No. JWL Helper is only available as a Windows application.

Q. What about the Dec 2017 letter recommending JW Library?

The letter “recommends” that JW Library be used as the media player.
JWL Helper in no way usurps or replaces JW Library, in fact it requiresJW Library and runs alongside it as a companion application.
It is noteworthy that JW Library is (at present) unable to display external images or video files. If a public speaker wishes to display his own images as visual aids for example, then there is no choice but to use another program. JWL Helper handles this.
In summary, the purpose of JWL Helper is to assist JW Library by providing an accessible and easy-to-use interface for displaying media from JW Library, as well as adding the ability to show external images / videos.
Of course, it’s up to each congregation to decide what’s best in their case.

Q. What about the JW Library License Agreement / Terms of Use?

That’s a good question, which is addressed in this forum post.

Q. Can I make a donation towards the development costs?

Thank you… that’s very kind, but not necessary. As an alternative, please feel free to make a donation here ?

Previous Releases

Library
Version 1.0.7 (October 9, 2018)
* Implemented image “cross-fade” effect when transitioning between images.
Fnaf song piano letters. * Improved monitor display handling. JWLH now uses lower level functions to extract the names of available displays rather than just “DISPLAY 1” etc.
* Improved JW Library compatibility code (again!) to try to eliminate the issue when the JW Library fails to come back to the front after displaying a video.
* BUG FIX: PDF handling now works correctly and PDF documents are correctly shown on the IMAGES tab.
Version 1.0.6 (August 13, 2018)
* Added a new “Copy to Clipboard” function when right-clicking on a media button. This copies the source media file to the Windows clipboard, allowing you to copy it elsewhere (e.g. if you have a second school with an independent screen and need to display media from a memory stick).
* Added some date sorting code in case midweek/weekend meeting days are in an unusual order Cs4 compatible with el capitan.
* BUG FIX: Fixed an issue with the parser which was loading all referenced “jy” media for w/b August 13.
Version 1.0.5 (August 6, 2018)
* Auto-update check – JWL Helper will now notify you (via a Windows 10 notification) when a newer version is available.
* Custom REMINDERS – you can now specify a reminder to be shown when a video starts and/or finishes. For example, if live streaming the meeting via OBS, the operator can be reminded to switch the stream over to the video output when a video starts, and then back to the platform camera once the video finishes.
To accomplish this, there are two new settings which can be added to the INI file under the [Settings] section :-
Reminder_OnVideoStart=A reminder to show when a video starts
Reminder_OnVideoFinish=Another reminder prompt for when the video finishes
* “Right-click -> Delete” from JWL Helper could fail because the user media file might be “locked” by JWL Helper. This release attempts to workaround that.
* Some more improvements to the JW Library compatibility (still trying to resolve those odd occasions when the JWL media window refuses to come back on the media display).
Version 1.0.4 (July 27, 2018)
* Added support for AUDIO files (*.mp3, *.wav) to be played. They behave like video files – simply add them to the USER VIDEOS folder.
* Improved “JW Library compatibility“. Sometimes the JWL media window wasn’t coming back to the front after playing a video. Hopefully this should be resolved.
