Hello

When playing a video whith ass subtitles, kodi memory usage goes up until the system crash.
Only happen with ass subtitles, exact same subtitles in subrip ( srt ) format play without any problem.

my Setup

Raspberry Pi 1 Model B
ArchLinux ARM
15.0-ALPHA1 Git:2015-02-11-d914021-dirty Media Center Kodi

Can you produce a small sample, which when played on loop causes an out of memory crash?

GloW · 2015-02-24, 23:41

I could, but the bug is produced with actually any movies playing with this subtitles for example:
sub

**popcornmix** · 2015-02-24, 23:59

Can you confirm if a short (e.g. 30 second) video file named the same as that .ass file, and set to play on repeat will crash kodi with an out-of-memory error?

Confirmed with this video : http://www.filedropper.com/output_6
and this subtitle : http://www.filedropper.com/output_7

before playing:

Code:
[pi@alarmpi ~]$ free -m

              total        used        free      shared  buff/cache   available

Mem:            369          65           3           0         300         290

Swap:             0           0           0

Starting to play :

Code:
[pi@alarmpi ~]$ free -m

              total        used        free      shared  buff/cache   available

Mem:            369          91           6           0         271         263

Swap:             0           0           0

After ~15 minutes of playback :

Code:
[pi@alarmpi ~]$ free -m

              total        used        free      shared  buff/cache   available

Mem:            369         215           4           0         149         139

Swap:             0           0           0

After ~30 minutes of playback :

Code:
[pi@alarmpi ~]$ free -m

              total        used        free      shared  buff/cache   available

Mem:            369         318           4           0          46          36

Swap:             0           0           0

Then kodi crashes shortly after and restarted.

I dropped an MKV alongside the .ass from post#3, played the MKV (looks like Korean, Chinese or Japanese subs?) and according to bcmstat the Pi2 with latest #0224 build is leaking about 1-2MB every 10 seconds.

However it's a similar story on x86, so doesn't seem to be a Pi-specific issue.

Maybe this thread needs to be moved to the General section. Certainly needs a Trac ticket.

GloW · (This post was last modified: 2015-02-25, 13:04 by GloW.)

Indeed, it is chinese/english sub, but the problem can be reproduced with standard english ass subtitles :
http://www.filedropper.com/homelands01e0...vid-asapen

The leak is not as fast though, probably because there is half less subtitle displayed.

Here come the trac ticket :

No, that's 4 years old and marked as fixed. I think this needs a new trac ticket.

already done, see previous post.
It was just a reference so the dev may have a possible starting point.

85MB leaked in 11 minutes (~132KB/second).

note that MemFree is not available memory for applications on Linux. The OS may use memory for other things and gives it to applications if requested.

This would explain why watching more than a 20 minute episode with the English (CC) subtitles on leads to a crash for me. I was wondering about that. I had chalked it up to Pi being underpowered.

Hi, sorry to bump this old thread, but does anyone know if these has been fixed in Isengard, specifically for the raspberry?
Where can I find if there´s been any changes?
Will try to test myself but I'm running mysql so don't wanna change that.
Thanks.

Edit: Nevermind, found it, sorry, new to this.
