Re: saving video on SD card
no I copied and pasted the file location into the box and pressed run to upload the firmware. I tried it again as you requested and it still doesn't work.

Re: saving video on SD card
Hmm.. I made sure that the SD card was firmly in place, but I still have the same problem. I now also get an EIO5 error after I reconnect the camera... I will try using maybe on older firmware?

Re: saving video on SD card
I did update the firmware (it says 2.8.0). I reformatted and it ran fine, then I tried to run again and the problem happened again. I reformatted again, and then the problem still happened. So yeah, the problem's still there.

Re: saving video on SD card
As a matter of fact, even the example programs "mjpeg.py" and "gif.py" has the same problem... So there might be some other problem...

Re: saving video on SD card
Don't you mean 10 seconds? Yes I am using the new firmware. I formatted and cleared out the SD card before using it with OpenMV but I don't think that's the problem because it's the camera that keeps disconnecting from the IDE. I don't think it's due to the cable because I have tried several already...

Re: saving video on SD card
Same code, but without the timestamps: import sensor, image, time, pyb, mjpeg sensor.reset() sensor.set_pixformat(sensor.RGB565) sensor.set_framesize(sensor.QVGA) sensor.skip_frames(time = 2000) m = mjpeg.Mjpeg('openmv_video.mjpeg') clock = time.clock() time = [0] start = pyb.millis() while(True): c...

Re: saving video on SD card
so is it impossible to get the timestamps? because if I do it in another file (i assume you mean another python program), then it won't be the timestamps for the same video...
Also, the program still did not work with the new firmware...

Re: Saving video and timestamps
I know, but I ask because the code wasn't very well commented/documented. So like what's the output? It prints some but what is that? And the input is the OpenMV script?
Code: Select all
tx_buf(tx_len)

Yes, I am also interested in this functionality. I want to use lucas-kanade algorithm in OpenCV on the OpenMV camera.

Re: Saving video and timestamps
What is the usage of this script? Also, is it possible to save a video using this script? Is it possible for the data to be processed by another program, like an OpenCV program?

Re: Saving video and timestamps
Is it possible to convert it back to video stream using python. Unfortunately, I do not use C. I have never used serial before (except with an Arduino I think).

Re: Saving video and timestamps
Thanks, but this doesn't allow me to access the timestamps for further processing... I would now have to do some OCR or something to access it? Is there not a better way?

Saving video and timestamps
I am trying to save a video, and also save its corresponding timestamps from openMV to my computer. How exactly would I do that? I know I can save a video with the frame buffer, but that does not have timestamps. I could record the timestamps and save them along with the video onto an SD card, but i...
