examples/transcode-audio: fix on input with multiple streams

Browse Source 
On input files with muliple streams the best audio streams gets transcoded. If
this stream happens to have an `index > 0` the transcoding crashes as no
associated output stream is available.

This commit fixes this by using the first (and only) output stream.
