Reading an RTSP stream from a Sony camera using GStreamer on TX2

Autonomous Machines Jetson & Embedded Systems Jetson TX2
1

We freshly installed Jetpack 4.2.0 Jetson TX2 (P2597) (4.2.2 did not boot after flushing it).

Our TX2 is connected via LAN cable to a HP 2530-8G PoE+ Switch that has connected to it 7 Sony SNC-EB600 cameras.

When I try to run GStreamer this is what I get:

The same command on our PC (with NVIDIA graphic card) shows the camera stream successfully.

Showing the camera output using mplayer works fine (shows the camera stream on screen) though there are some errors outputed to the console:

We are porting an application from Ubuntu on PC to our TX2 and our application use GStreamer internally.

Any help would be apprciated

Hi,
It looks like the pipeline is not complete. Please refer to following posts to construct a pipeline from source to sink:

Hi DaneLLL,

The same command line works on a regular PC. If the pipeline is not complete with this command line then the default behavior is broken. Please fix it.

Thank you, Sela.

@sela_lerer,

You should double check what you’re saying. As said by @DaneLLL, the gstreamer pipeline is incomplete and would fail on host as well.
Being so arrogant when requesting help is useless.

BTW, you would try a full pipeline like this:

gst-launch-1.0 rtspsrc location=rtsp://10.5.1.10/video1 ! queue ! decodebin ! videoconvert ! xvimagesink

@Honey_Patouceul this is a checked fact. Writing something that you know for sure to be true is not arrogant. Both machines are here next to me.

Thanks for your answer. It works :-)

Hi Honey_Patouceul,
Sincerely appreciate your help.
