I am curently using the Recording Auto Transcode 1080p (.mp4) setting. I want to see how well this will work with the NextPVR Roku app as I have trouble with OTA signal quality at times and I am hoping this may help.

Of course this means I have no PostProcessing script running and therfore I can't run Comskip automatically. Is there any way I can use both the Recording Auto Transcode setting and run a PostProcessing scriopt (with Comskip)?

I assume the answer is no. So, the next question is, are there any other ways to use NextPVR to run Comskip?

Thanks.

It’s not currently possible to do that. If you’re using a post processing script, you’d have to just do the mp4 conversion in the script. Ultimately the default conversion stuff is just running a ffmpeg command to do the conversion so pretty easy for you to replicate.

Actually wasn’t there a post conversion script? You might be able to run comskip in there.

You added PostVODProcessing but I don't think there is anything for automated transcoding. I thought the design was for PostProcessing to run before the automated transcode begin. A ts comskip file should work with a transcoded file since the skips are based on time not a file position.

If you've got a PostProcessing script, it assumes you're going to do any conversions and other processing yourself, and doesn't run the simple built in transcoder.

If you've got a custom script, it's pretty painless to also add the steps to do the same type of transcoding.

I'm currently experimenting with Auto Transcode, then I found this thread which tells me that postprocess.bat disables the auto-transcode.  I currently do transcode in my .bat file but I leave the .ts in place because I want to preserve the playback functionality in the web-client and Kodi.  I figure that if the .ts isn't where the .xml tells us, then things will break.  I figured that the auto-transcode would update the .xml to replace the .ts with .mp4(or whatever), so I was hoping that auto-transcode would run AFTER the postprocess.bat.
Given that this isn't the case, are there any suggestions for a quick and easy way to update the .xml so it points to the transcoded file rather than the original recording?

You can use:

nscripthelper -rename <oldtsfilename> <newfilename>

and it'll update the data base to point to the new file.

I've just to run D:\Program Files\NextPVR>NScriptHelper.exe -Pending and it failed.  I got:
[1] Unable to login

Just found the page in the Wiki on how to use it...
Yep - working, all good.

I have discovered though that I don't really need to touch the .xml as Kodi and the UI Client aren't fussy - if the .ts isn't there it will play the .mp4 with the same filename in the same folder.

If you use auto-transcode the mp4 file created will play in the browser without transcoding or remuxing.  The primary downlside to this is losing AC-3 audio plus the one size fits all transcoding isn't at all optimized so the ts file might be better quality. I say might because the mp4 remux does smooth out some ts file errors.

The only thing that I know uses the xml file is NextTool and I specifically ignore the internal filename.
