I think i ggot it:
Filters ‘bbp_get_topic_content’ and ‘bbp_get_reply_content’. They MUST run after wpautop, so i gave them priority 1000.

All of my code to get my plugin compatible with bbpress looks now:

/* We use bbPress */
// editor bbpress in tinymce mode
function wppa_enable_visual_editor_in_bbpress( $args = array() ) {
	
	if ( wppa_switch( 'photo_on_bbpress' ) ) {
		$args['tinymce'] = true;
		$args['teeny'] = false;
	}
    return $args;
}
add_filter( 'bbp_after_get_the_content_parse_args', 'wppa_enable_visual_editor_in_bbpress' );

// remove insert wp image button
function wppa_remove_image_button_in_bbpress( $buttons ) {
	
	if ( wppa_switch( 'photo_on_bbpress' ) ) {
		if ( ( $key = array_search( 'image', $buttons ) ) !== false ) {
			unset( $buttons[$key] );
		}
	}
	return $buttons ;
}
add_filter( 'bbp_get_teeny_mce_buttons', 'rew_remove_image_button_in_bbpress' );

// enable processing shortcodes
function wppa_enable_shortcodes_in_bbpress( $content ) {

	if ( wppa_switch( 'photo_on_bbpress' ) ) {
		$content = do_shortcode( $content );
	}
	return $content;
}
add_filter( 'bbp_get_topic_content', 'wppa_enable_shortcodes_in_bbpress', 1000 );
add_filter( 'bbp_get_reply_content', 'wppa_enable_shortcodes_in_bbpress', 1000 );

Pleas be so kind to review this to see if i did it right or did oversee something.

We want to see:

Yes, in the content of the topic/reply. It makes from [photo 123] the html to display photo with id=123 from plugin wp-photo-album-plus – instead of a photo from the wp media library – according to the settings in the settings page of that plugin; e.g link to lightbox, subtitle and possible social media buttons to share the image.

The button that opens the dialog to select the photo, and optionally upload a new one, is now working without mods to bbpress, but it shows ‘[photo 123]’ instead of the picture. If the content would be filtered by the standard wp content filters, it would display the image, like it does in a wp native page or post.

Thank you, this works great!

One thing left: i can not find the filter to filter forum posts/replies, so i could do:

function my_process_shortcodes($content) {
  return do_shortcodes($content);
}
add_filter( '...??...', 'my_process_shortcodes' );
