Transcoding options

[sftech13 25]

I was updating my FFMPEG today and now I dont see my video card or decoder options anymore. How do I get them back?

Hi, wise exactly did you do?

[sftech13 25]

updated FFMPEG to current and ensured NVENC was working. It wasnt working for transcoding before. 

I used a custom built FFMPEG

Custom built with Emby?

[sftech13 25]

No but still use the emby path for FFMPEG

Are you able to revert what you did?

[sftech13 25]

I dont think so. 

I tried to roll back to the version I found in a old log. Didnt seem to fix it.
