Stream

A high-level object representing a single stream. It might be backed, or not, by an actual flow of data in a pipeline (#GstPad).

A #GstStream does not care about data changes (such as decoding, encoding, parsing,...) as long as the underlying data flow corresponds to the same high-level flow (ex: a certain audio track).

A #GstStream contains all the information pertinent to a stream, such as stream-id, tags, caps, type, ...

Elements can subclass a #GstStream for internal usage (to contain information pertinent to streams of data).

class Stream : ObjectGst {

this(string streamId, gst.caps.Caps caps, gst.types.StreamType type, gst.types.StreamFlags flags);

gst.caps.Caps getCaps();

gst.types.StreamFlags getStreamFlags();

string getStreamId();

gst.types.StreamType getStreamType();

gst.tag_list.TagList getTags();

void setCaps(gst.caps.Caps caps);

void setStreamFlags(gst.types.StreamFlags flags);

void setStreamType(gst.types.StreamType streamType);

void setTags(gst.tag_list.TagList tags);

}

Constructors

this this(string streamId, gst.caps.Caps caps, gst.types.StreamType type, gst.types.StreamFlags flags): Create a new #GstStream for the given stream_id, caps, type and flags

Inherited Members

From ObjectGst

checkUniqueness bool checkUniqueness(gst.object.ObjectGst[] list, string name): Checks to see if there is any object named name in list. This function does not do any locking of any kind. You might want to protect the provided list with the lock of the owner of the list. This function will lock each #GstObject in the list to compare the name, so be careful when passing a list with a locked object.
defaultDeepNotify void defaultDeepNotify(gobject.object.ObjectG object, gst.object.ObjectGst orig, gobject.param_spec.ParamSpec pspec, string[] excludedProps): A default deep_notify signal callback for an object. The user data should contain a pointer to an array of strings that should be excluded from the notify. The default handler will print the new value of the property using g_print.
replace bool replace(gst.object.ObjectGst oldobj, gst.object.ObjectGst newobj): Atomically modifies a pointer to point to a new object. The reference count of oldobj is decreased and the reference count of newobj is increased.
addControlBinding bool addControlBinding(gst.control_binding.ControlBinding binding): Attach the #GstControlBinding to the object. If there already was a #GstControlBinding for this property it will be replaced.
defaultError void defaultError(glib.error.ErrorG error, string debug_): A default error function that uses glib.global.printerr to display the error message and the optional debug string..
getControlBinding gst.control_binding.ControlBinding getControlBinding(string propertyName): Gets the corresponding #GstControlBinding for the property. This should be unreferenced again after use.
getControlRate gst.types.ClockTime getControlRate(): Obtain the control-rate for this object. Audio processing #GstElement objects will use this rate to sub-divide their processing loop and call gst.object.ObjectGst.syncValues in between. The length of the processing segment should be up to control-rate nanoseconds.
getGValueArray bool getGValueArray(string propertyName, gst.types.ClockTime timestamp, gst.types.ClockTime interval, gobject.value.Value[] values): Gets a number of #GValues for the given controlled property starting at the requested time. The array values need to hold enough space for n_values of #GValue.
getName string getName(): Returns a copy of the name of object. Caller should glib.global.gfree the return value after usage. For a nameless object, this returns null, which you can safely glib.global.gfree as well.
getParent gst.object.ObjectGst getParent(): Returns the parent of object. This function increases the refcount of the parent object so you should gst.object.ObjectGst.unref it after usage.
getPathString string getPathString(): Generates a string describing the path of object in the object hierarchy. Only useful (or used) for debugging.
getValue gobject.value.Value getValue(string propertyName, gst.types.ClockTime timestamp): Gets the value for the given controlled property at the requested time.
hasActiveControlBindings bool hasActiveControlBindings(): Check if the object has active controlled properties.
hasAncestor bool hasAncestor(gst.object.ObjectGst ancestor): Check if object has an ancestor ancestor somewhere up in the hierarchy. One can e.g. check if a #GstElement is inside a #GstPipeline.
hasAsAncestor bool hasAsAncestor(gst.object.ObjectGst ancestor): Check if object has an ancestor ancestor somewhere up in the hierarchy. One can e.g. check if a #GstElement is inside a #GstPipeline.
hasAsParent bool hasAsParent(gst.object.ObjectGst parent): Check if parent is the parent of object. E.g. a #GstElement can check if it owns a given #GstPad.
removeControlBinding bool removeControlBinding(gst.control_binding.ControlBinding binding): Removes the corresponding #GstControlBinding. If it was the last ref of the binding, it will be disposed.
setControlBindingDisabled void setControlBindingDisabled(string propertyName, bool disabled): This function is used to disable the control bindings on a property for some time, i.e. gst.object.ObjectGst.syncValues will do nothing for the property.
setControlBindingsDisabled void setControlBindingsDisabled(bool disabled): This function is used to disable all controlled properties of the object for some time, i.e. gst.object.ObjectGst.syncValues will do nothing.
setControlRate void setControlRate(gst.types.ClockTime controlRate): Change the control-rate for this object. Audio processing #GstElement objects will use this rate to sub-divide their processing loop and call gst.object.ObjectGst.syncValues in between. The length of the processing segment should be up to control-rate nanoseconds.
setName bool setName(string name): Sets the name of object, or gives object a guaranteed unique name (if name is null). This function makes a copy of the provided name, so the caller retains ownership of the name it sent.
setParent bool setParent(gst.object.ObjectGst parent): Sets the parent of object to parent. The object's reference count will be incremented, and any floating reference will be removed (see gst.object.ObjectGst.refSink).
suggestNextSync gst.types.ClockTime suggestNextSync(): Returns a suggestion for timestamps where buffers should be split to get best controller results.
syncValues bool syncValues(gst.types.ClockTime timestamp): Sets the properties of the object, according to the #GstControlSources that (maybe) handle them and for the given timestamp.
unparent void unparent(): Clear the parent of object, removing the associated reference. This function decreases the refcount of object.
connectDeepNotify ulong connectDeepNotify(string detail, T callback, Flag!"After" after): Connect to DeepNotify signal.
