JWL Helper is a Windows application which acts as a “companion” for JW Library to assist in displaying media at Kingdom Hall meetings.

- A command-line tool to easily merge JW Library backups, written in Go. For the iOS version, visit ios-jwlm. Go-jwlm allows you to merge two.jwlibrary backup files, while giving you control of the process - your notes are precious, and you shouldn‘t need to trust a program solving possible merge conflicts for you.
- Download this app from Microsoft Store for Windows 10, Windows 8.1, Windows 10 Mobile, Windows 10 Team (Surface Hub). See screenshots, read the latest customer reviews, and compare ratings for JW Library Sign Language.
JW Library is compatible with the following Apple devices. IPad 2 and newer (running iOS 9.0 or later) iPhone 4 and newer (running iOS 9.0 or later) iPod touch 5th generation (running iOS 9.0 or later). With option 2 however, please be aware that JW Library is a “Windows 10 App” which opens a separate “media window” which is visible on the Windows taskbar. If the operator (accidentally or otherwise) interacts with this “media window”, then the window parenting / focus / z-ordering can become a bit tempemental and you might find. One final note: according to MacRumors, via the Verge, it might be possible at the moment to use an app such as iMazing to copy an iOS app from your own phone or ipad to your mac, and then attempt to run it (even if the developer hasn't approved it, as I mentioned earlier)- it notes that this process could be blocked by apple in the future.
Main Features
- Simple interface optimized for touch-screen devices (mouse operation works fine too)
- Purely uses JW Library for all media and is not reliant on any external feeds or services
- Ability to display external media (images, videos and audio)
- Plays background music before/after meetings

Previous Releases
Version 1.0.7 (October 9, 2018)

* Implemented image “cross-fade” effect when transitioning between images.
* 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
* 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)
Download Jw Library For Mac
* Added support for AUDIO files (*.mp3, *.wav) to be played. They behave like video files – simply add them to the USER VIDEOS folder.
Jw Library Mac App Store Free
Fishdom h2o hidden odyssey. * 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.

In the SETTINGS file, under the [Settings] section, edit the Language=E line and set it to your language symbol.
