static core_media_player_native::add_attributes ( $tag,
$attributes )
staticinherited

Adds attributes to the media tags.

Parameters
string$taghtml tag which properties are extracted, for example "<video ...>....</video>"
array$attributeskey-value pairs of attributes to be added
Return values
string

◆ compare_by_rank()

static core_media_player::compare_by_rank ( )
staticinherited
Deprecated
since Moodle 3.2

◆ embed()

media_videojs_plugin::embed ( $urls,
$name,
$width,
$height,
$options )

Generates code required to embed the player.

Parameters
moodle_url[]$urls
string$name
int$width
int$height
array$options
Return values
string

Reimplemented from core_media_player.

◆ find_language()

media_videojs_plugin::find_language ( )
protected

Tries to match the current language to existing language files.

Matched language is stored in $this->language

Return values
stringJS code with a setting

◆ get_attribute()

static core_media_player_native::get_attribute ( $tag,
$attrname,
$type = PARAM_RAW )
staticinherited

Extracts a value for an attribute.

Parameters
string$taghtml tag which properties are extracted, for example "<video ...>....</video>"
string$attrnamename of the attribute we are looking for
string$typeone of PARAM_* constants to clean the attribute value
Return values
string|null

◆ get_embeddable_markers()

media_videojs_plugin::get_embeddable_markers ( )

Lists keywords that must be included in a url that can be embedded with this player.

Any such keywords should be added to the array.

For example if this player supports FLV and F4V files then it should add '.flv' and '.f4v' to the array. (The check is not case-sensitive.)

Default handling calls the get_supported_extensions function, so players only need to override this if they don't implement get_supported_extensions.

This is used to improve performance when matching links in the media filter.

Return values
arrayArray of keywords to add to the embeddable markers list

Reimplemented from core_media_player.

◆ get_language_content()

static media_videojs_plugin::get_language_content ( string $lang)
