I420 to BGRA unaccelerated/unoptimized on ARM?

[Peter Maersk-Moller]

Hi.

I'm running GStreamer 1.5 Git Master on ODroid-U2 (4 core ARMv7 with Neon).
It should be ORC enabled as far as I know.

When I try to use videoconvert for converting I420 to BGRA I see an
excessive CPU load. Is that to be expected? Can we expect any significant
improvement in a near future?

This is the baseline pipeline I run to see the load:

gst-launch-1.0 videotestsrc is-live=true !
'video/x-raw,width=1280,height=720,format=I420' ! queue ! videoconvert !
fakesink sync=true

I see a CPU load of approx. 45%. A bit higher than expected though.

This is the pipeline with the I420 to BGRA conversion

gst-launch-1.0 videotestsrc is-live=true !
'video/x-raw,width=1280,height=720,format=I420' ! queue ! videoconvert !
'video/x-raw,format=BGRA' ! fakesink sync=true.

I now see a CPU load of 141% and even suspect it may not run at framerate
though I can be wrong.

Best regards
Peter MM
