[FFmpeg-cvslog] r22983 - trunk/ffprobe.c

[stefano]

Author: stefano
Date: Wed Apr 28 01:22:27 2010
New Revision: 22983

Log:
Make ffprobe show sample_aspect_ratio and display_aspect_ratio only if
sample_aspect_ratio is known.

Avoid to show bogus values, which may confuse both the human and the
machine reader.

Based on a patch by Robert Kr?ger $(echo lsvfhfs at tjhobm7.ef | tr "b-za" "a-z").
