Hello,

EVM: Ti AM5728 evm

Kernel: 4.4.41

I use this pipeline to simple capture & display and is not working:

gst-launch-1.0 -v --gst-debug=2 v4l2src device=/dev/video1 num-buffers=1000 io-mode=4 ! 'video/x-raw, \
format=(string)YUY2, width=(int)1280, height=(int)720' ! vpe num-input-buffers=8 ! queue ! kmssink

Hello,

Please could you try first to stop Weston and then execute the pipeline. Here is the command:
/etc/init.d/weston stop

Hi,

The pipeline works at the beginning but if I run it one more time it does not work, here is the error:

Hello,

Could you post me what exactly you are running and what you are trying to archive?

Hello,

It was a simple Capture and Display Fullscreen using Ti AM5728 evm camera module and i use this pipeline:

root@am57xx-evm:~# gst-launch-1.0 -v --gst-debug=2 v4l2src device=/dev/video1 num-buffers=900 io-mode=4 ! 'video/x-raw, \
format=(string)YUY2, width=(int)1280, height=(int)720' ! vpe num-input-buffers=8 ! queue ! kmssink

In fact, the pipeline works at the beginning but if I run it one more time it does not work.

Best regards :)

Hello Faiez,

I am sorry I can not understand the use case.

1. First case:
You are running this pipeline

gst-launch-1.0 -v --gst-debug=2 v4l2src device=/dev/video1 num-buffers=900 io-mode=4 ! 'video/x-raw, \
format=(string)YUY2, width=(int)1280, height=(int)720' ! vpe num-input-buffers=8 ! queue ! kmssink

after 900 frames the pipeline receiving EOS and it is moved to Stop State. After that you are running it for second time and then you are observing the error in your post?

or

2. You are running the pipeline and before the execution of the first pipeline is finished you are running it again(simultaneously running two pipelines for capture->kmssink display)? If this is the case, it will not work.

It would be better if you share with me the full console log so I could check what you are executing in the console(the use case)not only the pipeline with the error.

Hello,

1. After the execution of the pipeline it is ended by itself (After 900 frames), after that i'm running it (the same pipeline) for second time and then i'm observing the error in my post (and it was always like that),

2. The use case it was a simple Capture and Display Fullscreen using Ti AM5728 evm camera module.

Best regards :)

Hello,

Please share the full console log.

Could you try when the first pipeline ends to run not the gstreamer pipeline run this instead of gstreamer:
yavta -c60 -fYUYV -Fvout_1280x720_yuyv.yuv -s1280x720 /dev/video1
Here is the wiki how you could run this example:
processors.wiki.ti.com/.../Linux_Core_VIP_User's_Guide

Could you execute this command after the first pipeline ends :
ls /dev/video*

Could you add -e to the pipeline also:
gst-launch-1.0 -v --gst-debug=2 -e v4l2src device=/dev/video1 num-buffers=900 io-mode=4 ! ....

Hello,

Also i need to know the default frame rate of the camera module.
