ffmpeg | branch: master | Stefano Sabatini <stefasab at gmail.com> | Sat Sep  8 01:18:09 2012 +0200| [eab438eabbefb44b35d2db05f233509bec0c3502] | committer: Stefano Sabatini

lavu/samplefmt: fix/clarify documentation for av_samples_fill_arrays()

In particular, avoid improper use of the term "channels" in place of
"planes", and fix erroneous documentation for the linesize parameter.
