Photon

Photon is a Java implementation of the Interoperable Master Format (IMF) standard. Photon offers tools for parsing, interpreting and validating constituent files that make an Interoperable Master Package (IMP). These include:

AssetMap (ST 429-9)
PackingList (ST 429-8)
Composition Playlist (ST 2067-3)
IMF track files (ST 2067-5)

Photon parses and reads IMF track files and serializes the metadata into the IMF Composition Playlist structure. Currently, Photon provides support for IMF Application #2E (ST 2067-21) and Application #5 ACES (ST 2067-50), and the Immersive Audio Bitstream (IAB) Plug-in (ST 2067-201).

The goal of the Photon is to provide a simple standardized interface to completely validate an IMP.

Build

JDK requirements

Photon can be built using JDK-8. Support for earlier jdk versions has not been tested and/or verified.

Gradle

Photon can be built very easily by using the included Gradle wrapper. Having downloaded the sources, simply invoke the following commands inside the folder containing the sources:

$ ./gradlew clean
$ ./gradlew build

For Windows

$ gradlew.bat clean
$ gradlew.bat build

Binaries

Binaries and dependency information for Maven, Ivy, Gradle and others can be found at http://search.maven.org.

Change history and version numbers are available at CHANGELOG.md.

Example for Maven:

<dependency>
    <groupId>com.netflix.photon</groupId>
    <artifactId>Photon</artifactId>
    <version>0.1.1</version>
</dependency>

and for Ivy:

<dependency org="com.netflix.photon" name="Photon" rev="0.1.1" />

If you need to download all dependencies, you just have to run:

$ ./gradlew getDependencies

It will download all dependencies into ./build/libs directory, where Photon.*.jar is built. Multiple sample applications have been provided with this project (e.g., com.netflix.imflibrary.app.IMFTrackFileReader). Having obtained the dependencies, you can run an application as follows:

java -cp ./build/libs/*: <fully qualified class name> <zero or more arguments>

E.g.,

java -cp ./build/libs/*: com.netflix.imflibrary.st0429_9.AssetMap asset_map_file_path

java -cp ./build/libs/*: com.netflix.imflibrary.st0429_8.PackingList packing_list_file_path

java -cp ./build/libs/*: com.netflix.imflibrary.st2067_2.Composition composition_playlist_file_path

java -cp ./build/libs/*: com.netflix.imflibrary.app.IMPAnalyzer IMP_folder_path

For Windows please refer to the following examples
