Works fine with Mediaportal.

TV applications typically have their own source filter and mpegts demuxer, therefor LAV Splitter doesnt really fit into that picture to begin with.

LAV Audio might work with it, depending on the source filter. If the source unpacks the PES data, it will work, if the source directly sends the PES stream without unpacking, it will not.
FWIW, DVBViewer works fine with LAV Audio and LAV CUVID.

Now there is a NIC that broought back a flood of early HTPC memories trying to get those Intel G33 working at 24hz (shudder). I expect to see archibael show up next!

My results: LAV Audio - yes, LAV CUVID - no. On channel change - no picture.

LAV very bad with this sample http://www.multiupload.com/MV7RNMR1LW:
1 - playback don't start, black video in MPC-HC
2 - second video stream detect with error.
3 - detect many "fake" subtitle.

Play fine with MPC-HC internal splitter.

Gleb,
if you wait a few seconds (10-15) the video will come.
Or you can disable "Fast Channel Switching" in Options -> TV + Radio and it will work suddenly but you'll get a black screen in between.
I thought it was only me that had problems with this fast channel switching but I guess it was actually LAV CUVID that is taking too long to adapt/switch ... or potentially clear it's buffers.
Nev,
do you use DVBViewer? Is there anything that can be done to improve it?

P.S. Before you ask yes it's straight from Blu-ray

and "fixed"

Let me answer that for you: It is not, not in *any* way. It does not share *any* code. LAV Splitter is unique, as its the *only* DirectShow splitter that uses ffmpeg for demuxing.

PS:
Your file is fixed.

@Nev and I was just trying to say that the file works (with other splitters)
@Aleksoid Can you fix MPC-HC's MPEG splitter to detect the DTS Express audio too ?

Nevcaireiel, is it possible as a feature to implement in the Lavfilters splitters a method of switching video streams for Bluray - for example my King Kong, Mirrors and Gladiator bluray have more one version - Theatrical, Directors Cut and/or Extended cuts on one BD. When using MPC-HC to play the disk it always defaults to playing the longer version. Can you implement that feature of stream switching or is that something i should be asking the MPC-HC coder(s)

You're right, disabling the option does the job, thanks. However, deinterlacing problems with DVB streams still persist. So usage of LAV CUVID in DVBViewer is limited at the moment.

JaylumX,

I believe the best way to achieve what you want is to find the correct playlist file for the different versions using BDINFO. Then run the appropriate playlist file.

Cheers,

That feature is on Nev's list to implement. No ETA.

The problem is that if someone uses LAV they might not be able to use WMC Live TV.

Do you think that changing the merits will correct this problem?

Nev, I you have planned output bit depth selection for the future, right? If so, could you please consider an option akin to ffdshow's "16-bit LPCM" (not "16-bit integer")? I've just found out that PowerDVD 8's audio decoder can connect to ffdshow's 16-bit LPCM output in order to apply Dolby Headphone, which as far as I can tell is the only way to get DH in a DirectShow player (foobar2000 does it by way of the Cyberlink DH dll).

If it's not too much to ask

I don't think i'll be doing that.

I don't think the subtitles are fake, it detects them properly, and the subtitle PIDs are set properly. Looks just fine.
BTW, the MPC-HC splitter doesn't detect the second video stream at all on the beginning, it just finds it after a few seconds of playback. I think its either broken, or the stream starts really late in the file, i am filtering video streams without a resolution now.
Anyhow, i also increased the size of the probe buffer, which makes it detect the stream.

I do not care about any interaction with a seriously locked down application like WMC. Its a horrible player as it is.

FWIW, eac3to detects a bunch of PGS subtitles, too, so I'd say that LAV Splitter probably is correct about the subtitles.

Wow. Okay then.

What about making it easier for users to control the filter's merit?

The default merit is so high that it will most likely be considered in every graph that isn't explicitly built with direct connections.
