hi,

I hope this is of some use to the developers.

using build 23973-gl from kricker the bluray subtitles work (and look as good as they should!) but they dont seem to have an "end time" so they stay on the screen for a long time.



Here is a log from the ironman bluray where the subtitles stay on too long. I'm playing the .m2ts direct from disc with anydvdhd running. Also verified on a few other blurays (casino royale and life on mars season 1 and 2)

I've also noticed multi line and single line subtitles have different offsets (only in the gl version).
<--gl dx-->

from my laymans view it looks like the gl one is stretching the image vertically to fill 1920*1200 (it looks slighter taller and not 1:1 pixels), instead of staying at the 1920*1080 res. I will try later on my 16:9 AR screen screen. Edit, just tried at 1920*1080, same problem.

[Fred-L]

Same behavior here.
I'm running last svn under Vista...

[neil.j1983]

i was reading somewhere that pgssubs has only recently been added to ffmpeg, so it may be a bug in that rather than xbmc.

[elupus]

Could be in xbmc aswell.. I haven't even tried it since it was added, probably should

[BenInCOSprings]

It was only recently added in FFMPEG.

And whoever put it into XBMC has my appreciation.

[neil.j1983]

thanks for the updates. I too appreciate whoever put it in, the only other player I can think of is mpc-hc, and even then its a bit intermittent.

It wasn't a complaint, and it never is from me (at least I dont mean it as a complaint, even if it sounds like one!).
I just like to know about it, and make sure others are aware.

[elupus]

The ending too late issue could have been solved in svn already actually.

The multiline difference is "solved" in svn aswell.. but not in any really great way. Had to disable to a feature that aligned subtitles to a certain line.

thanks for letting us know. much appreciated.

just got 24102 but now my cd drives are gone (both gl and dx)!, I will wait a few days for a new build and get back to you.

edit: tried 24102 in gl and dx, and the subtitles stay on too long still ,

edit2: the multiline appears to be fixed

[Carlos ze Dwarf]

Here i come with a newbish question: is there anything planned to solve this issue?

I tried to play a bluray m2ts (avatar) for the first time with XBMC (r28256) and the subs just stay on screen until the next dialog, so it's unwatchable...

The only other thread found with forum search on this subject has no answer, so does anyone care about this?
Or is there a solution with remuxing to other containers where pgs are better handled? Or is the problem specific to this build?

Thanks

[edit]: once again, useful info is found after posting... It's all ffmpeg's fault apprently.

[Quasit]

Doesn't MPCHC also rely on ffmpeg (K-Lite pack)? Subs works normally with MPCHC.

[SlaveUnit]

K-lite pack probably uses ffdshow not ffmpeg. Just a guess though since codec packs are a mess most of the time so I stay away.

[elupus]

obviously we want to solve it, but that implies fixing ffmpeg, and learning how to parse the binary code of pgs subs (of which there exist no documentation)

[Quasit]

Ok, so it's ffmpeg that's bugged? Reading this thread it seems they added pgssubs to ffmpeg just last October, which seems strange considering BD was released 2006. Can it really take years to fix a subtitle bug (already gone 6 months)? Sure, I don't know much about programming but if it works with other players it can't be that hard can it?

[BurningSky]

Or is there a solution with remuxing to other containers where pgs are better handled?

You can convert the subtitles to VobSubs (sub/idx) with BDSup2Sub and remux everything to Matroska (mkv).
But the subtitles will be blue, you must edit the idx file and modify the HTML color codes from RGB to BGR.

That is exactly what I was thinking. I think people will start clocking on to this more with Avatar's forced subs [except those who have downloaded rips]
Forced subs are much more irritating with the hang... took me a while to figure out how to get the forced subs yellow, to then find out they hang forever in xbmc... using xbmc-r28256-trunk
