Just-in-time generation of HLS assets

Primetime Origin Server supports just-in-time (JIT) creation of HLS assets, such as ts and m3u8 from HDS assets created by Primetime Packager or Encoders.

For more information, see the Adobe Primetime Delivery Protocol Specification document.

For every HDS live or VOD stream published to Primetime Origin, the corresponding HLS stream is available by default through JIT-conversion.

Following are the prerequisites for HDS to HLS JIT-conversion:

• The HDS stream published to the Origin Server should follow the Adobe Primetime Delivery Server protocol.
• The published HDS stream should not be DRM protected. For DRM-protected HDS stream, the request for corresponding JIT-converted HLS stream returns a 403 response code (forbidden). To enable encryption on such streams, use JIT-encryption. Encryption configuration should be specified in the stream.xml or vod.xml and then both the HDS and corresponding JIT-converted HLS stream are JIT-encrypted.
• HDS stream should not contain external bootstrap. In the Stream configuration on Origin Server, the WriteExternalBootstrap tag shouldn't be set to true. For such a stream, the request for corresponding JIT-converted HLS stream returns a 403 response code (forbidden).
• The f4m published should contain either the fragmentDuration attribute in the bootstrapInfo element or the targetDuration element under the manifest element. These are required to determine the target duration for HLS stream.
