Description
Video Resolution
Select Same as Input, 720, or 480 to set the streamed video resolution.
Video Bitrate
Use this to set the video bitrate, in Mbps. Maximum bitrates are 30
Mbps over WiFi, and up to 50 Mbps over Ethernet, depending on the
video resolution.
Video Frame Rate
Frame rate can be set to any value up to the source frame rate. Set this
to zero to match the input frame rate.
Coding Mode
Select Frame coding, Random Intra-refresh, or continuous intra-refresh.
Frame coding is necessary for MPEG-TS, while random intra-refresh gives
the best encoding performance at a given bitrate.
Intra Count/GOP size
When using intra-refresh modes, this specifies the amount of I-frame
segments. In Frame coding mode, GOP size specifies the number of
frames between I-frames.
Audio PCM Compression
Select None, aLaw, or uLaw.
None: no PCM linear compression is applied. 768kbps for one channel
audio, and 1,536kbps for stereo audio.
aLaw: European standard of G.711 compression. 384kbps for one
channel audio, and 768kbps for stereo audio.
uLaw: North American standard of G.711 compression. 384kbps for one
