[mythtv-users] Commercial detection and PVR-250?

[Jason S]

Chris,

>From what I understand, your code generates a file
tracking start/stop frames of commercials. This file
is used by the player to determine what scenes to
skip. (Sound right?)

Do you have a method to delete these frames completely
from the recordings? (I'm assuming that it does such a
wonderful job that I could trust it to do so!) For
example, instead of the marking scenes, it could cut
the frames in question. (Similar to tools such as
GOPchop (http://outflux.net/unix/software/GOPchop/). 

Seems like this would be a killer feature for everyone
out there looking to archive movies/recordings or play
back in something other then Myth. Plus it will save
some substantial space (it seems most shows are like
40% commercials these days!). 

Is this supported now? And if not, I'm assuming it's
because it's hard in some way... what would be
required to add this feature? From what I know you
shouldn't have to reencode the video stream, just cut
the appropriate frames and copy into a new file. If
re-encoding IS required I could see why it's an
uncommon feature. It could still be done in the Myth
encoder though, since you could just cut the raw
captured frames out of the buffer before encoding
them.

It's a critical feature for a PVR in my book (although
basically none do it that I know of!), I don't want to
have to go through files and cut out commercials by
hand every time before storing plus it would seriously
save space. Thoughts?
