This is a sort-of complicated issue. I am not sure where the issue is, but I will try to lay it out for you and give you a couple logs as well.
I am running Emby Server 4.2.1 on Ubuntu 18.04.3 on the following computer:
ASUS M Series M51AC
Core i7 4770 3.4 GHz
RAM 16 GB
HDD 1 TB
BIOS Version: 0901
Command: lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation GF119 [GeForce GT 620 OEM] (rev a1)
- the NAS couldn't handle recording the TV show while it was playing an earlier portion of the TV show
- Emby can't handle both recording and playback of the same show at the same time
- My computer hardware can't handle both
- Something else entirely
I do have a 1 TB hard drive in the ASUS computer itself. I could change the recording path to that drive and then make a cron job that moves the files about an hour after they are recorded to the NAS.
I do not know if this could help the problem?
I am attaching the log that I think the problem would be in. Please let me know if it isn't and I can give you other ones as well.
