[Vorbis] DirectShow Filters

Tue Sep 28 02:31:02 PDT 2010

So this means the DirectShow filters are only useful for playing local Vorbis files now?

I’m sure I use to use these filters about 5 or 6 years ago with Oddcast encoded streams with no problems.  I take it this functionality was removed for some good reason?

I did a quick search through Edcast forums and I've found:
http://www.oddsock.org/openbb/read.php?TID=897

"anyway, having said that, one technique which oddcast uses is to 
physically stop and restart the vorbis stream on song changes. 
This is due to the fact that vorbis comments can only appear at 
the beginning of the stream, and so in order to change the song 
title, mid stream, oddcast must stop, reset the vorbis headers/comments, 
restart the bitstream. It does this on every song change. Clients that 
support this type of vorbis stream ("chaining" I beleive it's called) should 
handle this appropriately....does that clear it up at all ?"

Cheers,
Cristian.

As far as I remember Edcast was making Ogg Vorbis chained streams.
I have created a Trac ticked for this issue: https://trac.xiph.org/ticket/1740

The stream plays fine in Winamp, but in WMP it says it cannot play it at all.

I don’t understand why it would have different chains.  It a continuous stream encoded by Oddcast/Edcast to an Icecast server v2.3.1.

I’ve installed the DirectShow filters from this page www.xiph.org/dshow but my vorbis stream is not playing in Windows Media Player.

Actual stream URL.

ASX URL.

Can anyone shed any light?  Using Windows XP 32-bit.

Hi Ross,

I just did a quick test using Windows 7 and it played one song, afterwards
it stopped.  Does stationplaylist use chained Vorbis? 

Chained Vorbis is  unsupported by the DirectShow filters.

I have tested the above link using Mozilla Firefox 3.6.10 and the result
was the same, only one song was played.

Cheers,
Cristian.
