foobar2000 v2.25 preview change log

2025-08-04

UPnP streaming reliability improvements.
Mac: Fixed main menu rendering bugs (missing checkmarks in submenus, duplicate output device submenu).

Fixed a regression preventing optimal audio device bit depth from being detected, was always reported as 16-bit.
Prevented file-relative:// and mac-volume:// paths being saved in M3U playlists.
Less aggressive audio prebuffering.

Mac: Visualizations - fixed falling peaks for blank bars not being drawn.
Cleaned up various inconsistent behaviors of filesystem API, correct read-ahead option is once again used for SMB.
Reverted 2024 change breaking titles in local M3U playlists referencing internet radio M3U.
Fixed extreme memory usage of visualizations with specific file types.
Made title formatting date functions not throw C++ exceptions when fed input they can't process.
Improved handling of AAC radio streams that have both ID3 tags and icy metadata.

Fixed a problem with yesterday's HTTP bug fix that broke adding whole local folders, by drag&drop etc.

Enabled RF64 writing in Converter.
Amended WavPack in Matroska interaction with Verifier.
Added advanced preferences toggle for alternate multi-value MP4 tag storage - more compatible with specific apps but less compatible with others. Old versions of foobar2000 read both schemes.

Fixed a bug that made exotic FLAC configurations unplayable if muxed into Ogg/Matroska/MP4.
Fixed failure to resume internet radio streams after specific patterns of connection issues.
Made Verifier detect multichapter files with FLAC-style audio MD5, now prompts to scan as whole.
Improved interaction between Verifier and built-in FFmpeg decoders; more errors get reported.

Fixed ID3 tags in AAC radio stream causing playback to stop.
Fixed "wrong URL format" error trying to list SMB server root folder without slash after hostname.
Windows: Improved screen reader behavior in Verify Integrity results dialog.
Made "Edit Chapters" show progress dialog when manipulating files, avoid unresponsive UI when rewriting large MP4.
Tweaked MP4 tag padding to rewrite large files less.

Amended prebuffering code, no longer outputs very large chunks, which caused some DSPs to behave erratically.
Fixed regression from the last build causing very short music files not to be played.
Mac: Fixed erratic behavior of Properties dialog on multi line tags with Windows style line endings.

Playback prebuffering logic update, should fix stuttering with high-res internet radio streams.
Windows: Slightly updated Album List search box, made delay setting take immediate effect; previous behavior required reopening Album List to take effect.
Re-enabled decoding of xHE-AAC thru alternate decoders, as FFmpeg decoder is still buggy. This means aac_at decoding on Mac OS.
Mac: Cleaned up external FFmpeg decoder preferences.
Media Library made properly keep track of enabled decoders list; made remember which decoder was used for each file, so only affected files will be reloaded after uninstalling or disabling of specific decoder.
Media Library added 'clean flag' to know if a rescan of specific folder actually completed; fixes upgrading from foobar2000 v1.x with no scan-on-startup folders becoming empty.
Mac: Properties dialog properly allows multi-line fields.
Windows: Properties dialog no longer garbles lyrics etc with Unix style line endings.
Mac: Album List preferences allows multi-line patterns.

Made Media Library not touch files with .bak, .bk, .off extensions, in addition to .tmp and .temp which were already ignored before.
Fixed UPnP streaming crash.
Added an option to suppress detection of renamed files, overriding new v2.0+ behavior of recognizing common music formats with wrong extension.
Fixed startup crash if importing malformed foobar2000 v1.x configuration.
Windows: Made ARM reported correctly in crash report OS version field (was "x64" before).
Windows: Fixed "add files" not remembering last used folder.
Windows: New VC runtime again.
Mac: Slightly refreshed FFmpeg adapter settings page.

FFmpeg updated to current git master, fixed more xHE-AAC decoding bugs.
Windows: Made internal cover art reading routines respect embedded color profiles.
Windows: Fixed failure to negotiate playback format on some exotic audio devices.

Fixed playing track info possibly becoming out of sync when using seekbar near track switch.
Windows: Fixed initial directory not being set correctly in folder picker regression.

Made live playback info manipulation match behaviors of old foobar2000 versions better, should fix Internet radio issues.
Windows: Removed dotted lines from various treeviews, refreshed Album List tree looks.
Windows: Fixed bad import of relative library paths when upgrading from portable install of old version.
Windows: More verbose output on "open containing folder" errors.

Windows: Fixed unintended capture of ctrl+shift+left/right by tab containers.
Internet radio album art lookup regression fix.
Amended handling of dynamic info (live bitrate etc), the behavior in previous build was causing OpenMPT visualization to malfunction.
Monkey's Audio updated to 11.10.
