Latest git commit fails to build - CodecDownMix vs. CodecDownmix

[seahawk1986]

This looks like an unintended inconsistency:

codec.c: In function 'CodecVideoDecode':
codec.c:516:21: warning: variable 'first_time' set but not used [-Wunused-but-set-variable]
  516 |     static uint64_t first_time = 0;
      |                     ^~~~~~~~~~
codec.c: In function 'CodecAudioUpdateFormat':
codec.c:1163:37: error: 'CodecDownMix' undeclared (first use in this function); did you mean 'CodecDownmix'?
 1163 |                                     CodecDownMix ? AV_CH_LAYOUT_STEREO : audio_ctx->channel_layout,
      |                                     ^~~~~~~~~~~~
      |                                     CodecDownmix
codec.c:1163:37: note: each undeclared identifier is reported only once for each function it appears in
