ffmpeg | branch: master | Justin Ruggles <justin.ruggles at gmail.com> | Sun Oct  2 12:03:22 2011 -0400| [e32dfdaa8dbe77ffd47e8a66261584ad4ed5931c] | committer: Justin Ruggles

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.
