 Summary of the bug:
 When compiling ffmpeg with libx265 support (--enable-libx265) I end-up
 getting only the encoder although decoder is missing:
 {{{
 $ /usr/local/ffmpeg/bin/ffmpeg -codecs 2>/dev/null | grep -Ei -e 'h26[45]'
 -e 'hevc'
  DEV.LS h264                 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10
 (decoders: h264 h264_v4l2m2m ) (encoders: libx264 libx264rgb h264_v4l2m2m
 h264_vaapi )
  DEV.L. hevc                 H.265 / HEVC (High Efficiency Video Coding)
 (encoders: libx265 hevc_vaapi )
 }}}
 While I would normally expect:
 {{{
 $ ffmpeg -codecs 2>/dev/null | grep -Ei -e 'h26[45]' -e 'hevc'
  DEV.LS h264                 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10
 (decoders: h264 h264_v4l2m2m ) (encoders: libx264 libx264rgb h264_omx
 h264_v4l2m2m h264_vaapi )
  DEV.L. hevc                 H.265 / HEVC (High Efficiency Video Coding)
 (decoders: hevc hevc_v4l2m2m ) (encoders: libx265 hevc_v4l2m2m hevc_vaapi
 )
 }}}
 From the configure output it does show:
 {{{
 Enabled decoders:
 ...
 adpcm_ea_xas            h264                    ra_288
 adpcm_g722              hap                     ralf
 adpcm_g726              hcom                    rasc
 adpcm_g726le            hevc                    rawvideo
 ...
 }}}

 configure options:
 {{{

 Hints of where to look into to trace this would be much appreciated.
 Thnx!
