I've now done some further testing and found 2 things; first, I needed to
change +7 to +10 and second, I now see the conversion progress update only
every 40 seconds or so (it only seems to show every 10th update), so it is not
as clean a fix as I'd hoped for.
How hard would it be to add a command line parameter (or an additional
verbosity setting) to suppress the call to show_banner() in ffmpeg.c? I'd do
it myself but I really don't know what I'm doing. I'd be prepared to try it if
someone could give me some useful hints of what needed to be changed.
BTW, where can I find a definition of the settings for the -verbose option?
The web site documentation and the man page both say "-v number : Set the
logging verbosity level" without actually specifying what the acceptable range
for <number> is, how many levels there are or what each level presents...
