Subject [jira] [Commented] (FLEX-33374) spark VideoDisplay and VideoPlayer fails to stream video on mobile devices
Date Thu, 31 Jan 2013 15:45:12 GMT

    [ https://issues.apache.org/jira/browse/FLEX-33374?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13567731#comment-13567731

Erik Thomas commented on FLEX-33374:

BTW, I thought of tryng to use StageVideo but the problem there is, we display the video in
a popup container. StageVideo plays underneath the display tree and cannot be displayed within
a popup Flex container.

I'm also trying to workaround this with Netconnection, Netstream and Video classes instead
but it would be really cool to have VideoDisplay stream on mobile.

>                 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.
