[gst-devel] videomixer issue

[palani at i-rode.com]

Hi,

I tried the following command.

gst-launch -v filesrc location=/home/test.mp4 mfw_mp4demuxer !
mfw_vpudecoder ! videobox ! videomixer ! videobox ! mfw_v4lsink

I get the following errors.

Can someone help me in fixing the above errors? The pipeline works well
without videomixer.
