Try using Web Video Caster (WVC). You install the WVC receiver channel on your Roku and then install the WVC app on your phone. (available in Play/Apple app store)
There is both a free and one-time $3 or $4 purchase option. The paid option gives a few more features but the free works perfectly fine. (an occasional ad on your mobile device, but not on the TV).
WVC is also currently working on/beta-testing a laptop/desktop version which works great.
The WVC receiver for Roku can be found in the Roku Channel Store. Not sure where you are located so don't want to send you a wrong link. Either search for it from your device in Streaming Channels (search "Web Video Caster") or go to the online Roku Channel Store and install it from there.
