itself to read from it and demux, while splitter only demuxes the data it receives from the system file reader filter ("file source async") that is used to read the raw data from media.

Grimsdyke · 1st March 2019, 19:07

O.K., but why are 'Splitter' and 'Splitter Source' messing things up during playback ??

el Filou · 1st March 2019, 23:23

No idea.
I think nevcairiel has said that Splitter Source is 'the old way' to read files, but at least in my experience it's more stable.
On my system I had to force use of LAV Splitter Source with MediaPortal because otherwise it would sometimes crash to desktop when using File Source Async + LAV Splitter when starting playback of files.

Hi all.
With LAV Filters 0.73.1.19-git madVR's ivtc algorithm stopped working on 29.970 video.

huhn · 4th March 2019, 17:15

can you try 0.73.1.28?

if this still doesn't work i will try to reproduce it. still don't even see a new way how lav filter can stop madVR from running IVTC.
so just to be sure it doesn't work with native decoder it needs copyback or software decoding.

Of course. Same issue.
ivtc
no ivtc

IVTC is not supposed to be used after YADIF it's supposed to replace it.

use it on interlaced telecine streams not deinterlaced streams.

Will be the same. Checked.

sneaker_ger · 4th March 2019, 18:58

I don't really understand. madvr's IVTC has to be enabled manually, does it not? LAV doesn't detect telecining.

And why are the colors in the screenshots different?

Yep. Force film mode enabled.
Ask AMD. Screenshot 1 - 19.1.1 Radeon software, 2 - 19.2.3. This is all the difference.

I don't have any NTSC material to test but with my PAL film material madVR's IVTC still works with LAV 0.73.1-28 and detects 2:2 cadence.

You can download it from here (1GB) or here.

Megalith · 5th March 2019, 18:59

Is it normal that LAV Audio isn't activated for LPCM surround tracks?

nevcairiel · 5th March 2019, 19:19

If its used or not is ultimately up to the player. But if it uses standard graph building rules, then it'll only insert filters if it actually needs them. And if the audio is already PCM, then it doesn't need a decoder.

LAV outputs the stream as progressive, that's why (if you set LAV Deinterlacing Mode to Force, madVR's ivtc kicks in and detects 4:2:2:2 cadence).
Maybe an ffmpeg update caused this?

nevcairiel · 5th March 2019, 20:43

As far as I can tell, that stream is actually progressive. MediaInfo also agrees.
