Migration from @tedconf/fessonia package to fessonia

• Updated documentation and README file to point links to new repo home at https://github.com/fessonia/fessonia and new documentation home at https://fessonia.github.io/fessonia.
• Updated package.json and associated config to publish at fessonia instead of @tedconf/fessonia.

Bug Fixes

• TypeScript types module kind fixes (PR #45 by @andrewbranch)

CI Changes

• Update of package-lock.json lockfile version from 1 to 2, npm audit fixes to dev dependencies. No impact on production code. (773ba42)
• Dependabot update of dev dependency lodash. No impact to production code. (PR #47)
• Dependabot update of dev dependency y18n. No impact to production code. (PR #46)

• View the commits.
• View the docs.

New Features

• Added TypeScript support with types defined in the types folder. (PR #44 by @universalhandle and @glensc)

Bug Fixes

• Fix improper use of the Config singleton object, and update docs accordingly (PR #43 by @universalhandle)

2.1.2 (2020-08-07)

• View the commits.
• View the docs.

Internal Changes

• Refactor of command string creation within FFmpegCommand, FFmpegOutput and FFmpegInput to reduce repeated code for concatenation and option value quote handling. (PR #40)

2.1.1 (2020-08-07)

• View the commits.
• View the docs.

Bug Fixes

• A bug (Issue #38) in command string generation preventing quoting of option values starting with - was fixed. (PR #39)

CI Changes

• Remove node 8 from Travis CI config, and bump the default node version to 12.15.0. This is in response to the Node.js February 2020 security releases addressing CVEs CVE-2019-15604, CVE-2019-15605, and CVE-2019-15606.
• Convert from using the nyc library for test coverage reporting to using c8, which uses V8's internal coverage metrics. This change was made due to bug instanbuljs/nyc#619, whereby reported line numbers in error stack traces from tests are incorrect, as well as for generally more simplicity in the test run.
• Dependabot update of dev dependency acorn. No impact to production code. (PR #32)
• Dependency update of dev dependency minimist. No impact to production code. (4b63ea2)

• View the docs.

Bug Fixes

This release alters the way filter pad names are handled by the library.

• FilterChain output pad names are only applied in the command output (cmd.toString() and cmd.toCommand()) when streamSpecifier() is called on the FilterChain object. This fixes bug #24 (explicit output pad names added to commands where streams were not explicitly mapped, breaking resulting the ffmpeg command).

Internal Changes

• The library now applies predictable names to output pads of FilterChain objects, replacing the previously used salted hash with a structure that provides for replication of output when running the same code multiple times.
• The FilterNode class has been altered to remove live ffmpeg-based validation and information retrieval for filters and their arguments, relying on ffmpeg to error when filters and arguments are not correct. This decision was made because the complexity in code and automated testing added by this validation were considered to be far greater than the protection provided by such validation.

Documentation Changes

• A section has been added to the About Fessonia guide explaining how stream specifiers are used and what to expect when using explicit mappings.

2.0.0 (2019-12-03)

• View the commits.
• View the docs.

Breaking Changes

This release alters the way run log and progress log output from ffmpeg is handled by the library:

• The library now modifies the specified ffmpeg command by default, adding the -progress global option for use in eventing on progress updates. To disable this, you can pass false to the spawn method of FFmpegCommand.
• Run log returned by FFmpegCommand no longer includes progress lines, as those are treated as ephemeral and only used to generate the events.
• The FFmpegCommand no longer emits failure events, instead emitting error events with appropriate information on any ffmpeg failure with a new FFmpegError object.

Documentation Changes

Documentation has been updated to reflect the new progress and log handling.

New Features

This initial version provides an implementation of the core features:

• FFmpegCommand supporting execute and spawn and integrating a FilterGraph as part of the command
• FFmpegInput and FFmpegOutput supporting the various options supported by ffmpeg

Documentation Changes

Documentation auto-generation capability, as well as several tutorials and informational documents were created and published with this release. Documentation for this release can be found at https://fessonia.github.io/fessonia/1.0.0/.
