can not play using Local MP4 file over AVB/TSN on i.MX8MP

[OliverSJ]

I tested and got good working result from follow link:

AVB/TSN demo on i.MX8MP 

And then, I would like to test with local mp4 files

So, I ran below cmd:

gst-launch-1.0 clockselect. \( clock-id=realtime \
    filesrc location=sintel_trailer-480p.mp4 ! qtdemux ! h264parse config-interval=-1 ! \
    avtpcvfpay processing-deadline=20000000 mtu=1400 mtt=2000000 tu=125000 streamid=0xAABBCCDDEEFF000A ! \
    avtpsink ifname=eth1.5 priority=3 processing-deadline=20000000 \)

But, i got error:

0:00:00.087338126 1992 0xaaaaf02a5c40 WARN basesrc gstbasesrc.c:3688:gst_base_src_start_complete:<filesrc0> pad not activated yet

Could you give any advise to fix this issue?

Thanks.

I am trying to run a c++ application on a i.mx8mp with Kirkstone Linux that has configured a Gstreamer pipeline with a avtpsrc -> avtpcvfdepay -> h26parse -> avdec_h264 -> videoconvert -> vvideorate -> vpuenc_hevc -> appsink

The pipline starts running with no problems, but when it starts to receive the AVTP packets over the Base-T1 ethernet port, it begins to complain as follows:

GStreamer-App-CRITICAL **: 16:58:57.771: gst_app_src_end_of_stream: assertion 'GST_IS_APP_SRC (appsrc)' failed

Is there some setting in the avtpsrc plugin that I am missing or is there something wrong with my AVTP stream?

Any suggestions are greatly appreciated.

Hi @brian14 @OliverSJ 

Anyone can guide me related to TSN QDISC setup.

Like if we are not doing this setup what will happen, we will able to run talker/listner application or not.

I am aksing this because i don't have I210 NIC card i have marvel card installed in my intel acrn tiger lake board by which i am able to do timesyncronization. I don't know about the number of queues available in this NIC card and how to configure this.

Thanks.

My setup:Intel tiger lake board (With Marvel NIC)

Do you find any solution for this issue or not? Please guide me if you got any solution.

Thanks.

Hi @OliverSJ, 

Thank you for contacting NXP Support.

Are you working on our EVK or custom board?
What is you BSP version?

It seems that there is a problem related to the clock and it could be an erroneous clock setting.
Please send me the information to check in detail.

Have a great day!
