I would like to see webm video format to be possible to upload and embedded via media wysiwyg editor's upload feature.
We need to use hook_file_mimetype_mapping_alter() to add support for mkv and webm. We also need to ensure this is added to core as well.
Core issue filed for mkv and mka: #1293140: Add support for mkv and mka file extensions.
Added support for mkv and mka in file_entity and media:http://drupalcode.org/project/file_entity.git/commit/5bf88b8http://drupalcode.org/project/media.git/commit/fb71e88
I'm postponing support for webm as its an ambiguous as it could be either audio or video.
Have looked up and Apache has officially add webm and weba as video and audio respectively.
This has now been committed for weba and webm as well.
