I installed it. Is there a way to see that hw acceleration exists? I think there was console program for such info.You can try LibreELEC 9.2 with Kodi 18.9 which AFAIK has hw acceleration for videos. Newer versions of LibreELEC like 10, 11 doesn't use hw acceleration for older PIs.
Please check wiki of LibreELEC: wikiI installed it. Is there a way to see that hw acceleration exists? I think there was console program for such info.
