Hi experts,

I try to decode two streams and display them in AM57xx(SW: software-dl.ti.com/.../index_FDS.html) simultaneously on the HDMI

try decode one stream and display and it works

root@am57xx-evm:~# gst-launch-1.0 filesrc location=/usr/share/ti/video/TearOfSteel-Short-1920x800.mov ! qtdemux name=demux demux.video_0 ! queue ! h264parse ! tee name=t ! queue ! ducatih264dec ! queue ! kmssink sync=false t. ! queue ! ducatih264dec ! queue ! fakesink sync=false

I try the following by referring to e2e.ti.com/.../1707053

I try the above but got failure.

According to http://processors.wiki.ti.com/index.php/DRA7xx_GLSDK_7.00.00.04_Release_Notes , there should be demo application on this topic. But I did't find anything under following folder

[er@ cortexa15t2hf-vfp-neon-3.14-oe-linux-gnueabi] (glsdk_dev)$ ls -l /home/aver/ti-glsdk_dra7xx-evm_7_00_00_04/example-applications/

[er@ cortexa15t2hf-vfp-neon-3.14-oe-linux-gnueabi] (glsdk_dev)$

I try to use viddec3test as mentioned in

http://processors.wiki.ti.com/index.php/DRA7xx_GLSDK_Software_Developers_Guide#GLSDK_software_overview , but still have no idea.

Could you help on this??

Thanks

I tried this pipeline using proc SDK 2.0.1 release (will be available on ti.com on 16th of Jan) and the pipeline works fine. Can you try using proc SDK 2.0.1

hi manisha,

Many thanks for your response.

Q1. I didn't find the mentioned release in www.ti.com/.../PROCESSOR-SDK-AM57X

Could you provide the URL ?? because I found someone has download it ( https://e2e.ti.com/support/arm/sitara_arm/f/791/t/482607 )

Q2. In our case, we won't use gstreamer architecture. Could you please provide an example like omadrmtest ??

Thanks.

1. software-dl.ti.com/.../index_FDS.html
2. Only gstreamer architecture is supported by proc SDK.

As I try your provided command in SDK 2.0.1, I got following messages.

You will need to launch the weston to display on wayland sink. You can do so by running weston script on target board as below
#/etc/init.d/weston start

hi manisha,
many thanks for your reply.

We can see the one video overlay another background.

And do you know how to display two video at the same output (PIP, POP) ??

Thanks
