We have a very large install base using On Board Units with the imx7 Colibiri cores driving them. We have an urgent need to support WebRTC. We spent some time trying with the standard Toradex Linux Yocto (Colibri-imx-emmc 4.9.87-2.8.4+g3bb6e32 armv7l which includes Firefox v.52) and were not successful. Through the internet we found out that the next version of Firefox will support WebRTC. Does anyone know if this exists for the imx7? Other recommendation?
