<P><FONT SIZE=2>Hi Deon,</FONT>
</P>
<P><FONT SIZE=2>Yes we have succesfull importing of of about 100 TS streams/assets</FONT>
<BR><FONT SIZE=2>on a Kasenna Mediabase server all day long :) The MPEG2's we use are</FONT>
<BR><FONT SIZE=2>made with Mobius MPEG2 hardware encoders.</FONT>
</P>
<P><FONT SIZE=2>We had the exact same Kasenna errors you mention with MPEG2's produced</FONT>
<BR><FONT SIZE=2>with an older encoder SDK/driver where the transport PES size setting</FONT>
<BR><FONT SIZE=2>used in the encoder wasn't the optimum of 2024.</FONT>
</P>
<P><FONT SIZE=2>A transport PES size of 2024 is a multiple of 184 (188 - 4 header)</FONT>
<BR><FONT SIZE=2>this reduces/eliminates Zero Length Adaption Fields in the stream.</FONT>
</P>
<P><FONT SIZE=2>Zero Length Adaptation Fields seem to break many parser/demultiplexer</FONT>
<BR><FONT SIZE=2>implementations (Stradis analyser, Kasenna Mediabase, older Kraetel set</FONT>
<BR><FONT SIZE=2>top boxes etc.) despite the fact that this is legal MPEG!</FONT>
</P>
<P><FONT SIZE=2>So basically Kasenna has problems calculating the proper bitrate with</FONT>
<BR><FONT SIZE=2>Zero length adaption fields in the stream and mis-interprets the stream</FONT>
<BR><FONT SIZE=2>as being <64kbit and refuses to import. (It also can't calculate properly</FONT>
<BR><FONT SIZE=2>if the file to be imported is too small, let's say a few seconds in</FONT>
<BR><FONT SIZE=2>length and then it also gives the same error).</FONT>
</P>
<P><FONT SIZE=2>The optimized transport PES size also majorly improved streaming to all</FONT>
<BR><FONT SIZE=2>sorts of streaming clients (VLC, set top boxes etc.) from our platform.</FONT>
</P>
<P><FONT SIZE=2>So I suggest you take a look at the PES size that is used in the encoded</FONT>
<BR><FONT SIZE=2>files or perhaps the files you use are too small...</FONT>
</P>
<P><FONT SIZE=2>P.S. we even manage to encode/stream live MPEG2 and MPEG4 (x264) with VLC to</FONT>
<BR><FONT SIZE=2>the Kasenna server, and stream/cast this live (simulated or true multicast)</FONT>
<BR><FONT SIZE=2>using the Kasenna server and it's playable from VLC as well (and playing</FONT>
<BR><FONT SIZE=2>on-demand MPEG2 files with VLC from Kasenna server is still experimental).</FONT>
</P>
<P><FONT SIZE=2>Hope this helps..</FONT>

<P><FONT SIZE=2>Has anybody had success in loading video assets on a Kasenna Server?</FONT>
<BR><FONT SIZE=2>I am using vlc to convert vob files to TS streams (required by Kasenna,</FONT>
<BR><FONT SIZE=2>MPEG2) but the server rejects it with the message:</FONT>
<BR><FONT SIZE=2>"asset has a bit-rate less than 64 kbps"</FONT>
</P>
<P><FONT SIZE=2>Using VLC-0.7.2 on FC2</FONT>
</P>
<P><FONT SIZE=2>Any help much appreciated</FONT>
