Erik Thomas commented on FLEX-33374: ------------------------------------ And yes, I understand the spark VideoDisplay leverages OSMF, including MediaPlayer and MediaElement and the defect may belong to OSMF. I will download and debug their sources and see if I can find something. > 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. -- This message is automatically generated by JIRA.
