Most if not all IPCAM run Linux, the trick part is its codec libraries that is tied to some old kernel using some strange toolchains, that can be improved with vendor's help over time.
In the past TI owns the IPCAM chip market, now it's Huawei, whose chip (hisilicon) occupies about 80+% IPCAM on the market nowadays and TI is getting out of this game. The project may only need support one or two chip vendors.
