+- src
MSVC solution for Visual Studio 2010 is under MSVC directory.
Available input format
----------------------
WAV, RF64, CAF, RAW, upto 32bit int / 64bit float format is supported.
Metadata in CAF info chunk can be read and copied to the resulting m4a.
This is especially useful and works well when you pipe from ffmpeg via CAF.
For example, you can copy tag from original "foo.flac" to "foo.m4a"
through the following pipeline:
$ ffmpeg -i foo.flac -f caf - | fdkaac -m3 - -o foo.m4a
Since FDK AAC encoder is implemented based on fixed point integer,
encoder itself handles 16bit input only.
Therefore, when feeding non-integer input, be careful so that input doesn't
exceed 0dBFS to avoid hard clips.
You might also want to apply dither/noise shape beforehand when your input
has higher resolution.
Note that fdkaac doesn't automatically resample for you
when input samplerate is not supported by AAC spec.
Tagging Options
---------------
Generic tagging options like --tag, --tag-from-file, --long-tag allows you
to set arbitrary tags.
Available tags and their fcc (four char code) for --tag and --tag-from-file
can be found at http://code.google.com/p/mp4v2/wiki/iTunesMetadata
For tags such as Artist where first char of fcc is copyright sign,
you can skip first char and just say like --tag="ART:Foo Bar" or
--tag-from-file=lyr:/path/to/your/lyrics.txt
Currently, --tag-from-file just stores file contents into m4a without any
character encoding / line terminater conversion.
Therefore, only use UTF-8 (without BOM) when setting text tags by this option.
On the other hand, --tag / --long-tag (and other command line arguments) are
converted from locale character encoding to UTF-8 on Posix environment.
On Windows, command line arguments are always treated as Unicode.
Tagging using JSON
------------------
With --tag-from-json, fdkaac can read JSON file and set tags from it.
By default, tags are assumed to be in the root object(dictionary) like this:
{
"title": "No Expectations",
"artist": "The Rolling Stones",
"album": "Beggars Banquet",
"track": 2
}
In this case, you can simply specify the filename like:
--tag-from-json=/path/to/json
If the object containing tags is placed somewhere else, you can optionally
specify the path of the object with dotted notation.
{
"format" : {
"filename" : "Middle Curse.flac",
"nb_streams" : 1,
"format_name" : "flac",
"format_long_name" : "raw FLAC",
"start_time" : "N/A",
"duration" : "216.146667",
"size" : "11851007.000000",
"bit_rate" : "438628.000000",
"tags" : {
"ALBUM" : "Scary World Theory",
"ARTIST" : "Lali Puna",
"DATE" : "2001",
"DISCID" : "9208CC0A",
"TITLE" : "Middle Curse",
"TRACKTOTAL" : "10",
"track" : "2"
}
}
}
In this example, tags are placed under the object "format.tags".
("format" is a child of the root, and "tags" is a child of the "format").
In this case, you can say:
--tag-from-json=/path/to/json?format.tags
For your information, ffprobe of ffmpeg project (or avprobe of libav) can
output media information/metadata in json format like this.
Note that not all tags can be read/written this way.
