Topic:
Adobe Flash;;Apache Web Server
I am streaming video via HDS from an Adobe Media Server 5.0. (I could use RTMP).
I have a 90-minute stream encoded at 8 different bit rates...from 300kbps to 5500kbps.
Some wireless connections will not play a steady stream without frequent pauses to buffer content. The buffering problem is not a function of the server because I am able to stream as much as 7500kbps when on a hardwired connection.
Here is what I've observed. If the f4m file specifies only a single bit rate, the buffer is set to 10.00 seconds and a 900kbps file streams fine to my problematic wireless connection.
<media href="../../hds-vod/Homepage/Homepage-0900.f4v.f4m" bitrate="900"/>
If, however, the f4m specifies any two or more bitrates, then the buffer is always set to 4 seconds and my problematic wireless connection will not sustain the delivery rate.
<media href="../../hds-vod/Homepage/Homepage-0300.f4v.f4m" bitrate="300"/>
<media href="../../hds-vod/Homepage/Homepage-0900.f4v.f4m" bitrate="900"/>
It would be acceptable to hard-wire the buffer size to 10 or even 20 seconds but I do not know how to do that.
Any guidance appreciated.

I have seen those materials. After lots of experimenting I found that if I specify a single bitrate in the f4m then I can override the buffer time. If I specify two or more bitrates then the player automatically manages the buffer time. I have not found a way to override that buffer time and still specify two or more bitrates.
