Version 1.0

The multiplatform nablet IMF SDK includes tools for muxing and de-muxing of IMF files.

The Interoperable Master Format (IMF) is a SMPTE standard for the file-based interchange of content with multiple versions. It evolved from digital cinema, and is growing rapidly in popularity among broadcasters, OTT providers and many other content-centric businesses. The nablet IMF SDK includes a sample application to generate IMF-compliant XML for existing MXF files. An additional sample shows demuxing of an IMF packing list, and remixing MXF to IMF.

It is provided as a 32- and 64-bit C++ SDK. GStreamer and DirectShow modules are planned. The toolkit is available for Windows, macOS and Linux.

The nablet IMF SDK works well with nablet MXF, MPEG-2 and H.264 encoder and decoder SDKs.

n_demux_mxf.lib – MXF demuxer

n_imf_composer.lib – IMF composer to generate XML files

n_imf_demuxer.lib – IMF demuxer

n_imf_muxer.lib – IMF muxer

n_mux_mxf.dll – MXF demuxer

same as bin64 but 32-bit platform

All necessary includes

imf_composer_test – sample application showing how to generate IMF XMLs for existing MXF files
test_imf_demux – sample showing how to demux IMF packing list
test_mxf2imf – sample showing how to remux MXF file to IMF files set

Known Issues

Due to the limited available test cases there are some known limitations:

  • The IMF muxer and composer does support IMF Application #2, i.e. ST 2067-20:2016 (j2k + pcm streams). Other applications like IMF Application #3 (MPEG-4 Visual Simple Studio Profile) may generate errors. We appreciate your feedback to help us fix any problems that may occur.
  • Multiplexing of ancillary data track may generate errors. We appreciate your feedback to help us fix any problems that may occur.
  • The IMF demuxer does support packing list parsing and demuxing. Parsing for composition playlists is not currently supported.
  • The IMF demuxer will try to demux all formats known for low-level MXF demuxer.
