Converting to a lower quality fails with Hardware-Accelerated Streaming in Plex Web

[jpurpura]

I have seen a couple other threads here and there about this issue:

Hardware transcoding only failing in browser and PMP

Many thanks for your help! (and sorry for my late reply) Well, I tried nearly everything again… reinstalling plex, the Nvidia driver … no luck. But I think I found the culprit. The Quadro M2000 is only sitting in a tiny x4 slot and I think that’s why nearly everything fails. Could be luck transcoding works with the mobile app, who knows… I´ll try it in a different system with a proper x16 slot and let you know!

This guy says his was fixed, but no luck for me. I’ve attached some debug logs from mine, at 15:42:11 I chose a lower quality from a file playing in original quality and it just froze with a black screen.
