Is not working perfomance units in the Delphi 10.3 release, could you see what the problem is?

narkoKast commented 5 years ago

Only crash ...

flydev-fr commented 5 years ago

@narkoKast Working here, see the screenshot from the mobile (Samsung J5 / Android 8.1 / Rio 10.3)

Probably not using an FMX.media.android drive for fps gain. As image is 3.4 fps, the problem occurs when you use it.

flydev-fr commented 5 years ago

With a resolution of 720x480 i got ~15fps. The screenshot is taken with a resolution of 1280x720.

Spelt commented 5 years ago

Way to slow.

I'll try to fix the Advanced app. I've heard that are some units missing.

You should have a stable 29/30 fps

Compiling with FastUtils.pas from Fast folder, I got 25,1fps with a resolution of 720x480, which is quite acceptable 👍

25fps

@flydev-fr Could you make this project available for download?

flydev-fr commented 5 years ago

@marcogps yes, I was going to do so once back at home. wait an hour or so.

flydev-fr commented 5 years ago

There you can grab the project : https://github.com/flydev-fr/ZXing.Test

narkoKast commented 5 years ago

I have checked new demo (Delphi RIO, phone: Android 6.0, LG-H815) If make scan ON I get debugger "FmxAdvancedTestApp.apk raised exception class illegal instruction(4)" and app crashed. If only change Resolution also get the same exception immediately.

Hi. Unfortunately there is an incompatibility somewhere in the fastlib.o files. I updated the home page: https://github.com/Spelt/ZXing.Delphi if there is a change to the situation I'll post an update.

Spelt commented 5 years ago

Hi all,

The problem is solved. The camera on Android is good again.

Download now your update.

Let us know your result!

flydev-fr commented 5 years ago

Thanks, I saw the message from E. van Bilsen and tested it this afternoon, it works great !

When I turn on the camera and return to ZXingAPP, There was a mistake. like This:

marcogps commented 5 years ago

It was excellent with the stitching done. It is not running at 30 fps, but at a lower resolution such as 640x480 it is around 21 fps

Thank you

flydev-fr commented 5 years ago

A test with a resolution of 1280x720 give me 26/30 fps 👍
