Arbitrary user-supplied metadata that will be included in the asset details and related webhooks. Can be used to store your own ID for a video along with the asset. Max: 255 characters.
Specify what level (if any) of support for mp4 playback. In most cases you should use our default HLS-based streaming playback ({playback_id}.m3u8) which can automatically adjust to viewers' connection speeds, but an mp4 can be useful for some legacy devices or downloading for offline playback. See the Download your videos guide for more information.
Normalize the audio track loudness level. This parameter is only applicable to on-demand (not live) assets.
Specify what level (if any) of support for master access. Master access can be enabled temporarily for your asset to be downloaded. See the Download your videos guide for more information.

Configure the incoming live stream to include subtitles created with automatic speech recognition. Each Asset created from a live stream with generated_subtitles configured will automatically receive two text tracks. The first of these will have a text_source value of generated_live, and will be available with ready status as soon as the stream is live. The second text track will have a text_source value of generated_live_final and will contain subtitles with improved accuracy, timing, and formatting. However, generated_live_final tracks will not be available in ready status until the live stream ends. If an Asset has both generated_live and generated_live_final tracks that are ready, then only the generated_live_final track will be included during playback.

When live streaming software disconnects from Mux, either intentionally or due to a drop in the network, the Reconnect Window is the time in seconds that Mux should wait for the streaming software to reconnect before considering the live stream finished and completing the recorded asset. Max: 1800s (30 minutes).
Reduced and Low Latency streams with a Reconnect Window greater than zero will insert slate media into the recorded asset while waiting for the streaming software to reconnect or when there are brief interruptions in the live stream media. When using a Reconnect Window setting higher than 60 seconds with a Standard Latency stream, we highly recommend enabling slate with the use_slate_for_standard_latency option.
By default, Standard Latency live streams do not have slate media inserted while waiting for live streaming software to reconnect to Mux. Setting this to true enables slate insertion on a Standard Latency stream.
The URL of the image file that Mux should download and use as slate media during interruptions of the live stream media. This file will be downloaded each time a new recorded asset is created from the live stream. If this is not set, the default slate media will be used.

And "signed" (an additional access token is required to play the asset). If no playback_policy is set, the asset will have no playback IDs and will therefore not be playable. For simplicity, a single string name can be used in place of the array in the case of only one playback policy.
Arbitrary user-supplied metadata that will be included in the asset details and related webhooks. Can be used to store your own ID for a video along with the asset. Max: 255 characters.
Specify what level (if any) of support for mp4 playback. In most cases you should use our default HLS-based streaming playback ({playback_id}.m3u8) which can automatically adjust to viewers' connection speeds, but an mp4 can be useful for some legacy devices or downloading for offline playback. See the Download your videos guide for more information.
Normalize the audio track loudness level. This parameter is only applicable to on-demand (not live) assets.
Specify what level (if any) of support for master access. Master access can be enabled temporarily for your asset to be downloaded. See the Download your videos guide for more information.

Configure the incoming live stream to include subtitles created with automatic speech recognition. Each Asset created from a live stream with generated_subtitles configured will automatically receive two text tracks. The first of these will have a text_source value of generated_live, and will be available with ready status as soon as the stream is live. The second text track will have a text_source value of generated_live_final and will contain subtitles with improved accuracy, timing, and formatting. However, generated_live_final tracks will not be available in ready status until the live stream ends. If an Asset has both generated_live and generated_live_final tracks that are ready, then only the generated_live_final track will be included during playback.

When live streaming software disconnects from Mux, either intentionally or due to a drop in the network, the Reconnect Window is the time in seconds that Mux should wait for the streaming software to reconnect before considering the live stream finished and completing the recorded asset. Max: 1800s (30 minutes).
Reduced and Low Latency streams with a Reconnect Window greater than zero will insert slate media into the recorded asset while waiting for the streaming software to reconnect or when there are brief interruptions in the live stream media. When using a Reconnect Window setting higher than 60 seconds with a Standard Latency stream, we highly recommend enabling slate with the use_slate_for_standard_latency option.
By default, Standard Latency live streams do not have slate media inserted while waiting for live streaming software to reconnect to Mux. Setting this to true enables slate insertion on a Standard Latency stream.
The URL of the image file that Mux should download and use as slate media during interruptions of the live stream media. This file will be downloaded each time a new recorded asset is created from the live stream. If this is not set, the default slate media will be used.

The second text track will have a text_source value of generated_live_final and will contain subtitles with improved accuracy, timing, and formatting. However, generated_live_final tracks will not be available in ready status until the live stream ends. If an Asset has both generated_live and generated_live_final tracks that are ready, then only the generated_live_final track will be included during playback.

