ZEC Adding SRT Client Streams

srt (secure reliable transport) is an open source video streaming protocol that brings pristine quality, low latency live video over the public internet this input enables the zec to pull an srt stream from the source the connection is initiated by zec the connection can be password protected more details about srt can be found at secure reliable transport (srt) https //www haivision com/products/srt secure reliable transport/ reference broadcaster versions and their associated srt library version 19 srt library 1 5 5 version 18 srt library 1 5 4 version 17 srt library 1 5 3 version 16 srt library 1 4 4 see the steps below to override the default srt library with an older version for compatibility with a downstream system to add an srt client stream in the zec navigation menu, click the inputs tab in the menu bar, click +new input the add a new input stream window is displayed enter the unique stream id note this must be identical (case sensitive) to the stream name configured in the sending zixi broadcaster or mediaconnect select the maximum concurrent connections to this stream from the max outputs drop down list default unlimited select the show in matrix check box to display this stream in the matrix (see zec using the matrix docid\ ofxethpsuo9eimqpwfzea ) default selected select srt client for the input stream if you want to override the default version of the srt library used for compatibility with downstream systems, select the desired version from from srt version selector specify the stream parameters (see the input stream parameters table docid\ y8qqt126dvjuic1khzbwz below) if you want to enable encryption , select this checkbox (see input stream parameters table docid\ y8qqt126dvjuic1khzbwz ) for more information, see zec encrypting an input stream docid\ qern0zffbaztl vrw4rn if you want to configure the recording parameters , specify them in the respective fields (see input stream parameters table docid\ y8qqt126dvjuic1khzbwz ) click ok the “input added” message appears at the top of the screen the srt client stream is added to zec and now appears in the list of streams available in the zec inputs ui input stream parameters table parameter description stream parameters remote host enter the ip address of the remote server from which the srt stream will be pulled remote port enter the port through which the zec receives the stream from another server remote stream enter the stream id of the stream that is being pulled password if the stream is password protected, enter the password lantency specify the maximum latency of the stream in milliseconds default 1000 max bitrate \[kbps] specify the maximum expected bitrate for memory allocation recommended 2x the actual bitrate, which will prevent buffer overruns (especially with vbr streams) default 10000 note – overflows will typically occur when the max bitrate isn’t sufficient bind to ip select from the drop down list the local ip address to be used for this input, or select any to enable any ip to be used srt version override the default version of the srt library used for compatibility with downstream systems enable encryption encrypts the input stream 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 destination type select the radio button for the desired storage type and then fill in the relevant parameters record to disk – the recording is saved on the local disk it is possible to record to an external destination by replacing the default storage location with a symbolic link to learn more, see the zec using an external storage docid\ va00gdlmr u7oiykgklnx section record to s3 – the file is saved to your aws s3 bucket record to disk parameters 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 %u=yyyymmddthhmmssz utc timestamp – optional for example, the following pattern %y recording%t ts will generate the following file name 2022 recording15 32 35 ts max recorded file duration \[hh\ mm] specify the maximum time allotted for recording a video stream default 2 hours keep recorded files for \[hh\ mm] specify the maximum time for storing the recording default 0 hours 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 record to s3 parameters 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

contains dot\[s] when this option is selected, zec will ignore the tls certificate errors and transmit the stream to its destination access key the access key that is used for accessing the s3 bucket secret key the secret key that is used for accessing the s3 bucket
