HAP encoding incompatiblity

[NNois]

Hi, the hap codec widely used in real-time video applications use a switch named "format" for selecting the codec type and cause an incompatibility with the "format" option used by ffmpeg-python

ffmpeg -h encoder=hap:
Hap encoder AVOptions:
  -format            <int>        E..V....... (from 11 to 15) (default hap)
     hap             11           E..V....... Hap 1 (DXT1 textures)
     hap_alpha       14           E..V....... Hap Alpha (DXT5 textures)
     hap_q           15           E..V....... Hap Q (DXT5-YCoCg textures)
  -chunks            <int>        E..V....... chunk count (from 1 to 64) (default 1)
  -compressor        <int>        E..V....... second-stage compressor (from 160 to 176) (default snappy)
     none            160          E..V....... None
     snappy          176          E..V....... Snappy

that's raising an error: [AVFormatContext @ 000002cabb250880] Requested output format 'hap_q' is not known.

how to make it work without modifing ffmpeg-python ?
