erik Here is the link of the dump and code,
https://drive.google.com/drive/u/1/folders/1e7gqpPiIWf40YNNkfOvkihGs5RrKrLkt?dmr=1&ec=wgc-drive-hero-goto

I produced it today. 3 streams, 10fps, mjpeg. script node.

Jjkchen46033 · 2025-03-12T23:26:01+00:00

Never mind. I upgraded to 28 successfully. My Python environment screwed up.

Jjkchen46033 · 2025-03-12T22:20:30+00:00

Can someone tell me how to upgrade bootloader to 0.0.28? I used device manager, danger zone, and I also used example code inside depthai-python, but there is no 0.0.28 version when it trying to upgrade.

For example, when the version on the device is 24, it can upgrade to 26, but not 28, when I run those programs
When I am at 26, it does not show 28 to let me upgrade, when using those programs.

I got this message listed below when I run my program. I want to fix that.

erik Can you tell me how to upload?

Jjkchen46033 · 2025-03-11T18:55:31+00:00

erik Here is the dump. Let me know if you need additional info. Thanks a lot for your help.

My pipeline setup this way: poe, 3 lens, 3 jpeg encoder, all 10fps, two monos 720p, rgb 1080p, jpeg to script node, pumping out urls: /mjpeg, /left, /right, all in mjpeg multipart frames.

This dump is produced today.

Jjkchen46033 · 2025-03-10T22:40:31+00:00

I have a similar problems. I run a pipeline of three cameras (rgb, two monos), 10fps, 720p, sent to jpeg encoder, and the pipeline will crash in less than 20 minutes. It crashes when there are some movements in the scene. I got crash dumps most of times and sent one to the forum already. but no much of concrete response from Luxonisc. Basically all of the dumps mentioned the words: "thread, memory pointer, synchronization". I downed the pipeline to 6fps, same thing happened.

I never expect things like these would happen.
Please HELP. Luxonis.

i need to know how to capture a frame from mono. Not video, just a frame. A frame from left and then one from right. Thanks in advance for the helps.

Jjkchen46033 · 2025-03-04T21:19:53+00:00

I routinely get crashes while running a pipeline of 3 camera nodes, 3 jpeg encoders, one for color, two for mono, encoder's output to scripts. fps is 10 for all 3. Able to stream mjpeg to 3 different ruls, but would crash if running it for about 25 to 30 minutes. Dump report json says "frame pointer", "thread", "waiting for semaphore".

The host message said "ping was missed"

Here is crash dump:

code I used for is here:https://github.com/luxonis/depthai-experiments/tree/master/gen2-rtsp-streaming, and i followed the exact sequence. and I used ffplay to play the stream.

Anyone with successful experience with GEN2-RTSP-Streaming code (under depthai-experiments)? I ran the code but the video is very choppy. I am trying to build a rtsp stream. Thanks.
