HI, All
I'm trying to play with the video recording lib https://www.b4x.com/android/forum/t...d-in-b4a-6-jan-new-lib-files-in-post-48.60859.
Sample is working OK. But when i try to make my simplest sample
in my separate project - the first starting (avc1.setStartStopRecording) kills the app with error:
The lib shows for a second:
"Fail in prepareMediaRecorder".
Runtime permissions to PERMISSION_CAMERA and PERMISSION_RECORD_AUDIO are OK, and manifest also.
But the author sample is working on the same phone !!!111 I do not understand what the trouble is...
