In the Publisher field, select Adobe Flash Dynamic Streaming. Note: Because the Niagara 4100 is a single-channel encoder, you can only connect and stream one audio and video source at any given time. However, you can encode the same audio and video at multiple data rates and multiple formats to provide the best user experience for different viewing audiences. 2. The bandwidth is cumulative so you must be careful not to exceed your network capability. If this field is blank, click the default folder link to automatically populate the field. See Exporting captured video files for instructions on saving video files to a USB device. ViewCast strongly recommends you do not alter the default directory setting unless you fully understand the risk of saving your files to a directory not located on drive D. If you save your files to another drive on the Niagara 4100, the system could delete the files when you use the Restore to Niagara 4100 Factory Defaults feature. ViewCast 55 Advanced Operations Only drive D on the Niagara 4100 has available storage to save your files. Check drive properties for available free space to determine your storage capacity. Use drives C, E, and F strictly for Niagara 4100 operational programs. Any modifications to these drives can permanently damage your system and void your warranty. A better practice would be to use a Flash Media server to save a file or to save it to a remote drive. If you inadvertantly fill all available space, you risk losing your stream during a streaming event. Note: The RTMP Address that displays at the bottom of the window is the Host Address, FMS Address.
