             Use const_iterator for QMap m_encoderList

 Use const_iterator, constBegin, constEnd and constFind while accessing
 the tvList and pointers to the tvList such as m_encoderList and m_tvList.
 This fixes the problem of crashing while deleting a recording.
 When deleting, the m_encoderList is accessed by more than one thread.
 The QMap is documented to be re-entrant but this appears to be only the
 case
 when the QMap is accessed with the const variants of the member functions.

 Fixes #13571
