Wrong subtitle timing

[otommod]

So I was watching this movie yesterday and I had this weird timing problem.
It was displaying the subs of around 01:00:00,000 at the start of the movie and it continued from there.
I tried it on mplayer2 and it played them alright though.
Subs were on an external .str file.

It's a known issue, but we couldn't tracked down it yet.

Did you compile mpv with gcc 4.8 by any chance?

[otommod]

Yes I did.

Yep, compilation somehow breaks with gcc 4.8. Could be either a bug in the mpv code (ignores hours for some reason), or a gcc compiler bug. We haven't touched this part of the code for quite a while, though.

[otommod]

You are right, it is GCC's problem. I just compiled with Clang 3.2 and subs work fine.

As expected, it was a problem with undefined behavior, and gcc-4.8's optimizer is probably more aggressive than earlier versions, which caused the issue. Commit d98e61e should fix this. Can someone confirm?

[otommod]

I can confirm that this is fixed. Thank you very much!

Thanks for testing.
