[FFmpeg-devel] [PATCH] avcodec/nvenc: Video Codec SDK 10 features support

[Roman Arzumanyan]

Hello, nice to meet you.

>Wouldn't it make sense to transition from compile time version checks to runtime checking?
Video Codec SDK headers are not included into ffmpeg 'as is' but using the nvcodec-headers project instead.
This is community-driven project which aims to work around the licensing policies.
So we can't influence ffmpeg development too much and only supports it's development with patches.
Changing compile-time checks with runtime checks is a big thing to do and in order to convince community to accept such changes we need to have very solid background.

Hi Roman, Yogender,

great to see somebody from Nvidia here. I think it's been a while.. :-)

I have a rather general question: Wouldn't it make sense to transition
from compile time version checks to runtime checking?
(like Intel does..)

We're currently stuck at SDK 8.1 because otherwise it would break
functionality for customers having devices for which no newer drivers
are available.
