Zixi Broadcaster offers live transcoding, enabling users to create multiple bitrate streams from a single input stream.
...
- Video Decoding – MPEG2, H.264/AVC , H.265/HEVC
- Video Encoding – MPEG2, H.264/AVC , H.265/HEVC
- Audio Decoding – AAC, MPEG-1 Audio Layer I / II / III, MPEG-2 Audio Layer I / II / III
- Audio Encoding – AAC-LC, AAC-HEv1, Opus; Pass through – any audio codec (MPEG1/2 / AAC / AC-3)
...
In order to transcode an input stream from the Inputs screen you must first configure the transcoding profiles in the Transcoder screen. For more information, see Transcodersection section.
To Transcode an Input Stream:
...
Parameter | Description |
|---|---|
| Enable time shift | Enables a delayed transmission of this input. |
| Maximum delay [hh:mm:ss] (for Time Shift enabled) | Specify the maximum time delay of this input. |
| Transmit as multicast | Enables transmission of this stream’s outputs as multicast. A Zixi Receiver will receive it in multicast (unless it is out of the LAN in which case it will receive as unicast). You can also force Multicast only outputs. Requires enabling Multicast Pull in the Settings. |
| Multicast-Only (for Multicast enabled) | If desired, specify multicast only outputs. |
| Enable Encryption | Encrypts the Input stream. For more information, see Encrypting an Input Stream in Zixi Broadcaster. |
Encryption type (for Encryption enabled) | Specify the type of Encryption (AES 128/192/256). |
Encryption key (for Encryption enabled) | Click Generate to generate an encryption key. The generated encryption key must be sent to the end-user to decipher the received encoded stream. |
| Recording parameters | |
Max recorded file duration [hours] | Specify the maximum time allotted for recording a video stream. Default: 2 hours |
Keep recorded files for [hours] | Specify the maximum time for storing the recording. |
| Custom Path | Optionally specify a storage location for the recorded files that is relative to the root folder. This location bypasses the location specified as the root folder in the Settings > General screen. |
| File Name Template | Specify the file name pattern that Zixi will use to generate when saving the recorded content. A separate file will be generated for each recording up to the time specified in the Max recorded file duration parameter (see above). After this duration a new file will be generated. The file name pattern can include any string and up to five variables listed below. Only the %T=HH.MM.SS creation time is mandatory. You can change the order of these variables and add text as long as you maintain the legitimate structure of the file in Linux and Windows: %S=stream id - optional. %Y=year - optional %M=month - optional %D=day - optional %T=HH.MM.SS creation time - mandatory For example, the following pattern %Y_recording%T.ts will generate the following file name2017_recording15:32:35.ts. |
