Hi everyone, i'm newbie on imx. I've some question about gstreamer. I use I.MX8MQ

Main question is Does I.MX8MQ support gstreamer-imx?

When i googled about this, the results mostly be about imx6.

The other question is how to display two or more rtsp sources side-by-side? When i try solution that on below, CPU usage increase about 290% and not showing anything on screen. How to fix this problem?

videomixer name=mix \
sink_0::xpos=0 sink_0::ypos=0 sink_0::alpha=0\
sink_1::xpos=320 sink_1::ypos=0 \
sink_2::xpos=0 sink_2::ypos=200 \
rtspsrc location='rtsp://192.168.1.43/stream0' latency=0 ! rtph264depay ! h264parse ! vpudec ! videoconvert ! videoscale \
! video/x-raw,width=320,height=200 \

Hi Ali

yes i.MX8MQ support gstreamer-imx, for its usage

one can look at sect.7 Multimedia i.MX Linux User’s Guide

For rtsp sect.7.3.12 Real Time Streaming Protocol (RTSP) playback.
