Liquidsoap 2.1.1

This is the first bugfix release of the v2.1.x release cycle, fixing some minor and less-minor issues. So far, the release cycle seems to be holding up fairly well!

Worth noting:

• ocurl is now a mandatory dependency. Its functionalities, support for http.{get,put,post,..} providing, among other things, remote requests resolution, were already expected by most users.
• Windows build for v2.1.0 did not have the ffmpeg encoders and decoders enabled.. 🤦‍♂️
• playlist.next now returns the requests in the right order. This could be breaking some existing scripts!
• playlist.remaining has been renamed into playlist.remaining_files. This could be breaking some existing scripts!

Full changelog:

2.1.1 (2022-08-28)

New:

• Added process.quote.command to generate complex quoted command strings suitable
  for use with process.run and os-independent.

Changed:

• Renamed playlist.remaining into playlist.remaining_files (#2524)

Liquidsoap 2.1.0

This is the first release of the 2.1.x release branch! 🎉

This version comes with some major improvements and breaking changes. As usual, you can get a (mostly) complete list in the migration page

In particular, the following changes are noticeable:

JSON parsing is greatly improved

You should now be able to do:

let json.parse ({
  foo,
  bla,
  gni 
} : {
  foo: string,
  bla: float,
  gni: bool 
}) = '{ "foo": "aabbcc", "bla": 3.14, "gni": true }'

For any one who has ever tried to parse json in their liquidsoap scripts, this is gonna be a game changer. We have a detailed article here

Partial function application has been removed.

This is not so much an improvement but something we thought was an acceptable trade-off. Support for partial application is creating a lot of complexity in the language's implementation and not a lot of users are actively using it. This change means that instead of doing:

def f(x, y) =
...
end

g = f(0)

You will now have to do:

def f(x, y) =
...
end

def g(y) =
  f(0, y)
end

Regular expressions are now first-class entities.

This should be familiar to anyone used to working with Javascript's regular expression. So, now, instead of doing:

string.match(pattern="\\d+", s)

You will now do:

r/\d+/.test(s)

There's a detailed description of this new feature here.

Full Changelog:

2.1.0 (2022-07-15)

New:

• Added support for variables in encoders (#1858)
• Added support for regular expressions (#1881)
• Added generalized support for value extraction patterns (#1970)
• Added support for string getter for http.{post,put} operations (#1984)
• Added output.youtube.live.hls
• Rewrote out internal JSON parser/renderer (#2011). Breaking change values
  that cannot be represented as JSON will now raise error.json when
  converted to JSON. infinite and nan floats can be exported using the
  json5 export format.
• Added socket API (#2014).
• Added support for ffmpeg bitstream filters (#2387)
• Added liquidsoap.version.at_least.
• Added video.rectangle, video.persistence.
• Added video.vumeter.
• Added video.slideshow.
• Added video.add_text.camlimages (#2202).
• Added video.text.* and re-implemented video.add_text.* from those (#2226).
• Added irc.channel operator to retrieve the contents of an IRC channel
  (#2210).
• Added new in-house parsing of metadata for some image and video formats
  (#2236).
• Added file.download
• Added new options for %ffmpeg copy encoder: ignore_keyframes
  and wait_for_keyframe (#2382)

Changed:

• Removed support for partial application, which should avoid some type errors,
  improve performance and simplifies the code related to the reduction (#2204).
• Video dimensions (width and height) can now be specified per stream in the
  type and are then used instead of the default ones. For instance, you can now
  write

  s = (single("file.mp4") : source(video(width=300,height=200)))
  

