Closed captioning in NPVR

[Joram]

At the risk of proliferating topics, I have a question about setting CC in NextPVR. (Mods: If there's an existing topic where this question would go better, please do move it there, thank you.)

There are three ways to try to enable or disable closed captioning in the NPVR UI client:

1. Mouse: Right-click on the NextPVR.exe UI window, then select Subtitle Stream from the context menu, and then select Closed Captions
   
2. Media Center Remote: Press the More Info button, then the Down arrow button to highlight the controls at the bottom of the overlay, then the Left arrow button to reach the hamburger menu, next click the OK button, and finally select Change Subtitle Stream
   
3. Keyboard: Press Ctrl-X to display the Select Subtitle Stream menu
   

On my main test PC, however, none of these is managing to actually set closed captioning: the subtitles never start appearing onscreen, and the next time I bring up the CC selection menu, "Disabled" shows as the current setting. I figure I must be missing a step or a setting somewhere.

@mvallevand has suggested using yauiclient.exe instead if CC is important to us and I may ultimately do that, but I'm curious as to what if anything can be done for this on NextPVR.exe. Maybe modifying some line(s) in config.xml?

If you want to supply a sample recording that should have captions, I'm happy to take a look.

@sub, thank you kindly for the offer. I made a 46-second recording but it already reached some 55MB in size, so no doubt it's too large to work as an attachment to this post. Therefore I'm sending you the recording via a file transfer service, with the link sent via PM.

Thanks for the file. I haven't looked at it yet, but will try to take a look tomorrow.

In the mean time, can you try activating closed captions using one of the mechanisms, then post your logs? There is one thing I need to check in there.

@sub, here's a log .ZIP file where I tried, in turn, each of the three methods for enabling CC. First with the mouse (actually, laptop touchpad), then remote, and then keyboard with Ctrl-X.

(Depending on how far back the logs go, you may incidentally come across an instance or more of where NextPVR.exe closed itself spontaneously, but that's a topic for another thread.)

Thanks very much.

Could I get your sample too please.

On its way.

Incidentally, and in case this helps: I tried playing the sample video on both NextPVR.exe and yauiclient on my other PC. (Transferred via sneakernet.) There, NPVR offers the same menu options for enabling CC, but again nothing actually happens. However, when I tried enabling CC on yauiclient, then (unlike as in NextPVR.exe) navigating to the Select Subtitle Stream menu showed only a single option ("Disabled"), and hitting Ctlr-X briefly showed a text overlay in the upper left corner that said, "Subtitles Track: no".

Is there closed captions on that channel? I've tried playing your recording in a few players, and haven't been able to get any of them showing closed captions.

Also, is the recording file you're trying to play the original, raw .ts file as captured directly by NextPVR from a digital source? i.e. you haven't converted it, remuxed it, etc.

Got it but is this an HDPVR recording it is h264 which is rare OTA in the US? If so they don't have CC's
