esp32cam to obs

ive played around with these a now and then.

you can get these on ebay for around £8.00
just decided if i can connect it to OBS

1st i followed this site to program the module
https://randomnerdtutorials.com/esp32-c ... duino-ide/

while you are adding your wifi ssid and pass.
scroll down and look for

Code: Select all

 //drop down frame size for higher initial frame rate
  s->set_framesize(s, FRAMESIZE_QVGA);

change to

Code: Select all

 //drop down frame size for higher initial frame rate
  s->set_framesize(s, FRAMESIZE_SVGA);

this just sets the default frame size
choices are
160x120 (QQVGA)
128x160 (QQVGA2)
176x144 (QCIF)
240x176 (HQVGA)
320x240 (QVGA)
400x296 (CIF)
640x480 (VGA, default)
800x600 (SVGA)
1024x768 (XGA)
1280x1024 (SXGA)
1600x1200 (UXGA)



one you have programmed the device and have its IP address you can use your browser to go to the server

ESP32-CAM-video-streaming-example.jpg (58.07 KiB) Viewed 7998 times

the stream address is http://YOUR_DEVICE_IP:81/stream

in OBS add a scene and in that scene add source and select browser in the URL input http://YOUR_DEVICE_IP:81/stream
you can play around wiht the frame size to suit

what my obs look like the esp32cam on the left

this is not a step by step guide. but it may help members who like to play

[m1cdq]

for the more tech minded I believe it can also be set up to do a RTSP video server

Lovely, another source to play with (well, 2 actually if China eBay delivers).
SHould work nicely with my old TalkTalk ADSL box, when I'm out portable

The two cameras have arrived, along with a handy USB programming board I spotted on https://bitluni.net/camProg. Saves a lot of messing, work in progress now.....

OK, trying to progress this as a handy little camera solution.
I've followed the tutorial to install the many 'ESP' libraries and have successfully downloaded a wifiscan program that returned all my local wifi sources, so I (a) know my bitluni cam-prog is working and that its talking to the chip that runs the wifi component.
Using 'get board info' comes back with BN:Unknown (bootleg Chineses copy??) VID 1A86 and PID 7523. Desptie having uploaded a sketch it still says upload any sketch to obtain SN. Last probably not of consequence.
When I try and compile/upload either the example listed above or the example in the ESP library (Camerawebserver) I get error messages at the end saying...
Global variables use 53488 bytes (16%) of dynamic memory, leaving 274192 bytes for local variables. Maximum is 327680 bytes.
Sketch too big; see http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing it.
Problem may be I can't find an 'exact match' for the ESP board I have (pictures attached). As its probably a clone board I'm working my way through the options listed hoping to find one that 'looks' like mine.....so far they compile process (which seems to take ages?? compared to 'most sketches') keeps fialing with Sketch too big....
Unless someone can shed light.....
TIA

I have a clone board - when compiling I use

#define CAMERA_MODEL_AI_THINKER and it works fine.

Also your pinouts are the same as my board. The DM may indicate DiyMore as the maker.

My Board ID gives same as you quote

I Use a USB to serial adapter set to 3volts for programming

File used esp32-cam-webserver-1.0
No changes to it other than the wifi ID entry

Assume using Arduino compiler - remember to select the correct board "AI Thinker ESP-32-CAM"
(under Tools Board)

Here is output from my compile

For OBS add source Browser Type in name - click OK - next enter url
put in http://192.168.0.244:81/stream your cam IP ADD obviously
then width and height click OK

Remember it only supports one stream.
Controls - use a browser - no port required as it defaults to 80
view just the stream in a browser - use same ip with :81/stream on end.

Thanks Bob, that might well progress things
EDIT.....as indeed it did, still a slow compile, but it (a) fits and (b) uploaded without any problems
Now to find it on my network once powered seperately from the cam-prog.
Gareth
EDIT AGAIN.....Spectacularly good for something that was less than a £5! Now to design a nice little case for it

[radiogareth]

Spoke a bit too soon I fear.....first device popped up directly on my router, second one programms fine (with the same code) but steadfastly refuses to connect to either my main unit or my portable unit (which the earlier one does with a repsogramming fo ID & PW).
Still, one works so for £10 its not a deal breaker....
QC perhaps....
But since I had salvaged the 2.4GHz PCB antenna from a dead Virgin Router and since the plugs matched, its now got a much stornger link to the router. which helps with the refresh rate.....

Use the serial monitor on the Arduino IDE to watch the start up when programmed.

So have board connected to IDE - select serial monitor - make sure com port and speed selected then press the reset button on the ESP board, make sure you have not got the ground link to IO0, and on the serial monitor display you will see diags and may tell you what is wrong.

Did you change the surface mount link next to the aerial plug ?, as it comes its normal position connects the onboard PCB aerial, in other position it connects to plug for external aerial.

Camera Ready! Use 'http://192.168.1.2' to connect

And no, I did not spot the jumper link for the external antenna - thanks. I've done a little researching on how to use the on-board LED (for e.g. lighting the subject at night) but not really found a simple solution to controlling it. Hack the PCB track to the control transistor, use bluetooth to control it and a couple of other options like motion triggered flash for wildlife camera etc. Surprised there isn't something light level controlled, from camera sensing perhaps or just an LDR.Its a powerful little board!
