[FFmpeg-cvslog] Make detection of single-stream flv work again.

[Reimar Döffinger]

ffmpeg | branch: master | Reimar Döffinger <Reimar.Doeffinger at gmx.de> | Wed Dec  7 21:51:27 2011 +0100| [8b8a47f6fba938266e142367ab7f714af430503a] | committer: Reimar Döffinger

Make detection of single-stream flv work again.

It had become dead code when code was added to avoid
exporting audio and video codec id as metadata.
Untested due to lack of sample.
