[bloop16]

Hello, I can`t run the stream, always get the Error:

What am I doing wrong?

Thank`s for helping!

[rzeldent]

Hi bloob,

First time I see this. See the list of error codes

However, values for size etc.. seem reasonable so unfortunately cannot tell you what you're doing wrong...

Error 12 is ENOMEM, but the heap looks good. So maybe lowering the image size or buffer might help?! Maybe an update of the arduino esp32 environment?

Let me know or update the issue if you find something?!

[bloop16]

Hi rzeldent, I think I could enclose the issue. Sry, first time I’m using a Sketch like this.

I’m triggering the rtsp stream with motioneye, after erasing the board compliantly and build the sketch again it seams to work. Also I had to set the camera options in motioneye to tcp. Has been set to udp.

But I haven’t been able to open the connection over the browser and iFrame.

A notier problem i have is that the camera ssh log is writhing a message that the picture is send about every 170ms and writing an error that it’s running out off memory. (Sry not at home) But stays working. I’m not able to change the frame rate. The camera isn’t reacting on a change in motioneye. Is it possible to change the rate off sending frames?

thy for helping bloop

[rzeldent]

Hi bloob,

The framerate can be changed in the web GUI. See the section about setting up.

You could consider, as the rate is now 170 ms, to set it to 200ms, so 5 frames per second. Maybe this gives the esp some time to "breathe"

Kind regards,

Rene

Thanks again! I´ve tried to reach the /config site, but always getting the answer Server already running. What can i do to reach the config site again?

I suspect you're connecting to motion eye web server. Is this possible?

You can see the IP of the ESP32CAM in the logging when it is booting and connected to a serial terminal. Look for the line: [ 8056][D][WiFiGeneric.cpp:991] _eventCallback(): STA IP: 192.168.1.194, MASK: 255.255.255.0, GW: 192.168.50.1 Here in bold is the address.of the ESP32 CAM webserver, probably another address in your setup.

Connect using a browser on the same subnet to this address with a web browser using HTTP. Here you should be able to log in and configure the device.

No, I’m connecting to the Cam IP with http://192.168.0.49/config. The motioneye connection is closed. A reboot off the cam also didn’t help.

[SteveWiFi]

Just stopping by to say that I'm also affected by this...

I installed the latest PlatformIO using pip and set it all up using the command line (not that I think it'll make a difference).

I am wondering if there's been a change in the ESP32/Arduino code which has caused this?

I tried all low resolutions and low frame rates and nothing I tried resolved the problem.

[rzeldent]

Hi Steve/bloop,

I just did a complete rebuild (using platformIo), retested the current develop with the latest espressIf/Arduino code and I do not have any issues. Tested the build-in snapshot url and tested with VLC. No problems with both.

Could you explain a bit more what you're doing with motioneye? Can you confirm it works with VLC?

Kind regards,

Rene

[SteveWiFi]

I'm not doing anything with Motioneye ...

I built the code and installed it to my ESP32-CAM (ESP32-S, AI Thinker Camera), used VLC to connect to the RTSP stream and got several pages of the UDP errors ( [ 46818][E][WiFiUdp.cpp:183] endPacket(): could not send data: 12 ) as per the initial issue.

I have two of them and can confirm that it happens on both, so I can rule it out being a board issue.

This was the packages used at build time:

• framework-arduinoespressif32 @ 3.20006.221224 (2.0.6)
• tool-esptoolpy @ 1.40400.0 (4.4.0)
• toolchain-xtensa-esp32 @ 8.4.0+2021r2-patch5

Hi Steve,

Yes, I also saw a few of them but everything works normal; streaming is working fine. I do not know where they originate from but it does not seem to be a problem... Is it?

Hi Rene,

Given that I replicated it on both boards, I could only guess that there's a bug in one of the dependencies I used to build it.

I was hoping we could compare which packages we built it with to narrow it down.

[Drizzt321]

So I'm seeing the exact same issue, recent checkout and using VSCode/PIO as per your instructions on the README. Trying to play with VLC, getting lots of lines of that same UDP error.

My CPU model ESP32-D0WDQ5 rev. 3, 4MB PSRAM, 640x480 resolution, 100ms frame rate (10fps), 2 buffers, JPEG quality 12, using WROVER KIT camera type. Free Heap is 131.20 KB, Max free block 75.99 KB.

When I hit the /snapshot endpoint, I get a JPG, but it sometimes takes multiple seconds to load up. According to the Network tab in debug mode, it can be >1s to upwards of 8 or 9 seconds to completely receive/display the image. Seems split between Waiting for server response, and Content download. So I'm thinking something is just taking waaaaay too long, maybe the JPG library? Maybe initiating the read from the camera?

I'm watching the log output via Serial Monitor, not seeing any errors.

 *  The terminal process "C:\Users\drizzt\.platformio\penv\Scripts\platformio.exe 'run'" terminated with exit code: 1. 

