Hi team,

We are using linaro18.01 release. we want to know vp8enc/dec support hardware acceleration or not. how we can validate it’s hardware acceleration or software?

Thanks,

Dragonboard410c supports VP8 hardware decoding via v4l2 interface (gst-inspect-1.0 v4l2vp8dec for more information).

You can get supported hw decodable formats with:

v4l2-ctl --list-formats -d /dev/v4l/by-path/platform-1d00000.video-codec-video-index
ioctl: VIDIOC_ENUM_FMT
Type: Video Capture Multiplanar

[0]: 'MPG4' (MPEG-4 part 2 ES, compressed)
[1]: 'H263' (H.263, compressed)
[2]: 'H264' (H.264, compressed)
[3]: 'VP80' (VP8, compressed)

Here is an example of VP8 hardware decoded gstreamer pipeline:

export DISPLAY=:0 
gst-launch-1.0 filesrc location=Volcano_Lava_Sample.webm ! matroskademux !  v4l2vp8dec ! autovideosink

And below an example without using hardware encoder:

gst-launch-1.0 filesrc location=Volcano_Lava_Sample.webm ! matroskademux !  vp8dec ! autovideosink

You will clearly see a difference.

18.01 is no longer supported, I suggest you to move on latest release (19.01):
https://releases.linaro.org/96boards/dragonboard410c/linaro/debian/latest/

This is the one I used for testing vp8 decoding.
