Can Screen Capture be improved? #23

hi @vuduong1124
Can you share block code to convert FrameBuffer to image
It seems this tutorial is not correct
System.Drawing.Image img = client.GetFrameBufferAsync(device, CancellationToken.None).GetAwaiter().GetResult();It seems this tutorial is not correct
(Well, I just tried this library out, I have been using python and an adb library for python before but wanted to give this library a shot).
About the tutorial not being correct, I assume you're reffering to the examples and that you get an error that
FrameBuffercan't be made into anImage? There's an explicit conversion implemented (there seems to be other conversions too , depending on need, not onlyImage).You can do either of this to get around this problem and make the compiler happy:
Image image = (Image) client.GetFrameBufferAsync(device, CancellationToken.None).GetAwaiter().GetResult();
or
Image image = client.GetFrameBufferAsync(device, CancellationToken.None).GetAwaiter().GetResult().ToImage();
This will, in theory, make it work - I assume this is the intended way to do it.
However, I get an exception when I execute the above code, trying to grab a screenshot (from a device with verified working ADB connection). The
Framebuffergets disposed at some point and the library throws exception about. I haven't tested much so I might as well mention it.I can see in the source code of the library where it does this but I haven't tried to understand why this happen. Also noted that there's no unit test implemented for
GetFrameBufferAsyncso maybe the error is actually a bug not being detected. But honestly, I don't know. (Actually, this is why I ended up here, to see if anyone else have mentioned this exception or if created an issue ticket for it.)- Reacted by Jens
It is good, Do you have plan to include this commit in release version.
