Subject: shn: do not allow seeking in the raw shn demuxer.
X-Git-Tag: android-x86-4.4-r1~8529^2~5124
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=e32dfdaa8dbe77ffd47e8a66261584ad4ed5931c;p=android-x86%2Fexternal-ffmpeg.git

shn: do not allow seeking in the raw shn demuxer.

The demuxer does not read the seektable, a parser is not possible without a
full decode, and no shorten decoder can handle random seeking because it needs
side info from the seektable.
