#5894: Wrong -auto-alt-ref option type
------------------------------------+--------------------------------------
Reporter: kagami | Type: defect
Status: new | Priority: normal
Component: avcodec | Version: git-master
Keywords: libvpx,vp9 | Blocked By:

------------------------------------+--------------------------------------
libvpx API allows 0, 1 and 2 values for `enable_auto_alt_ref` option in
case of VP9, see
[[https://chromium.googlesource.com/webm/libvpx/+/v1.6.0/vp9/vp9_cx_iface.c#257|vp9_cx_iface.c]].
But ffmpeg uses `AV_OPT_TYPE_BOOL` for it, thus making impossible to
enable `multi_arf_allowed` mode.
