ESP32 Camera slow video (turn on subtitles)

SOLUTION: This issue is caused by anything attached IO0. By removing cable from IO0 ESP32 cam video is super fast. IO0 has to be connected to GND when uploading sketch. As you can see on video I have ESP32 in breadboard. IO0 is then connected to few centimeters of cable inside of breadboad. Removing ESP32 from breadboard solved the issue. (Credit goes to Jan, see the link bellow) ################ I bought a ESP32 Cam from eshop. I uploaded a demo sketch CameraWebServer and it worked but the video was very slow. I experienced FPS around 0.4. Which was far from 24 frames per second. I have watched many Youtube videos and in all of them their have more than 10 FPS depending on the image size. I though that my ESP32 was faulty and then I found that FPS dramatically increased when I touch with my finger near by antenna. In this video you can see how FPS increase every time I touch ESP32 and drop again when I do not touch ESP32. Wrapping part of ESP32 into antistatic bag also increase video. However not so much as when I touch it with my finger. This issue was also described in comments of following articles: https://robotzero.one/esp32-cam-ardui...   / aithinker_esp32_cam_slow_video_stream_try   https://github.com/espressif/arduino-... Here is the snippet of solution. Credit goes to Jan. Hmmm… this sounds familiar. In my setup I have the IO0 signal connected through a few cm long wire to a button going to ground. Framerate is horrible, then I read this post, noticed that when I touched all the headers with my fingers, framerate increased. So I searched for what this could be and noticed that the IO0 line isn’t for the bootloader only. Adding some extra pullups to IOo didn’t help either. Pushing the button during streaming stops it all. So I figured that the quickest way to solve this was to remove the wire to my button. Then everything worked beautifully. So to make a long short short, don’t have anything connected to IO0 during runtime (of the example as shown here)! According to my multimeter which doesn’t measure 0 or 3.3V it measures something in between. I wouldn’t be surprised if this is a high frequency signal (clocksignal) of some kind, that may not be disturbed by adding any kind of load. A simple wire can add like a capacitance. The funny thing is, that I cannot find a decent schematic or some document explaining what IO0 is and does during runtime.
