Video Transcoding v0.15.0 Release Notes

  • Sunday, January 15, 2017

    • Modify convert-video, via #114, to:
      • Add support for text-based and DVD-style image-based subtitles. Please note that Blu-ray Disc-style image-based subtitles are not supported due to MP4 format restrictions.
      • Add a --no-double option which no longer assumes input files might contain two main audio tracks whose order needs to be swapped, or that a "missing" stereo AAC audio track needs to be added to MP4 output.
      • Change the algoritm deciding when a "missing" stereo AAC audio track is added. Previously that only happened when the first track of the input MKV file was in surround format and there were no other audio tracks. Now it won't matter how many audio tracks are in the input.
      • Use ffmpeg and mkvpropedit for conversion to MKV format instead of just mkvmerge which could not convert subtitle formats.
      • Remove the dependency on mkvmerge and add a dependency on mkvpropedit.
      • No longer pass the -strict experimental arguments to ffmpeg when using the built-in, native AAC encoder.
    • 🛠 Fix a bug preventing the detection of whether an audio track had the "default" flag set when parsing scan output from HandBrakeCLI versions 1.0.0 and later. This was caused by the integration of Libav version 12.0 in HandBrake on December 17, 2016.
    • 🛠 Fix a long-standing bug preventing the detection of all subtitles and disambiguation with chapter information in MP4 files when parsing scan output from mp4track.
    • ✂ Remove support for the Freeware Advanced Audio Coder (FAAC) from the "FFmpeg" module since it's no longer included with ffmpeg.
    • ✂ Remove the "mkvmerge.rb" source file and any references to the "MKVmerge" module since convert-video no longer needs it.
    • ⚡️ Update the "README" document to:
      • Remove mkvmerge from the "Requirements" section.
      • Clarify subtitle support in the "Using convert-video" section.
