DownloadInfo doesn't have a 'filename' attribute by default — it's only
set dynamically in update_status when a 'downloaded' status is received.
When captions are silently skipped by yt-dlp (no matching language), the
'downloaded' status is never emitted, so 'filename' doesn't exist on the
object at all. Using getattr(download.info, 'filename', None) instead of
direct attribute access prevents AttributeError.
Two fixes for captions downloads:
1. Language variant fallback: When user requests 'en' but the video only
has 'en-GB' (or other regional variants), yt-dlp silently skips
subtitle extraction because it uses exact language matching. Now the
subtitleslangs list includes common regional variants (e.g. en-US,
en-GB, en-AU, etc.) so yt-dlp can match the first available variant.
2. Error on no files: When yt-dlp completes successfully (ret=0) but
produces no subtitle files (e.g. no matching language at all), the
download was incorrectly shown as 'completed'. Now it's marked as
'error' with a descriptive message like 'No subtitles found for
language "en"'. Same treatment for thumbnail downloads.
- Reset download_phase when transitioning to paused (pause(), update_status(),
_post_download_cleanup()) so UI shows 'Paused' instead of stale phase label
- Reset download_phase when starting/resuming download (start() preparing state)
- Count 'postprocessing' as active download in updateMetrics() so dashboard
shows accurate counts during ffmpeg post-processing
- Add missing completedDownload Subject to DownloadsServiceStub in app.spec.ts
- Add Download type import to app.spec.ts
Fixes: TypeError Cannot read properties of undefined (reading 'pipe')
at app.ts:300 (completedDownload not in test stub)
- _download_phase_from_status now falls back to checking requested_formats
when top-level vcodec/acodec are both 'none' (common when yt-dlp uses
separate downloaders for video+audio streams)
- Clear download_phase on download completion/error (was persisting stale
phase value in finished state)
- Add debug logging in put_status for phase detection
- Update docker-compose.local.yml to match docker-compose.yml structure
with local image build (adds TARGETARCH build arg)
- Removed shadow from URL entry wrap in app.html for a cleaner look.
- Updated various icon files to improve visual consistency across the application.
- Add suffix to identify different files of same video
- Fixed invisible download for short link
