Playlist based on codec

[hsbrown2]

All my video files are .mkv, but a few of them have the video using the VC-1 codec inside the container.

I have a few Android TVs with Kodi and/or the Mezzmo app, and VC-1 doesn't play on these. They don't appear to transcode either, presumably due to the container being supported, just not the codec inside.

I tried to puzzle out creating a smart playlist that contains only those files which do not use the VC-1 codec, but I cannot find the codec as a choice of property for the playlist.

Short of remuxing the video into H.264 or something, does anyone have a sneaky way to just not serve these to the devices in question?

TIA
