+@item q (@emph{-V})
+Set constant quality setting for VBR. This option is valid only
+using the @command{ffmpeg} command-line tool. For library interface
+users, use @option{global_quality}.
+
+@item compression_level (@emph{-q})
+Set algorithm quality. Valid arguments are integers in the 0-9 range,
+with 0 meaning highest quality but slowest, and 9 meaning fastest
+while producing the worst quality.

+@item reservoir
+Enable use of bit reservoir when set to 1. Default value is 1. LAME
