Serialise the service network to XML.
See docs/mlt-xml.txt for more information.
notes: >
If you set a data property beginning with (and longer than) "xml_retain" on
the service connected to this consumer where the data is a mlt_service
pointer, then the pointed at service will also be serialized before the
connected service. This can be useful, for example, to save a playlist as
a media bin along with a multitrack. You can serialize more than one of these
additional services by setting more than property, each with a unique key
beginning with "xml_retain".
bugs:
- Untested arbitrary nesting of multitracks and playlists.
- >
Property "id" is generated as service type followed by number if no
property named "id" exists, but it fails to guarantee uniqueness.
parameters:
- identifier: resource
argument: yes
title: File
type: string
description: >
The name of a file in which to store the XML.
If the value does not contain a period (to start an extension), then
the value is interpreted as the name of a propery in which to store the
XML. This makes it easy for an application to use the consumer to
serialize a service network and retrieve the XML in-memory.
readonly: no

mutable: no
default: stdout
widget: fileopen
- identifier: all
title: Process all frames
type: integer
description: >
Without this option, the XML consumer does not process any frames
and simply serializes the service network. However, some filters (.e.g,
videostab) require two passes where the first pass performs some
analysis and stores the result in a property. Therefore, set this
property to 1 (true) to cause the consumer to process all frames
before serializing to XML.

If a file name in the XML is relative, but not relative to the current
XML file's directory, then you can set the directory to which it is
