Example of a FLV file with Speex-encoded audio?

Can anyone point me to an example of a Flash video file with a Speex-encoded soundtrack, freely downloadable from somewhere on the web?

Video can be in any codec (ideally none.)

I am trying to develop an application to generate such a file programmatically and would like a valid example to compare with my output for debugging purposes.

This link c开发者_如何转开发laims to be Speex in FLV, but it doesn't work in any of the players I tried it in.

This file is readable but allegedly contains a bug (but I don't know what it is)

A possible solution could be to generate your own files using a flv muxer. You could try with ffmpeg, it should be something like ffmpeg -i blah.avi -i blah.mp3 -vcodec copy -acodec copy out.flv. There is a discussion about this approach (for a different format) here.

audio-only-speex.flv over here plays for me: http://streams.videolan.org/issues/2973/
