    MultiBitrate San Jose stream from wowza




      I am developing web flash player using OSMF.

      I have need feature that player supports multi bitrate San Jose stream.


      As streaming server is used wowza 2.2.4. and test url for stream is:


      (There are used two diferent video streams with diferent bitrates to better understand when happens switching.)


      Main problem is, that player does not corectly switches streams.

      At start is played worst quality. Player compiled using OSMF 1.5, when it trys to switch stream to better quality, it looses video. Only audio is played.

      Using OSMF 1.6. stream switching is not happening at all.

      Using example player whitch comes with OSMF or one which comes with wowza (both compiled with OSMF 1.6), player behavior is the same.



      So question is - does OSMF support multiple bitrates for http streaming (san jose)? or wowza generated manifest form smil file  is wrong? or other ideas whats may be wrong?



      Here is smil used for manifest.f4m generation.


      <smil xmlns="http://www.w3.org/2001/SMIL20/Language">


              <meta base="http://live1.tiesraides.lv/live" />




              <video src="mp4:vdtv2" system-bitrate="49552" width="480" height="360"/>

              <video src="mp4:vtv_1" system-bitrate="970752" width="640" height="480"/>






      And here generated manifest.f4m



      <?xml version="1.0" encoding="utf-8"?>

      <manifest xmlns="http://ns.adobe.com/f4m/1.0">







          <bootstrapInfo id="bootstrap49552" profile="66" url="playlist_b49552_w13841143.abst"/>

          <media bootstrapInfoId="bootstrap49552" bitrate="48" url="media_b49552_w13841143.abst/">

          <bootstrapInfo id="bootstrap970752" profile="66" url="playlist_b970752_w13841143.abst"/>

          <media bootstrapInfoId="bootstrap970752" bitrate="948" url="media_b970752_w13841143.abst/">
