OvenMediaEngine Configuration for DRM

OvenMediaEngine Enterprise supports Widevine and Fairplay in LLHLS streams with a simple setup since version 0.16.0.0-1.

Configuration Steps

Specify the DRM Info File Path

You can set the relative or absolute path of the DRM Info File (.xml) relative to the directory where Server.xml is located:

<LLHLS>
    <ChunkDuration>0.5</ChunkDuration>
    <PartHoldBack>1.5</PartHoldBack>
    <SegmentDuration>6</SegmentDuration>
    <SegmentCount>10</SegmentCount>
    <DRM>
        <Enable>false</Enable>
        <InfoFile>path/to/file.xml</InfoFile>
    </DRM>
    <CrossDomains>
        <Url>*</Url>
    </CrossDomains>
</LLHLS>

Configure the DRM Info File

You can apply dynamic changes to the file by separating the DRM Info File (.xml). The changes will be applied whenever a new stream is created.

Here's how you should structure your DRM Info File:

<?xml version="1.0" encoding="UTF-8"?>

<DRMInfo>
    <DRM>
        <Name>MultiDRM</Name>
        <VirtualHostName>default</VirtualHostName>
        <ApplicationName>app</ApplicationName>
        <StreamName>stream*</StreamName> <!-- Can be a wildcard regular expression -->
        <CencProtectScheme>cbcs</CencProtectScheme> <!-- Currently supports cbcs only -->
        <KeyId>572543f964e34dc68ba9ba9ef91d4xxx</KeyId> <!-- Hexadecimal -->
        <Key>16cf4232a86364b519e1982a27d90xxx</Key> <!-- Hexadecimal -->
        <Iv>572547f914e34dc68ba9ba9ef91d4xxx</Iv> <!-- Hexadecimal -->
        <Pssh>0000003f7073736800000000edef8ba979d64acea3c827dcd51d21ed0000001f1210572547f964e34dc68ba9ba9ef91d4c4a1a05657a64726d48f3c6899xxx</Pssh> <!-- Hexadecimal, for Widevine -->
        <!-- Add Pssh for FairPlay if needed -->
        <FairPlayKeyUrl>skd://fiarplay_key_url</FairPlayKeyUrl> <!-- FairPlay only -->
    </DRM>
    <DRM>
        <Name>MultiDRM2</Name>
        <VirtualHostName>default</VirtualHostName>
        <ApplicationName>app2</ApplicationName>
        <StreamName>stream*</StreamName> <!-- Can be a wildcard regular expression -->
         ...........
    </DRM>
</DRMInfo>

Multiple <DRM> can be set. Specify the <VirtualHostName>, <ApplicationName>, and <StreamName> where DRM should be applied. <StreamName> supports wildcard regular expressions.

Currently, <CencProtectScheme> only supports "cbcs" since FairPlay also supports only cbcs. There may be limited prospects for adding other schemes in the near future.

<KeyId>, <Key>, <Iv>, and <Pssh> values are essential and should be provided by your DRM provider. <FairPlayKeyUrl> is only needed for FairPlay and if you want to enable FairPlay to your stream, it is required. It will be also provided by your DRM provider.

Currently, DRM is only supported for H.264 and AAC codecs. Support for H.265 will be added soon.
