I was going to give you feedback but I noticed that I can no longer log into my (forums) account. It just says

> **No login methods**

> No login methods are configured.  
> Administrators can visit /u/admin-login to reconfigure the site.

and afterwards

> **The change you wanted was rejected.**

I googled the error message and the only other [mention](https://www.reddit.com/r/PleX/comments/1jtygxk/changing_my_email_address_locked_me_out_of_the/) of this issue says that it happend to them after changing their email address. I think that that’s also happening here? I’ve changed my email many months ago but maybe I didn’t log into my account for that long. If a mod wants to help me with this please PM me and I’ll tell you my info.

With that out of the way I got the new Transcoder and haven’t found any functional regressions. I did some performance tests though and the old Transcoder is considerably faster:

| | Scale | Scale + Burn-in |
| --- | --- | --- |
| 1.42.1.10060 | 4.04x | 3.64x |
| Preview | 2.66x | 2.23x |

Meaning with this new Transcoder I can only serve up to 2 clients at once whereas in the past I could do 3-4.

Interestingly enough these are `h264_vaapi` numbers but `hevc_vaapi` hasn’t resulted in a significant performance pentalty. Which is weird because if I do the transcoding with `ffmpeg` directly I get way higher performance with H.264:

| | Scale |
| --- | --- |
| `hevc_vaapi` | 4.09x |
| `h264_vaapi` | 11.4x |

_(Note that this is not an apples to apples comparsion. It’s just to demonstrate the performance difference between codecs)_
