Linux/AM3358: Matrix/Multimedia is not working properly

1. When weston is stop.

 /etc/init.d/weston stop

gst-launch-1.0 playbin uri=file:///<path to the file and filename> video-sink="videoconvert ! videoscale ! autovideosink"

Video does not play properly after executing these two instructions. Just show Please wait...

The log is as follows：

# gst-launch-1.0 playbin uri=file:///usr/share/ti/video/TearOfSteel-AV-Short-400x240.mp4 video-sink="videoconvert ! videoscale ! autovideosink"

Hello, 

No. 

kmscube is not gstreamer element it is a graphic demo.

Hi Margarita:

Hello,

Okay so it is running. 

The gst kmssink's element is not a TI element. It is part of gstreamer-bad plugin. 

I would recommend you to try pipeline like:

gst-launch-1.0 playbin uri=file:///usr/share/ti/video/TearOfSteel-AV-Short-720x420.mp4 video-sink="videoconvert ! videoscale ! kmssink force-modesetting=true connector-id=35" 

where connector ID value must be change. You could check connector ID by running:

modetest

Hope this helps. You could use pipeline with waylandsink.

Margarita

If use waylandsink, must turn on Weston

The display screen is as follows：

Hello,

No. When you run it with weston you must set capsfilter like this:

gst-launch-1.0 playbin uri=file:///usr/share/ti/video/<path to the file and filename> video-sink=" videoconvert ! 'video/x-raw,format=(string)NV12, width=720,height=420' ! videoscale !  'video/x-raw,format=(string)NV12, width=420,height=240' ! waylandsink"

But it's normal on EVMSK.

This command is normal on our board.
