Gaius Coffey closed FLEX-33410. ------------------------------- Resolution: Duplicate I have created a bug report here: https://bugbase.adobe.com/index.cfm?event=bug&id=3504086 Please take a look, use my supplied test script, and vote for the issue if you can reproduce it. G > NetStream jumps when playing on Android devices > ----------------------------------------------- > > Key: FLEX-33410 > URL: https://issues.apache.org/jira/browse/FLEX-33410 > Project: Apache Flex > Issue Type: Bug > Components: Spark: VideoPlayer > Environment: Android mobile > Reporter: Gaius Coffey > Priority: Blocker > Labels: netstream, osmf, video > > When playing videos using OSMF on Android devices, NetStream will skip the > final few seconds. This makes it impossible to use video commercially. > Steps to reproduce: > 1. Create a Mobile project similar to the below > 2. Run it on an Android device and watch the traces as the video gets to the > end > Replicated on all of Motorola Xoom, Nexus 7, HTC Desire... > package > { > import flash.display.Sprite; > import flash.display.StageAlign; > import flash.display.StageScaleMode; > import flash.events.Event; > import flash.events.NetDataEvent; > import flash.events.NetStatusEvent; > import flash.net.NetStream; > import flash.text.TextField; > import flash.utils.Dictionary; > import flash.utils.getTimer; > > import org.osmf.elements.ProxyElement; > import org.osmf.elements.SerialElement; > import org.osmf.elements.VideoElement; > import org.osmf.events.MediaErrorEvent; > import org.osmf.events.MediaPlayerStateChangeEvent; > import org.osmf.media.MediaElement; > import org.osmf.media.MediaPlayerSprite; > import org.osmf.media.URLResource; > import org.osmf.net.NetStreamLoadTrait; > import org.osmf.net.NetStreamSwitchManagerBase; > import org.osmf.traits.MediaTraitType; > import org.osmf.traits.TimeTrait; > [SWF(backgroundColor="#272727")] > public class DebugAdvert extends Sprite > { > public function DebugAdvert() > { > super(); > > // support autoOrients > stage.align = StageAlign.TOP_LEFT; > stage.scaleMode = StageScaleMode.NO_SCALE; > stage.addEventListener(Event.RESIZE,doResize); > > // Textfield for logging > tf = new TextField; > tf.backgroundColor = 0xffffff; > tf.multiline = true; > tf.background = true; > addChild(tf); > > // MediaPlayerSprite for video display > mp = new MediaPlayerSprite(); > addChild(mp); > > // Position everything for the first time. > doResize(null); > > // Add OEF listener to update traces > addEventListener(Event.ENTER_FRAME,everyFrame); > > // Start the process going by adding a video > var ur:URLResource = new > URLResource(TEST_VIDEO_CONTENT); > var me:MediaElement = > mp.mediaFactory.createMediaElement(ur); > mp.media = me; > } > public const TEST_VIDEO_CONTENT:String = > "videos/TOYOTA_YARIS_MORE_VER2_30_TV.mp4"; > /** > * The threshold for a step between frames that will be logged > as an error. > * This should ideally be the same as frame interval, but will > * vary with device performance.
