QUESTION
I want to use "fvad" library to detect audio silence part, but I have QByteArray instead of SNDFILE. How can I do that?
...ANSWER
Answered 2019-Dec-08 at 10:30You should use sf_open_virtual instead of sf_open
to create the SNDFILE
instance.
So, as per the documentation, you should pass SF_VIRTUAL_IO*
to sf_open_virtual.
The definition for each member of that struct, have to be implemented to reflect your QBuffer. So, you need to create a helper class that accepts a reference to a QBuffer and implements methods with the same footprint as follows.
QUESTION
I am learning EF and I am trying to understand when to use which type of query.
For example this query:
...ANSWER
Answered 2018-Feb-05 at 21:43What are the main differences of querying one way to querying the other way?
Joins are harder to read and more error prone. EG does the second query return the same data as the first?
Is there any rule to follow for when using one or the other?
Use navigation properties whenever you can.
How can I mess performance in such cases or for SQL queries in general?
Incorrect joins can cause poor performance, and complex LINQ queries can cause unexpectedly-complex SQL. Also Eager Loading too many related entities can cause expensive queries.
