The only codec supported by the ArcSoft TotalMedia CODECs Pack appears to be H264. There was nothing related to H265 compatibility. But TotalMedia can be enhanced with other codecs as well, so if this is not compatible with H265, then simply install Combined Community Codec Pack that is very effective when it comes to file playback and support.
Reach the application's page at Software Informer to download a version of the pack. Install it and then test compatibility with H265 codec.
