Virtual Method
GrlSourcemay_resolve
since: 0.2.0
Declaration [src]
gboolean
may_resolve (
GrlSource* source,
GrlMedia* media,
GrlKeyID key_id,
GList** missing_keys
)
Description [src]
Checks whether key_id may be resolved with source for media, so that the
caller can avoid calling grl_source_resolve() if it can be known in
advance it will fail.
If the resolution is known to be impossible because more keys are needed in
media, and missing_keys is not NULL, it is populated with the list of
GrlKeyID that would be needed.
This function is synchronous and should not block.
