Flag poor quality recordings?

[boringgit]

I really don't imagine this is possible without directly driving the tuner....

However, in case I am wrong..

I set series recordings and then don't watch them for months. When I eventually come to watch them I sometimes find that for whatever reason the DVB signal had broken up enough in a recording to make it not worth watching.

At the time of the initial recording the episode which recorded badly was likely available a few days later, but a few months later it is long gone.

Does NPVR receive enough info about the quality of the DVB signal to understand that a recording may be rubbish? If so could it mark that episode for re-recording?

I should mention - this is more of an "I wonder" suggestion than "I would love if you could" because if I really cared I would have watched 6 months ago when it was aired  

Cheers!

Unfortunately NextPVR usually wouldn't be aware of this. I have this information available for some tuners, but not all, and the situation could easily vary throughout the recording, so it'd need to be monitoring continously. It would quickly become a complicated problem to try to implement well, but I don't think there is enough demand for this type of feature to justify the effort.

Gotcha.

It certainly isn't important

I have some scripts that can analyse the file post recording. One of them returns the number of continuity errors / transport errors, which is usually a good indication that something is wrong (ideally both would be zero).

These are in Python, so you could easily set a threshold above which the recording quality is considered poor. You could then act on that somehow. I wouldn't know how myself, but my guess is that there's probably already an API that would allow you to reschedule the recording via NextPVR? If it's a web API it should be really easy from Python.

Let me know if you'd like to explore that.

I don't know if there is an "easy" way to automatically try to reschedule.

However, you could use a variation of this script section that I use in my PostEPGUpdate to set a colored dot to flag these "bad" recordings in the recordings list. (Presuming you use a client that shows the dots like NextPVR.exe, knewc, Roku, nlite.)

This uses a sqlite3.exe in my scripts folder. You'd probably run it in the PostProcessing script so the OID for the recording would be the 3rd parameter. And you would replace the "recurrence_oid=128 and status=0" in the where clause.

Code:

REM Set Red & Yellow dots for recordings set by the S01E01 rule
"C:\Users\Public\NPVR-data\scripts\sqlite3.exe" "..\npvr.db3" "update scheduled_recording set red='Y', yellow='Y' where recurrence_oid=128 and status=0 and red is null and yellow is null" >..\logs\postupdateepg.log

Thanks a lot for the offer

If I ever get around to opening any of those free Udemy and Kindle "Learn Python in 7 days" and similar courses I will certainly give you a shout back, but for the time being It's all gibberish to me
