Comment (by Danny Weijermans):
thanks for your relevant link!
yes, but I'm not using a 'lossy' audio fileformat.
it's a 'firm' wav file, I have put an very short wav file (s.wav) example
as an attachment.
my command line (which works on longer wav files) for example:
ffmpeg -i /Users/disjt/Desktop/s.wav -filter_complex
"showwavespic=s=640x120" -frames:v 1 output.png
if /Users/disjt/Desktop/s.wav points to a longer wav file it's working
perfectly.
if it's a shorter than 200msec it's not working..
