I am downloading the *same* content using the command above but from 3 different
locations.
Sometimes there are disturbances in the feed from the main location and then I
want to clip up until the disturbance and paste in the continuation from another
of the sites.
This mostly works fine; always for video but sometimes not for audio.
Then the audio gets totally wrecked, like about 30 seconds or so off sync
following the clip paste point....
Can I modify the above command to ensure that audio gets a specific format like
the video argument does?
( -vf scale=w=-4:h=480 -c:v libx264 -preset fast -crf 26 )
During the actual download there is time to do these things since it is
happening in real time...
