[Live-devel] Trick play with scrambled content

[Ross Finlayson]

'Trick play' on Transport Streams works by extracting video I-frames 
from the data, and streaming those only.  To do this, the indexing 
mechanism has to first parse the MPEG video data within the Transport 
Stream, to figure out where the data for each I-frame begins and ends.

Therefore, if the Transport Stream data is encrypted in such a way to 
make video I-frames unparseable, then you won't be able to do 'trick 
play' operations on it.  Sorry.
