HW HEVC Issue v0.1.0 (Alpha 1) about moonlight-qt HOT 1 CLOSED

Ok, so there's a few layers to this issue.

First, your GPU doesn't have full HEVC decoding in hardware (it was added later in 900 series lower end GPUs). Your GPU is Feature Set E, which didn't have dedicated HEVC decoding hardware yet. There's a list of the GPUs and what they support decoding here - https://en.wikipedia.org/wiki/Nvidia_PureVideo#Table_of_GPUs_containing_a_PureVideo_SIP_block

Since Pre-Alpha 5, HEVC has been blacklisted on your GPU to avoid poor performance by the hybrid decoder, so Moonlight will fall back to H.264 to get the best performing stream. However, prior to this release, there was no warning that Moonlight was doing this, so you'd select HEVC (even forced on) and Moonlight would silently use H.264 if HEVC was blacklisted for your GPU.

In Alpha 1, Moonlight respects your HEVC force setting and requests HEVC with the software decoder. However, in your configuration you've forced hardware decoding too. Since your configuration prevents Moonlight from falling back to H.264 to use hardware decoding (what it would do on all Auto settings) or falling back to software decoding to give you HEVC (what it would do on Force HEVC with Auto decoder), it can't meet both of your requirements together due to the HEVC blacklist preventing your GPU from being used. As a result, it fails to initialize the decoder and returns to the app list.

There are clearly some issues here though:

• You should get a dialog explaining what happened if the decoder fails to initialize
• You should not see the software decoding warning if you've explicitly forced HW
