Streaming FEZ with Intel Quick Sync to Mac disconnects stream

[MichaelMKenny]

ISSUE:

Streaming FEZ using Intel Quick Sync encoding to an OS X Client using VideoToolbox decoding will disconnect the stream around 1/3 of the time.

It won't disconnect abruptly every time. If it doesn't disconnect on the first try of reproducing this, just quit the game via in-game menus and try again. I've had it work 3 times in a row before it disconnected on the fourth time (but that was very rare). Usually it will disconnect on the second time.

On rare occasions I've had it kernal panic my Mac.


POINTS:

- Using NVENC, NVFBC, software encoding works. It's only Quick Sync.
- Streaming to a Windows client using it's variation of hardware decoding also works.
- Steam Link works.
- Using software decoding on my Mac will work. But I'd rather not, because battery life.
- I've tried other games such as The Witness, which doesn't seem to have this issue but other games such as Batman Arkham Knight do though. But it most easily reproducable with FEZ.
- I also successfully tried using "-dumpvideostream" to capture a stream that might crash OS X, but didn't. I was hoping to be able to radar it to Apple :(


OTHER:

I've reported variations of this issue over the life of In-Home Streaming but has never been fully fixed, it's sort of been an off and on sort of bug.

If a Steam dev is reading it would mean allot to me if you replied, even if a fix isn't immediately clear.

I know it's a bit on the lengthy side, but I didn't want to leave anything out so you can squash this bug once and for all.


NOT SURE:

Where's the best place to post someting like this for best dev visibility? I'm not sure anyone reads the In-Home Streaming discussions anymore, it feels like the Steam Link discussions are the place to be. Correct me if I'm wrong.
