バージョン履歴

ダウンロードできるのは最新バージョンのみです。以前のバージョンは参考として掲載しています。

1. v2.1.2最新2026年10月28日

   Changed

   • DKB Downloader is now MediaCatch, and it is open source under the MIT license: github.com/dangkhoabach/MediaCatch
   • Your library, watched channels and settings stay as they are. After this update the app in Applications keeps its old file name, DKB Downloader
2. v2.1.12026年9月21日

   Fixed

   • Downloads that failed at the very end with "Couldn't move the finished file to the output folder". This happened when macOS blocked the app from writing to your download folder (usually after clicking Don't Allow on the Downloads-folder prompt), or when the folder was on a drive that's no longer connected
   • The Home screen and Settings now warn you before a download starts, with a button that opens System Settings › Privacy & Security › Files and Folders to allow access again, or one to pick another folder. The warning clears by itself once access is restored
   • The download folder is recreated if it was renamed or deleted
   • When a move does fail, Library shows the actual reason (hover over the red line for the full text) and the downloaded file is no longer deleted
   • Automatic update checks never actually ran: the daily check only started once you had clicked Check for Updates yourself. It now starts at launch

   Changed

   • You decide whether the app checks for updates automatically. The first launch after updating asks once; change your answer any time in the new Settings › Updates section, which also has a Check Now button
3. v2.1.02026年9月18日

   A big update: more control over downloads, better authentication options, and a long list of fixes.

   What's new

   • Download speed limit: cap downloads at 1, 2, 5 or 10 MB/s in Settings, or leave them unlimited
   • Concurrent download limit: choose how many downloads run at once (default 3). The rest wait in Queue as "Waiting" and start automatically when a slot frees up
   • Split by chapter: for videos with chapters, a toggle on the download screen saves one extra file per chapter alongside the full video
   • Import cookies.txt: use an exported cookies file instead of reading a browser's cookie store
   • Subtitle languages: choose which subtitle languages are embedded when metadata embedding is on (default en, vi)
   • Retry from Library: failed and cancelled downloads now have a Retry button
   • Link from clipboard: copy a link and switch to the app, and the URL field is filled for you. Nothing is fetched until you press Fetch; can be turned off in Settings
   • yt-dlp keeps itself current: the download engine checks for a newer yt-dlp on launch and updates in the background. Settings shows the installed version with a "Check for update" button
   • Extraction warnings: if yt-dlp reports a problem while fetching video info (for example, some formats may be missing), the warning is shown on screen instead of being hidden

   Improved

   • Batch mode fetches video info four links at a time instead of one by one
   • A fetch that stalls can be cancelled, and gives a clear message after 90 seconds instead of spinning forever
   • The menu bar and all remaining screens follow the in-app language setting (VI/EN)
   • The bundled yt-dlp and ffmpeg are checksum-verified before every release

   Fixed

   • A finished download was reported as an error when a file with the same name already existed in the output folder. It now gets a " (1)", " (2)"… suffix
   • Download used whatever was in the URL field at the time, not the video whose formats were shown, if the field had been edited after fetching
   • Text starting with a dash was passed to the downloader as an option instead of a URL
   • Pressing Fetch again while a fetch was running could hide the spinner and re-enable the button while the new fetch was still in progress
   • A download that could not start stayed stuck in Queue with Cancel and Pause doing nothing

   Reminder: the first launch of a fresh install needs right-click → Open. Existing installs update automatically through Check for Updates.

4. v2.0.32026年9月2日

   Improved

   • The yt-dlp auto-updater verifies the downloaded binary's checksum before installing it, and installs safely so an interruption cannot leave a partial or corrupt install
   • Deleting a download or a history entry, clearing history and removing a watched channel now ask for confirmation first
   • VoiceOver labels added to icon-only buttons across the app
   • More robust progress-percentage parsing in the Queue view
   • macOS Hardened Runtime enabled for improved security

   Fixed

   • After closing the main window, the app icon lingered as an invisible "ghost" window in Stage Manager
   • Downloads stuck showing "Downloading" forever (after a crash or force-quit mid-download) are now marked as failed so you can retry them
   • Quitting the app now waits for active yt-dlp/ffmpeg downloads to stop cleanly instead of leaving orphaned background processes
5. v2.0.22026年9月1日

   Fixed

   • Switching sidebar tabs (Home, Queue, Library, Watch) no longer resets what you were doing: a fetch in progress, the batch list, Library's search text and Watch's typed channel URL all stay put
   • Library and Home toolbar buttons showed up while a different tab was active
   • Dark/Light → System appearance did not reliably switch back to match macOS
   • The updater sometimes reported a new version even when you were already on the latest one
