NVEncC 4.52 and DGIndexNV 2053.0.0.189 both work fine, but since the NVEncC 4.51 stated 'Update to NVENC SDK 9.1, now NVIDIA graphics driver 436.15 or later is required' I wonder if this is a driver vs. API issue. -> Anyone else experiencing this? Or is this just my machine? Any idea how to fix this? I tried the latest build from zeranoe (20191013-4f4334b) and a build I compiled on my machine using MBAS. I deinstalled and reinstalled the NVIDIA drivers. Cu Selur |

I didn't look too closely but it probably has to do with the syntax change regarding -refs 3
see this https://trac.ffmpeg.org/ticket/8254 |

Good catch! removing '-refs 3' from the call and the error doesn't happen.
Reading the ticket, really seems like the main issue is that: a. ffmpeg has no option to check what features are supported by the used card b. the error message is really misleading Thanks! Cu Selur |

The real problem is that the actual message to explain why it fails is not shown on a default log level, that should probably be changed so that users know why its not working.

"No NVENC capable devices found" and a device not capable of supporting a specific options for me are two totally different things.
Something similar to NVEnCs '--check-features' would really be helpful with ffmpegs NVEnc support. Identifying that feature X is not supported by having to run into an error is less than optimal from my point of view. Cu Selur |
