As a company that specializes in the manufacture and sale of H.264/MPEG-2 video encoders and decoders we often find ourself having to offer technical support to our customers. In most cases the first thing we do is ask the customer to confirm that their setup works with VLC, because if it works with VLC then their issue is most likely not IP networking related. It would not be an exaggeration to say that 99% of all support questions are in fact related to incorrect networking setup.
For those not familiar with VLC (VideoLan), it is a free multimedia player supporting most file and streaming media formats. VLC is widely used by consumers and professionals alike.
It is therefore not surprising that the most common support question that we get asked is how to setup VLC in order to receive multicast or unicast streams. Hopefully the instructions below can help make this process clearer.
In a unicast configuration the encoder or the IPTV Gateway/Server is sending a UDP stream directly to the computer that is running the VLC.
VLC needs to be configured to lisiten for incoming streams on a specific port.
The above assumes that VLC on your computer is listening on an incoming port 5000 for UDP streams. Please make sure that your encoder/gateway is sending to this port and that all proper firewall rules are in place.
Multicast is used for one-to-many broadcast. In a multicast configuration the Encoder/Gateway sends the UDP stream to a multicast group, such as: 18.104.22.168. VLC then connects to this group on a specified port and plays the stream(s).
The above assumes that there is a multicast stream on a multicast group with ip address of 22.214.171.124 on port 5000.
Please note that for this to work the local network must be capable of supporting multicast.
