Invalid after MediaStoreOutputOptions is set

The format MP4 and name of the captured video are set through MediaStoreOutputOptions, but the format of the video captured by CameraX is 3gp, and it is not the name of the setting
My Android system is AndroidP, SDK is 28，CameraX Version is 1.2.2
*************************************************************************************
```
videoCapture?.let { vc ->
val name = "Video_${System.currentTimeMillis()}.mp4"
val contentValues = ContentValues().apply {
put(MediaStore.Video.Media.DISPLAY_NAME, name)
put(MediaStore.MediaColumns.MIME_TYPE, "video/mp4")
if (Build.VERSION.SDK_INT > Build.VERSION_CODES.P) {
put(MediaStore.Video.Media.RELATIVE_PATH, "Movies/Videos")
}
}
val mediaStoreOutput = MediaStoreOutputOptions.Builder(
requireActivity().contentResolver, MediaStore.Video.Media.EXTERNAL_CONTENT_URI
)
.setContentValues(contentValues)
.build()

recording = vc.output
.prepareRecording(requireContext(), mediaStoreOutput)
.withAudioEnabled()
.start(
ContextCompat.getMainExecutor(requireContext())
) {
Logger.d("testCamera", "camera recording event: ${it.recordingStats}")
}

}
```

Start with the MediaStoreOutputOptions and videoCapture output flow shown in the issue, then reproduce it on Android P with CameraX 1.2.2 using the provided ContentValues. Check the resulting video format and display name; done means determining why the configured MP4 type and name are not reflected, or documenting the limitation if the behavior is expected.
