Cameraview: Crash on camera recording on Xiaomi Redmi 8, Android version 9

[Radcat501]

Hi!

I implemented a fragment, which recording video, pack data to MultipartBody and send it to server. This workes fine on Xiaomi Mi Play with Android 8, but on Xiaomi Redmi 8 with Android 9 i faced a crash, and i still cant find solution. The crash is produced when i am pushing a button to start recording. Here is stacktrace:

E/MediaRecorder: start failed: -19
E/MediaRecorder: stop called in an invalid state: 0
E/CameraEngine: onVideoResult result is null: something went wrong. java.lang.RuntimeException: start failed.
java.lang.RuntimeException: start failed.

at android.os.Looper.loop(Looper.java:201)
at android.os.HandlerThread.run(HandlerThread.java:65)

And here is my CameraView settings in xml:

  <com.otaliastudios.cameraview.CameraView
        android:id="@+id/camera_view"
        android:layout_width="@dimen/match_constraints"
        android:layout_height="@dimen/match_constraints"
        app:cameraAudioBitRate="4000000"
        app:cameraAudioCodec="aac"
        app:cameraFacing="back"
        app:cameraMode="video"
        app:cameraVideoBitRate="4000000"
        app:cameraVideoCodec="h263"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

And my usage in fragment:

 image_view_record_video.setOnClickListener {
            image_view_record_video.animateInvisible(1000)

            saveFile = File(requireContext().getExternalFilesDir(Environment.DIRECTORY_DCIM), "video.mp4")
            startRecordingTimer()
            camera_view.takeVideo(saveFile!!, 30000)
 }

camera_view.addCameraListener(object : CameraListener() {

            override fun onVideoTaken(result: VideoResult) {
                super.onVideoTaken(result)
                val requestFile = saveFile!!.asRequestBody(("multipart/form-data").toMediaType())
            }

})

Also i am provided next permissions:

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.RECORD_AUDIO"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

Will appreciate any help for solution of this problem. Thanks!

Is this crash is also occurring with camera 2 engine ?

[Radcat501]

I dont know, but ill try and inform you about results.

[Radcat501]

Still same result. I added app:cameraEngine="camera2" in my xml, and when i start video recording, i got this stacktrace again:

E/MediaRecorder: start failed: -19
E/MediaRecorder: stop called in an invalid state: 0
E/CameraEngine: onVideoResult result is null: something went wrong. java.lang.RuntimeException: start failed.

As result, video doesnt recorded.

@Radcat501 I am facing the same problem with Xiaomi Redmi note 7 running on Android 10 . Did you solve the problem ?

[Radcat501]

@achreffaidi still not, but i suggest, the problem is in new File creating in Android versions above 8. Looks like File does not properly created, so CameraView cant start recording.

[achreffaidi]

@Radcat501 in my case, it works for the Selfie camera but Fails for the Main Camera. for some version under 2.6.4 it fails for both.

[achreffaidi]

And yesterday it randomly worked with version 2.3.0 and when i rebuilt the project today the problem is back

[achreffaidi]

@Radcat501 Updates ! I found the reason behind that exception. In my case it's because i am running ExoPlayer in another activity and i guess both of them are using Hardware acceleration for video. my temporary fix was adding
onPause(){ player.stop() }
to the activity that using ExoPlayer.
and that works for me ... but it created another problem when i try to run the media player again.

[Radcat501]

@achreffaidi looks like in my case removing app:cameraVideoCodec="h263" removed the crash.

@achreffaidi looks like in my case removing app:cameraVideoCodec="h263" removed the crash.

@Radcat501 Following your steps, i fixed the problem by setting app:cameraVideoSizeBiggest="false" . I think recording the video using 48MP camera in Biggest video size is what required using the hardware acceleration . Though it's just a temporary fix.
