back_ptr must point to a position within 16 bytes of a syncpoint
startcode. This syncpoint MUST be the closest syncpoint such that at
least one keyframe with a pts lower or equal to the original syncpoint's
global_key_pts for all streams lies between it and the current syncpoint.
back_ptr must point to a position up to 15 bytes before a syncpoint
startcode. Relative to position of current syncpoint. The syncpoint
pointed to MUST be the closest syncpoint such that at least one keyframe
with a pts lower or equal to the current syncpoint's global_key_pts for
all streams lies between it and the current syncpoint.
A stream where EOR is set is to be ignored for back_ptr.
