Quicktime AAC Encoder: qaac und qtaacenc

    [qaac] release 2.46 (refalac 1.46)

    Code
    Fixed an issue on DLL loading: when a DLL qaac tries to load depends on other missing DLLs, OS was showing a modal dialog which effectively stopped the process until it is closed.
Allow -A option for refalac to be compatible with qaac.

    [qaac] release 2.47 (refalac 1.47)

    • Large file (>= 4GB) output is now supported. Very long duration (beyond 32bit limit) is also supported, but the latter is not compatible with QuickTime 7.

      On very large files, container optimization can take several minutes. You can disable it by --no-optimize.

    Und wem die 19 MB große Datei icudt49.dll aus dem portablen DLL-Set aus iTunes 12.1 zu groß ist, der kann sie ersetzen mit einem Dummy. (auch im Anhang)

    [qaac] release 2.49

    Code
    Fixed issues on MP4Source:
Fixed handling of Nero style chapters starting from non-zero timestamp (typically inserted by fb2k and old neroaacenc).
Fixed handling of reading MP4 files with multiple elst entries.

    [qaac] release 2.50

    Code
    Better support for *****ded cuesheet.
When cuesheet is *****ded in an input file, qaac was encoding it into an single output file with chapters.
From this version, qaac now splits into multiple tracks by default (same as the case of external cuesheet). If you still want single output, use --concat.

    [qaac] release 2.51

    Code
    Always write zero into avgBitrate field in esds decConfigDescriptor to be spec compliant. Was writing actual average bitrate before (this was automatically done by libmp4v2). The spec says that in case of VBR, is should be zero.
Write iTunes compatible "Encoding Params" tag.
Details on Encoding Params tag.
In this (binary) tag, encoding mode(CBR/ABR/CVBR/TVBR), bitrate, and the codec version is written. As far as I know, this tag is only used by iTunes to show bitrate and show if it is VBR or not.


For the sake of compatibility with iTunes, qaac writes nominal (target) bitrate into this tag, and iTunes will show this value when "Encoding Params" tag is present. Therefore, now the result of -v 256 encoding will always look like "256kbps (VBR)" in iTunes.


On the other hands, other (spec compliant) tools will show actual bitrate.

    [qaac] release 2.52

    • Increased MSVC runtime limit of open files to 2048.
      qaac tries to open all the input files before encoding. Previously, qaac couldn't open more than 512 files at once due to CRT limit. Now limit is increased to 2048.
    • Show meaningful error message on CRT level file open error.

    2.56

    Code
    Allow path separators (slash or back slash) in --fname-format, and automatically create directory hierarchy according to the spec given by --fname-format.
Fixed a typo (--tag:geID tag was ignored because of this).
Added debugger output.

    2.57

    Code
    New option: --tag-from-file. This option is similar to --tag, but tag value is read from a file. Character encoding is guessed, but you can specify it by --text-codepage.
New option: --copy-artwork. When specified, front cover art is copied from source file. When --artwork is also specified, this option is ignored. Artwork can be resized by --artwork-size.
Better support of tags in files referred from a cuesheet. Now they are also imported.
Disallow decoding FLAC file via libsndfile. If you want FLAC, use libFLAC.
Ogg Vorbis decoding support via libsndfile.

    2.59


    Code
    [B]Fix:[/B] Was failing encoding mono AAC to AAC.
Support Wavpack v5 interface (with large file support)
Wavpack version 5 is still in alpha state, and DLL is not officially provided. If you want to try it, you have to build it yourself from the source code.


This version of qaac supports both of old and new Wavpack DLL (they are binary compatible). When new functions provided in version 5 library are detected, qaac will use them.

    2.60

    Code
    Fix: combination of --adts and --concat was generating invalid AAC file.
Changed 7.1ch rear channel layout in favor of Apple QuickTime.
Support new Wavpack v5 64bit API
Update: libsoxr
Update: taglib
qaac was using 3 front + 2 side + 2 back for 7.1ch rear output. However, it turned out that Apple QuickTime cannot handle this, and only recognizes 3 front + 4 back. OTOH, libavcodec couldn't recognize the latter until this patch http://ffmpeg.org/pipermail/ffmpeg-cvslog/2015-June/090556.html. Anyway it now handles both, so I decided to change 7.1ch rear layout to 3 front + 4 back, which is supported by both of them

    Für Version 2.60 wird aktuell eine falsche 7.1-Kanalreihenfolge gemeldet.

    [qaac] release 2.61

    Fix 7.1ch PCE: was incorrectly writing object_type(2) instead of profile(1). AFAIK, this doesn't seem to actually affect decoders because decoders are only interested in channel layouts in PCE, but still it was incorrect, and should be fixed.
