Overlapping recording on same channel caused performance issues in recording

[FordGT90Concept 97]

I can't really explain this one so have the facts...

 

1) NCIS is set to record 1.5 hours instead of 1 hour because it often got bumped by football games.  Nothing wrong here, it works as expected.

 

2) SEAL Team recorded in that 0.5 hour window for a total of 1 hour.  Combined, we're talking 2 hours of recordings with the 1.0-1.5 overlapping.

 

The problem...

 

#2, that 0.5 hours of overlap cuts in and out.  I have verified that the recording itself is damaged goods; however, the last 0.5 hours with no overlap works perfectly fine.

 

There's six tuners available so I suspect the bug is rooted in the stream duplication that Emby uses.  If it didn't duplicate but instead occupied another tuner, I think the bug wouldn't have happened but I obviously have no way to confirm that.

 

Unfortunately, no logs because this happened on the 27th and my logs only go back to the 29th (why not keep more logs, say, a month or at least a week?).  Should be easy enough to reproduce with an HDHomeRun though...

 

 

 

Edit: Is this an HDD performance problem?  If yes, might I recommend recording to the same drive Emby is on (SSD) then copying the finished stream to the destination (HDD)?  I imagine reading/writing could cause a fair amount of thrashing.

Do you record-transcode or leave as native .ts?

It transcodes in the HDHomeRun EXTEND (MPEG2 -> h264).  Should be just copying the stream to the server HDD

Hi @@FordGT90Concept, if this is an HDD performance problem then what you can do is configure your transcoding temp folder because that's where the live tv stream is held. from there it gets copied to your recording folder.

Transcoding-temp is already on C: so...that's not it.
