       -iopt param1=val1[&param2=val2...]

         dh=[1|0] (default: 0)

         Dump gavf headers

         Use this for debugging

         dp=[1|0] (default: 0)

         Dump gavf packets

         Use this for debugging

         dm=[1|0] (default: 0)

         Dump inline metadata

         No messages

         Don't attempt to make a back-channel for messages. Forward messages might still be sent.

       -aq param1=val1[&param2=val2...]

         Audio conversion options
         q=<number> (1..5, default: 2)

         Conversion Quality

         Set  the  conversion  quality  for  format  conversions. Lower quality means more speed. Values above 3
         enable slow high quality calculations.

         Default: auto

         Resample mode

         Resample mode. Auto means to use the quality  level.  Subsequent  options  are  ordered  by  increasing
         quality (i.e. decreasing speed).

         dm=<string>

         Supported strings: auto none rect tri shaped

         Default: auto

         Dither mode

         Dither  mode. Auto means to use the quality level. Subsequent options are ordered by increasing quality
         (i.e. decreasing speed).

       -vq param1=val1[&param2=val2...]

         Video conversion options
         q=<number> (1..5, default: 2)

         Conversion Quality
