FlowPlayer
==========
FlowPlayer is a video player for FLV. It is designed to be
embedded into an HTML page. FLV is handled using 'progressive download' with
Flash's NetStream and NetConnection classes. FLV is supported with Flash Player
version 7 or higher.
Version history
===============
0.9 Initial public release. All basic features are in place.
0.9.1 Added 'autoPlay' variable that can be used to specify whether the
playback should begin immediately when the player has been loaded into
the Web browser.
0.9.2 Bug fixes.
0.9.3 Added new 'bufferLength' variable that can be used in the HTML page to
specify the length of the buffer in seconds when streaming FLV. Fixed a
bug that prevented playback after an FLV was completely played.
0.9.4 Added a 'baseURL' variable that can be used to specify the location of
the video file to be loaded by Player.swf. See Player.html for an
example.
If the 'videoFile' variable's value contains a '.flv' or '.swf'
extension, the standalone player (Player.swf) will NOT append this based
on the detected flash version. If a prefix is not present, the player
always appends either one of these prefixes.
1.0
- Displays a "BUFFERING..." text when filling the video buffer.
- Fixed playback of the start and the end of the video where the player
was errorneously cutting off some of the video.
- Added a new start() function to the FlowPlayer class.
- Fixed Sample.fla
1.1
- Added ability to loop; Contains a new toggle button to control looping.
Default looping state is defined in 'loop' parameter. Thanks Jeff Wagner
for contributing the initial looping support.
- Now resizes according to the size defined in the HTML page
- Fixed some flaws in the graphics
- The color of the progress bar is now gray by default (more neutral). The
color can be customized by parameters.
- Removed support to play videos in SWF format.
1.2
- Added a 'autoBuffering' option and welcome image support.
- Added a 'hideContols' option to hide all buttons and other widgets and
leaving only the video display showing.
- Added support for welcome images
- Most of the UI is now built dynamically with ActionScript instead of using
pre-drawn images. This results in 50% smaller download size.
1.2.b2
- Fixed binary build that contained an old buggy FlowPlayer.swf
1.3
- Fixed resizing problem that occurred with Internet Explorer: The video was
not resized when the page was refreshed.
1.4
- Removed the blue the background color of the player. The light blue color
became visible when using only the obect-tag to embed the player into a page.
By using only the object tag it's possible to author valid XHTML. The sample
FlowPlayer.html now shows this kind of markup.
1.5
- Support for playlists
- Extenal configuration file that enables configuring all the existing
settings. All settings defined in this configuration file can be
overridden using flashvars in the HTML object tag.
- Basic skinning support: Images for all buttons (play, pause, looping
toggle, and dragger) can be loaded from external JPG files. Smaller
versions of the default buttons are provided as an example.
FlowPlayerLiht.swf is meant to be used with skinning: it does not contain
any button images in itself and therefore is slightly smaller in download
size.
- 'hideBorder' option
- visual improvement of control buttons
- dragging can be now done by clicking anywhere in the progress bar area
- clicking on the video area pauses and resumes playback
- scaling the splash image is now optional. Alternatively it can be centered
into the video area.
- removed the border surrounding the video area
- plus some more minor changes
Bug fixes:
- Seeking using the dragger button is more accurate. Now it is possible to
seek to the very beginning of a clip.
1.6
Bug fixes:
- Does not buffer unnessessarily if looping through one clip again and again
- Playback can be started normally again when the clip is done and looping
is off. There was a bug that prevented this.
- Clicking on the video area did not start playing if splash not used and
when autoPlay=false
- The seeker button aligned to the right from the mouse position when it was
grabbed using the mouse button. Now it stays on the same position it was in
when the mouse button was pressed down.
- It was not possible to use characters 'y' and 'Y' in the names inside
the playList. Now following characters are available:
"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz?!/-:,. 1234567890"
1.7
Fixes:
- baseURLs are not appended to file name values that are complete URLs
- minor visual enhancements
New features:
- Support for long videos: Initial support for streaming servers (tested with red5) +
thumbnails corresponding to cue points.
- Video duration and time indicator
- Resizing of the video area through a menu
