I've been following a thread on the Comskip forums and it appears that there is a version of comskip available for donators to try out. It's still in beta stages but some have been noting good results with it. Note, however that of the reports i've read of people who have used it, the comskip processing of a typical 2 hour movie file can take up to 10 hours on a half decent machine to deal with. It's not very fast, but could be worth a shot for batch converting overnight.

Cool!

The only problem we could well run into is the AAC audio. This could post a real stumbling block..

Edit: ignore that last big - I just read the gb-pvr forums and it seems to work with AAC audio!

erik on GB-PVR forums: Thanks to those that provided some samples.
h.264 video and AAC or MPEG2 audio is working on files from NZ and Sweden

So going by that i'd be thinking aac should be working without too much trouble...

If it works well I'm sure there will be a lot of happy people!

With the quality of our H.264 broadcasts it should deliver near perfect results. It is a shame about the processing time but H.264 video is very complex. Time up upgrade to a quad core for your HTPC!

I've just sent the author a donation for access to the new release so will hopefully get a chance to play with it tonight.

Good stuff, i did the same a couple of weeks ago hoping that the 264 release was imminent, and here it is and i'm a happy boy. I haven't had time to play with it yet though. Hopefully by the weekend at this rate.

I wonder if the h.264 decoder will be selectable, I "think" that NVIDIA cards can decode more than 1 stream at a time

That will be interesting won't it. Might pay to have a bit of a chat about it on the Comskip forums with Erik about it.

It would be great if there was a CUDA version, then my 8500GT could do the work rather than my poor 5200.

I've tried it but get an initialisation error. I don't have the vc9.0 runtime files it seems and don't know how to get them (Erik didn't tell me). He should be embedding the necessary files I believe. If anyone has it running, and knows about the vc9.0 files, please elaborate.

I installed this last night and had a plsy with it. Unfortunately due to an EUE (End User Error) I selected a 3News recording as a test video - 3News has no watermarks during it so of course didn't work very well at all!

It took just on 3 hrs on my machine for a 1 hr recording which is something that can hopefully be improved upon. I'll test it on a shorter recording this evening with a watermark and ads in it and will hopefully get better results. With the quality of our H.264 recordings I would hope that comskip should have close to prefect watermark detection.

Any update on the success of Comskip's functionality of skipping adverts on FreeviewHD? If it works well, looks like I'll be spending some dollars.

It certainly works but needs a bit of tweaking for NZ - I found some NZ settings that I used to use but haven't had a chance to test it yet.

The main problem is the speed - roughly 3x real time to process a show which is not ideal.

Can anyone update on how this testing is going? I am specifically wondering:

- How would my 5200X2 go? Assuming I use batch processing, would get through a reasonable amount overnight?
- How good is the processing? Like what sort of success rate at finding ads
- Finally, is it stable? Does comskip crash, does it cause the computer to crash?

Cheers

I only played with this for a few recordings and flagged it due to the time requirements.

It is stable and works fine - it just takes a long time do process H.264 files. If you have a PC on 24/7 then it would obviously work fine at night but just takes a long time to process files.
