Bug #3922
nvenc not working
0%
Description
I compiled using latets git "gb536cdb", and when i try to transcode with nvenc_h264 i get following error:
@2016-08-07 12:38:14.097 libav: This encoder is deprecated, use 'h264_nvenc' instead
2016-08-07 12:38:14.098 libav: Failed to create nvenc instance: invalid version (15)
2016-08-07 12:38:14.098 transcode: 0004: Unable to open nvenc_h264 encoder@
As far as I can tell there was a change in the official branch, regarding this on June 25?
[[https://github.com/FFmpeg/FFmpeg/search?utf8=%E2%9C%93&q=This+encoder+is+deprecated%2C+use+%27h264_nvenc%27+instead]]
Hope someone can guide me further, on how to resolve this.
Best regards
Chris

It's working now.
I was missing Cuda and nvidia-367. Installed as referred to here in these sources.

Still get the "libav: This encoder is deprecated, use 'h264_nvenc' instead", but happy I got picture now.

Hello Chris,
how many streams can your graphics card transcode?

I only have two tuners, and these can be transcoded simultaneously.
I'm running on a Zotac Magnus EN970 with a Geforce GTX 960 and a dual core i5, ssd and 16 gigs of ram.
Thanks for showing interest.
Kind regards

Sadly, that's all you will ever get. The drivers artificially limit the number of concurrent hardware encodes to 2.
