Subtitle tracks hang off a version rather than off a video, because re-editing a cut shifts every cue. The file
always lands in our own S3-compatible storage whatever hosts the video, so a Bunny-hosted cut and an R2 one take the
same path: both already play through our own video element, so a track element is all it takes.
Uploads are normalised before they are stored. Whatever arrives, SRT or WebVTT, is parsed into cues and
re-serialised as a canonical WebVTT file, and anything we did not understand is dropped rather than passed through.
That is what makes it safe to serve a user-supplied text file from our own origin. Files saved out of Windows
editors are decoded as windows-1254 or windows-1252 when they are not valid UTF-8, rather than refused.
A YouTube version cannot carry an uploaded track, so the same CC menu drives YouTube's own captions through the
iframe module API. The embed hides YouTube's controls, so until now those captions were unreachable even when the
video had them.
Uploading and deleting take the editor permission rather than the commenter one: a subtitle is part of the
delivered cut, not a comment attachment.
A single speed ladder fed both players, so the 2x cap that YouTube's
iframe API enforces also applied to Bunny and R2, which are plain <video>
elements the browser will play far faster. Pick the ladder per provider:
YouTube keeps 0.25x-2x, the native ones go up to 16x, where Chrome and
Firefox clamp playbackRate. The picker labels everything past 4x as
"no audio", since that is where the browsers stop pitch-correcting and
drop the audio track.
Show a timecode + frame readout above the timeline while dragging the
playhead, and flash it for a moment on keyboard/button seeks so frame
stepping is visible too.
Position and text are written from the existing rAF/DOM path that drives
the playhead, so the readout stays smooth without extra React renders.
Two supporting fixes the count depends on:
- Seed the frame rate from the HLS manifest FRAME-RATE attribute so a
frame number is available before playback ever starts; previously the
rate was only ever measured from requestVideoFrameCallback and stayed
null until the video had played.
- Snap the measured rate to the nearest broadcast standard and skip
samples taken mid-seek. A drifting float slid the count by whole
frames late in a long video, and re-publishing a slightly different
float on every presented frame forced a re-render per video frame.
Drive the timeline progress fill and playhead directly via a
requestAnimationFrame loop (bypassing React state) so the playhead glides
at the display refresh rate during playback instead of stepping ~4x/sec.
Scrubbing now previews frames live like an editor: while dragging, the
video is seeked with coalescing (one seek in flight, chasing the latest
target) so HLS stays responsive without stale-seek pileup. Playback pauses
during a scrub and resumes on release. Dragging tracks the cursor anywhere
on the page via window listeners.
- Added support for self-hosted S3 video uploads with new environment variables: OPENFRAME_ENABLE_S3_VIDEO_UPLOADS and OPENFRAME_MAX_VIDEO_UPLOAD_BYTES.
- Updated .env.example and .env.docker.example to reflect new configuration options.
- Enhanced Content Security Policy to include origins for S3-compatible storage.
- Updated dependencies for AWS SDK to support new features.
- Refactored upload logic to accommodate both Bunny and S3 upload providers.
- Updated documentation to clarify the usage of direct uploads and S3 configurations.
