The samples I've seen don't use 11025, they use 0
(FLV_SAMPLERATE_SPECIAL).  Either way it is supposed to be ignored by
Flash Player, so it might not matter.

I also submitted a patch for this on 6/21.
[PATCH] muxing speex in flv

But I think it needs to be modified to enforce 2 frames-per-packet.
That could be parsed from the extradata, which is currently not used
because FLV doesn't write a speex header.
