Videos now get a thumbnail generated eagerly server-side on upload, through the same WebP/blob-hash pipeline as photos — instead of the old browser path that only ran when the Photos grid first rendered a video tile, re-downloaded the whole video to seek a frame, and PUT 3 JPEGs back (and produced nothing at all for HEVC/.mov, which a browser <video> cannot decode). - New VideoFramePort (application) + FfmpegVideoFrameService / NoopVideoFrameService (infrastructure): shell out to the system ffmpeg (no compile-time libav dep), extract one representative frame as PNG, bounded by its own semaphore + a per-process timeout + kill_on_drop. Noop when ffmpeg is absent/disabled, so videos degrade gracefully to no thumbnail. - ThumbnailRefreshHook.on_file_created routes video/* to generate_video_thumbnails_background: stream the (decrypted, reassembled) blob to a size- and time-bounded temp file on the data volume, extract a frame, and reuse the shared render_and_persist_all_webp helper — so video thumbnails are WebP, blob-hash keyed (dedup'd) and content-negotiated, exactly like photos. - GET thumbnail serves the video's WebP to every client (byte-sniffed Content-Type); a genuine miss returns 204. - Config: OXICLOUD_ENABLE_VIDEO_THUMBNAILS (default true, needs ffmpeg detected at startup) + OXICLOUD_FFMPEG_PATH / _CONCURRENCY / _TIMEOUT_SECS / _MAX_MB. - Dockerfile installs ffmpeg in the runtime image. - Frontend: drop the client-side generateVideoThumb/frameFromVideo re-download path; the server is now the source of truth. Benchmark (examples/bench_video_thumbnails.rs, needs ffmpeg): 4/4 codecs incl. HEVC/.mov produce a thumbnail server-side (was 0% for HEVC); ~50-70 ms/frame in the background; ~3.9 KB preview WebP; up to ~23x less per-first-view transfer on the test corpus (far more on real multi-MB clips). Methodology in benches/VIDEO-THUMB.md. Hardening from an adversarial review: video render holds the decode_semaphore like the image path; the ffmpeg scale filter bounds both dimensions; the blob stream has a timeout; the temp file lives on the data volume; the size cap uses saturating_mul.
