This is an interesting feature. I tried several values for these
configuration variables as you suggested, but I couldn't get the chapter
marks to move from the fixed 15000 frame steps. It did take a little
longer, but not as long as you have warned:
chapters/interval=15000
chapters/minimum=1
chapters/threshold=5000

Hi! Francesco Fumanti wrote: However, I made a strange observation: the settings file contains wheel/incr_normal=1500 which I assume corresponds to one minute of a PAL movie. But if I use the right arrow key to jump forward, it jumps a little less than 1 minute, as the indicator with the milliseconds decreases (similar for the left arrow). Is this normal? Yes. In coarse mode, the position snaps to the nearest I frame. That allows faster navigation because you don't have to decode the whole GOP. Actually, this behaviour is configurable. If you travel less than wheel/threshold (default: 24) frames, the program switches to fine mode and positions accurately. You can change the threshold by editing the configuration file. By the way, why don't you simply use the frame number in the most right field (milliseconds) of the time indicator? In other words, you leave the indicators for hours, minutes, seconds the way it is; you replace the indicator that shows 1/1000 seconds with integer numbers that go from 0 to 24 for PAL movies, from 0 to 29 for NTSC movies,... generally, it would go from 0 to (fps - 1). I think it would be easier to understand at what picture of the current second the movie has been stopped. Well, it's a *time* display, isn't it?

I would suggest using several keys instead of one key for forward jump and one key for backward jump, coupled with modifiers to determine different jump distances. Of course, placing additional buttons for the jumps on the window would make it even more userfriendly. Concerning the settings file: it might be more easy to find it if it was at the root level of the user's home directory ( ~/.dvbcut ) instead of under .qt . Finally, what about adding a Help menu to dvbcut, even if that help menu only displays a simple text file with instructions about how to use dvbcut and a faq.

Cool! I had no idea. I think dvbcut really needs a simple Help menu for
this :)
Now, to really make it simple for finding commercials, it would be GREAT
if dvbcut could identify the black frames during indexing or a separate
scan. Then, the user can jump through them and fine-tune cut points. I am
a little confused about the difference from frame function and
... guess thats already answered...
yes, thanks, Francesco, for that.
auto-chapters function. Maybe these can already do what I suggest, but I
don't know how to use them properly.
Auto-Chapters sets a chapter mark every fixed number of frames or a fixed
number of chapters if chapters/interval is negative, which you can also
configure in the settings files.
Ok.
I also had in mind implementing a black frame detection for Auto cut
points,
but that was far too slow with the used imageprovider. Maybe it could be
implemented more effectively on the mpeg level during indexing somehow...
don't know... however, not every commercial begins with a black frame and not
every black frame starts a commercial.
Yes, I agree. That's why I was saying it should make a list and then the
user can flip through them to fine tune them. You can always add new
cutpoints, but having the black frames automatically will save huge
amounts of time.
BTW, If you want tho see how slow frame processing is or have a fast enough
CPU you could set chapters/tolerance0. That way inbetween the given numer of
frames around the normaly fixed chaptermarks from above the nearest scene
change (=sum of color distances chapters/threshold) is detected to find a

A black frame detection would work similar slow ...
Ok, I will try this on my Core 2 Duo 2100 and post the results.

Hello, There is another feature that I would welcome: It would be handy if it was possible to play the stream in different fast forward speeds (at least 16x and 32x) when searching for ads. This way the user would simply have to watch and press the stop button when an ad appears.
