Linux: AM57XX gst-play

Hi,
I tried all the combinations from
processors.wiki.ti.com/.../Processor_Training:_Multimedia
and still complains about gtbdadm user source file . Even creating a window in wayland desktop fails.

Hi,

I havd more success with media without sound, up to 5 seconds but we get

Trying to dispose element vpe, but it is in READY instead of the NULL state.
You need to explicitly set elements to the NULL state before
dropping the final reference, to allow them to clean up.
This problem may also be caused by a refcounting bug in the
application or some element.

Hi,
After more tests all we can play is one single file from this site:
www.engr.colostate.edu/.../drop.avi
Anything else, any other avi, mp* files yields all kind of errors.


Is anyone testing these boards and SDK releases or just trows them
out there in the hope the minuscule community is resolving them?!?!

Hello,

ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Cannot identify device '/dev/video1'.

The pipeline that you are trying is for capture display. The error that you are seeing indicates that the camera module is probably not connected.

root@am57xx-evm:~# which playbin

If you want to check the some element is present in the plugins and the element description you could use :

1. gst-inspect-1.0 "playbin"

or if you are not sure in the element's name use:

2. gst-inspect-1.0 | grep "dec"

this will display all elements which contains "dec" in the name.

As I said I would recommend you to try with playbin for decode display:

gst-launch-1.0 playbin uri=file:///<path_to_file> video-sink=kmssink audio-sink=alsasink

In case of kmssink usage the  /etc/init.d/weston should be stop.

Under /usr/share/ti/videos you could find example videos.

I would recommend you also to add gst-debug=3 -v in the pipeline for more debug prints.

Hi.
Thank you for the prompt and fast answer. I might be needing to give more information.

HW: Board we are running is: REV1.2A, AM572X Industrial EVM

weston stopped.
kmscube runs OK
playin video yelds erros, and the display goes dark for a second

Hello,

It seems like the error comes form kmssink, it can not calculate the aspect ratio of this video.
Could you try to scale it?
Did you tried to play videos under /usr/share/ti/videos?

Hi Margarita,

The SDK I mentioned I installed has no folder /usr/share/ti/videos
