made some minor tweaks to the image saver class.
@jafal fiy I was hoping you would be able to use the image saver code I’d left to produce this solution.
now there were a few updates had to make to the code. My previous code would max frameRate at 10 fps, as it was always testing the save location first.
So checkLocation is called only once now in setup.
Then method logic2() update from logic() just takes the initial folder name and filename add a counter after the first save.
increments counter after every save this way you do not overwrite all your previous files.
Things to bear in mind. The cam stream I believe produces on 15 fps, whilst processing runs at 60 fps so you might get a lot of repetition in your frames alternatively you could test if your current frame is the same as the last this shouldnt cause too much problems in terms of speed as you should have 3 free framed to work with.
the following code should open a video stream on android and save the frames as a file of your choice in a folder of your choice.
Please note that I havent bothered to add functionality for deep folder structures. Though this could be added easily later. But its important to keep in mind.
Please refer to my previous posts on imagesaver for android if you want the basic code.
