<p>There is no such device in the mainline kernel. This is part of
the non-mainline VPU driver from the imx-kerne.</p>
<p>Are you trying to use gstreamer-imx' imxvpudec? With the mainline
kernel, you have to use v4l2Nvideodec instead (where N is some
number ... just do gst-inspect-1.0 | grep v4l to find it).</p>

<div>I'm trying to use gst 1.0 in imx_6q platform based board
and encountered with the /dev/mxc_vpu error when I use
kmssink.</div>
<div><br>
</div>
<div>please find the detailed steps[1]</div>
<div><br>
</div>
<div>I have inserted CODA module and it got successfully
inserted. From the logs of this CODA module insertion i found
that codec registered as /dev/video[8-9].</div>
<div><br>
</div>
<div>Coda version i'm using is </div>
<div>
<div> coda 2040000.vpu: Firmware code revision: 46072</div>
<div> coda 2040000.vpu: Initialized CODA960.</div>
</div>
<div><br>
</div>
<div>But when called gst-launch-1.0 with the args below, i ended
with error</div>
<div><br>
</div>
<div>[ERR] Can't open /dev/mxc_vpu: No such file or directory</div>
<div>[ERR] IOSystemInit() failure.</div>
<div><br>
</div>
<div>May i know will the coda module will create the mxc_vpu
driver ? which part of code will create this driver for
gstreamer to run ? <br>
<br>
</div>
<div>Also im seeing white rectangular screen overlapped on the
left side of the video and video playback is very slow.</div>
<div><br>
</div>
