- //haven't fully initialized pCurr and we attempt to set it to
- //point to the first block for this track. But that's not what

- //return end-of-stream, not (re)start from the beginning.
- //
- //One work-around is to send EOS immediately. We would send
- //the EOS the next pass anyway, so maybe it's no great loss. The
- //only problem is that if this the stream really does end one
- //cluster early (relative to other tracks), or the last frame
- //happens to be a keyframe ("CanSeekToEnd").
- //
- //The problem is that we need a way to mark as stream as
- //"at end of stream" without actually being at end of stream.
- //We need to give pCurr some value that means "you've reached EOS".
- //We can't synthesize the special EOS Cluster immediately
- //(when we first open the file, say), because we use the existance
- //of that special cluster value to mean that we've read all of
- //the clusters (this is a network download, so we can't know apriori
- //how many we have).
- //
- //Or, we could return E_FAIL, and set another bit in the stream
- //object itself, to indicate that it should send EOS earlier
- //than when (pCurr=pStop).
- //
- //Or, probably the best solution, when we actually load the
- //blocks into a cluster: if we notice that there's no block
- //for a track, we synthesize a nonce EOS block for that track.
- //That way we always have something to return. But that will
