can't play mkv video

[lomero]

i have 2 video mkv 1920x1080 and can't play this video with my preferred player PotPlayer.
VLC play this video without problem. PP not.
why?

and i have find simple string to covert mkv to mp4 with ffmpeg: conversion is superfast but on play with PP the new file mp4 i have same result: can't play...
i use this: ffmpeg -i example.mkv -c copy example.mp4

but not work!

[lomero]

also i have try to convert with no audio (not important for me) with:
ffmpeg -i example.mkv -c copy -an example.mp4
and same result: don't play with PP....

also try to change video render on PP but nothing work...

Potplayer probably doesn't have the video codec you need. Or maybe it's disabled.

Post a pasted text from mediainfo of the problem video.

@ jagabo
PP don't have codec? mmmm.... and disable? i don't have change nothing... where should i look for this thing?

@ johns0

Preferences -> Filter Control -> Video Decoder -> HEVC and H.265 -> Built In Decoder

[lomero]

it is already set by default on Built In Decoder ....
i have latest version of PP 200317 (1.7.21147)

[lomero]

solved.
i have find and installed codec packs of LAV filters (portable version LAVFilters-0.74.1-x64.zip)
from videohelp:

https://www.videohelp.com/software/LAV-Filters

installed this packs, all work correctly with PP.
