Properties

absentInputAudioBehavior → M2tsAbsentInputAudioBehavior?

When set to drop, output audio streams will be removed from the program if the selected input audio stream is removed from the input. This allows the output audio configuration to dynamically change based on input configuration. If this is set to encodeSilence, all output audio streams will output encoded silence when not connected to an active input stream.

final

arib → M2tsArib?

When set to enabled, uses ARIB-compliant field muxing and removes video descriptor.

final

aribCaptionsPid → String?

Packet Identifier (PID) for ARIB Captions in the transport stream. Can be entered as a decimal or hexadecimal value. Valid values are 32 (or 0x20)..8182 (or 0x1ff6).

final

aribCaptionsPidControl → M2tsAribCaptionsPidControl?

If set to auto, pid number used for ARIB Captions will be auto-selected from unused pids. If set to useConfigured, ARIB Captions will be on the configured pid number.

final

audioBufferModel → M2tsAudioBufferModel?

When set to dvb, uses DVB buffer model for Dolby Digital audio. When set to atsc, the ATSC model is used.

final

audioFramesPerPes → int?

The number of audio frames to insert for each PES packet.

final

audioPids → String?

Packet Identifier (PID) of the elementary audio stream(s) in the transport stream. Multiple values are accepted, and can be entered in ranges and/or by comma separation. Can be entered as decimal or hexadecimal values. Each PID specified must be in the range of 32 (or 0x20)..8182 (or 0x1ff6).

final

audioStreamType → M2tsAudioStreamType?

When set to atsc, uses stream type = 0x81 for AC3 and stream type = 0x87 for EAC3. When set to dvb, uses stream type = 0x06.

final

bitrate → int?

The output bitrate of the transport stream in bits per second. Setting to 0 lets the muxer automatically determine the appropriate bitrate.

final

bufferModel → M2tsBufferModel?

Controls the timing accuracy for output network traffic. Leave as MULTIPLEX to ensure accurate network packet timing. Or set to NONE, which might result in lower latency but will result in more variability in output network packet timing. This variability might cause interruptions, jitter, or bursty behavior in your playback or receiving devices.

final

ccDescriptor → M2tsCcDescriptor?

When set to enabled, generates captionServiceDescriptor in PMT.

final

dvbNitSettings → DvbNitSettings?

Inserts DVB Network Information Table (NIT) at the specified table repetition interval.

final

dvbSdtSettings → DvbSdtSettings?

Inserts DVB Service Description Table (SDT) at the specified table repetition interval.

final

dvbSubPids → String?

Packet Identifier (PID) for input source DVB Subtitle data to this output. Multiple values are accepted, and can be entered in ranges and/or by comma separation. Can be entered as decimal or hexadecimal values. Each PID specified must be in the range of 32 (or 0x20)..8182 (or 0x1ff6).

final

dvbTdtSettings → DvbTdtSettings?

Inserts DVB Time and Date Table (TDT) at the specified table repetition interval.

final

dvbTeletextPid → String?

Packet Identifier (PID) for input source DVB Teletext data to this output. Can be entered as a decimal or hexadecimal value. Valid values are 32 (or 0x20)..8182 (or 0x1ff6).

final

ebif → M2tsEbifControl?

If set to passthrough, passes any EBIF data from the input source to this output.

final

ebpAudioInterval → M2tsAudioInterval?

When videoAndFixedIntervals is selected, audio EBP markers will be added to partitions 3 and 4. The interval between these additional markers will be fixed, and will be slightly shorter than the video EBP marker interval. Only available when EBP Cablelabs segmentation markers are selected. Partitions 1 and 2 will always follow the video interval.

final

ebpLookaheadMs → int?

When set, enforces that Encoder Boundary Points do not come within the specified time interval of each other by looking ahead at input video. If another EBP is going to come in within the specified time interval, the current EBP is not emitted, and the segment is "stretched" to the next marker. The lookahead value does not add latency to the system. The Live Event must be configured elsewhere to create sufficient latency to make the lookahead accurate.

final

ebpPlacement → M2tsEbpPlacement?

Controls placement of EBP on Audio PIDs. If set to videoAndAudioPids, EBP markers will be placed on the video PID and all audio PIDs. If set to videoPid, EBP markers will be placed on only the video PID.

final

This field is unused and deprecated.

final

esRateInPes → M2tsEsRateInPes?

Include or exclude the ES Rate field in the PES header.

final

final

etvSignalPid → String?

Packet Identifier (PID) for input source ETV Signal data to this output. Can be entered as a decimal or hexadecimal value. Valid values are 32 (or 0x20)..8182 (or 0x1ff6).

final
