LAV Filters - DirectShow Media Splitter and Decoders

[VipZ]

Thanks Mercury for supplying me with test builds

Regarding the lip sync issue, I think it may be fine with the build Nevcairiel-LAVFSplitter-0.22-29-g5ce415f, though its the kind of thing if you look to hard you can possibly think you seeing an issue.

I will update to latest and continue testing.

Will you please try MPC splitter.
I have this issue (mono lpcm in m2ts) using MPC splitter fo ages! Haali works good.

And I do have the same issue using LAV .

[nevcairiel]

Maybe your decoder is broken. The file plays just perfectly for me. I didn't try the MPC Splitter - whats the point, its working for me.
Try using LAV Audio as well, thats what i use for LPCM decoding.

Thank you !

You are right! MPC+LAV audio+LAV splitter work brilliant!

The problem (mono LPCM) is MPC LPCM decoder !?

Have you plans to add bitstreaming (DTS HD MA, Dolby True HD) to LAV audio?

OK I just installed this and tested it with an .mkv that Haali used to report strange fps' on... and..... it works!

My problem - LAV splitter does not load for .AVI files.

Haali has been uninstalled. I've boosted LAV's priority to highest....

MPC-HC reports that some AVI splitter (low merit) gets loaded instead.

Has anyone else encountered this? (Windows 7) Any tips?

[nevcairiel]

AVI is currently broken in 0.22, it'll be fixed in 0.23.

But AVI isn't all that special, using the default splitter in the time being should be fine.

I have problem with default OS AVI splitter and AVIs with multiple audio tracks - graphstudio/player crash when video stop.
Of cousre it is working just fine with LAVF

[nevcairiel]

I was more referring to the MPC-HC splitter, but sure. 0.23 will be out soon enough.

Ahh thanks for the info, I was starting to turn things upside down to figure out what was going on.

I would prefer LAV to load rather than the default Both in MPC-HC and in Mediaportal.

[nevcairiel]

I have one thing to finish to implement, and then some testing and cleaning, then 0.23 should be out. Hopefully i can finish it before the easter weekend.

First, I want to say I'm sorry if I report a known problem again. I don't really watching the thread closely.

I set my mouse wheel to Jump Forward/Backward (medium) in MPC-HC. LAV Spliter almost always get "stuck" when I do forward 2-3 times consecutively. It does not jump forward but jump back to the same point. On somehow related note, there are problems like video and audio getting out of sync after seeked as well. I tested with madVR and EVR Sync. I didn't have this problem last time I tried LAVSpliter. I'm not sure, but I think that was 0.19.

I remember read it somewhere that I supposed to use a special build of ffdshow but cannot find it anymore. Is that still true? Maybe that's the cause?

Hello.Please separate LAVF Splitter from LAVAudio.If posiible could you provide two packages one for LAVF Splitter and one for LAVFAudio.Thank you in advance.

Why?
The splitter and the decoder themself are tiny, the libraries are big, and both use them. So if i create two packages, i would have to double the libraries, thats double the size - i don't see how that is better in any known universe.

[SamuriHL]

No, I'm not in favor of separating them, either.

[Sebastiii]

me too

[RobertinoM]

When I am using Graphstudio and I am rendering a file..

I don't see LAV Splitter? Just for Audio I can see it. But not for Video... Is this correct?

And please keep it in one package, that keeps it simple... (to be honest, I have no idea if it is enough to extract it into one dir e.g. c:\LAV\ and then register the splitter)

Regards Robertino

Sorry, I don't have an answer to your question, but I tested it myself and found it funny that when "jumping" in MPC-HC LAV Splitter would seek to arbitrary frames instead of nearest preceding keyframe, which I asked about recently:

If I seek to the end of a 10 second GOP with Haali, seeking might take a fraction of a second on my quad core. With your splitter I have to watch the entire GOP from start. This also means that you can't seek to chapter starts exactly if they don't start on an I-Frame (for whatever reason).

This can now (I swear I tested it some time ago and it didn't work for some reason, probably stupidity) be done by deactivating MPC-HC's "fast seek(on keyframe)" "tweak".
So I hereby withdraw my feature request, as it can already be done. And it's even better then Haali, because it can be turned on and off.

This isn't really a feature request, just curiosity:

Will LAVSplitter eventually be able to display the forced subs only from PGS subtitle streams? Is that even something a splitter could do, or would that be something for the subtitle renderer?

I think I understand about 70% of what you said, which make me know even less about the details, but disable fast seek like you said works great!

Edit: A/V out of sync after seeked still happen though.
Edit2: Forcing LAV Audio Decoder solved the problem.

All i do is offer the information about those cue points to the player, if it uses them to do faster (yet inaccurate) seeks, its out of my hands.

MPC-HC enabled that option by default some time ago, which already caused some issues, but hey.

Thats something a sub renderer should be doing. I don't interpret any streams, i just send them to the decoders to do their magic with.

Personally, i have only seen BluRays where the forced subs are in their separate track, though. (Sadly, you cannot detect if they are forced subs just from the track. <.<)
