I am on the same situation as @luizkun have installed Kodi following all the steps and can watch some movies, but others won't work (x265 hevc), . Will just get a blank screen with audio and subtitles working fine, but no image. Have you managed to sort this out?
I have followed the guide and verified everything is fine: gbm, drm_prime, direct to plane, etc
@amazingfate@royk please could you assist to resolve this? I am happy to follow any steps to provide additional information you may need or upload some sample videos for you to try to recreate the issue
