I’ve run samples 9 and 10 successfully, but when I run sample 11, I see:

I’m not seeing a window pop up showing the video feed and potential labels, like in the JetsonHacks video which uses this example.

Any suggestions?

Hi Apollys, Do you run ‘export DISPLAY=:0’?

Also we encourage you to run TensorRT. Please refer to the samples:

tegra_multimedia_api\samples\04_video_dec_trt
tegra_multimedia_api\samples\backend
tegra_multimedia_api\samples\frontend

Yes, I have run the export display command. I will test sample 04 when I get the chance.

What command line parameters should I enter to run 04? I don’t see a sample video file anywhere to run it on.
