Bug #: 4165
Summary: Review Request: nvidia-video-codec-sdk - Hardware
accelerated video encode and decode
Classification: Unclassified
Product: Package Reviews
Version: Current
Platform: All
OS/Version: GNU/Linux
Status: NEW
Severity: normal
Priority: P5
Component: Review Request
AssignedTo: rpmfusion-package-review(a)rpmfusion.org
ReportedBy: leigh123linux(a)gmail.com

SPEC:
https://dl.dropboxusercontent.com/u/6907158/nvenc/nvidia-video-codec-sdk....
SRPM:
https://dl.dropboxusercontent.com/u/6907158/nvenc/nvidia-video-codec-sdk-...
Description:
The Video Codec SDK includes a complete set of high-performance tools,
samples and documentation for hardware accelerated video encode and decode.
I have only included a nvenc-devel sub-package as this will allow the decode
and samples to be packaged as needed.

The License would make this package suitable for the nonfree repo.

Apparently ffmpeg upstream doesn't consider nvEncodeAPI.h to be nonfree since
it doesn't trigger the --enable-nonfree flag in ffmpeg.
But to download the header you need to agree with this particular nvidia
license and be registered to download the sdk. So I wonder if we even are
allowed to redistribute the non-modified source code.
Why are you using nvenc-devel as the produced package name ? Instead of the
plain nvidia-video-codec-sdk ?
At runtime, you will need the xorg-x11-drv-nvidia-cuda package (and the nvidia
card recent enought for the feature).
Can you post a ldd output of your build of libavcodec.so to verify the linked
libraries ?
To be fully enabled, the nvenc feature in ffmpeg would also requires cuda, but
that can be built without it.
I would be more confortable if we could have it enabled in a ffmpeg-nonfree and
eventually a special ffmpeg-cuda

As I see it I'm free to take the nvEncodeAPI.h file from nvidia-video-codec-sdk
and upload it to github as it's MIT and use that as the source instead.
Why are you using nvenc-devel as the produced package name ? Instead
of the
plain nvidia-video-codec-sdk ?
nvidia-video-codec-sdk doesn't describe the package contents, as it only
contains nvEncodeAPI.h nvenc-devel seemed a better name and more descriptive
At runtime, you will need the xorg-x11-drv-nvidia-cuda package (and
the nvidia
card recent enought for the feature).
cuda is optional with nvenc
Can you post a ldd output of your build of libavcodec.so to verify

To be fully enabled, the nvenc feature in ffmpeg would also requires cuda, but
that can be built without it.
even without cuda the speed gains are worth it
I would be more confortable if we could have it enabled in a
ffmpeg-nonfree
Why nonfree
eventually a special ffmpeg-cuda
as for cuda support, do we need it?
perhaps we could do that when/if cuda is ever packaged for rpmfusion.

cuda is optional with nvenc
Sure, it's optional at buildtime and runtime. But
then at runtime nvenc enabled
ffmpeg will dlopen libnvidia-encode.so (the unversionned SO) That libraries is
currently provided by the -cuda subpackage. (despite it's name, libraries
doesn't all relate to cuda indeed)
If the cuda option is enabled in ffmpeg, it will also dlopen libcuda.so
The main purpose of this cuda sub-package was to have all libraries that would
only rely on -cuda + nvidia-kmod (and not main + -libs). So cuda developpers
would only needs -cuda + nvidia-kmod to install the NVIDIA CUDA toolkit. (at
some point, the nvEncodeAPI.h was distributed as part of the toolkit IIRC).
This was specially usefull for optimus enabled laptop using the intel adapter
for display and using the nvidia GPU for CUDA (that will then miss the cuda/gl
interrop, but not as much important).
Now the real concern is to have the ffmpeg binary not to crash if users try to
use ffmpeg nvenc without the required hw or installed libraries.

$ ldd /usr/lib64/libavcodec.so
Okay, so no direct link time dependencies, only
dlopen as expected.
> I would be more confortable if we could have it enabled in a
ffmpeg-nonfree
Why nonfree
That ffmpeg build will be provided in the nonfree section and will be
allowed
to build nonfree dependencies and libraries along with enabling nvenc (and as
such dlopen a nonfree library).

The package name is based on the upstream project and having nvenc named based
on the include directory seems like a good compromise given we only
redistribute a subset of the sdk.
If any copyright holder disagree with our analysis please let us know.
So far the header redistributed is MIT, so this package belong to the free
section.
Package is APPROVED.
