From: Aman Gupta <a...@tmm1.net>
Currently only flv and asf decoders attempt to use pb->read_seek,
by calling avio_read_seek() expliclity.
This change allows avformat users to specify a custom AVIOContext
with a read_seek callback, and have it be used with any format
whenever av_seek_frame() is invoked.
