Radiant Media Player has always been an HTML5-first web media player. When we started development of Radiant Media Player in late 2014 it made sense to add an advanced Flash fallback providing a unified API between HTML5 & Flash. As Flash becomes widely deprecated in the industry we will progressively phase out Flash of our player. This is a good thing for everyone.
On an advertisement point of view on January 4, 2017 Google announced the end of Flash support in the IMA SDK by June 1, 2017. They leave this note:
Over the past few months we have seen a significant drop in Flash usage by Radiant Media Player customers. In Q4 2016 Flash only represented 10% of the traffic we saw through our player - we expect this to rapidly fall under 5% in 2017.
Following Google lead Radiant Media Player 4 will gradually stop supporting Flash with the below schedule:
Video ads through the Flash Google IMA SDK are still available (player version 4.5.8+) in Radiant Media Player 4 Flash fallback but as the Flash Google IMA SDK becomes deprecated we cannot guarantee they will continue to work or provide support for using them. Essentially VAST3, VAST2, Flash VPAID and VMAP tags should be supported.
We have ported a lightweight version of Radiant Media Player 3 Flash fallback into Radiant Media Player 4. Supported features for this lightweight Flash fallback are limited to essential player features. This is mainly provided to support HLS streaming with legacy Desktop browsers - mainly Internet Explorer 11 on Windows 7 (those legacy browsers do not support Media Source Extensions or native HLS streaming so HLS to Flash is the only option left).
For HLS on-demand streaming we still recommend to provide a MP4 progressive download URL alternative to the player so that we can avoid Flash all together.
Make sure to comply with cross-domain policy for HLS streaming to Flash to avoid common playback issues
All other player methods are not available with Radiant Media Player 4 Flash fallback. Refer to our player API documentation for details about the above API methods.
Only one skin is provided for Radiant Media Player 4 Flash fallback. It cannot be customised.
Refer to our general player settings docs for details about the above settings.
Video ads support in Flash include VAST 2 & 3, VPAID 1&2 & VMAP. Refer to our video ads docs for details about the above settings.
Our Flash video ads implementation is based on the deprecated Flash IMA SDK v3 - since this has been deprecated by Google on July 5, 2017 we cannot guarantee support for Flash video ads.
The following settings only apply to Radiant Media Player 4 Flash fallback:
flashFallBack: Boolean - enable or disable flash fallback - default: true
flashWMode: String - set Flash Window Mode, possible values are 'window', 'direct', 'opaque', 'transparent', 'gpu' - default: 'direct'
flashHlsMinbufferlength: Number - minimum buffer length in seconds that needs to be reached before playback can start (after seeking) or restart (in case of empty buffer). If set to -1 some heuristics based on past metrics are used to define an accurate value that should prevent buffer to stall - default: -1
flashHlsLowbufferlength: Number - low buffer threshold in seconds. When crossing down this threshold, HLS will switch to buffering state, usually the player will report this buffering state through a buffering statement. Playback may still continue - default: 3
flashHlsMaxbufferlength: Number - maximum buffer length in seconds. The player will try to never exceed this value for its buffer - default: 60
flashHlsCapLevelToStage: Boolean - this setting limits bitrates usable in auto-quality by the stage dimensions (width and height) - default: true
flashHlsCaplevelonfpsdrop: Boolean - this setting causes an automatic level switch down when frame rate loss is considered too high by player - default: true
flashHlsStartFromLevel: Number - from 0 to 1, indicates the preferred initial bitrate - default: -1
flashHlsAutoStartMaxDuration: Number - max fragment loading duration (bandwidth test + fragment loading) in automatic start level selection mode (in milliseconds) - default: -1
