[. . . ] Only drive D on the Niagara GoStream SURF has available storage to save your files. This drive has approximately 105 GB of storage capacity. Use drives C, E, and F strictly for Niagara GoStream SURF operational programs. Any modifications to these drives can permanently damage your system and void your warranty. A better practice would be to use the streaming 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. 6. 64 Click the Container Type. ViewCast Niagara GoStream SURF User Guide Step 7. 11.

The Encoder Properties windows for editing a new encoder or an existing encoder are identical. You must configure the audio and video settings for each encoder type. Use the Video, Audio, Output, and H. 264 Settings tabs to edit the settings. Begin with configuring the video and audio settings, then the streaming properties. The streaming properties and advanced streaming settings are different for each type of encoder. From the Flash Encoder Properties window (Figure 66), you can set the encoder to start streaming automatically by clicking the Auto Start checkbox. You can also start the encoder from this window by clicking the Start Flash Encoder link in the top right corner of the window. [. . . ] The problem is that the extra bits taken by the B-frames are taken from the Pframes, which makes this variable a balancing act. This value is the quantizer scale offset between I-P-B-frames. The encoder normally encodes all 3 color planes (luma, U (chroma), V (chroma) ) at the same quantizer. The system adds this value to the quantizers for the U and V planes. [. . . ]
