OMX player works good with or without deinterlacer enabled but the memory leaks slowly untill it reaches around few mb then kodi restarts without crashlog. Mermory leaks on OMX player no matter if i have enabled or disabled deinterlacer.

Upload "journalctl --no-pager | paste" after Kodi crashes and doesn't generate a crash log, as this should confirm if the Kodi process is being killed by the OOM killer. Presumably you're monitoring free memory with something like bcmstat.sh, which should be good enough evidence of a memory leak, but journalctl would confirm it for sure (I think).

Also, do the files you are playing have subtitles? There's a known ASS subtitle memory leak (not RPi specific).
