Attempting to start media playback kills network connection

[tdsotm]

I followed the guide to install in TrueNAS Core. Jail instalation went fine, mount points look fine, media library loads as expected. But as soon as I hit play on the film I lose connection to both the jail and the host. Pinging to either the jail or the host result is mostly Request timed out, a few Destination host unreachable and a few correct responses. It doesn't matter if I assign DHCP or a static IP to the jail. If I don't start media playback everything works fine. Jellyfin logs do not throw errors. If I close the browser tab connectivity resumes in about 1 minute(or 2).

LE: This happens only AFTER I set up Intel HW encoding. If I don't transcode everything works, but defeats the point of me having wh acceleration. There is no log for transcodes after I enabled hw accel

[Thefrank]

It sounds like the jail is having an issue. are there any dmesg errors on the host about the jail when that happens?

[tdsotm]

I don't know how far back I should go, but here's the output of the dmesg: Just as a note, I was watching dmesg but when the connection is lost so was what my connection to the server.

does pciconf -lv list your device? Does it match the supported chipsets for the driver(s) installed in the jail? example from my system with video provided just by the server motherboard for console:

vgapci0@pci0:11:0:0:    class=0x030000 rev=0x00 hdr=0x00 vendor=0x102b device=0x0534 subvendor=0x1028 subdevice=0x0528
    vendor     = 'Matrox Electronics Systems Ltd.'
    device     = 'G200eR2'
    class      = display

[tdsotm]

It does:

I suspect you might be running into the same problem I had in #46.

Check your system uptime, the hardware acceleration might be causing a kernel panic which then causes your system to reboot. That would explain why it goes down immediately, doesn't save a log file and takes a minute or two to come back up.

In my case, the problem was that it would not work without a display connected. You could try either attaching a monitor or using a cheap dummy HDMI plug.

[Thefrank]

Your chipset falls here: https://en.wikipedia.org/wiki/Intel_Graphics_Technology#Skylake. Double check that you have the libva-intel-media-driver package installed. libva-intel-driver is for older chipsets

edit: also see @michaelburton comment above

[tdsotm]

@Thefrank The package is installed in the jail, as it was written in the instructions. @michaelburton - plugging in a monitor fixed the issue, thanks! It's a bit sad the my iGPU can't transcode hevc 10 being a 6400, but the error is now gone.
