Video encoder commands

These are the commands related to the built in video encoder in the ATEM Mini series of video switchers. This controls both the live stream and stream recorder component.

Live streaming

class pyatem.command.StreamingServiceSetCommand(name=None, url=None, key=None, bitrate_min=None, bitrate_max=None)

Implementation of the CRSS command. This sets the parameters for the live stream output. It is equivalent to adjusting parameters in the Live Stream settings of the Output menu of the UI Switcher panel.

Offset	Size	Type	Description
0	1	u8	Mask
1	64	str	Service name
65	512	str	Url
577	512	str	Streaming key
1089	3	?	padding bytes
1092	4	u32	Minimum bitrate (Bps)
1096	4	u32	Maximum bitrate (Bps)

Bit	Mask value
0	Service name
1	Url
2	Key
3	Min/Max bitrate

__init__(name=None, url=None, key=None, bitrate_min=None, bitrate_max=None)

Parameters:

• name – New streaming service name

• url – RTMP url

• key – Stream key

• bitrate_min – Minimum bitrate

• bitrate_max – Maximum bitrate

class pyatem.command.StreamingStatusSetCommand(streaming)

Implementation of the StrR command. This starts and stops the live stream. It is equivalent to pressing ON AIR in the Live Stream settings of the Output menu of the UI Switcher panel.

Offset	Size	Type	Description
0	1	bool	Stream enable
1	3	?	unknown

__init__(streaming)

Parameters:

streaming – True starts streaming; False stops

Recording

class pyatem.command.RecordingSettingsSetCommand(filename=None, disk1=None, disk2=None, record_in_camera=None)

Implementation of the CRMS command. This sets the parameters for the stream recorder. It is equivalent to adjusting parameters in the Record settings of the Output menu of the UI Switcher panel.

Offset	Size	Type	Description
0	1	u8	Mask
1	128	str	Filename
132	4	u32	Disk 1 id
136	4	i32	Disk 2 id
140	1	bool	Record in all cameras

__init__(filename=None, disk1=None, disk2=None, record_in_camera=None)

Parameters:

• filename – Filename for recording

• disk1 – ID for disk 1

• disk2 – ID for disk 2

• record_in_camera – Trigger recording on attached cameras

class pyatem.command.RecorderStatusCommand(recording)

Implementation of the RcTM command. This starts and stops the stream recorder. It is equivalent to pressing REC in the Record area of the Output menu of the UI Switcher panel.

Offset	Size	Type	Description
0	1	bool	Recording state
1	3	?	unknown

__init__(recording)

Parameters:

recording – Whether the hardware should be recording
