Hi 🙂
bbPress follows WordPress list here https://codex.wordpress.org/Embeds
Oh…. Look… You should be able to 🙂
Are you running WordPress with define('WPLANG', 'zh_CH');
in your wp-config.php
?
The WordPress language pack for zh_CH
includes the following code:
https://i18n.trac.wordpress.org/browser/zh_CN/tags/3.8.1/dist/wp-content/languages/zh_CN.php#L84
83 /**
84 * Youku wp_embed handler
85 *
86 * Embed code last updated:
87 * Wed, 06 Jun 2012 00:36:11 -0400
88 *
89 * Feel free to submit or correct URL formats here:
90 * https://cn.wordpress.org/contact/
91 *
92 * @since 3.4.0
93 */
94 function wp_embed_handler_youku( $matches, $attr, $url, $rawattr ) {
95 $embed = sprintf(
96 '<embed src="http://player.youku.com/player.php/sid/%1$s/v.swf" allowFullScreen="true" quality="high" width="480" height="400" align="middle" allowScriptAccess="always" type="application/x-shockwave-flash"></embed>',
97 esc_attr( $matches['video_id'] ) );
98
99 return apply_filters( 'embed_youku', $embed, $matches, $attr, $url, $rawattr );
100 }
101 wp_embed_register_handler( 'youku',
102 '#https?://v\.youku\.com/v_show/id_(?<video_id>[a-z0-9_=\-]+)#i',
103 'wp_embed_handler_youku' );
So as you should be able to have this in WordPress posts and pages etc that ‘should’ flow on down to bbPress to allow you to use youku 🙂
