Not WinXP...

I am using the mpc hc 1.7.15 program, I have given the aac file for the rehearsal, and there is such a thing, it's about time:

good, please

It displays a playing time of 28:32:59; which other value would you have expected instead?

And BTW, this is a play time of an MKV, according to the window title, what do you mean with AAC? Did you try to load an external audio file in parallel? Missing details.

this is the time, after loading aac file.

I have no plans to work on that. You should wrap your audio into an actual container if you are about its duration being accurate.

[LigH]

AAC has a variable bitrate. To estimate the playing time accurately, an application would have to collect statistics about the whole audio; a DirectShow decoder will not be able to do that until you have played the whole media already.

It is a pity that there will be no amendment.

how?

It can not render it using FilterGraph.

I do not have an option to register it system wide.

If you have developers who are able to read their C/C++ sources, you will most probably find how they do that directly, bypassing DirectShow automatic graph building.

Thanks, will look at this.

No, Media Foundation is not DirectShow.

Right, i support what i need, looking at this now.
It seems that it is something I need.
Thanks

You can do what you ask with LAV Filters, several other projects load it without registration, and bundling with apps is allowed within what the license allows.

Is there anyway to have advanced splitter mode ignore all subtitles labelled as "Signs"?

Right now I have it set to: "jpn:*|d;jpn:eng;*|f" but many releases flag "signs" as the default subtitle track for anime, and put english subtitles on track 2.

[LigH]

With "signs", they possibly mean "scene subtitles" (translations of readable signs only) in contrast to complete translations of the whole audible speech?

Yes, that's correct. I'd like to ignore them and select the next another english subtitle track if possible.

Not really. I think the "!" operator doesn't work on track names (@nev: feature request?). Maybe you could do e.g.:
jpn:eng|!d jpn:eng
Then it would select the non-default English track first and only if that doesn't exist the first English track regardless of default/forced flagging.

Well at least I can do that while watching shows that do this. Thanks.

I've been trying forever to get my subtitles to work automatically but there's so many releases with flagged "default" english subtitle tracks on english language content throwing me off. I can't get my anime to play well with them.

For example:
*|d;eng:*|f;jpn:eng

I would read this as "First set default track, if english is found enable english forced subs instead, if Japanese is found enable english subs instead. This doesn't work though, english audio content still has default subs selected. Putting *|d at the end instead has the same effect.

So what's the best way to achieve this in one command?
- If japanese audio is found enable english subs, if no english subs enable default subs.
- If english is found enable forced subs.
- If unknown language (or simply not english) enable default subs. <-this seems impossible without overwriting everything else.

Greatly appreciated...
