It seems to be because the menu buttons coordinates are based on 4/3 and when LAV (or is it the player?) stretches the menu to 16/9 for proper AR, the new buttons coordinates aren't "reflected".
For exemple, with such problematic widescreen menus, if I force the Aspect Ration to 4/3, then every button on the menu works [clicking right over the buttons work].

Unless this doesn't happen with another decoder, its a player or renderer problem. I don't think its the decoders fault, because it doesn't position the clickable areas, the only possibility would be if the decoder gets the AR wrong, but does it look wrong?

The sample gets to about 3 seconds in, and then just stops playing. It also locks the player, so Task Manager is required to kill it.

Plays just fine for me, with any decoder, software, CB or Native.
Considering the HW decoder doesn't work with this sample on your system, it would fallback to software, and that mode also works just fine for me.

Thanks nev. Just tried it with EVR, and it works ok. Looks like it only locks up when madVR is used. I will pop into the madVR thread and report it there.

Maybe it depends on the video drivers?

EDIT:

I spoke too early

, now that I've made sure LAV Video is actually used by WMP 11, yes, it works only when YADIF is enabled, and the subtitles don't appear at all.

But this all is not very-important, because I don't like to use WMP 11.

The sub/menu issue is because ffdshow is stealing the subtitle pin. I will see if I can get that fixed.

@nevcairiel
Could you consider adding a workaround to enable Yadif for this combo?
DVD + WinXP + wmplayer.exe

Nev has no interest on XP though 70%+ people in China stick to XP.

It's simply outdated, even many game developers don't support it (DX9) anymore.

I couldn't agree more. I got rid of XP three years ago myself.

But you know..

filler56789 · 25th November 2012, 19:01

Except that in this case, the actual problem is in Windows Media Player 11, not in XP itself.

And let's try to go back to the topic.

In DXVA checker this egur's test clip plays fine using my HD3000 and MS DTV-DVD video decoder. But with LAV filters and DXVA2n video is corrupted. The same is for MPC-BE.

Use the QuickSync decoder for Sandy Bridge or Ivy Bridge GPUs.
Using DXVA is not recommended, because Intels HW implementation is somewhat different (and Intel doesn't actually say different how), this is especially true for files with a high number of reference frames (like this one).

Yep, I also would love to get DXVA1 support in LAV video. I have win7 setup but just can't move all my staff from XP to 7, so often even watch video in XP with working processes in background. Now I have to switch to Cyberlink for heavy video.

Thats even one of those things i wouldn't even accept a patch for, because i simply have no ability to test it and ensure it keeps working (not like i have ever received a patch thats more then 2 lines or so.)

is there a way to select the embedded ac3 track from a dolby true-hd file as default? if so, how would i do that?

sneaker_ger · 26th November 2012, 10:09

Why would you want to do that?
If you want to bitstream and your receiver doesn't do TrueHD just check "Dolby Digital (AC-3)" under bitstreaming in LAV Audio. You could also try to deactivate "TrueHD" in the formats tab.

zeropc · 26th November 2012, 10:15

ac3 and dts are check and dolby thd/dts-hd/eac3 are unchecked, but it wont pass-through the ac3 unless i select it manually. the dts core however gets played without problems.

So the ac3 core and the TrueHD data without any core are in different tracks and LAV Splitter selects the TrueHD track by default?

zeropc · 26th November 2012, 10:36

no... the ac3 core is embedded into the truehd track. the true-hd track, if want to call it that way, is selected as default.

LAV Splitter does actually split the AC3 track out of the TrueHD track, into a separate track, yes. Mostly because those two tracks are completely unrelated, and a TrueHD decoder simply does not need it.
So any TrueHD track output by LAV is pure TrueHD (at least when its from a mpeg-ts file), no AC3 frames in it anymore.

LAV has an option if those "substreams" should be shown as a separate track, or simply discarded.

And no, there is no way to auto-select the AC3 track. Higher Quality Streams are always preferred.

sneaker_ger · 26th November 2012, 11:04

Thx for the explanation. Had to dig out a sample file to actually test it myself because I didn't have any ready. Maybe LAV Splitter could be changed to only select tracks which can be decoded? (So one would have to disable all TrueHD decoders prior and would then select the core instead of the lossless part) Or disable the lossless part in the splitter.
The request itself seems reasonable.

And how would LAV know that?

I have no plans to add options for codec-based selection logic, it would just add a lot of confusion.
