Photon

Photon is a Java implementation of the Interoperable Master Format (IMF) standard. IMF core constraints are defined by SMPTE specification st2067-2:2013 (paywall). Photon offers tools for parsing, interpreting and validating constituent files that make an Interoperable Master Package (IMP). These include AssetMap (st429-9:2014), PackingList (st429-8:2007), Composition Playlist (st2067-3:2013), and the essence containing IMF track file (st2067-5:2013) which follows the Material eXchange Format (MXF) format (st377-1:2011). Specifically, Photon parses and completely reads an MXF file containing a single audio or video essence as defined by the IMF Essence Component specification (st2067-5:2013) and serializes the metadata into the IMF Composition Playlist structure.

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
