Add tiddler types for audio and video

[braykov]

Current TiddlyWiki tiddler types contain Text and Image formats, but no audio or video.
Add these for easier embedding of music and video.

Hi @braykov there are actually two separate layers at which different content types can be registered within TiddlyWiki:

• The boot kernel defines the low level file types that TiddlyWiki understands - see them here. A type being defined here tells TiddlyWiki whether to treat it as binary or text, for example
• The core UI defines tiddlers for each tiddler type that is to be selectable in the "type" dropdown in the edit template - they are defined here

Are all the file types that you are interested in included in the first list?

There's a strong reason to keep the size of the dropdown reasonably small; we don't want users to have to scroll to see the entire list. So I think we should restrict it to the types that are commonly used, in particular the types that are commonly worked with interactively. Users can still manually type other types.

Creating _canonical_uri tiddlers manually is tedious in any case; I'd be quite interested in adding a special new UI for creating them.

I am particularly interested in audio/mp3,mp4,ogg. They are all included in the first group.
If I had to choose a single type, that would be .ogg.

hmmm. While the .ogg format is the one, that imo fits best to the TW project, because of its "free nature", its the one, that's the least known type.

IMO .mp3 is the de-facto standard and was the matter of a lot of copyright problems. Hence the .ogg format was created. ... but according to wikipedia

In Europe mp3 is patent free and in the United States, the technology will be substantially patent-free on 31 December 2017

So there should be no problem, to implement them. .. But imo the "best audio" format discussion is a "hot" topic. If we support one extension, we basically need all of them.

@Jermolene is it possible to include additional file extensions as plugins?

This would also solve a lot of problems with other file types, that are often requested. Users can decide, what's important for them, so the dropdown list and the core can be small, and we don't need to carry things around, which we don't use often.

👍 => "everything is a tiddler"

Yes, indeed, such a plugin would just contain tiddlers such as $:/language/Docs/Types/video/ogg, see the core types for the fields required.

The boot kernel defines the low level file types that TiddlyWiki understands:

new location
you can search for registerFileType or text/plain to find the code lines.

do i understand this correct that video/webm is currently not supported?
(as it is missing from the core list)
woud be nice for some local videos..

if i try it i get this message

Trying to load external content from file:///home/stefan/xyz//VID_20190422_203909.webm

If this message doesn't disappear, either the tiddler content type doesn't match the type of the external content, or you may be using a browser that doesn't support external content for wikis loaded as standalone files. See https://tiddlywiki.com/#ExternalText

Hi @s-light we currently add file types to the boot kernel list as they are requested by users. It looks like we've currently got webp images, but not webm videos. It would be great if you would like to prepare a PR? See our contributing.md file for guidelines.

[s-light]

thanks @Jermolene - i will try the PR - but will need some weeks to get to it ;-)

[s-light]

@Jermolene i have created the PR.
hope that it is all fine as i have done it.

[Jermolene]

Thanks @s-light

[s-light]

as i see it this issue is fixed.
from what i have seen i think all mayor file types for audio & video are supported..
so this could be closed?! @braykov

[Jermolene]

I think we can indeed close it for now. Please open a new ticket to request any further new types.
