NextPVR creates empty TS files

[motocrossmann]

NextPVR was working a week or so ago.   Since then, all recordings result in TS files that are tiny, like 5 megs.   Obviously VLC can't play it.   When I look at the NextPVR logs it looks like it is recording okay, but I'm not sure what is happening.   I do recall doing an apt-get upgrade, so maybe that broke something.

Code:

It looks like low signal quality, I'd check cables and the antenna. For me I can't view several stations once the leaves comes back in the spring.

That could be the case.   I occasionally have signal problems around here.   I'll try and move it to a better location and see if that takes care of it.    Tx!

I just noticed this at the top of the nrecord.log:

2020-06-02 15:49:47.900 [ERROR][1] Recording directory does not exist: /media/pi/f1d746a4-9a0c-4313-bb69-4fe202a0aa3b/RecordedTV/
2020-06-02 15:49:47.935 [ERROR][1] LiveTV directory does not exist: /media/pi/f1d746a4-9a0c-4313-bb69-4fe202a0aa3b/Buffer/

Those directories do exist and files are showing up in them, but seems odd that that shows up in the log?

[mvallevand]

I don't know because you didn't post your logs and I hate snippets. I suspect that is being logged before the drive is mounted and you need to add a delay in PreStartup.sh

[motocrossmann]

Appreciate the help Martin.  Here are the log files.  These were generated after a fresh reboot and a single recording was attempted.  I moved the system to a location in the house with a better signal and also resolved those errors mentioned above, but I still get mostly empty TS files.  (about 5mb)

[mvallevand]

Could you copy one of those 5MB files somewhere on the cloud and provide a link?

Martin

[motocrossmann]

Here is the TS file:

[mvallevand]

None of the audio or video streams are being included with the file. Checking again I see you are trying to record clear QAM. Is that really what you want to do?

Martin

[motocrossmann]

Yes, exactly. Odd that it was working at one point.
