Erik Thomas updated FLEX-33374:
-------------------------------
Attachment: VideoDisplay.jpg
This is a screen shot of an AIR simulator for the iPhone. The video streams
immediately. If you run the same app on the device itself, with WiFi
connectivity and high bandwidth connection, it still takes a minute before the
video begins playing.
> spark VideoDisplay and VideoPlayer fails to stream video on mobile devices

> Key: FLEX-33374
> URL: https://issues.apache.org/jira/browse/FLEX-33374
> Project: Apache Flex
> Issue Type: Bug
> Components: Spark: VideoPlayer
> Affects Versions: Adobe Flex SDK 4.6 (Release)
> Environment: FlashBuilder 4.7 on Windows 7, iPad 3, iPhone 4, remote
> FMS 4.5 server, FLV Video source in 112K bitrate.
> Reporter: Erik Thomas
> Attachments: VideoDisplay.jpg, VideoPlayback.zip

>
> The spark VideoDisplay will not stream video from FMS 4.5, instead it appears
> to do progressive download instead, and it buffers the file for about one
> minute before it begins to play.
> However, the same code running in FlashPlayer on web, or in an AIR mobile
> simulator, the video properly streams and displays within seconds of playing.
> I understand VideoDisplay is not "optimized" for mobile, but that should not
> cause this behavior. I am in the process of debugging the spark codebase to
> find the root cause, but so far have been unsuccessful.
> So I attached a project that displays this behavior. Just unzip the file to a
> directory, start FB and point the workspace to the directory, open the
> project, build and run it first in an AIR simulator for an iOS mobile device,
> you'll see video instantly. Then deploy it in debug or release to an actual
> device. When you launch the project, you have to wait approximately a minute
> before the video will start playing.
> I'm assuming it's failing over to progressive download from streaming in some
> way, but I really have no idea what is causing the issue.
> I really don't care if the performance of the VideoDisplay isn't optimized
> for mobile, and a delayed start of several seconds would be fine, but one
> minute?
> If I find a root cause I will update this defect record with my findings as
> this is a blocker for us so that's my focus.
