TODO: divx4/divx5/xvid/3ivx/mpeg-4 - how to make them overlap? (all
ISO MPEG-4 compatible)
Audio codecs
------------
3c) Audio Codecs
----------------
for convenience, the two-byte hexcodes (as are being used for identification
in AVI files) are also given
Preface - (optional) properties for all audio formats:
'rate' = X (int) <- sampling rate
'channels' = X (int) <- number of audio channels
1 - Raw Audio (integer format)
mimetype: audio/x-raw-int
properties: 'width' = X (INT) <- memory bits per sample
'depth' = X (INT) <- used bits per sample
'signed' = X (BOOLEAN)
'endianness' = 1234/4321 (INT)
2 - Raw Audio (floating point format)
mimetype: audio/x-raw-float
properties: 'depth' = X (INT) <- 32=float, 64=double
'endianness' = 1234/4321 (INT) <- use G_BIG/LITTLE_ENDIAN!
'buffer-frames' = (INT)
With regards to the signal: 0.0 represents no signal, +/- 1.0 is 0 dB.
3 - Alaw Raw Audio
mimetype: audio/x-alaw
4 - Mulaw Raw Audio
mimetype: audio/x-mulaw
5 - MPEG-1 layer 1/2/3 audio
mimetype: audio/mpeg
properties: 'mpegversion' = 1 (INT)
'layer' = 1/2/3 (INT)
6 - Ogg/Vorbis
mimetype: audio/x-vorbis
7 - Windows Media Audio 1 and 2 (WMA)
mimetype: audio/x-wma
properties: 'wmaversion' = 1/2 (INT)
8 - AC3
mimetype: audio/x-ac3
9 - FLAC (Free Lossless Audio Codec)
mimetype: audio/x-flac
10 - MACE 3/6 (Quicktime audio)
mimetype: audio/x-mace
properties: 'maceversion' = 3/6 (INT)
11 - MPEG-4 AAC
mimetype: audio/mpeg
properties: 'mpegversion' = 4 (INT)
12 - (IMA) ADPCM (Quicktime/WAV/Microsoft/4XM)
mimetype: audio/x-adpcm
properties: 'layout' = "quicktime"/"wav"/"microsoft"/"4xm" (STRING)
Note: the difference between each of these is the number of
samples packaed together per channel. For WAV, for
example, each sample is 4 bit, and 8 samples are packed
together per channel in the bytestream. For the others,
refer to technical documentation.
We probably want to distinguish these differently, but
I don't know how, yet.
13 - RealAudio (Real)
mimetype: audio/x-pn-realaudio
properties: 'bitrate' = 14400/28800 (INT)
For convenience, the two-byte hexcodes (as used for identification in AVI files)
are also given.
