Methods

convertCodecs(contentType, mimeType) → {string}

For any stream, convert its codecs to MP4 codecs.
Parameters:
Name Type Description
contentType string
mimeType string
Source:
Returns:
Type
string

findTransmuxer(mimeType, contentTypeopt) → {shaka.extern.TransmuxerPlugin}

Parameters:
Name Type Attributes Description
mimeType string
contentType string <optional>
Source:
Returns:
Type
shaka.extern.TransmuxerPlugin

findTransmuxerPlugin(mimeType, priorityopt, nullable) → {shaka.extern.TransmuxerPlugin}

Finds a plugin registered for |mimeType| without instantiating it or calling isSupported(). Used by the worker where MediaSource may not be available to validate support. When |priority| is null (default), returns the highest-priority plugin. When |priority| is specified, returns the plugin at that exact priority or null if none is registered at that level.
Parameters:
Name Type Attributes Default Description
mimeType string
priority number <optional>
<nullable>
 null
Source:
Returns:
Type
shaka.extern.TransmuxerPlugin

findTransmuxerPluginPriority(mimeType, plugin) → {number}

Returns the priority at which |plugin| is registered for |mimeType|, or null if it is not registered for that type. A worker cannot share plugin identity with the main thread, but it shares the registrations, so the priority is what tells the worker which plugin the main thread chose. If the same plugin is registered at several priorities, the highest is returned, which is the one findTransmuxer probes first.
Parameters:
Name Type Description
mimeType string
plugin shaka.extern.TransmuxerPlugin

Returns:
Type
number
