Crash turning on captions on iOS version (worked previously)

1. download MPEG 2 file to VLC

2. start playback

3. try to turn on closed captions (I always use Captions 1)

-> Within a few seconds later, it crashes. (Captions have never shown up.)

(The app says version 2.1, based on 2.1.0-rc1 Riewind)

This did NOT happen on the previous version, I was using captions successfully there

We are using a different subtitles renderer in this release, which supports all international characters but slightly less advanced.

I need a sample file to fix this problem. Please upload a clip to http://streams.videolan.org/upload

Thanks!

Thanks, I will add one soon, hopefully tonight when I get home.

I attached a file via that link. If I try to 'attach file' here, I get no feedback, I didn't even realize it WAS uploading. But wow, the upload speed is slow.

commit 13e35edc Author: Felix Paul Kühne fkuehne@videolan.org Date: Sun Sep 29 14:14:23 2013 +0200

quartztext: add basic font-fallback mechanism instead of crashing (close [#9369](https://code.videolan.org/videolan/vlc/-/issues/9369))

added Status::fixed label

closed

changed milestone to %iOS 2.1.2

I really wish we were able to close our own bugs!

Verified on 2.1.2!

Though now I can't view at e.g. 2x WITH captions.. I get basically a slideshow for video. I'll write up a separate bug for that sometime soon. With the first version for iOS that I used (2.0?), I was able to do 2x with captions, and it played at 2x with the captions shown too.
