LAV Filters - DirectShow Media Splitter and Decoders

How can I get the lav splitter to prefer the secondary audio stream by default rather than the hearing impaired stream?

Annoyingly the hearing impaired stream is 256kbps compared to the default of 192kbps in my .WTV recordings, so i guess this is why it is being selected by default. In addition to this, playback freezes until I select the correct stream in MPC HC.

Thanks

Anyone? I can't seem to make a flag for it to choose the secondary audio stream.

Heres the view of the splitter during playback:

Rebadging, rebadging and rebadging...

But VP5 for all this time ?

Does it worth to switch for Nvidia with these cards ?

That is what interesting me too. I've got an 9600GT now (with vp2, 64 cuda cores, 256 bit memory interface).

So is it worth to switch to a GT 630 with GDDR5 (96 cuda, 128 bit memory!!!)? Is it inlcludes vp5?
(The other 2 (610,620) are very bad. I know that these are the low end cards now.)

Thanks

There is no way to do that.
Even if the first stream would have the same bitrate as the second stream, it will always prefer the first stream in a file. A rule like "always use the second" just doesn't make much sense.

Its possible that i can add an option to ignore streams marked as hearing impaired in the future, but for now you will have to change it manually.

Can't you just remux the file into MKV and select the second track as the default (or remove the first track altogether and save some disk space)?

The same problem used to exist with UK satellite broadcasts in MediaPortal because the "audio description" stream is first for some reason. Luckily, they are always MP2 and the normal audio is always AC3 so they just added a "prefer AC3" option.

Only Kepler GPUs have VP5, if you buy any of the Fermi rebrands(GT 610/620/630/645), you will NOT get VP5 and other improvements that come with Kepler GPUs. Avoid them and wait for the Kepler GT 640/650 (GK107) retail card.

Use the header editor in mkvmerge gui to change the language tag on the hearing impared track to "und". That will update the file in place and not require a full remux plus allow the track that is still eng to now be preferred by LAV because of your language preferences.

Nevermnid: I see now that you are trying to change a .wtv file. Remux it to another container I guess.

Not quite true - the 520 (now rebranded as the 610) had VP5 before anything else did.

I faced with DVD-playing problem in MPC-HC.
I use LAV decoder preferred in external filters MPC.



When I open single VOB-file from DVD I see LAV decoder is working for me. But when I use "Open DVD" dialog it loads ffdShow decoder but not LAV.



Do you know why?

Can LAV Filters to decode whole DVD? How to setup it?

[Superb]

DVD is not supported yet. Nev started working on it, but supporting subpics properly (needed for the menus) is not easy.

Yah, I figured out after posting that this wasn't the right approach, so I started a thread over on AVS. There's a link below to the thread. Please, please, take a look at my latest reply as it is directed to you and I simply have a couple questions for clarification. Thanks so much for replying as nobody in AVS has had much to say on the matter

On a side note, there was a question burried in the original post regarding the best method of updating LAV Filters without having to lose settings. I would still like that one answered if anyone here is willing. I use the installer method currently, but I think uninstalling and reinstalling will cause me to lose settings. Haven't tried it.

Thanks again so much Andy! I really hope you take a look at the other thread:

Thanks for the clarification ...

Nvidia WHQL 301.42 drivers are out with support of all cards.
Looks like they've fixed black screen with madVR's "use a separate device for presentation" option.

Very kuel! Thanks!

Is that what they are talking about here, or is this a different issue they fixed?

(301.42)When setting a custom resolution on the secondary Dualview (extended mode) display, the display goes blank. [915624]

or maybe this one (from the older 301.24 driver):

(301.24)[GeForce 500 series]: When both an HDTV and PC monitor are connected to the GPU, there is no video on the secondary extended mode display. [939925]

I also noticed this in the changelog:

(301.42)[GeForce 400 series]: There is no picture when using LAV DirectShow Filters on MPCHC for MPEG4 video playback. [952108]

Thanks for the info! I'll install on both desktop and laptop ...

No idea, I've checked with madVR only.

test GTX 460 with 301.42 whql.play mpeg4-asp video with last lav git use cuvid no problem!

[Superb]

Nev, maybe it's time to re-enable CUVID MPEG-4 ASP decoding (in the installer) if the new drivers work properly now...?

Small problem with LAVSplitter which is reporting 5.1 audio and LAVAudio it's saying 7.1

Thats because its DTS-HD, ffmpeg does not support HD (yet), and adding alot of code just to figure out thats its 7.1 instead of 5.1 is just not worth it.

This has also been discussed in great lengths before.
