crash caused by subtitles

[techywarrior 688]

I'm getting an app crash with some videos that have subtitles. The same files play fine in VLC. In this case the file is MKV with h.264 video, mp4a audio, and ssa subtitle.

I'm not sure why the app is reporting that the start time is invalid since it works in VLC. And even if it is, shouldn't that be caught and not crash the app?

It's an issue with the player framework and the error can't be caught.

BUT I know what the problem is and will build my own version from source. It will be fixed in next version.

Cool.

 

Will that fix some of the other player issues? I also sometimes see that there is a slight stutter in playback (less then half a second) that doesn't happen if I play in VLC or the MS Video app.
