Subtitles have stopped working (MKV)

[adspence]

Sadly this issue is back. I recently installed the latest version of Haali (1.7.401.3) as this fixes a bunch of other playback issues I have. Subs are missing again...and nothing I do will get them back again. Even going back to the exact same versions of CoreAVC, Haali, VSFilter (vobsub) and PVRX2 makes no difference whatsoever.

The really really frustrating thing is that PVRX2 is the ONLY directshow app that can't get the right graph. So there is nothing wrong with the filters at all, its just PVRX2 is ignoring the fact that vobsub should be autoloaded for this file. ARGH!

There is nothing wrong with PVRX2. As I explained, it knows nothing about vobsub, it just askes Directshow to pick an appropriate graph and Directshow takes care of the rest.

I know, I know...but I can't for the life of me make it choose to use the "right" graph (except by saying VS AutoLoad=Y in Haali, which isn't what I want for every file I ever use).

I'm going back to square one and a complete reinstall of XP, and start from scratch. Maybe I'll eventually find the correct masonic handshake that PVRX2 needs to get Vobsub to autoload reliably - or find the app that breaks it (though I have to get it working again first!). Other apps don't seem to have the same problem. They must be asking DS something ever so slightly different. Or Haali or VSfilter or CoreAVC are somehow behaving slightly differently with this one app and nothing else, even though I can't see any settings anywhere that could be different.

I suspect the latter.

Here is the entire source code used for generating the directshow graph when you play a .mkv file in PVRX2.exe, including which filters are used and how they are hooked up:

Code:

[SIZE=2]
hr = pGB->RenderFile(filename, NULL);
[/SIZE]

I'm sure you'll agree there isnt much room to maneuver (or get it wrong) in this tiny bit of code...

Maybe there was something broken with older versions of Haali, but the latest one seems to be fine with PVRX2 when using Autoload option. In the past it loaded the VSfilter for EVERY file that was split with Haali whether it had subtitles or not - which was certainly unecessary and undesirable. Setting it now seems to load it on demand when needed, which is exactly what I want. Looks like other apps manage to trigger the VSfilter loading in DS without this setting being required, why isn't clear (MPC, WMP, GraphEdt all work without needing this option), but no longer matters. Hopefully I can now enjoy my subtitled films without any more pain, and I can hold off on the rebuild. Phew!

Yes indeed, no wiggle room there

Some directshow filters do have special case logic for these very common apps.

Thats interesting. What it does mean is that GraphEdt won't always be a perfect indicator of what PVRX2 is going to do.

What it does mean is that GraphEdt won't always be a perfect indicator of what PVRX2 is going to do.

It is usually a great indicator and shows exactly what you'd get in GB-PVR for a default rendering, but there are some known examples where filters are coded to specific things in known apps, and these ones you mention are usually on the "known list". For example, ffdshow comes with a preconfigured list of applications will automatically be used with and MPC, WMP & GraphEdt are all on that list. You'd have to add PVRX2.exe to that list to get the same behaviour. I dont know whether haali does this, but this is an example of why you'd sometimes see these filters choosing to behave differently in different apps. This is obviously something GB-PVR has no control over though.

Its pretty rare that filters would do this, but some exist.

To dig up an oldish thread, if I'm playing an mkv split through Haali which has a number of subtitle files, is there a keyboard shortcut (and hence a remote control key I can map) which cycles through them? I guess this would need to be a keypress that can control vobsub or can something within GB-PVR control?

Would be great to be able to cycle subs "off", "on when needed", "on", or something like that eg for films which have parts spoken in a foreign language but the majority is english.
