Video Output Types#

This module defines the rich output types for video formats.

class sage.repl.rich_output.output_video.OutputVideoAvi(video, loop=True)[source]#

Bases: OutputVideoBase

AVI video

EXAMPLES:

sage: from sage.repl.rich_output.output_catalog import OutputVideoAvi
sage: OutputVideoAvi.example()
OutputVideoAvi container

>>> from sage.all import *
>>> from sage.repl.rich_output.output_catalog import OutputVideoAvi
>>> OutputVideoAvi.example()
OutputVideoAvi container
ext = '.avi'#
mimetype = 'video/x-msvideo'#
class sage.repl.rich_output.output_video.OutputVideoBase(video, loop=True)[source]#

Bases: OutputBase

Abstract base class for rich video output

INPUT:

  • video – OutputBuffer. The video data.

  • loop – boolean. Whether to repeat the video in an endless loop.

EXAMPLES:

sage: from sage.repl.rich_output.output_catalog import OutputVideoOgg
sage: OutputVideoOgg.example()  # indirect doctest
OutputVideoOgg container

>>> from sage.all import *
>>> from sage.repl.rich_output.output_catalog import OutputVideoOgg
>>> OutputVideoOgg.example()  # indirect doctest
OutputVideoOgg container
classmethod example()[source]#

Construct a sample video output container

This static method is meant for doctests, so they can easily construct an example. The method is implemented in the abstract OutputVideoBase class, but should get invoked on a concrete subclass for which an actual example can exist.

OUTPUT:

An instance of the class on which this method is called.

EXAMPLES:

sage: from sage.repl.rich_output.output_catalog import OutputVideoOgg
sage: OutputVideoOgg.example()
OutputVideoOgg container
sage: OutputVideoOgg.example().video
buffer containing 5612 bytes
sage: OutputVideoOgg.example().ext
'.ogv'
sage: OutputVideoOgg.example().mimetype
'video/ogg'

>>> from sage.all import *
>>> from sage.repl.rich_output.output_catalog import OutputVideoOgg
>>> OutputVideoOgg.example()
OutputVideoOgg container
>>> OutputVideoOgg.example().video
buffer containing 5612 bytes
>>> OutputVideoOgg.example().ext
'.ogv'
>>> OutputVideoOgg.example().mimetype
'video/ogg'
html_fragment(url, link_attrs='')[source]#

Construct a HTML fragment for embedding this video

INPUT:

  • url – string. The URL where the data of this video can be found.

  • link_attrs – string. Can be used to style the fallback link which is presented to the user if the video is not supported.

EXAMPLES:

sage: from sage.repl.rich_output.output_catalog import OutputVideoOgg
sage: print(OutputVideoOgg.example().html_fragment
....:       ('foo', 'class="bar"').replace('><','>\n<'))
<video autoplay="autoplay" controls="controls" loop="loop">
<source src="foo" type="video/ogg" />
<p>
<a target="_new" href="foo" class="bar">Download video/ogg video</a>
</p>
</video>

>>> from sage.all import *
>>> from sage.repl.rich_output.output_catalog import OutputVideoOgg
>>> print(OutputVideoOgg.example().html_fragment
...       ('foo', 'class="bar"').replace('><','>\n<'))
<video autoplay="autoplay" controls="controls" loop="loop">
<source src="foo" type="video/ogg" />
<p>
<a target="_new" href="foo" class="bar">Download video/ogg video</a>
</p>
</video>
