Streaming local media from Mac to Chromecast
It is seamless to stream media playback with in chrome browser tab, but no straight forward easy way to stream local media content to Chromecast. The experimental desktop sharing from the drop down in Chromecast extension have issues with audio. There are plenty of solutions discussed here.
But one easy solutions I found it working is using Videostream. Install it from here. Though it is a browser extension it doesn’t appear on browser. Launch it from Launchpad, it opens up a browser tab. Select the file and run. Done :)
