catch-up offset causing kodi crash

[heidaren0000]

Hi dear devs, I've been using your plugin streaming TV shows for serval months, it's really a fantanstic piece of software, simple but powerful.

Recently i'm trying to add catch up function to my tv sources, the servers are dumped from an ISP TV box, it use offset to time shift and catch up. The URLs are like this:

http://39.136.108.181:6610/shandong_cabletv.tstv.zte.com/223.99.253.7:8081/00/SNM/CHANNEL00000345/1000.m3u8?offsettime=0&zte_bandwidth=1000&m3u8_level=2

Core parameters are:

• offsettime={offset:1}: shift time seconds from current time. the smallest gap available from server is 10s.
• CHANNEL00000345: TV id. i hardcoded them in m3u8.

So my sources are like this:

#EXTINF:0 catchup="default" catchup-source="http://39.136.108.181:6610/shandong_cabletv.tstv.zte.com/223.99.253.7:8081/00/SNM/CHANNEL00000313/1000.m3u8?offsettime=120&zte_bandwidth=1000&m3u8_level=2",齐鲁高清

however, everytime i trying to drag the play progress bar, Kodi App would crash immediately without any error message. I've tested on both android and macOS

details of the core dump are in this file:

the m3u8 i made:(servers are only available for my ISP)

dest.txt

I'm on latest kodi(Kodi v21.2 (Omega)) and iptvsimple plugin(21.10.1).

Hope you could help me fix this issue.
Thank you!
