Printer (Brother/Epson) support for IoT VLAN

I have succeeded in getting a Brother HL-2135W laser printer working across VLANs.  I assume this solution will work for most if not all Brother network printers.  Subsequently, I've found that the same protocols are used by an Epson WF-3640 inkjet printer and the solution also works for that printer. I quickly worked around Windows printer discovery by entering the static IP address in to the printer Port configuration. But I had struggled to get the Brother Print Services (Android) plugin working.  The solution required some firewall rules and a utility to send broadcasts between VLANs.

Lossless conversion of MKV to MP4

Easy MKV to MP4 Recently I discovered that Davinci Resolve  (NLE and Color Grading software) is incapable of reading MKV ("Matroska" multimedia container) files.  MKV files are my go-to container format simply because of the convenience, given that there are utilities provided for muxing/demuxing and it supports any video or audio formats you want to use within the container. Unfortunately the Davinci Resolve media pool just ignores files with that extension.  Shame on them, I would have expected them to adopt open standards like Matroska.  For what it's worth it looks like other NLE software like Adobe Premiere Pro does not support it either.  I guess their justification is that they only need to support the formats that cameras record in. Anyway, given I was working with H.264 video and AAC audio, I knew I should be able to put multiplex into a MP4 (or even MOV) container to make it compatible with Davinci Resolve.
