coinosv3.git/tools/media-upload-test.js, branch master

Public pictures and videos go to blossom.ditto.pub first, then primal, nostr.download, nostr.build.

A 2026-09-30 benchmark (4 MB mp4, 110 KB jpeg; upload then fetch, twice): ditto took the mp4 in ~0.6 s and serves from ~120 ms; primal ~1.5 s; nostr.download ~1-2 s but rejects a JPEG with data after its end marker (motion photos); blossom.nostr.build ~5 s with ~600 ms first byte.

Videos are shrunk on the phone before upload; nostr.build is the first media host.

No public Blossom host transcodes (nostr.build's and primal's BUD-05 /media return the same bitrate), so a 15-20 Mbps phone clip stalled on playback. src/video-compress.js re-encodes on the device with WebCodecs via Mediabunny (a lazily loaded chunk, left out of the SW precache and the standalone file): H.264, short edge 720, ~2.5 Mbps, moov first, audio passed through, rotation baked in. Anything short of a clear win uploads the original. A toast counts the shrinking down. Media hosts: blossom.nostr.build first, nostr.download second (it was unreachable for hours); a HEAD probe skips a host that doesn't answer within 5 s instead of waiting out the whole upload timeout. video-compress-test: 1080p 20 Mbps 5 s (landscape and rotated portrait) → 1.6 MB H.264 720p 2.49 Mbps with audio, moov first, in 2-3 s.