When live streaming software disconnects from Mux, either intentionally or due to a drop in the network, the Reconnect Window is the time in seconds that Mux should wait for the streaming software to reconnect before considering the live stream finished and completing the recorded asset. Max: 1800s (30 minutes).
Reduced and Low Latency streams with a Reconnect Window greater than zero will insert slate media into the recorded asset while waiting for the streaming software to reconnect or when there are brief interruptions in the live stream media. When using a Reconnect Window setting higher than 60 seconds with a Standard Latency stream, we highly recommend enabling slate with the use_slate_for_standard_latency option.
By default, Standard Latency live streams do not have slate media inserted while waiting for live streaming software to reconnect to Mux. Setting this to true enables slate insertion on a Standard Latency stream.
The URL of the image file that Mux should download and use as slate media during interruptions of the live stream media. This file will be downloaded each time a new recorded asset is created from the live stream. If this is not set, the default slate media will be used.

An array of playback policy names that you want applied to this asset and available through playback_ids. Options include: "public" (anyone with the playback URL can stream the asset). And "signed" (an additional access token is required to play the asset). If no playback_policy is set, the asset will have no playback IDs and will therefore not be playable. For simplicity, a single string name can be used in place of the array in the case of only one playback policy.
Arbitrary user-supplied metadata that will be included in the asset details and related webhooks. Can be used to store your own ID for a video along with the asset. Max: 255 characters.
Specify what level (if any) of support for mp4 playback. In most cases you should use our default HLS-based streaming playback ({playback_id}.m3u8) which can automatically adjust to viewers' connection speeds, but an mp4 can be useful for some legacy devices or downloading for offline playback. See the Download your videos guide for more information.
Normalize the audio track loudness level. This parameter is only applicable to on-demand (not live) assets.
Specify what level (if any) of support for master access. Master access can be enabled temporarily for your asset to be downloaded. See the Download your videos guide for more information.
Marks the asset as a test asset when the value is set to true. A Test asset can help evaluate the Mux Video APIs without incurring any cost. There is no limit on number of test assets created. Test asset are watermarked with the Mux logo, limited to 10 seconds, deleted after 24 hrs.
Arbitrary user-supplied metadata set for the asset. Max 255 characters.
The live stream only processes the audio track if the value is set to true. Mux drops the video track if broadcasted.
Describes the embedded closed caption configuration of the incoming live stream.
A name for this live stream closed caption track.
Arbitrary user-supplied metadata set for the live stream closed caption track. Max 255 characters.
The language of the closed caption stream. Value must be BCP 47 compliant.
CEA-608 caption channel to read data from.
Configure the incoming live stream to include subtitles created with automatic speech recognition. Each Asset created from a live stream with generated_subtitles configured will automatically receive two text tracks. The first of these will have a text_source value of generated_live, and will be available with ready status as soon as the stream is live. The second text track will have a text_source value of generated_live_final and will contain subtitles with improved accuracy, timing, and formatting. However, generated_live_final tracks will not be available in ready status until the live stream ends. If an Asset has both generated_live and generated_live_final tracks that are ready, then only the generated_live_final track will be included during playback.
A name for this live stream subtitle track.
Arbitrary metadata set for the live stream subtitle track. Max 255 characters.
The language to generate subtitles in.
Unique identifiers for existing Transcription Vocabularies to use while generating subtitles for the live stream. If the Transcription Vocabularies provided collectively have more than 1000 phrases, only the first 1000 phrases will be included.
When live streaming software disconnects from Mux, either intentionally or due to a drop in the network, the Reconnect Window is the time in seconds that Mux should wait for the streaming software to reconnect before considering the live stream finished and completing the recorded asset. Max: 1800s (30 minutes).
Reduced and Low Latency streams with a Reconnect Window greater than zero will insert slate media into the recorded asset while waiting for the streaming software to reconnect or when there are brief interruptions in the live stream media. When using a Reconnect Window setting higher than 60 seconds with a Standard Latency stream, we highly recommend enabling slate with the use_slate_for_standard_latency option.
By default, Standard Latency live streams do not have slate media inserted while waiting for live streaming software to reconnect to Mux. Setting this to true enables slate insertion on a Standard Latency stream.
The URL of the image file that Mux should download and use as slate media during interruptions of the live stream media. This file will be downloaded each time a new recorded asset is created from the live stream. If this is not set, the default slate media will be used.
This field is deprecated. Please use latency_mode instead. Latency is the time from when the streamer transmits a frame of video to when you see it in the player. Set this if you want lower latency for your live stream. See the Reduce live stream latency guide to understand the tradeoffs.
Each Simulcast Target contains configuration details to broadcast (or "restream") a live stream to a third-party streaming service. See the Stream live to 3rd party platforms guide.

Latency is the time from when the streamer transmits a frame of video to when you see it in the player. Set this as an alternative to setting low latency or reduced latency flags. The Low Latency value is a beta feature. Read more here: https://mux.com/blog/introducing-low-latency-live-streaming/
True means this live stream is a test live stream. Test live streams can be used to help evaluate the Mux Video APIs for free. There is no limit on the number of test live streams, but they are watermarked with the Mux logo, and limited to 5 minutes. The test live stream is disabled after the stream is active for 5 mins and the recorded asset also deleted after 24 hours.
The time in seconds a live stream may be continuously active before being disconnected. Defaults to 12 hours.
