AVC max gop length?

[alky]

just curious:
anyone know how much the maximum gop length in the avs specs is?

There is no maximum, and in fact some streaming encoders put the entire stream in one GOP and use SEIs instead to mark seek-points.

There is no maximum, and in fact some streaming encoders put the entire stream in one GOP and use "access unit delimiters" instead to mark seek-points.

You meant "recovery point sei" instead of "access unit delimiter" (AUD), don't you ?

An access unit is composed of all the nal units associated to a single picture (field or frame). And it's delimited by AUDs which can appear optionally with every picture. In Transport Stream (TS), AUDs are mandatory.

Anyway, we're getting off topic :)
