A subclass should do as little as possible in its init method. In particular, it should not try to access resources. Failures during init are marshalled back to the manager through the worker's remote_create method, since there is no component state proxied to the manager yet at the time of init.
|
Subclasses have to implement this method.
|
Subclasses can override me. They should chain up first.
|
Method that must be implemented by subclasses to produce the gstparse string for the component's pipeline. Subclasses should not chain up; this method raises a NotImplemented error. Returns: a new pipeline string representation. |
Method that can be implemented by subclasses if they wish to interact with the pipeline after it has been created and set on the component. This could include attaching signals and bus handlers. |
Expand the given pipeline string representation by substituting blocks between '@' with a filled-in template.
|
Return a parse-launch string to join the fdsrc eater element and the depayer, for example '!' or '! queue !'. The string may have no format strings. |
