New description:
This ticket is about adding support for creating Ogg Theora or WebM videos
from animation objects. The resulting video files are embedded into the
notebook using the HTML 5 video tag.
The show method of animations now works more like the one of Graphics
objects. Animations can now be embeddend in html fragments, for example
using html.table(). By default animations are still created as animated
GIFs. To get a modern video from an animation "a" use one of these:
{{{
a.show(mimetype="video/ogg")
a.show(format="webm")
}}}
The original ticket was designed to use libtheora and libogg from #7297
and only supported Theora. The currently attached branch builds on FFmpeg
and supports a variety of formats, including Theora and WebM. Support for
calling FFmpeg is already in place, so the focus here is on user
interface, mainly integration with the `show` method and using HTML 5
video tags.
