JustStream is intended to wirelessly mirror your computer screen and stream videos to other devices. Luckily, the tool supports a wide array of target devices, including smart TV's and Chromecast.
The application runs unobtrusively from the Menu Bar, and you can make the desired adjustments from its icon there. Good news is that it can automatically scan the local network and detect any compatible device. Then, you can simply pick one of them from the list and start streaming the selected contents.
It is excellent that JustStream can transcode practically any video format. Likewise, it can process subtitles seamlessly, irrespective of the source format. Similarly, the user may choose to replace the original sound track with an external audio file. Unfortunately, it may take some time before the tool can start streaming.
Besides streaming, the application can also mirror your Mac's screen exactly as you see it on any other supported device. Luckily, it is not necessary to change the current screen resolution. However, you may experience certain lag.
In short, JustStream helps you expand your system's possibilities by allowing you to mirror your desktop as well as stream video contents on other devices. The product can be downloaded and installed from the Mac Store; however, in-app purchases may be required.
