libcdio indev AVOptions:
  -speed             <int>        .D...... set drive reading speed (from 0 to INT_MAX) (default 0)
  -paranoia_mode     <flags>      .D...... set error recovery mode (default 0)
     disable                      .D...... apply no fixups
     verify                       .D...... verify data integrity in overlap area
     overlap                      .D...... perform overlapped reads
     neverskip                    .D...... do not skip failed reads
     full                         .D...... apply all recovery modes
