LiveShell X

5.12. Difference in configurable items for each channel

LiveShell X has four video stream channels (#0 to #3). The roles of each channel are as follows.

  • #0～2・・・Channels used for live streaming or recording.
  • #3 ・・・Channel used for preview before live streaming or recording.

Differences per channel

Channel #0 can not be changed, it is fixed to the same as input resolution, the frame rate can be set at up to 60 fps.
To change output resolution, change the resolution of the input or change settings in the LiveShell X device menu or Dashboard to use channel #1 or 2.

We recommend you to use channel #1 or  2 when live streaming or recording at a frame rate of 30 fps or less.

About microSD card recording

To use LiveShell X’s recording function, a microSD card is required.

Although we do not recommend microSD cards from a specific manufacturer or brand, we recommend that SD cards that meet the following SD Association standards –

  • UHS Speed Class 1
  • Speed class 10

Please refer here for more information about Speed Class – https://www.sdcard.org/developers/overview/speed_class/

Due to the wide variety of SD cards available we cannot guarantee compatability with every card, if you encounter recording issues please first try a different SD card.

LiveShell X supports microSD cards formatted in exFAT and FAT32 format.

LiveShell X limitations for streaming and recording

LiveShell X restricts streaming and recording as follows.

  • Only one 1080p60 stream or recording (preview is possible)
  • Total streaming, recording and preview must be 150 Mpx/s or less (up to 3 simultaneous streams or recording at less than 1080p30)

Note that 1080p60 is 125 Mpx/s, 1080p30 is 62.2 Mpx/s, and 720p30 is 27.7 Mpx/s.

※ Recording will be treated as one stream
※ Maximum number of viewers in RTSP server mode is 5 clients (depending on bit rate, network quality, etc.)

Channel #0 resolution restrictions

The output resolution of channel #0 can not be changed by Dashboard or device settings, the output resolution will always be the same as the input resolution.

This restriction is in place due to channel #0 can be set up to 60 fps.

To change the output resolution of channel #0, change the resolution on the input device.

ub250_vertical_resolution

As mentioned above, in custom settings on Dashboard, channel #0 Vertical resolution will be grayed out at “1080px”. However this does not mean the resolution is currently 1080p if the input device is not set to 1080p resolution.

Using channel #3 (preview channel)

Channel #3 is used as a preview channel to check the video before streaming.

To watch preview video, please access “MONITOR URL” with an RTSP compatible player.

Note

  • If a class D address is specified, it becomes multicast. Please use 239.0.0.0 ~ 239.255.255.255. The default address is as follows.
    • #0: 239.11.250.0
    • #1: 239.11.250.1
    • #2: 239.11.250.2
  • The default port number is “1234”.
  • TTL should be larger than the number of routers through which the multicast packet passes.
    (When distributing to a local network, TTL should normally be set to “1”.)
  • When viewing multicast video in VLC, please add “@” before the IP address in the URL.
    Ex: udp://@239.11.250.0:1234
