LAV Filters - DirectShow Media Splitter and Decoders

[SamuriHL]

Um, woops. At least you're getting them to show up. I can't figure out why the hell they don't show for me.

[nevcairiel]

The positioning problem ruins the idea of using DirectVobSub anyhow, so if ffdshow works for you in applying the subs, well its all good i suppose.

I rather prefer the MPC-HC renderer though, the colors are not all washed out.

Maybe we'll have one day a new filter to replace all of these.

Edit: 1111 posts!

I'd prefer to use DirectVobSub, as well. But, so far, I can't get them to show up at all. DirectVobSub doesn't show up in the loaded DirectShow filters. How is that possible?

[nevcairiel]

All i did in MC16 was configure AVCHD (apparently thats what m2ts falls under) for following:

Source: LAV Splitter Source
Other Filters: LAV Audio, ffdshow video (subs turned off, just for decoding), DirectVobSub
Renderer: madVR

LAV Splitter is currently set to select full subtitles, and the filtering is off.
ffdshow is configured to output both NV12 and YV12.

And it just works.

They have a blu-ray section now. That's where I'm trying to get it to work. I've tried the Cyberlink Video decoder in both software and HAM mode and CoreAVC in software mode. No luck on either.

[nevcairiel]

Same settings for Blu-ray, it just works. Do a graph print out and post it. (context menu during playback -> DirectShow filters -> copy info to clipboard (or so))

I'm using 16.0.76 btw.

[SamuriHL]

I'm using 75. You're right though, it works with ffdshow video decoder. But not, apparently, Cyberlink or CoreAVC??? What the??? And yes, I see the placement issue, as well, when using ffdshow. I even tried to override placement in DirectVobShow settings. Nada.

[nevcairiel]

Works for me with CoreAVC. /me shrugs

But anyhow, its not really usable anyway due to the positioning problem. I don't really feel like hacking too much in the code, its rather ugly. For non-MPC-HC i guess i have to recommend ffdshow.

[SamuriHL]

Oh WEIRD! I put CoreAVC back and it works now?? Man, I give up! Any ideas what's going on with the placement thing?

Ah nevermind on the placement thing then.

I think i know why its screwing up. The forced subs in Avatar are basically one big 1920x1080 frame, so they are fine starting in the top corner. The "normal" subs however are actually smaller and placed somewhere properly - this seems to not work. I can track it down, i think.

Are you talking about PGS?
Things can get even more ugly, as there cannot only be a single small sub, but also several pictures across the screen.

[SamuriHL]

I really wish I knew why I can't get directvobsub to work with the Cyberlink video decoder. I just now fixed HAM mode to get rid of the damn green bar at the bottom of my videos, so, I'm back to being able to use HAM mode again. Now if I could just get DirectVobSub to work I'd be happy.

PS: DirectVobSub worked just fine for PGS for me.
PPS: That build leaks some memory when watching PGS subs .. i already corrected it, but i cba to upload a new build right now. Its nothing extreme, over the whole movie maybe a few megs..

Initial test using D9 - This version works perfectly with FFDSHOW on forced subs! Well dont and thanks. For completness I'll test on other setups/discs and also post my resutls on DirectVobSub Later.

Thanks again for the quick fix!

[SamuriHL]

What video decoder are you using, jmone? DirectVobSub works in MC16 with pretty much any decoder except Cyberlink. (sigh). However, the placement is wrong.

[jmone]

FFDSHOW - with H.264/AVC using ffmpeg-mt

What version of DirectVobSub are you testing with? Is it this one http://sourceforge.net/projects/guli...VobSub%202.39/

[SamuriHL]

No. See earlier in the thread. It's the one from the MPC stand alone filters. vsfilter.dll.

[nevcairiel]

I fixed the positioning bug with DirectVobSub and PGS. I tried for about an hour to fix the underlying problem that caused the bug, but i failed. Stupid DirectVobSub .. so i only fixed PGS instead.

One thing i noticed during testing, DirectVobSub can be _extremely_ slow, especially with alot of subs going on. But i guess thats not to be avoided with software blting the image on the video...

PS:
MPC-HC 3056 for the fix, btw.

[SamuriHL]

Thanks, Nev. I'll build it now and see if it makes any difference. I suspect for now I'm stuck with ffdshow's raw video filter. If I try to add just the subtitle filter it crashes MC16. This is why I badly want a stand alone sub filter.

Here is a build of VSFilter/DirectVobSub r3056, with all the fixes i did today

Quick test = Looks fine to me - worked on Forced Subs and when I turned on Full Subs I did not see any issues with Positioning (using FFDSHOW for the decoder still).
