Allows:
* The HLS player to propose an "Audio only" resolution
* The live to output an "Audio only" resolution
* The live to ingest and output an "Audio only" stream
This feature is under a config for VOD videos and is enabled by default for lives
In the future we can imagine:
* To propose multiple audio streams for a specific video
* To ingest an audio only VOD and just output an audio only "video"
(the player would play the audio file and PeerTube would not
generate additional resolutions)
This commit introduce a new way to download videos:
* Add "/download/videos/generate/:videoId" endpoint where PeerTube can
mux an audio only and a video only file to a mp4 container
* The download client modal introduces a new default panel where the
user can choose resolutions it wants to download
Sorry for the very big commit that may lead to git log issues and merge
conflicts, but it's a major step forward:
* Server can be faster at startup because imports() are async and we can
easily lazy import big modules
* Angular doesn't seem to support ES import (with .js extension), so we
had to correctly organize peertube into a monorepo:
* Use yarn workspace feature
* Use typescript reference projects for dependencies
* Shared projects have been moved into "packages", each one is now a
node module (with a dedicated package.json/tsconfig.json)
* server/tools have been moved into apps/ and is now a dedicated app
bundled and published on NPM so users don't have to build peertube
cli tools manually
* server/tests have been moved into packages/ so we don't compile
them every time we want to run the server
* Use isolatedModule option:
* Had to move from const enum to const
(https://www.typescriptlang.org/docs/handbook/enums.html#objects-vs-enums)
* Had to explictely specify "type" imports when used in decorators
* Prefer tsx (that uses esbuild under the hood) instead of ts-node to
load typescript files (tests with mocha or scripts):
* To reduce test complexity as esbuild doesn't support decorator
metadata, we only test server files that do not import server
models
* We still build tests files into js files for a faster CI
* Remove unmaintained peertube CLI import script
* Removed some barrels to speed up execution (less imports)
Many files from the `shared` folder were importing files from the `server` folder.
When attempting to use Typescript project references to describe dependencies,
it highlighted a circular dependency beetween `shared` <-> `server`.
The Typescript project forbid such usages.
Using project references greatly improve performance by rebuilding only
the updated project and not all source files.
