TMS320DM8168: WARNING: erroneous pipeline: no element "h264parse" on gstreamer-0.10

Ehsan Hemati

Intellectual 785 points

Part Number: TMS320DM8168

Hi Everyone

I am Using EZSDK 5_5_02_00 , When I running gst-lunch as the EZSDK_Software_Guide Reference,I have this Warning On my terminal ?

what should I do ?

At first I run these Command to Turn off graphic planes :

echo 0 > /sys/devices/platform/vpss/graphics0/enabled

echo 0 > /sys/devices/platform/vpss/graphics1/enabled

echo 0 > /sys/devices/platform/vpss/graphics2/enabled

Are these Command needs ? why we are do this ?

then I run gstreamer pipline with this Command and have Warning h264parse:

My Command is :

gst-launch -v filesrc location=/usr/share/ti/data/videos/dm816x_1080p_demo.264 \
! 'video/x-h264' ! h264parse access-unit=true ! omx_h264dec ! omx_scaler \
! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 ! omx_videosink sync=false

Hello,

Please restart the board and try:
root@dm816x-evm:~# /etc/init.d/matrix-gui-e stop
Stopping Matrix GUI application.
root@dm816x-evm:~# /etc/init.d/pvr-init stop
Stopping PVR

This command will stop the matrix GUI.

Execute the pipeline.
If you still observing the error please execute:
gst-inspect | grep "parse"
and post the result of this command.
H264parse is part of the bad plugin which is included in EZSDK. You could try to create a new SD card with EZSDK also.
Please post the execution of the pipeline in the console also.

Could you create a new SD card?

It seems like the bad plugin is missing.

In ezsdk there is a bad plugin so may be something gets wrong when the sd card was created.

No . didnt't create new SD card . do you think we need do it again ? and create new sd card ?
when I run video demo from Connect one end of the supplied component video cable to the component video connector (J5,
J6, and J7) everything is ok and show the video on LCD .
why we have error when run command and execute pipline ?
if bad plugin missing , why video show on LCD with Connectors ?

Hello,

What is the pipeline that you are running for capture.
My point is that when you create a sd card the parsers lib could be corrupted and this could be the reason why you do not see parsers.
Please try to create a new sd card.

gst-launch -v filesrc location=/usr/share/ti/data/videos/dm816x_1080p_demo.264 \
! 'video/x-h264' ! h264parse access-unit=true ! omx_h264dec ! omx_scaler \
! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 ! omx_videosink sync=false

why we have H264parse Error ?
If plugin missing why show on LCD ?

Hello,

Could you post the console prints when you are executing the pipeline?

gst-launch -v filesrc location=/usr/share/ti/data/videos/dm816x_1080p_demo.264 \

Hello,

Is this the case when you are seeing video on display?
I do not see the pipeline to move in playing state at all.

Please create a new sd card or check is the .so file exist in your rootfs.

Hello,

What is the use case when this is working?
The pipeline is correct.
This pipeline was tested and it was working.
What is EZSDK version that you are using?
Are you using EVM?
Did you tried to create a new SD card?

Could you try with another video file?

Hello,

The application demos which could be run by selecting the "Multimedia" icon at the top-level matrix are shell scripts( *.sh), they are running gstreamer pipelines. You could search it in your rootfs /usr/bin.

I am not sure why you do not have h264parse element.

Ehsan Hemati said:

You could give a try and let me know the result.

Ehsan Hemati said:

I have used many times pipelines which contains h264parse on dm8168 without a problem with EZSDK.

Hello Margarita Gashova ,

I Have libgsth264parse.so file .
this means I have h264parse element in my target ?
is it right ?

0 Margarita Gashova over 6 years ago in reply to Ehsan Hemati

TI__Guru* 80190 points

Hello,

But since you do not see the h264parse when you are using gst-inspect "h264parse" command something is wrong.
Could you try command like gst-inspect "mpeg4videoparse" also ?

0 Ehsan Hemati over 6 years ago in reply to Margarita Gashova

Hello Margarita Gashova

I try this Command and is as the same as "h264parse" .

root@dm816x-evm:~#  gst-inspect "mpeg4videoparse"                              

No such element or plugin 'mpeg4videoparse'

Hello,

It seems like the bad plugin is missing.
Please create a new sd card.

Or you could try gst-inspect-0.10 /path/to/lib
In this case if you are observing that is in blacklist you could try remove the old plugin cache:

rm -rf /path to the cache registry/

export GST_PLUGIN_PATH=/usr/.../lib/gstreamer-0.10
gst-inspect
this shall rebuild the cache.

Path to the parser lib.

Ehsan Hemati said:

You could try the above command in case the result of the gst-inspect /path to the lib/ you see it in blacklist.

If I remember right the gst registry cache should be under /home/root/.cache/

Hello,

I am not sure what is wrong in your rootfs.
On my side there are parser elements.
Please create a new sd card with EZSDK.
