gboolean gtk_media_stream_is_seekable ( GtkMediaStream* self )
Checks if a stream may be seekable.
This is meant to be a hint. Streams may not allow seeking even if
this function returns
TRUE. However, if this function returns
FALSE, streams are guaranteed to not be seekable and user interfaces
may hide controls that allow seeking.
It is allowed to call
gtk_media_stream_seek() on a non-seekable
stream, though it will not do anything.
