Very low FPS when trying the AsyncCam example

[chewbaz1]

Hello

I tried using the AsyncCam example but I get very poor fps (1-2fps). When i use the standard example from espressif I get normal fps. Changing resolution doesnt help. I have an AI Thinker board and it gets very warm with this example. I am using PlatformIO and have tried upload with both AI thinker setting and Wrover setting but fps is bad on both. When I tried using arduino IDE i got a lot of errors therefore I use platformio instead.

Power: 5V

I would be happy if I recieved help with this issue.

Thanks

It is a very good library but I am also having the same problem

Same problem. cant made a HTTP+JS web joystick for RC Car via websockets with embebed stream video

Same here. I can get a v. good frame rate if I'm on StreamMjpeg, but the async example is depressingly slow!

When i use the standard example from espressif I get normal fps.

Do they offer an example with AsyncTCP?
If so, can you post a link?

I can confirm that the frame rate on the Async example from this repo is quite poor :(. Even when lowering the resolution.

To capture a static jpeg is actually quite fast. I modified the example to have a download button and the download is almost instant.

I attempted to characterize the performance of the library - I found in esp32cam-asyncweb.h this line auto frame = Camera.capture().release(); I slapped a println there and disappointingly found that it is only capturing a frame once per second.

Using platformio with the following settings:

[env:esp32cam]
platform = https://github.com/Jason2866/platform-espressif32.git#Arduino/IDF5
board = esp32cam
framework = arduino
upload_speed = 921600
monitor_speed = 115200
monitor_rts = 0
monitor_dtr = 0

lib_deps =
    AsyncTCP
    ESP Async WebServer
    yoursunny/esp32cam

Using this board.
