My client is android device, netword bandwidth : 1000 kbs. When my device begin to play this stream then wowza return streaming from hight quality to low quality. [4M->2.3M->695 kps]. I want server alway switch streaming from low to hight quality first when begin playing.
You can re-arrange the smil to see if that makes a difference. If it doesn't, there is not a way to change the way the device switches.
Looking at the names of your files, they don't look like different bit rate versions of the same video. Each video in an ABR set also has to be key frame aligned. Take a look at the Expression 4 Encoder pre-sets in this article.
The order of the streams in the playlist.m3u8 url should match the order in the smil file. You can confirm this by retrieving the playlist.m3u8 url in a browser and then opening the saved file in a text editor.
As Jason has mentioned, if changing the order does not help then it will be the player that is deciding which bitrate to play first. Wowza just presents a list of urls to the player. Wowza has no control over which url the player will actually request.
Thanks for your reply, i order streams in smil file and it works fine, player choose low bitrate first. I dont think there is simple way to resolve this problem like that. Many thanks. :)
