Technical Plugin Blackblaze_B2
Transfers media to Backblaze B2 and generates public or authorized object URLs.
Audience: developers, advanced administrators and AI-assisted diagnosis. Plugin catalog.
- Review date: 2026-10-29. Method: static source analysis; runtime/provider behavior was not exercised.
- Code ownership: independently versioned plugin repository.
- Reported version:
4.7. - Source revision:
3662f252ae8c6972b635baf4e48720a60d07730f. - Entry class file: Blackblaze_B2.php.
Confirm the installed plugin version independently of the Streamer version. Configuration defaults below are not a dump of this installation's saved settings.
Public and private URL paths differ. Verify the selected object key and authorization path together. HLS delivery needs playlists, segments and keys, not just one master object.
No literal dependency declaration was extracted. This does not prove the plugin is standalone.

No CREATE TABLE names were extracted from available plugin SQL. The plugin can still use core tables, PHP-created schema or another component's data. Apply installation/update behavior through the owning plugin; this reference is not a script for running historical migrations manually.
Visibility and implementation semantics must be checked in source. Nonempty string defaults are represented as . This is a symbol reference, not a stable public API promise.

- Check the installed/enabled version and the dependencies/settings above.
- Identify the actual failing page, request, callback or worker and correlate its timestamp with the AVideo log.
- Follow the linked method and caller. Check business-state changes and output artifacts as well as HTTP status.
- Reproduce the relevant workflow in a test environment. External provider, Encoder, live-server, storage, payment and authenticated flows require their real integrations.
Shared diagnostic workflow. This page is not a security audit or a claim of end-to-end validation.
