Subtitle player extension for chrome

Add subtitle overlay from SRT files to any video element, with options to sync the subtitle.

Note:

1. To install dependencies run npm install
   All files with *.bundled.* extension are generated dynamically by running npm run build and they are not included in the repo.

2. A symlink in node_modules\lib pointing to src\lib is required for imports in .js files (generated under windows, i.e. it may not work on your system)

TODOs:

• add linting scripts
• global log to log errors (window.onerror)
  • global log in main scripts (contentscript and popup)
  • global log in components
• redirect all log messages to bg page
• add indicator while searching or downloading a subtitle
• add watch mode in npm
• show limit for downloading subtitles from OpenSubtitles.org
• use setUninstallURL to clear storage
• use chrome.runtime.getBackgroundPage instead of messaging
• auto suggest file name from page info (done: page title as placeholder)
• add error reporting mechanism (maybe StackTraceJS or jsErrLog)
• consider using TextDecorder instead of FileReader for local file upload
• resize subtitles with mouse
• reposition subtitles with mouse
• use other key for subtitles saving since all youtube videos have the same video source! (fixed: now using location.href + video.currentSrc)
• stop searching if other script on the same page has already found a video (done using communication with bg)
• show some indicator when changing size even if no current subtitle is visible
• unintuitive size controls
• use MutationObserver to detect video instead of an interval (not working)
  • check if it can detect changes in iframes and in that case give all_frames manifest option
  • no need for site specific scripts but specific selectors
• push subtitle up if video controls are visible (site specific)
  • youtube
  • netflix
  • general (default controls)
  • smooth controls movement when pushed
• style subtitle container to match video style (using MutationObserver)
• disable color picker if no subtitle is activated (add as an event listener for sub-deactivated)
• random number of subtitles (right now fixed to three)
• add option to unload all subtitles
• use template for subtitle panes in html (b/s they are almost the same but some ids and data-subtitle-index are different), solved using mustache
• consider using webpack
• show if subtitle is loaded on the video (specially if from cache and maybe give the option to unload it)
• resize subtitle if width > video width (fixed by setting subtitleContainer width to match video)
• save playing position before close (use chrome.tabs.onRemoved.addListener)
• customize eslint options
• change size and position when video resizes
• delete old loaded subtitle when choosing new one
• subtitle size relative to video size
• if a subtitle is uploaded disable up choose file button
• remove current subtitle and enable choose file button
• drag and drop to add subtitle file (maybe replace old one)
• spinner while searching for a video and show results (even if not found)
  • Note: this requires knowing how many frames (i.e. content scripts) there are in the current active tab and the fact that all of them couldn't detect any video in their corresponding document element
• auto search for subtitles
• disable search for video if one found
• hide sync controls if no subtitle is active (found video + uploaded srt) Solution: disabled if no subtitle is active
• options page for some subtitle controls (such as style, subtitle databases, ...)
• subtitle controls on video itself (instead in popup)
• other languages (unicode) support
• raise subtitle if video controls are visible
• save subtitle when open page again, so no need to reload the subtitle (using chrome.storage)
  • save sync value and reapply it
  • save detected file encodings info and show them on start
• option to manage (show/update/remove) all saved subtitles
• keyboard to control video playback
  • add options for customizable keys such as modifiers
  • option to always register on this page (save in chrome.storage.local)
  • better way to show seeked amount after pressing a key (right now in subtitle!, see youtube style with arrows)
• auto detect file encoding (using charset-detector and browserify)

Performance:

• add subtitle containers only when needed (right now the 3 of them are added always when a video is found)

Extend subtitle controls

• reset subtitle sync
• sync range input
• change file
• disable
• style control (maybe in css)
  • font size
  • font color
• global style controls
  • font size
  • allow reposition with mouse

Learn mode

• multiple languages at the same time
• adjust subtitle width according to the number of enabled subtitles

Bugs

• if subtitle file input is disabled then label must also be disabled
• can't override video in webkit-fullscreen mode -> can't show subtitle container/holder divs
