Patches sent on the ffmpeg-devel mailing list for review:

List of commits during GSoC period:

Tasks completed:

  • Working MLP and TrueHD encoder
  • MLP supports multiple channel layouts
  • TrueHD has experimental support for multiple channel layouts (Not guaranteed to work on hardware, but is decodable by ffmpeg)

Tasks currently working on:

  • Provide stereo downmix substream in TrueHD so that it is guaranteed that it plays on all hardware
  • Fix some issues with lossless checks that arise with LFE channels and s32 (24-bit) audio. Once this is fixed we can enable 24-bit support in the encoder.
  • (Optional) Write the bistream verifier, similar to those present in proprietary encoders for MLP and TrueHD.
