Resuming loaded the file from the start and sought on FileLoaded. By
then mpv's demuxer had begun reading ahead from the beginning, so the
blocks the seek wanted queued behind ones fetched to be thrown away.
Player::play_from sets mpv's start option instead, and puts it back
once the file has loaded.
VideoStream::warm_resume fetches, beside the two edge blocks, the block
the resume position falls in, estimated from the running time saved
with the watch state. A video's bitrate is uneven, so it can land a
block off; then it is one block for nothing, against a round trip saved
when it lands.
A Proton account is now optional alongside public links. Signing in (password,
then a second-factor code and a mailbox password where the account has them;
a CAPTCHA gate is solved in the Android app) stores one session blob in the OS
credential store under `proton-account`, writing back every refreshed token
since refresh tokens are single-use. With an account, folders of the viewer's
own Drive — My Files, other devices, shared with me — can be added as shares
through the same `ShareClient` surface as a public link.
Watch history syncs through a `proton-stream` device in that Drive: one
`watch-history/<installation>.json` per installation, so no two devices ever
write the same file. Each sync reads the others and merges per episode, newer
`updated_at` wins, with a deterministic tie-break. It runs at launch, after
sign-in, whenever the player closes and every five minutes. A session that can
no longer refresh signs the app out instead of failing on every launch.
The CLI gains `login`, `logout`, `account`, `browse` and `sync`.
Also in this change:
- Android offline downloads no longer look stuck (B64): two transfer at once,
through a copy stream with no read-ahead, with a smoothed transfer rate.
- Choosing a metadata match by hand now enriches the title too, instead of
keeping the old match's episodes and artwork.
The catalog schema is unchanged.
A block the player waits for no longer waits on its disk-cache write and
two fsyncs; the put runs in a spawned task and only the block itself is
synced before the rename. Opening a stream can fetch the first and last
block together, where MKV cues and the MP4 moov live. Downloads open a
copying stream that reads the disk cache but never fills it.
crawl_reporting reports the running file count after each listing.
