Example 2 with CameraSession

use of org.telegram.messenger.camera.CameraSession in project Telegram-FOSS by Telegram-FOSS-Team.

the class InstantCameraView method createCamera.

private void createCamera(final SurfaceTexture surfaceTexture) {
    AndroidUtilities.runOnUIThread(() -> {
        if (cameraThread == null) {
            return;
