Hardware Transcoding Not Working? Maybe?

So, interesting enough, i remade the MKV Files with just the some random SRT and the Video and Audio. (see below)

Rescanned the Library, and when I played (no subtitles) there was NO GPU transcoding… all CPU, which I don’t understand at all.

When I enabled the Subtitles, with the SRT, it started transcoding with the GPU, no problems. Attached are the logs
