As the title says. #20 #22

Basic Media Player has been implemented in models branch.

Todo:

• Basic Player
• Creation Name
• Enhanced Play Button - Play/Pause and allow replaying
• Elapsed Time
• Total Time
• Time Scrubber
• Mute Button (and/or Mute Slider?)

Example from Oracle on implementing Media Player with controls: Link

As the title says - possibly because I'm running in java 8

Reduce likelihood of breaking file paths if the file structure is changed in the future

• Figure out creation structure
• temp files

We need to add image previewing in between snippets and naming
Requirements:

• Extra page for previewing
• In between chunkView & nameView
• Lazy loading of 10 images when the wikipedia search is first pressed
• Drag and drop to rearrange
• Up/Down buttons
• Delete image
• Retain order
• Figure out how many images to download - default to 10?

As the title suggests - it may be a good idea to cache searches in case they come up again

Fully implement CreationBuilder.build() to create Creations

Tasks:

• Implement CreationBuilder with CreationManager
• Determine File Structure. See #20
• Download images. See #19
• Implementation for combining
• FFMPEG calls - combine audio chunks, images and search term. Potentially use this wrapper for FFMPEG - import into Gradle using JitPack
  • audio chunks combined
  • duration of audio
  • ffmpeg slideshow
  • combine slideshow and audio
  • search term overlay on slideshow
• Progress updates. Ideally progress bar in Creations ListView

Implement Popups for:

• Deleting a creation
• Cancelling the creation process
• More than 40 words selected

Would be nice for the user to be able to stop a previewing and playing back a chunk.

• Tell markers how to run the jar
• Which machine it runs on
• import gradle project if they want to compile it themselves
• run fatJar to make the jar
• need to chmod the jar with executable
• Write a script to execute the jar?

Load saved creations from files

If a single creation is deleted the video player view is not returned to the main menu

Proposed solution: Implement MediaPlayer as field on ChunkView

I'm currently on java 8 & I built all the fxml scenes in scenebuilder 8. However, recent commits have changed the fxml version to 11

Similar to #21 and #11 - the audio creation process needs to be streamlined

• Selecting voices
• Festival config
• espeak config
• Implementation for festival
• Implementation for espeak

Similar to #24 - we need to make sure that we can handle files with spaces - either remove spaces, disallow them, or replace with _

Add the following line to .scm for saving:

(Parameter.set 'Audio_Required_Rate 22050)

NullPointerException thrown. Apply check for null MediaPlayer for Preview Al

Refactor ChunkView to include Synthesizer settings as dropdown menus

For the Snippet/Chunk ListView, if an item is dragged onto an empty area of the ListView, the item will vanish when dropped.

Requirements:

• Flicker4Java API (via Nasser)
• Allow user to choice how many images to use - no greater than 10
• API Key
• Image downloading
• How to store the downloaded images

Related to #39 - after creating a creation it doesn't show up to play

Enhance Video Player (See #7):

• Implement Icons for Play Button and Mute Button
• Implement Icons (Views, Rating, Duration) for Creation ListCell's

Related to #20

• Serialize CreationList
• "Self-healing" serializable
• (optional) Editing

Not working properly. Likely due to garbage collection. Proposed solution: Re-implement using tasks and fields.

It seem that using Gradle to manage the API Keys locally and include them into the build files is the best solution:

• https://stackoverflow.com/questions/35722904/saving-the-api-key-in-gradle-properties
• https://www.learnhowtoprogram.com/android/web-service-backends-and-custom-fragments/managing-api-keys
• How to store the API keys so that markers can use it - they don't want to edit code other than to possibly to add their own API keys to a text file. See properties or gradle or more gradle. Another one - see #25

Enable correct asynchrony with Manager

Implement thumbnail, name, duration similar to here

Implement calls directly from MediaWiki API

I'm thinking that a way we could track user retention would by marking creations with tags that track how many times it has been played, and then user rated confidence levels also.

Implementation-wise this would likely extending the comparators used in the creation list, allowing to sort by confidence/least amount played

Implement Alex's Wikit Task from Assignment 2

As per the title

Maori words with macrons won't be enunciated properly in festival (as festival has no macron support). Might be a good idea to clean input strings

• TextArea - editable
• Chunk creation
• Audio preview
• Audio saving
• Chunk Preview - Audio
• Synthetic speech settings
• All chunks playback
• Chunk limit? (20-40 words)

Fxml is kinda janky on higher-res displays

We nees to figure out how to create a runnable jar with gradle

Currently implemented as models.Synthesizer using Espeak for preview and saving

Requirements (from A3 brief):

For each chunk of selected text the user should be able change the synthetic
speech setting ( e.g. change voices, or change speech synthesizers)

Significant refactoring will be required to implement both Espeak and Festival as well as options for voices and speed. Suitable solutions may involve an Abstract Synthesizer or builder pattern.

Plan:

• Abstract SpeechSynthesizer - preview(), save()
• Concrete EspeakSynthesizer and FestivalSynthesizer - immutable
• Settings: Voice, Speed, Pitch?
• Builder/Factory to use with Synthesizer settings box. Radio buttons for Espeak/Festival. Dropdown for voices. Slider(?) for speed

Need a clear method on singleton ChunksManager