I went into the platformio.ini and change the lib_deps to rzeldent/micro-moustache @ 1.0.0, and now it's building again. Supposedly wasn't a breaking change sigh

[rzeldent]

Hi Drizz,

Strange, did you do a pull the repo? The automatic CI build is working fine and just retested it with a fresh clone. But yes, some code has been replaced recently that was already available in a library. The current develop should compile with micro-moustache 1.0.1.

Kind regards,

Rene

[Drizzt321]

@rzeldent I hadn't updated from repo to local, just did, and that fixed the compile issue.

Hasn't fixed the UDP error unfortunately, though.

[Drizzt321]

So, got an RTSP stream to work, 1 buffer, 640x480, quality 35 (is 1 low or high?), 100ms frame rate (10fps).

However it tends to stutter, seems that the CPU can't keep up when the inter-frame changes seem to be a lot?

Strangely, when I tried 1280x1024 q=15 (lower seems to be better quality), I did get that to manage to work. It started to connect, gave the UDP error, but I let VLC continue, and it re-initialized and then started to playback the video. Something really strange seems to be going on.

While it's running, I checked, Free Heap: 128.42 KB, Max free blocks: 75.99 KB. Does run kinda slow/jerky. Trying at 33ms frame rate (30.3fps), sometimes slightly smoother, mostly about as jerky. I wonder if it's the CPU readout, or if the current compile only is using 1 of the 2 cores rather than spreading the load, or what.

When I switched back to 2 buffers, I got the UDP error spamming the output.

Just some more data, hope this helps some. Really would love to get this to work, this is much better sized than an RPi Zero 2 W + HQ camera module for my needs.

[rzeldent]

So it is the line: 17:11:43.764 > [ 46818][E][WiFiUdp.cpp:183] endPacket(): could not send data: 12

12 should be ENOMEM but there is enough heap space available so strange. However, mention at https://github.com/espressif/esp-idf/issues/6852 it states that an error 12 is returned when the client is disconnected. So more investigation needed?!

int WiFiUDP::endPacket(){ struct sockaddr_in recipient; recipient.sin_addr.s_addr = (uint32_t)remote_ip; recipient.sin_family = AF_INET; recipient.sin_port = htons(remote_port); int sent = sendto(udp_server, tx_buffer, tx_buffer_len, 0, (struct sockaddr*) &recipient, sizeof(recipient)); if(sent < 0){ log_e("could not send data: %d", errno); return 0; } return 1; }

[Drizzt321]

@rzeldent so that's ready for me to do a pull and recompile?

Would it be helpful for me to do a Wireshark recording?

[rzeldent]

Hi Drizz,

I just merged 10 minutes ago so you can use the develop branch. So, yes, that would be sufficient. I'm now updating some names in the config and later this evening will merge that also.

Enjoy!

What client are you using to receive the stream? VLC?

[Drizzt321]

Yes, VLC to test, then I'll be using Frigate NVR for long term usage. But validating it works and positioning/view/etc with VLC first.

[rzeldent]

Strange, over here it works fine with VLC on the same WiFi network. I see in the logging that your device has PSRAM (There is some variation in the ESP32CAM modules) so this is fine.

I see in the logging a gap of 26 seconds where no data is sent. This is strange especially because streaming should start after the play. Do you have maybe some UDP filtering in place?

[Corton]

Hey, I am also having the UDP packet issue. Camera initializes, I can access the web gui, change the settings, but if I try and connect to the rtsp stream via VLC I get the error below. I originally thought it was the new pfsense router I had setup in the last week, but I swapped back to my old router and the same thing. I can connect to all my other, non-esp32 cameras via RTSP just fine as well.

EDIT: I have the same problem on all 3 of my ESP32-CAMs.

[lejibxl]

I had the same problem, I added an external antenna and it greatly reduced the problem

[WarHawk8080]

Either it's a power issue (need a 22uf capacitor on power) or too weak signal from wifi

[rzeldent]

I removed the code to check for OTA updates. This is in the develop branch. This might help to increase the performance of the camera (packets sent) Can you notice any improvements?

[rottaran]

I can add an observation: We use the LwIP networkstack on ESP32-S3 with ESP-IDF 5.1.2 but have a custom communication backend that is not related to the ESP-IDF Wi-Fi driver. Our transmit callback that handles outgoing messages from LwIP down to the phy interface always succeeds. But the iperf UDP benchmark gets this ENOMEM from sendto() after 4 datagrams and succeeds in the following calls. It fails very rarely a second time. The issue only appears if the datagram fits into one Wi-Fi frame, for example with 100 Byte datagrams and also 1400 Byte datagrams. The issue disappears if the datagram is too big and IP fragmentation is used. My conclusion is, that the UDP ENOMEM is caused by LwIP and is not related to the Wi-Fi driver and all its settings.

I walked down the sendto implementation and placed debug messages on all places where an allocation could fail and ENOMEM is generated. This lead to no addiotinal outputs so far. I must have missed something.
