How to get FFmpeg to export the needed symbols on (K)ubuntu cosmic/disco (and similar distros) so OBS and MPV can use NVENC and NVDEC by installing the FFmpeg Nvidia dynamic linker code

nv-codec-headers.git SDK 9.0 #2

Closed Lenglemetz closed 5 years ago

Hi,

I saw the new instructions, so I tried the new build of ffmpeg with "no-sign".

But I had a bug, the build of ffmpeg happens normally, the modules are present but it does not work in OBS

So I looked at the side of videolan codecs is the SDK 9.0 that makes the streaming does not launch in OBS, changing branch (back to 8.2) streaming and recording returns, with a new build of ffmpeg of course.

I think you have to indicate it

regard,

what NVIDIA driver version do you have?

Lenglemetz commented 5 years ago

i have nvidia-driver-415

omen23 commented 5 years ago

wait.. wait .. the nvidia headers work with every version of FFmpeg but the newer headers require a newer driver ...

tbh.. its like dont touch a running system .. when you ffmpeg 4.0.2 running with OBS 22.0.2 and it works dont touch it until you have to – but I will look into it ... also I am having no problem with using -uc -us instead of --no-sign.

FFmpeg version of headers required to interface with Nvidias codec APIs.

Corresponds to Video Codec SDK version 9.0.18.

Minimum required driver versions: Linux: 418.30 or newer Windows: 418.81 or newer

you can get a new version from the nvidia homepage but not as .deb but the blob installer ... which isnt as clean as using your systems packaging system .. give them a few days and they will roll out a new version in the gpu ppa...

need newer drivers - closed

Lenglemetz commented 5 years ago

Hi,

ok, but you forget an instruction .... this command downloads the sdk 9.0 by default, you have to change branch to be in sdk 8.2 :

git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git

omen23 commented 5 years ago

it always should be the newest SDK, when I wrote it SDK 8.2 was the newest .. cant update this manual all the time.

Regards

git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git will get you the SDK 9.0 atleast at the time of writing (18-2-2019) – you see there are multiple projects (all getting updated at different paces – I cant fix this up all the time) – just roll it with SDK 9.0 and download the nvidia binary installer .. if you want to use the new SDK!

Hi,

I just saw the addition of "git checkout n8.2.15.7 # for drivers of 415.x and more", it's cool, you finally understood the initial request ;-)

omen23 commented 5 years ago

Hey, I'd be really thankful if you donated a few euros. Thank you in advance.

"Donations If this manual helped you out in any way and you wanna support me by buying a cup of coffee or a little something donate here." https://github.com/omen23/ffmpeg-ffnvcodec-explanation#donations

Greetings

ps.: why are US people willing to donate and Europeans still think its free as in free beer – if nothing comes back I can't write future "how-to's" and if nothing comes back I won't too – I am not asking for much but idk ... people should be more appreciative a technician coming to your home is easy € 30 just for coming and then € 60 per hr (if not more). This is the only working guide to roll FFmpeg and make libavcodec export h264_nvenc on the internet and make OBS work with NVENC.
