Endpoint: GET /transcoders/{transcoder_id}/properties
Version: v2.0

## Path parameters:

  - `transcoder_id` (string, required)
    The unique alphanumeric string that identifies the transcoder.

## Response 200 fields (application/json):

  - `properties` (array)
    An array of properties.
    Example: [{"key":"fitMode","section":"output","value":"letterbox"},{"key":"rtpIgnoreProfileLevelId","section":"rtsp","value":true}]

  - `properties.key` (string, required)
    The key of the property.

The following table lists the available property keys and what transcoder table section they're stored in.

vod_stream | hlslive2vodNote: VOD streams require a Fastly stream target with HLS as a delivery protocol.

  - `properties.section` (string, required)
    The section of the transcoder configuration table that contains the property.
    Enum: "asset_management", "cupertino", "ezdrm", "file", "output", "recording", "rtmp", "rtsp", "srt", "vod_stream"

  - `properties.value` (string, required)
    The value of the property.

The following table provides information about valid values for each property key.

Key(s) | Values for the key
----------------|-------------
aes128Host | Specify the URL that devices will use to fetch the key to decrypt the stream.
aes128Secret | Specify the 16-byte key that will be used to decrypt the stream. The key must be 32 characters in length and can only contain hex characters (a-f, A-F, 0-9). The key must match the key returned by the aes128Host.
enabled | Specify true or false. Used in the asset_mangement section.
fitMode | Use letterbox, fit-width, fit-height, crop, stretch, or match-source. The default is fit-height.
maxRtcpWaitTime | Use a whole number, expressed as a string or an integer. The default is 2000 (ms).
passPhrase | Use a string between 10-79 characters in length. It adds security to a live stream for an incoming SRT stream from your device or encoder to Wowza Video. The password protection secures the data payload of SRT live streams, ensuring that the transmitted content is encrypted and safeguarded against unauthorized interception during its journey across the network.
record | Use an output ID associated with the transcoder.
rtpDePacketizerPacketSorterBufferTime | Use an integer, expressed as a string or an integer. The default is 500 (ms).
rtpDePacketizerPacketSorterFlushTime | Use an integer, expressed as a string or an integer. The default is 10 (ms).
rtpDePacketizerWrapper | Use the string RTPDePacketizerWrapperPacketSorter.
rtpTransportMode | Use the string udp or interleave (the default).
rtspValidationFrequency | Use a whole number, expressed as a string or an integer. The default is 15000 (ms).
start_streaming_at | Specify the month, day, year, and time of day that the file should start streaming, expressed as a string. Express the value by using the ISO 8601 standard of YYYY-MM-DDTHH:MM:SSZ where HH is a 24-hour clock in UTC.
usernamepasswordfairplayAssetIdwideVineContentId | Use account information and asset IDs from EZDRM. All strings.
avSyncMethoddebugRtspSessionmp4repeatrtspFilterUnknownTracksrtpIgnoreSpropParameterSetsrtpIgnoreProfileLevelId | Use true or false, expressed as a string or a Boolean.
hlslive2vod | Use true or false, expressed as a string or a Boolean. When true, hls generates a VOD stream and live2vod replaces the live playlist with the VOD playlist after the stream ends so viewers can access the VOD stream on the live playback URL. hls must be true to enable live2VOD.
