RTSP feed issue

[ktsi]

Hi. The detection works fine for YouTube vids but when trying rtsp feed it freezes after about 2 sec. I am watching the feed simultaneously on another pc so I know the feed is up and running. Any ideas?

I am using a Mac M1.

Hi, can you add the error message or any warning at the terminal or at the front end? Or is it stopping abruptly?

Hi there,

Thanks for getting back. Well the image freezes after about 1 -2 seconds. Strange thing is that the logs freeze at the same time but after a while I see an error message and logs start again and then freeze again. Image on the web app is frozen all the time after the initial working period.

Look at this sample:

BTW, I tried with another RTSP feed but I have the same behavior.

Are you trying this on a GPU-assisted system?

The inferencing of a video in this system requires a high-end system with at least 4 GB GPU.

[ktsi]

It's a MacBook Air M1 with 8 gigs of total ram/vram.

[rampal-punia]

👍Yes, you already mentioned that. At my end, I am able to receive the RTSP stream and run detection and tracking.

As you mentioned the error.

0: 384x640 3 persons, 1 tv, 46.0ms
Speed: 1.3ms preprocess, 46.0ms inference, 0.6ms postprocess per image at shape (1, 3, 384, 640)

[h264 @ 0x12763fc20] error while decoding MB 16 11

After the error msgs, it is still performing detections, as here:

0: 384x640 3 persons, 1 tv, 62.1ms
Speed: 4.5ms preprocess, 62.1ms inference, 0.5ms postprocess per image at shape (1, 3, 384, 640)

0: 384x640 3 persons, 1 tv, 62.1ms
Speed: 4.3ms preprocess, 62.1ms inference, 0.5ms postprocess per image at shape (1, 3, 384, 640)

0: 384x640 3 persons, 1 tv, 45.4ms
Speed: 1.5ms preprocess, 45.4ms inference, 0.5ms postprocess per image at shape (1, 3, 384, 640)

So, it is running but the display is not correct... is this what you mean...

Display is frozen. That is the issue. Since logs indicate it is still detecting, what could be the cause?
