Thanks Stephen - I'd read the docs on MythTV commercial detection
parameters and was dubious about it's reliability.
I'm sure someone has looked at using sound compression levels to detect
ads - but couldn't quickly find any references. I know the Japanese
video recorders reliably remove ads on the basis of shows/movies having
multiple languages and ads having none - but couldn't find any
references to software projects that do the same.
I'll have a look at what MythTV uses for video editing, I'd prefer to
use a frame based editor to avoid those fade transition relics. Avidemux
is great for simple frame based edits - and has the added advantage that
it also works natively with most video formats which save a lot of time
transcoding.
I found Comskip which seems fairly useful for marking ads, which I could
later feed the output of into ffmpeg (as another poster suggested) to
autochop the ads out.
Comskip requires WINE:-
