Test sample is made from the sample in Bug-Id: videolan/7411

The idct implementation cannot be changed after the quantization matrices
are read since it use a different permutaion.

Bug-Id: videolan/7411

Due to what looks like an off-by-one error 60 * 12 * 1001 / 12 * 1001
is not tested as standard frame rate in avformat_find_stream_info().

Makes it easier to recreate an AVCodecContext for ATRAC3+ decoding,
which is needed in multimedia frameworks, as well as in general cases
where demuxing and decoding are separate entities.
