Using any of our recommended encoding software or streaming hardware should likely automatically make your broadcasts mobile compatible. These recommended options all support H.264/AAC encoding for the live broadcasts and this is what is required for mobile compatibility.
Additionally, you will want to make sure that you are broadcasting at a bit rate that mobile networks can support. For example, if you are broadcasting an HD quality stream, we would recommend you also use the option to send a secondary stream at a lower bit rate for those devices and networks that cannot support the higher bit rate HD stream. See the Multi Bit Rate section of the Getting Started articles for more information.
