RealAudio 28.8 does not need or use sub_packet_size for its demuxing and this field is therefore commonly set to zero. But since 18ca491b the Real Audio specific demuxing is no longer applied if sub_packet_size is zero because the codepath for cook and ATRAC3 divide by it; this made these files undecodable. Furthermore, since 569d18aa (merged in 2c8d876d) sub_packet_size being zero is used as an indicator for invalid data, so that a file containing such a track was completely skipped. This commit fixes this by not checking sub_packet_size for RealAudio 28.8 at all. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
