Two QML Video elements work fine on desktop but not on Android

Question

We want to have multiple simultaneous video playbacks in our application. This example below runs fine on Mac but on Android, I see only video in the left QML Video element.

I notice, from the signals, that both players enter the PlayingState.
I also note that, on Android, the status=MediaPlayer.Buffering while on Mac status=MediaPlayer.Buffered. However, the same statuses are also observed when a single Video element is used hence I don't think this difference is relevant here.

Is this a Qt bug or a platform limitation? Can I detect this platform limitation somehow (in order to adapt the UI accordingly)?

import QtQuick 2.5
import QtQuick.Window 2.2
import QtMultimedia 5.5

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")

    Video {
        id: v1
        width: parent.width/2
        height: parent.height
        anchors.left: parent.left
        source: "http://devimages.apple.com/iphone/samples/bipbop/gear1/prog_index.m3u8"
        onStatusChanged: console.log("Status V1 "+status + "//" + MediaPlayer.Buffering)
        onAvailabilityChanged: console.log("Availability V1 "+availability)
        onErrorChanged: console.log("Error V1 "+error + "//"+ errorString)
        onPlaybackStateChanged: console.log("PlaybackState V1 "+playbackState)
    }
    Video {
        id: v2
        width: parent.width/2
        height: parent.height
        anchors.right: parent.right
        source: "http://devimages.apple.com/iphone/samples/bipbop/gear1/prog_index.m3u8"
        onStatusChanged: console.log("Status V2 "+status + "//" + MediaPlayer.Buffering)
        onErrorChanged: console.log("Error V2 "+error + "//"+ errorString)
        onPlaybackStateChanged: console.log("PlaybackState V2 "+playbackState)
    }
    Component.onCompleted: {
        v1.play()
        v2.play()
    }
}
