Add/Edit Stream

Add/Edit Stream

Screenshot

When you create a stream, you choose:

  • Profile — the profile that defines how the feed is encoded and sent to the Studio (codec, fps, resolution, bitrate, destination server, SRT parameters, etc.). See Streaming Setup for profile configuration.

  • Source — the input device or capture source for this stream (SDI, NDI, etc.).

  • Stream ID - you can also optionally set a Stream ID (or RTMP Key )

TIPS: You can use the same source for few streams. For example, capture the same SDI input several times and send it with different encoding parameters to different destinations — each stream can use its own Profile.

Advanced options

You can specify additional parameters that significantly expand functionality. For convenience, these parameters are shown as a tag cloud below the field.

Screenshot

Below is a description of these parameters.

channels

Select audio channels (counting starts at 1).

channels = 8,9,10,11

video_pid

Change the video PID. Default: 256.

video_pid = 222

audio_pid

Change the audio PID for the first stereo track. Default: 257. Each additional stereo track uses previous PID+1.

audio_pid = 223

external_audio

Use audio from an external source instead of the capture device.

external_audio = "PC Sounds (Loopback)"

NOTE: Audio device names are listed in the top menu under SysInfo (see here ).

ptz_udp

PTZ camera address for REMI control.

ptz_udp = 192.168.1.33:5678

NOTE: Turn on REMI Control in Streaming Setup for the selected profile.

ts_bitrate_kbs

Set a flat constant outgoing bitrate in Kbps. The stream will include TS-null packets to maintain the specified rate.

ts_bitrate_kbs = 10000

Example for a target bitrate of 10 Mbps.
