SCTE35 Module

// See ISCTE35 for methods & ISpliceInfoSection for results.

    import { SCTE35 } from "scte35";
    const scte35: SCTE35 = new SCTE35();
    const result = scte35.parseFromB64("<base64 string>");

CLI

The parser can be executed from the bin by first installing it globally and then executing the scte35 command:

    npm i scte35 -g
    scte35
    > ? Please provide the SCTE-35 tag that you would like to parse

Parsing defaults to base 64, however hexadecimal can easily be parsed as well using the --hex flag

    #default base64

    #hexadecimal
    scte35 --hex fc3046000113f09fa900fff00506fe000000000030022e4355454940012b817fbf091f5349474e414c3a386953773965516946567741414141414141414242413d3d370303689e9165

    #both will output the formatted JSON

        "tableId": 252,
        "selectionSyntaxIndicator": false,
        "privateIndicator": false,
        ...
    }

Piping

The parser output can be piped into other tools, such as a JSON display utility like fx in order to visualize the JSON object and interact with it.

    npm i -g fx
    scte35 /DBGAAET8J+pAP/wBQb+AAAAAAAwAi5DVUVJQAErgX+/CR9TSUdOQUw6OGlTdzllUWlGVndBQUFBQUFBQUJCQT09NwMDaJ6RZQ== | fx
