Once your device is configured, you should be able to simply click the Cast button in Chromium to Cast your current tab.VLC is one of the most useful video players on Windows & Android not only for its quality but it also provides lots of features.One of the most useful features among them is Stream VLC video directly on your Chromecast. If you have not yet set up your ChromeCast device, follow the instructions that come with the device to set it up. Note that an app/extension called ChromeCast is available, but this is not what you want. Install the Google Cast browser extension in either Chromium or Chrome. Iptables -I INPUT -p udp -m udp -dport 32768:61000 -j ACCEPTĪfter the ChromeCast device has been discovered (each time the browser starts), the browser will control it using TCP (HTTP) connections to port 8008, which should not require any special iptables rules. The ephemeral port range for the initial multicast packet should be 32768-61000 (Verify with cat /proc/sys/net/ipv4/ip_local_port_range), so the following rule should work (note it inserts at the top of the input rules): Therefore, you will need to add a rule to accept UDP packets on all ephemeral ports. In addition, the iptables -A INPUT -p udp -sport 1900 -j ACCEPT rule typically used for UPnP/SSDP will not work since the replies from the ChromeCast device do not come from port 1900. The typical iptables -A INPUT -m state -state ESTABLISHED,RELATED -j ACCEPT rule WILL NOT match the response packet, as iptables does not currently have a conntrack helper that supports SSDP. Note that this is slightly different than most other UPnP devices, which will usually respond with a unicast UDP packet from port 1900 instead of an ephemeral port. The ChromeCast device will respond with a unicast UDP packet from the ChromeCast device's IP and another ephemeral port to the source IP/port of the multicast packet.

The browser will send a multicast UDP packet from the local IP and an ephemeral (random) port to 239.255.255.250 port 1900.

Make sure iptables is configured to allow the UPnP/SSDP traffic used by the Google Cast browser extension to discover the ChromeCast device.

The 'chromium-browser' package in Ubuntu 13.04 works fine. Earlier versions will get a 'This application is not supported on this computer. Make sure you are running either Chromium or Chrome version 28 or higher. The documentation from Google indicates that the Google Cast extension is not supported in Linux, but it actually does work.
