• Added advanced FFMPEG/LIBAV encoding options. New options include choice between Constant Rate Factor and Average Bit Rate, H.264 profiles and levels, audio bit rate, disabling nice on Linux, and the ability to encode with more than one thread.
• Added -movflags faststart option available in newer versions of FFMPEG/LIBAV, eliminating the need for qt-faststart or MP4Box.

• Split plugin settings page in to two tabs.
• Fixed saving plugin settings when multiple settings are changed rapidly.
• No longer starting video encodes using nohup command on Linux servers.
• FFMPEG vpre flag switched from slow to fast.
• Enabled actual support for encoding with libfdk_aac, and the experimental built-in aac encoder as a last resort.
• Fixed cases where the encode queue would not advance if an unexpected error happened.
• Fixed encoding library messages so the errors are saved to the encode queue and don't disappear immediately.
• Changed endOfVideoOverlay and endOfVideoOverlaySame options to lowercase.
• Revised method for determining if a video URL refers to an attachment in the WordPress database to account for differences between urls using http and https and filenames that slip into the database with spaces intact.

• June 30, 2013 =
• Updated Video.js to version 4.1.0
• Restored code to show captions and download links in gallery pop-ups.
• Fixed conflict with fitVids.js by disabling the function whenever a video is embedded with the KGVID shortcode. fitVids.js is not compatible with the Video.js player and is not necessary to make videos responsive when you are using this plugin.
• Increased bitrate of encoded videos.
• Increased play button circle thickness and triangle size.
• Made video title overlay background slightly transparent and the title width fluid through CSS rather than JS.

• May 30, 2013 =
• Updated Video.js to version 4.0.3 which includes fixes when hitting esc to exit fullscreen that this plugin had previously dealt with through additional JavaScript.

• Moved play button overlay behind gallery thumbnail title if they happen to overlap.
• Changed WordPress user capability required to access plugin settings menu page from 'administrator' to 'manage_options' to allow access to multisite Super Admins and anyone else who has the manage_options capability.

May 25, 2013 = * Updated Video.js to version 4.0.2 which is supposed to solve IE play-button loading issues. * Added option to show image at end of video in Video.js player (similar to the feature already available in Strobe Media Playback). * Fixed bug that ignored gallery_id setting in gallery shortcodes and was preventing gallery_include setting for videos that are not children of the current post. * Brought download link into shortcode rather than old method of inserting it into the post as text below the shortcode. * Automatically adjust pop-up gallery window height to display captions, view counts, and download links. * Rolled back responsive video resize method. Only the width of the immediate container will be used to calculate the correct size. * For very small videos, Video.js controls are now selectively removed as the width drops below 260 pixels to prevent them from dropping outside of the video window.

May 23, 2013 = * Changed check for FFMPEG to use the H.264 sample video as input to avoid any PNG-related red herrings. * Added -f mjpeg to thumbnail-generating command to maintain compatibility with versions of FFMPEG that can't figure it out on their own.

May 21, 2013 = * Removed second argument from json_encode() which caused video setup & resizing features to fail when servers were running PHP 5.2.

May 19, 2013 = * Updated Video.js to version 4.0 and created a new skin that approximates the old one. Older versions of Video.js had some security holes, so this update is highly recommended. * Significantly reduced inline JavaScript generated by the plugin. * Fixed bug that disabled Strobe Media Playback player and caused "TypeError: Error #1034" messages, particularly in Internet Explorer. * Fixed bug that caused view count to be replaced by complete views when the end of the video is reached. * Fixed bug that disabled video encode status monitoring in media modal popup when the same video was already in the post edit window. * Fixed missing "document." in JavaScript when choosing thumbnails which prevented some users from properly selecting and saving generated thumbnails. * Fixed bug that displayed WordPress thumbnail-sized poster image if no poster URL was in shortcode. * Tweaked video resize method to support more kinds of themes. * Added ability to turn off watermark on individual videos by entering watermark="false" in the shortcode. * Added option to disable embedding on other websites. * Added option to allow videos to be placed next to each other on the page. * Added support for AAC library libfdk_aac. * Adjusted embedded video and gallery CSS to account for colored backgrounds. * Renamed "Poster image" plugin setting to "Default thumbnail" * Removed post meta box below post editing window until I can work out a way to generate them without disabling video encode status monitoring in media modal popup when the same video is already in the post edit window. * Replaced deprecated ereg PHP function with preg_match and used a more precise regular expression when determining the height and width of videos.

• May 01, 2013 =

• Added options to display video title and embed code overlays on video player, and captions and view counts below videos.

• Redesigned settings page to save using AJAX, and added a sample video player so changes are seen immediately.
• Added iframe method to embed your videos on other websites.
• Additional video formats encoded by the plugin are now added to the WordPress database as video attachments. To avoid a Russian nesting doll scenario these child attachments do not have the fields for creating thumbnails and encoding additional formats.
• Changed encoded H.264 extensions from .m4v to .mp4 to increase compatibility with WordPress 3.6's new video capabilities. Existing M4V files will still work.
• Checks only one time for alternate video sources when videos are embedded from other servers. This should speed up page load times considerably.
• Added ability to rotate and replace the original file for videos recorded vertically on cell phones.
• Added post meta box to posts with embedded videos that lists alternate formats found for each video.
• Added option to set a post's featured image to the most recently generated thumbnail, and a button to set all previously generated thumbnails as featured images.
• Added option to save generated thumbnails as children of either the video or the post the video is attached to, and a button to convert all thumbnails to the chosen hierarchy.
• Added option to delete associated thumbnails and additional encoded video formats when original video attachment is deleted.
• Added backwards compatibility for WordPress versions 3.2 and above.
• If Strobe Media Playback player is selected, the Video.js player is used in situations where Flash doesn't work (webm, ogg playback) instead of the ugly default browser players.
• Added watermark, view counts, volume attribute, and Google Analytics event tracking when using Strobe Media Playback player.
• Added alignment option to center or right-justify videos.
• Revised video player setup to properly resize the player if the containing DIV is smaller than the video, and resize again if the window size changes (or orientation changes on Android).
• No matter which player is selected, iOS now displays the built-in controls so AirPlay works.

• Fixed endless "loading" spinner shown at the end of videos in some browsers in Video.js player.
• Clicking "Insert into post" immediately after upload without changing any options now inserts shortcode instead of just the title of the video.
• Inserting shortcode without a thumbnail no longer attempts to save the nonexistent thumbnail. Thumbnail cleanup is handled better.
• Fixed error message "array_key_exists() expects parameter 2 to be array" when shortcode didn't have attributes.
• Escaped all shell commands for increased security.
• Fixed bug that made "Encode" button disappear if all formats were checked.

• Changed method for determining if a video has been played or paused and played again, for counting purposes.
• Fixed check for mime type when generating H.264 video encode checkboxes to avoid showing options for QuickTime files that are higher resolution than the original video.

• January 29, 2013 =
• Fixed bug that added a blank line to JavaScript embedded in the page if "volume" wasn't set in the short code (Video.js only).
• If video player is set larger than the containing DIV and the player size is reduced to fit, the height is now rounded to the nearest integer.

• January 24, 2013 =
