Video Output Types¶
This module defines the rich output types for video formats.
-
class
sage.repl.rich_output.output_video.
OutputVideoAvi
(video, loop=True)¶ Bases:
sage.repl.rich_output.output_video.OutputVideoBase
AVI video
EXAMPLES:
sage: from sage.repl.rich_output.output_catalog import OutputVideoAvi sage: OutputVideoAvi.example() OutputVideoAvi container
-
class
sage.repl.rich_output.output_video.
OutputVideoBase
(video, loop=True)¶ Bases:
sage.repl.rich_output.output_basic.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
-
classmethod
example
()¶ 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'
-
html_fragment
(url, link_attrs='')¶ 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>
-
class
sage.repl.rich_output.output_video.
OutputVideoFlash
(video, loop=True)¶ Bases:
sage.repl.rich_output.output_video.OutputVideoBase
Flash video
EXAMPLES:
sage: from sage.repl.rich_output.output_catalog import OutputVideoFlash sage: OutputVideoFlash.example() OutputVideoFlash container
-
class
sage.repl.rich_output.output_video.
OutputVideoMatroska
(video, loop=True)¶ Bases:
sage.repl.rich_output.output_video.OutputVideoBase

-
class
sage.repl.rich_output.output_video.
OutputVideoOgg
(video, loop=True)¶ Bases:
sage.repl.rich_output.output_video.OutputVideoBase

OutputVideoQuicktime
(video, loop=True)¶ Bases:

-
class
sage.repl.rich_output.output_video.
OutputVideoWebM
(video, loop=True)¶ Bases:
sage.repl.rich_output.output_video.OutputVideoBase
WebM video
The video can be encoded using VP8, VP9 or an even more recent codec.
EXAMPLES:
