- Add requires to load seq-... and string-trim-right functions during
compilation.
- Reorder code to fix warnings about free and undeclared variables.

v2.4 does not enclose genre references in parentheses.

Frames are assumed to be key/value pairs. If key is an info-field
identifier, return the value for that info-field.
|
| |
|

Use TDRC for info-date. Also add some more well-known tags so that
id3v2 can provide the same info-fields than Vorbis.

Don't try to trim nil.

TDRC (‘Recording time’), TDRL (‘Release time’) and TDOR (‘Original
release time’) frames in id3v2.4 are time stamps, not years, so they
should go to info-date and info-originaldate fields instead of
info-year and info-originalyear.

- Remove id3v2 size checks agains emms-info-native--max-peek-size.
Decoded sizes do not guide memory reservation anymore so checks are in
that sense redundant. Trigger errors on zero-sized elements though,
because they are always wrong.
- Verify frame identifiers.

- Allow zero-sized frames; in practice they mean start of padding.
- Do not try to read frame headers going over tag boundary. These
cases also mean start of padding in practice.
- Return nil from emms-info-native--decode-id3v2 in case of
errors *or* if there were no useful metadata.

Instead of reading the whole tag and then parsing it, do reading and
parsing one frame at a time, and skip uninteresting frames.
This may conserve memory and give better performance in some cases.

Extract "artistsort", "titlesort", "albumsort" and few more "year" and
"originalyear" frames.

- Tag-level id3v2 unsynchronization is now supported. Frame-level
unsynchronization is still missing, and likely won’t be implemented at
all.
- Fix frame size decoding between different id3v2 versions.
- Use correct id3v2.2 sizes during decoding.
- Remove a terminating null byte from text strings only if there is
one.

The value was wrong and not used anyway.

Constructs are now ordered from generic to specific ("top-down") and
are thus, hopefully, easier to follow.

Clean up block decoder and fix incorrect last-flag calculation.

It seems that bindat specs cannot refer outside themselves, so use a
special variable ‘emms-info-native--opus-channel-count’ with dynamic
binding to keep track of channel count.

These are only stylistic changes.

Split long functions to smaller functions that are easier to
understand.

Also adjust Ogg and FLAC decoders to return info fields in a unified
format.
|
|
|
This info method is a pure elisp implementation for Ogg Vorbis, Opus and
FLAC file formats.
