[detectads] Automatically bookmark ad breaks

Also worth a mention that you can run DetectAds automatically following Decryption by going to Settings for detectads package.

Detectads requires the file to be decrypted first and symptoms that you see are common if the file has not yet been decrypted,

It would be helpful if it checked for the Decrypt flag and gave a more meaningful message,

Do you have autodecrypt specified for the folder? Otherwise you will need to run decrypt manually first

Thanks. You were right, I got confused over what was decrypted and what wasn't.
 
For the first time that I am aware of DetectAds failed to spot two ad breaks in this evenings Celebrity Chase program
Code:

15/11/2014 21:00 -   ad break found (2585 - 2656)
15/11/2014 21:02 -   ad break found (3158 - 3257)
15/11/2014 21:02 - done...processed in 725.717s - 3 ad breaks bookmarked
15/11/2014 21:02 - Removing item 244 (/media/My Video/The Chase_ Celebrity Special_20141115_1920.ts) from the queue
The missed breaks were approx 18 and 29 minutes into the program

I reran the analysis manually and silences were detected during the missed ad breaks but obviously not sufficient to be recognized as an ad break

if I could suggest a 'feature' - how about taking 5 seconds off the bookmark position at the end of ads (so bookmarks 3,5,7,9,etc.) then you'd know if any of the prog was missed due to a miscalculation.
[not sure if this is possible]
 
This seems to be working really well over all.

I would suggest that since me and others find that the selection needs inverting and we can not be sure which way around is best. A way to tell is to keep the larger bits and cut the smaller bits.
I don't think there is a channel with more ads than show....but who knows.

I would like to process a massive folder of a few hundred recordings, then invert and crop. Is there a way to automat this? Sorry if this has been mentioned and I've missed something.

Thanks again, great package.:)

Has there been any further development of this excellent package? In particular:
  1. Option of automatically running Nicesplice to cut out the ads that have been found
  2. Bypassing DetectAds on non-commercial channels
  3. Tweaking detection options - I have found some episodes of The Chase have short ad breaks that aren't recognized which means when I press the skip button I suddenly skip a long way through the program
