LAV Filters - DirectShow Media Splitter and Decoders - Page 991

Please open your own thread if you want to continue your discussions, its entirely unrelated to LAV at this point.

DragonQ · 18th October 2015, 16:13

Nev, are there any features you're looking to include before the release of 1.0? Just curious, as it seems LAV Filters is really stable at this point and not much is blocking such a release except features.

nevcairiel · 18th October 2015, 23:02

I don't put much meaning in such version numbers. I don't have any concrete plans when or what to do specifically for a 1.0. Maybe one day it'll feel right, and I'll use the chance to re-do some of LAVs control interfaces (a bunch of cruft accumulated that I never removed because of backwards compat).

Anyone?

After "Switched ASF/WMV demuxing to a new demuxer from Libav", the splitter no longer plays all of my wmv's. "wm asf reader" is used instead when that happens. I went back to 0.65.0.25 and it can handle all of them. The ones that are having problem shows "... unneeded bytes at end of file" in gspot. Trying to fix the wmv's index might fix the problem, but I will no longer be able scan for duplicates and some are on read-only media. Can you make LAV Splitter fall back to the old demuxer when that happens? Thanks.

nevcairiel · 20th October 2015, 18:34

Please provide samples that don't work instead, that way they can be fixed instead of worrying about some fallback.

I don't currently plan to offer every kind of unusual speaker setup in the options, it would just overwhelm the list.

If you really want to, you can cheat the options box by editing the channel layout in the registry entry (HKCU\Software\LAV\Audio -> MixingLayout), 3.1 would likely be hexadecimal 0x0F (0x1+2 for L/R, 0x4 for C, 0x8 for LFE)
Maybe I should add a custom option and let you specify hex channel layouts in the options panel, huh.

Thanks nevcairiel will take a look.
Will using the hex values allow the sliders to vary the mixing of the back/side L/R channels into the front L/R?
The ffdshow custom matrix mapping/mixing tab is probably overkill, but still a nice flexible solution IMHO.

I just found Equalizer APO, which has support for reordering and regaining channels, although it requires you to set each channel's gain manually, and cannot mix multiple channels into one. It doesn't support compression/limiting, because the author is mostly all about EQ, but with some prodding it could happen. Still, it's easy to get in the chain. This is the kind of thing DirectShow was made for; LAV shouldn't have be the whole audio chain end-to-end.

There must be other filters out there that do generic audio processing well. Better to discover them than beg nev to do something he won't.

nijiko · 22nd October 2015, 16:47

Will LAV be planed to support BD ISO image / folder or BD navi / menu?

nevcairiel · 22nd October 2015, 16:56

No plans.

After a jump in the timeline you see the screen.

I managed to get ahold of Homeland Season 3 DVDs which you said also had this problem (and their IFO files match the files you send me), and I cannot reproduce any problems. I'm playing from the original DVD in the drive, and all is working fine.
Latest nightly, of course.

clsid · 23rd October 2015, 16:17

Maybe related to the Windows update?

OK, thanks,
I will try it with the Latest nightly.

With another DVD(series) "EUREKA" there are no problems.

EDIT: it works with the latest nightly!

Nev

Is it possible to put release notes on nightly builds so we know what to test?

Thanks

If there is something in particular I want tested, I'll usually mention it.
Otherwise you can read the commit logs:
https://github.com/Nevcairiel/LAVFilters/commits/master

I'll not write a proper user-readable changelog for the nightly versions otherwise, sorry.

There is no VP8 or VP9 hardware acceleration in LAV Video of any kind (yet). The main reason for this is that until recently there was no specification on how to access the VP8/9 hardware decoders. Microsoft has released this specification recently, so now all we have to do is hope that new drivers show up which actually implement hardware acceleration compatible to this spec. For VP9 its at least possible on Broadwell, Braswell and Skylake (and I have this nearly finished implementing in LAV). Haven't seen any VP8 support exposed in drivers yet.

And Nvidia?

Hi nev,

I see that you changed the wmv splitter in LAV .66. I have many wmv files that will not seek and/or play now with .66 but worked fine with LAV .65 so this leads me to believe that this new wmv splitter (Changed: Switched ASF/WMV demuxing to a new demuxer from Libav) perhaps isn't quite ready for general use yet (?). I have included two samples here (I have many more but they are much bigger to upload) : http://depositfiles.com/files/nksp2h699

Note: This should be easy to duplicate... I have LAV .66 set as wmv splitter and LAV as wmv decoder and the sample vids won't seek and or play. As soon as I switch the wmv splitter in Zoom Player to WMReader or use LAV .65 as the wmv splitter the files play and seek fine.

Thank you

sneaker_ger · 25th October 2015, 19:28

Have you already tried the latest nightly (0.66.0-31)? If so, provide samples.
