correct video orientation in fixed portrait app

[myousefi1368]

hi.
i dont want to use android:screenOrientation="sensor" because i want to use only one layout for my activity and only rotate icons programmatically in the class.
i can get correct phone orientation state by onSensorChanged method and handle icon rotation works good.
but i cant get landscape video output from stream anyway. i try many ways but no success!
could you help me please?

orientationHelper.currentOrientation.observe(this) { orientation ->
      if (lastOrientation != orientation) {
        lastOrientation = orientation
        rotateIconsOnly(orientation)
        val rotationAngle = OrientationHelper.getRotationAngle(orientation).toInt()
        viewModel.updateOrientation(rotationAngle)
        Log.d("MainActivity", "Orientation changed to: $orientation, Angle: $rotationAngle")
    }
}

in lanscape mode the value of rotationAngle is 270 in my app:
Phone camera start stream using rotation: 270 degrees w:640 - h:360
Phone camera RTP connection started: rtmp://80.191.242.19:1935/live/test
Phone camera RTP connection success

i solved it by modifying GlStreamInterface.kt to:

private val sensorRotationManager = SensorRotationManager(context, true, false) { orientation, isPortrait ->
        if (autoHandleOrientation && shouldHandleOrientation) {
            Log.d("mylogs","orientation:$orientation isPortrait:$isPortrait")
            if (orientation == 0 || orientation == 90) {
                setIsStreamHorizontalFlip(false)
                setIsStreamVerticalFlip(false)
            } else if (orientation == 180 || orientation == 270) {
                setIsStreamHorizontalFlip(true)
                setIsStreamVerticalFlip(true)
            }

            var final_orientation = orientation
            if (final_orientation == 270) {
                final_orientation = 90
            }
            if (final_orientation == 180) {
                final_orientation = 0
            }
            setCameraOrientation(final_orientation)
            setIsPortrait(isPortrait)
            if (final_orientation == 90) {
                setIsPreviewHorizontalFlip(true)
                setIsPreviewVerticalFlip(true)
            }
            if (final_orientation == 0) {
                setIsPreviewHorizontalFlip(false)
                setIsPreviewVerticalFlip(false)
            }
        }
    }

and

// render preview
    if (surfaceManagerPreview.isReady && mainRender.isReady() && !limitFps) {
      val w =  if (previewWidth == 0) encoderWidth else previewWidth
      val h =  if (previewHeight == 0) encoderHeight else previewHeight

      if (surfaceManager.makeCurrent()) {
        mainRender.drawFilters(true)
        surfaceManager.swapBuffer()
      }
      if (surfaceManagerPreview.makeCurrent()) {
        mainRender.drawScreenPreview(w, h, isPortraitPreview, aspectRatioMode, if (isPortrait) 0 else 90,
          isPreviewVerticalFlip, isPreviewHorizontalFlip, previewViewPort)
        surfaceManagerPreview.swapBuffer()
      }
    }

and

fun setIsPortrait(isPortrait: Boolean) {
    setPreviewIsPortrait(true)
    setStreamIsPortrait(isPortrait)
  }

and in the app:

genericStream.startPreview(surfaceView, autoHandle = true)

it is good to change the lib that can works good in fixed orientation activity too.
thanx

Hello,

Thank you for share it.
Currently you can do steps 1 and 3 without change the library but I will do a way to do the steps 2 so you can do it without modify the library.

thank you
please tell me how to do the 1&3 from 4 steps

You only need set autoHandleOrientation to false when you Create the GenericStream class and then create an instance of SensorRotationManager like you did.
Using the callback of that new instance you can get the glStreamInterface and modify orientation, setPreviewIsPortrait(true) and setStreamIsPortrait(isPortrait) as you need.

I will create a new setter to modify preview rotation to cover the other step