  in order to force the decoding of a file to be performed at the 300×200
  resolution (#2212).
• Video images are now canvas, which means that they do not directly contain
  the images, but are constituted of multiple images placed at various
  positions. This should make much more efficient operations such as making
  videos from multiple ones, adding a logo, etc. (#2207)
• output.youtube.live renamed output.youtube.live.rtmp, remove bitrate and
  quality arguments and added a single encoder argument to allow stream copy
  and more.
• source.on_metadata and source.on_track now return a source as this was the
  case in previous versions, and associated handlers are triggered only when the
  returned source is pulled (#2103).
• Made streams_info parameter of output.file.hls a record (#2173).
• Disable scrolling by default in video.add_text. You can re-enable it by
  using video.add_text(speed=70, ...).
• Added "example" sections to operators documentation, we now need to populate
  those (#2227).
• Default implementation of video.testsrc is now builtin, previous
  implementation can be found under video.testsrc.ffmpeg.
• Images can now generate blank audio if needed, no need to add
  mux_audio(audio=blank(),image) anymore (#2230).
• Removed deprecated timeout argument in http.* operators.
• Deprecated request.ready in favor of request.resolved.

Fixed:

• Fixed typo in status command of the mix operator.
• Fixed performances issues with input.ffmpeg and input.http (#2475)
• Fixed list.shuffle which was used to randomize playlists in playlist
  operator (#2507, #2500).

Liquidsoap 2.0.7

This is the seventh bugfix release of the 2.0.x release branch of liquidsoap. We promised to only release new versions for this branch for important bug fixes and found two:

• A memory leak with the opus headers. Technically this is a bug in ocaml-opus but we also had to release new binary assets.
• An inefficient initialization of decoding buffer and samplerate converters

This release addresses those issues as well as a minor one with initial shoutcast/icecast metadata. It is intended as the last versioned released with potential follow-up being pushed as rolling releases on a best-effort basis.

The initial 2.1.0 liquidsoap release was also produced as a companion release to this one. All users are now advise to start exploring the 2.1.x release branch as we expect most if not all bug fixes to be only applied on this branch.

Happy liquidsoap hacking!

2.0.7 (2022-07-15)

Fixed:

• Fixed memory leaks with opus bindings.
• Make sure decoding buffer and samplerate converter are only created once. (#2475)
• Make sure first metadata is always sent in icecast/shoutcast output (#2506)

Liquidsoap 2.0.6

This is the 6th and last bugfix release for the 2.0.x branch. Following this release, the 2.0.x development branch will only be updated on a best-effort basis. New projects are now advised to work with the rolling-release-v2.1.x branch, will is set to be the next stable release.

This release contains a set of minor fixes. Production scripts using any 2.0.x version are advised to switch to it but, still, after testing that there is no unforeseen regression.

A lot of effort has been put into debugging memory-releated issues with regard to requests. If your script uses a lot of requests (playlist, request.dynamic etc.) you should benefit from upgrading to this version.

Full changelog:

2.0.6 (2022-06-20)

New:

• Added video/mp4 to list of recognized mime types for request resolutions.

Changed:

• Log errors when using process.read (##2420, @martinkirch)

Fixed:

• Memory leak when executing process.run (#2424)
• Delay harbor server endpoint registration until application has started (#1589)
• Print user-readable encoder parameter error report.
• Fixed m3u metadata parsing when artist has a comma in their name (#2449)
• Cleanup failed request in playlist operator.
• Make sure requests are always cleaned up, making request.destroy calls
  optionals.

Liquidsoap 2.0.5

This is the 5th bugfix release of the 2.0.x branch, fixing mostly minor issues. This is also the last stable release on this branch as 2.1.x is expected to be the next stable release cycle.

2.0.5 (24-05-2022)

New:

• Extended m3u EXTINF parser to support empty duration and annotations.

Changed:

• Brought back mix operator (#2401)

Fixed:

• Allow crossfade duration override of 0.
• Buffer synchronization issues.
• Drop methods from ffmpeg filter input source
  types to avoid unecessary conflicts.
• Fix evaluation of abstract values with methods.
• Prevent some sources from being consumed when not active,
  namely ffmpeg inline encoders, soundtouch, resample and all
  the muxing operators.
• Raise runtime exceptions in string.replace failures with
  useful message. (#2408)
• Prevent request.dynamic from raising exceptions when checking
  if the source is ready (#2381)
