gstreamer-vaapi

[Nick Kallen]

Hi,

I’m trying to get gstreamer-vaapi installed on an Amazon ec2 GPU instance.
When I installed gstreamer on an Ubuntu AMI through apt-get, all gstreamer
decoding and encoding commands gave me an error like 'gstreamer-vaapi
cannot load library’ (I forget the exact error message). vainfo errored
that I didn’t have an x-server running.

I assumed I needed a newer version of gstreamer so I tried to build from
source using cerbero on a redhat AMI. Cerbero built everything successfully
(after I installed yasm by hand). I don’t know how to install the cerbero
generated packages on my system (rpm -i *.rpm seemed to have no effect). If
someone could explain that to me I would appreciate it.

But in any case, I ran 'cerbero shell' and I noticed gstreamer-vaapi was
not automatically installed. I’m having difficulty compiling
gstreamer-vaapi because of missing dependencies and I just have no idea if
I’m on the wrong track to getting this all working together. Can I use
cerbero to compile gstreamer-vaapi? What is the right way to build all of
this together and install it properly on a machine?

Thanks!!

I'm not sure if vaapi has support for addon GPU. It works for Intel's onboard
graphics now. Check if the onboard graphics supports hardware decode/encode

Also, check if vaapi would work on a VM. How would the Intel GMA be shared
across multiple VM on a bare metal hypervisor?

There seem to be many variable :)

The first thing would be to get working vainfo. What kind of GPU does Amazon
provide? VAAPI works well on Intel GPUs and some other GPU using the gallium
drivers.

vainfo should work without an X server running, just it warns about it.

If vainfo doesn't work, which is the most basic libva tool, gstreamer-vaapi
won't work either.

Here is some info about these machines:

I naively thought this would be easy. I am clearly in over my head :(

Back to Ubuntu: After install 'apt install vainfo', it coredumps when I run
it.

(gdb) run

For encoding you should be able to use the 'nvenc' plugin from gst-
plugins-bad on these machines, once you've downloaded and installed the
nvidia sdk.

Hi Tim,

For encoding you should be able to use the 'nvenc' plugin from
gst-plugins-bad on these machines, once you've downloaded and
installed the nvidia sdk.

I’m sorry if this is a dumb question, but even after following the README
instructions here (
https://cgit.freedesktop.org/gstreamer/gst-plugins-bad/tree/sys/nvenc/README )
I can’t find the element nvenc

gst-launch-1.0 rtmpsrc location=rtsp://
wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov ! decodebin !
nvenc

WARNING: erroneous pipeline: no element “nvenc"


But I have gstreamer-plugins-bad installed:


libgstreamer-plugins-bad1.0-0 is already the newest version
(1.8.2-1ubuntu0.2).

libgstreamer-plugins-bad1.0-dev is already the newest version
(1.8.2-1ubuntu0.2).


As far as I can tell, nothing in the sys/ directory of
gstreamer-plugins-bad is available on my ubuntu distribution.


Any suggestions?


Thanks!

Yes, ubuntu doesn't ship the nvenc plugin by default (they can't
because it needs to be compiled against the nvidia headers + libs which
are not FLOSS software).

So you'd have to compile gst-plugins-bad yourself - it's enough to
configure it and then cd sys/nvenc; make; make install in there - no
need for all the other plugins.

Then by default the plugin will be installed into a different prefix,
so you either need to copy it into /usr/lib/../gstreamer-1.0/ manually
or set the GST_PLUGIN_PATH variable to where it was installed, so that
GStreamer finds it.

It's a bit fiddly I'm afraid, but I can assure you it'll work :)

I’m stuck again, sorry :( . I configured with the nvidia libraries:

LDFLAGS="-L/usr/lib/nvidia-367" ./*configure*
--with-cuda-prefix='/usr/local/cuda’


But building nvenc fails when it tries to make the gl module. Here is the
error when I try to make gl directly:

Hi,

I miraculously got it to compile, replacing everywhere it said

# include <GL/gl.h>

with

# include <GL/gl.h>
# include <GL/glext.h>

"sudo make install" put the libraries in /usr/local/lib/gstreamer-1.0

however, simply copying the files libgstnvenc.la libgstnvenc.so into
/usr/lib/x86_64-linux-gnu/gstreamer-1.0/
or /usr/lib/x86_64-linux-gnu doesn’t seem to install the plugin:

however, simply copying the files libgstnvenc.la  libgstnvenc.so

/usr/lib/x86_64-linux-gnu/gstreamer-1.0/ is the right directory, and
you just need to copy the .so file.

Start by running gst-inspect-1.0 on the .so file with the absolute
path, i.e.

gst-inspect-1.0 /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstnvenc.so

and see what it says.

Probably means NvEncodeAPICreateInstance() failed. Might be a case of
driver not being loaded or wrong driver version or something. Or some
incompatibility of the SDK and the distro/version you use. It's all a
bit painful sadly, the joy of proprietary hardware drivers.
