packets, still depended on this code for proper packet duration and
timestamp generation.

96a7099f3e avcodec/av1_parse: take trailing bits into account when initializing the GetBitContext 
Also only initialize it in ff_av1_packet_split() and not ff_av1_extract_obu(),
same as h2645_parse, so GetBitContext specific failures may not affect the
latter.
