Is this some newer format that the VBox device does not understand? After some probing and other Plex forum reading, I found GET / and POST /devices/discover which return XML from the VBox device:
When you get it set up, I’m curious if you can answer a question - can it transcode codecs in realtime before it sends to Plex? Or is that a feature for recordings stored on that device?
I will be sure to let you know. There’s a “Transcoding Profiles” page in the VBox settings. I don’t see any indication that it can or cannot be used with Plex DVR yet. I have a pretty weak server right now, so I’m hoping it can.
I followed through on those instructions already and also took a look through the user manual. I’ve had the box up for a couple months using the Android TV apps and live TV directly on the device. Finally bought a Plex pass today to try this out.
VBox Live TV version: 2.23
VBox Firmware: XTI_VT.2.66.31
They make a pretty strong claim that it’s supported (Apps | VBox Communications), so I’m a little frustrated. I’m waiting for my account to be approved on their forum (VBox TV Gateway Forum -Index page) to post there and see if they have anything to say.
I use a XTi - 4144 with Plex. I assumed the 4174 and 4144 were largely the same device but the 4174 has extra support for ATSC. Especially looking at your firmware version. Interesting if not though.
All I did was turn on the ‘Enable Plex’ setting under Streaming > IPTV in the VBOX advanced settings. Plex was then able to automatically find it when adding a new DVR in Plex. Annoyingly this setting is off by default.
Thanks for the response and clarification. I was trying to add it manually.
I had some challenges getting it discovered via SSDP (devices were in separate VLANs plus Plex was in a Docker bridge network that couldn’t send/receive UDP broadcasts outside its subnet). Obviously those are self induced, but being able to enter the address manually would have been beneficial and saved me a few hours in Wireshark.
At least one other person had similar issues, so I might open a feature request:
On the Vbox 4144 with firmware 2.68 . .
Unable to connect the device in Plex - Version 1.25.6.5577
Msg from the Vbox support team:
Please restart your plex server and the Vbox device (please note plex may take his time… for detecting the VBox device )
