Potential Memory Leak Issue #42
Description
First of all, thanks for your work on this plugin. 🙏🏻
Having said that, I think I have stumbled upon a memory leak problem. When I use data mode (on iOS), the page memory is always increasing (as seen in the Safari Web Inspector) and, eventually, the application crashes. To try and troubleshoot this problem, I installed the cordova-plugin-memory-warning-ios-android plugin and I do receive memorywarning events repeatedly until the crash.
To alleviate the problem, I tried calling frame.recycle() in the onAfterDraw callback but it does not change the situation. By the way, frame.image and frame.element both return undefined in my setup.
When I switch to file mode, I do receive the occasional memorywarning event but the page memory usually goes back down and it does not crash. However, file mode causes me another problem which I reported in #29.
Anyway, if it was possible to free a frame's memory when we are done with it, I would be a very hapy man. Thanks in advance for your help.
P.S. If it helps, here are the options I'm using:
{
canvas: {
width: 1136,
height: 640
},
capture: {
width: 1280,
height: 2272
},
hasThumbnail: true,
thumbnailRatio: 1/4,
cameraFacing: "back",
}
