SK-TDA4VM: Cannot store the ai demo video from the USB camera

James Lee

Part Number: SK-TDA4VM

Hello Ti,

I try to use the demo https://dev.ti.com/tirex/explore/content/edgeAI_academy_0_00_00_01_eng__all/modules/6_1_live_input_and_output.html

I want to store the video from the USB camera and I set the "output" in the "my_configuration.yaml":

output0:
sink: /opt/edge_ai_apps/data/output/videos/output_video.avi
width: 1920
height: 1080

After the demo run, the terminal appear

How to solve the issue?

Hi James,

Could you try changing the the extension from "avi" to "mkv" to see if this gstreamer error resolves?

Thanks,

Hi Fabiana,

I want to store the video as file while monitor the output on the screen.

If I use the format "mkv", the screen doesn't show anything.

Is there any method to show the output on the screen and store the screen output as a video file at the same time?

Hi James,

To show the output on your display and store as a video file you must set your outputs and flows to do so.

For example:

output0:
        sink: kmssink
        width: 1920
        height: 1080
    output1:
        sink: /opt/edge_ai_apps/data/output/videos/output_video.mkv
        width: 1920
        height: 1080

flows:
    flow0:
        input: input0
        models: [model0]
        outputs: [output0]
        mosaic:
            mosaic0:
                width: 1280
                height: 720
                pos_x: 320
                pos_y: 180
