Alex Converse 4d2b9ece45 avformat/flvdec: Set need_context_update when setting the initial extradata 
Fixes ticket 6398.

Debugged with the help of James Almer and Hendrik Leppkes.

Alex ConverseandSean McGovern 504403ab28 aacsbr: Turnoff in the event of over read. 
Aliased compressed AAC bytes are almost certainly not meaningful SBR
data. In the wild this causes harsh artifacts switching HE-AAC streams
that don't have SBR headers aligned with segment boundaries.

Turning off SBR falls back to a default set of upsampling parameters
that can function as a sort of error concealment. This is consistent
with how the decoder handles other sorts of errors.

Alex Converse 1fce67d640 aac_latm: Align inband PCE to the start of the payload 
A strict reading of the spec seems to imply that it should be aligned to
the start of the element instance tag, but that would break all of the
samples with PCEs.

It seems like a well formed LATM stream should have its PCE in the ASC
rather than inband.
