Enabling QuickSync inside Docker

[Olivier_Cazade]

Hello,

We are running Wowza inside a Docker container.

I am trying to enable QuickSync transcoder.

On the host system, I have downloaded and compiled the kernel patches.

I am having this message :

$ sudo dmesg |grep i915
[    9.261783] [drm:intel_modeset_init [i915]] *ERROR* LCPLL1 is disabled
[    9.319317] [drm] Initialized i915 1.6.0 20151010 for 0000:00:02.0 on minor 0
[    9.373637] i915 0000:00:02.0: No connectors reported connected with modes
[    9.486709] i915 0000:00:02.0: fb0: inteldrmfb frame buffer device

Inside the container, I have installed the libs :

RUN tar -xvzf intel-linux-media_generic*.tar.gz && \
    tar -xvJf intel-opencl-16.5*.xz && \
    tar -xvJf intel-opencl-devel-16.5*.xz && \
    cp -dfr etc/* /etc && \
    cp -dfr lib/* /lib && \
    cp -dfr opt/* /opt && \
    cp -dfr usr/* /usr && \
    cp -drf etc/* /etc/

/dev/dri is mounted inside the container

Vainfo seems to work :

      VAProfileNone                   :	<unknown entrypoint>

But, this is what happen when I start a live stream :

./wowzastreamingengine_access.log:2017-01-17	16:00:08	UTC	comment	server	INFO	200	-	JNI:TranscoderSession.isQuickSyncAvailable[_defaultVHost_:dev-live/_definst_/test-qsv]: Intel Quick Sync hardware acceleration is NOT available.	-	-	-	3377.53	-	-	-	-	-	-	-	-	-	-	-	-	-	-	-	-	-	-

What exactly is checking Wowza in order to use QuickSync ?

I don’t understand what is missing.

Any idea ?

Thanks.

Hello Oliver,

This article details the Server specification requirements:

https://www.wowza.com/docs/server-specifications-for-intel-quick-sync-acceleration-with-wowza-transcoder

Since the checks are against the processor you will need to ensure that your Docker container has access to the processor.

• Intel Xeon processors are only supported with the chipsets listed. Intel Xeon configurations with other chipsets are not supported. Previous generations of Intel Core processors are not supported. Intel Celeron and Intel Atom processors are also not supported.

Please let me know if you have found a solution or are still looking for the proper configuration to enable the transcoder offloading via Quick Synch.
