thanks for your response and apologies for the overdose of detail in
my original post. On the ffmpeg forum if you don't give full details
with console output you get told off...
"[f=flv]" is not working no matter where I put it in the command. It
'Unable to find a suitable output format for 'f=flv'
f=flv: Invalid argument'
'Unable to find a suitable output format for
could you please specify where this should go in the command and what
the correct syntax should be? Thanks again.
