Thanks.

So I think we have a bug in the sample provided by BBC RD.

"Initialization segments being common means that all Representations in an
Adaption Set will have identically the same 'stsd' box. There will be one entry
in the 'stsd' box for each Representation. Representations encoded with
different "parameters" will use the sampledescription_index in the Track
Fragment Header to identify which of the sample entries in the 'stsd' box is
applicable to them."

So the 'stsd' box in the moov needs to have multiple entries, while in this
sample it has only one.

Nonetheless I don't think we handle multi-stsd entries just yet. Fixing the
sample is just the first step.
