Error: no matching function for call to 'OV2640Streamer::OV2640Streamer(OV2640&)'

streamer = new OV2640Streamer(cam); // our streamer for UDP/TCP based RTP transport

While trying to build this example using pio, I get the following error: error: no matching function for call to 'OV2640Streamer::OV2640Streamer(OV2640&)'
platformio.ini file contents I used:

[env:esp32cam]
platform = espressif32
board = esp32cam
framework = arduino
lib_deps = Micro-RTSP, ESP8266_SSD1306

It looks like there is no constructor defined that takes only one argument - the cam object.

Please advise on how to best get past this error.

Sounds a bit like a problem I had with Arduino IDE, when I copied the sketch the source catalog was not copied so the #include src/"OV2640Streamer.h" or similar failed. Does your build have OV2640Streamer.h mapped or in the path?

Same problem here while trying to compile with Arduino ide.
Has anybody found a solution?

Just had this same error with pio run How do we map OV2640Streamer.h ? Where is that located?

[dcmwong]

I found the answer by placing the example folder into the root folder so the src sits in the same place where all the .h files live. I had to install some dependencies and then pio run worked

I'm using pio in VS Code here and the resolved dependency has a two params constructor which is out of sync with this repo....

Example

streamer = new OV2640Streamer(cam); // our streamer for UDP/TCP based RTP transport

.pio\libdeps\esp32cam\Micro-RTSP\src\OV2640Streamer.h

#pragma once

#include "CStreamer.h"
#include "OV2640.h"

class OV2640Streamer : public CStreamer
{
    bool m_showBig;
    OV2640 &m_cam;

public:
    OV2640Streamer(SOCKET aClient, OV2640 &cam);

    virtual void    streamImage(uint32_t curMsec);
};

You should not use example in this repo with the library installed by plataformio.
Use the example in .pio/libdeps/esp32cam/Micro-RTSP folder instead

I got this error by mixing files from different Micro-RTSP, by different I mean from several githubs. It was solved by deleting all the files and using just the files from this very git.
