FLVPlayback & FLV Multibitrate Problem?
Our QA department ran into an issue when testing dynamic streaming with multple encodings in the FLV format that results in a stream cannot be found exception thrown by the FLVPlayback component. An interesting note is that dynamic streaming works when we use F4V files. At first I thought perhaps this was a limitation with Flash, but when I traced the code inside the FLVPlayback component I realized that the video delivery using NetStream should be supported by the Flash video player. So I'm a little confused why this error is happening. We're using the SMIL playlist format to supply the FLVComponent with the videos. I've also tested each video with a direct RTMP connection and they playback fine, so there doesn't appear to be anything wrong with the server or the files.
I've included the sample XMIL playlists below.
