Required methods
fn mode(&self) -> PipelineFlags[src]
fn mode(&self) -> PipelineFlags[src]Gets a sample from the pipeline of the currently displayed image in preview, in the specified format.
Note that if you use “ANY” caps for caps, then the current format of
the image is used. You can retrieve these caps from the returned sample
with gst_sample_get_caps().
caps
Some caps to specifying the desired format, or
GST_CAPS_ANY to use the native format
Returns
A sample of self’s current image preview in
the format given by caps, or None if an error prevented fetching the
sample.
Gets a sample from the pipeline of the currently displayed image in preview, in the 24-bit “RGB” format and of the desired width and height.
See thumbnail().
width
The requested pixel width of the image, or -1 to use the native size
height
The requested pixel height of the image, or -1 to use the native size
Returns
A sample of self’s current image preview in
the “RGB” format, scaled to width and height, or None if an error
prevented fetching the sample.
fn preview_get_audio_sink(&self) -> Option<Element>[src]
fn preview_get_audio_sink(&self) -> Option<Element>[src]Gets the property::Pipeline::audio-sink of the pipeline.
Returns
The audio sink used by self for preview.
fn preview_get_video_sink(&self) -> Option<Element>[src]
fn preview_get_video_sink(&self) -> Option<Element>[src]Gets the property::Pipeline::video-sink of the pipeline.
Returns
The video sink used by self for preview.
fn preview_set_audio_sink<P: IsA<Element>>(&self, sink: &P)[src]
fn preview_set_audio_sink<P: IsA<Element>>(&self, sink: &P)[src]Sets the property::Pipeline::audio-sink of the pipeline.
sink
A audio sink for self to use for preview
fn preview_set_video_sink<P: IsA<Element>>(&self, sink: &P)[src]
fn preview_set_video_sink<P: IsA<Element>>(&self, sink: &P)[src]Sets the property::Pipeline::video-sink of the pipeline.
sink
A video sink for self to use for preview
Saves the currently displayed image of the pipeline in preview to the given location, in the specified dimensions and format.
width
The requested pixel width of the image, or -1 to use the native size
height
The requested pixel height of the image, or -1 to use the native size
format
The desired mime type (for example, “image/jpeg”)
location
The path to save the thumbnail to
Returns
true if self’s current image preview was successfully saved
to location using the given format, height and width.
Sets the property::Pipeline::mode of the pipeline.
Note that the pipeline will be set to gst::State::Null during this call to
perform the necessary changes. You will need to set the state again yourself
after calling this.
NOTE: Rendering settings need to be set before setting
modetoPipelineFlags::RENDERorPipelineFlags::SMART_RENDER, the call to this method will fail otherwise.
mode
The mode to set for self
Returns
true if the mode of self was successfully set to mode.
fn set_render_settings<P: IsA<EncodingProfile>>(
&self,
output_uri: &str,
profile: &P
) -> Result<(), BoolError>[src]
fn set_render_settings<P: IsA<EncodingProfile>>(
&self,
output_uri: &str,
profile: &P
) -> Result<(), BoolError>[src]Specifies encoding setting to be used by the pipeline to render its
property::Pipeline::timeline, and where the result should be written to.
This method must be called before setting the pipeline mode to
PipelineFlags::RENDER.
output_uri
The URI to save the property::Pipeline::timeline rendering
result to
profile
The encoding to use for rendering the property::Pipeline::timeline
Returns
true if the settings were successfully set on self.
Takes the given timeline and sets it as the property::Pipeline::timeline for
the pipeline.
Note that you should only call this method once on a given pipeline
because a pipeline can not have its property::Pipeline::timeline changed after
it has been set.
timeline
The timeline to set for self
Returns
true if timeline was successfully given to self.
fn audio_filter(&self) -> Option<Element>[src]
fn audio_filter(&self) -> Option<Element>[src]The audio filter(s) to apply during playback in preview mode,
immediately before the property::Pipeline::audio-sink. This exposes the
playsink:audio-filter property of the internal playsink.
The audio filter(s) to apply during playback in preview mode,
immediately before the property::Pipeline::audio-sink. This exposes the
playsink:audio-filter property of the internal playsink.
fn audio_sink(&self) -> Option<Element>[src]
fn audio_sink(&self) -> Option<Element>[src]The audio sink used for preview. This exposes the
playsink:audio-sink property of the internal playsink.
The audio sink used for preview. This exposes the
playsink:audio-sink property of the internal playsink.
The timeline used by this pipeline, whose content it will play and
render, or None if the pipeline does not yet have a timeline.
Note that after you set the timeline for the first time, subsequent calls to change the timeline will fail.
fn video_filter(&self) -> Option<Element>[src]
fn video_filter(&self) -> Option<Element>[src]The video filter(s) to apply during playback in preview mode,
immediately before the property::Pipeline::video-sink. This exposes the
playsink:video-filter property of the internal playsink.

playsink:video-sink property of the internal playsink.
The video sink used for preview. This exposes the
