You should not allocate the 256 decoders if the encoder is a
AV_CODEC_FLAG_RECON_FRAME one, as they will not be used.
Doing so would save memory and speed up initialization.

The proper check is (s->avctx->flags & AV_CODEC_FLAG_RECON_FRAME).
avci->recon_frame could start being allocated unconditionally in the

The docomentation says:
/**
* When the AV_CODEC_FLAG_RECON_FRAME flag is used. the encoder should store
* here the reconstructed frame corresponding to the last returned packet.
*
* Not allocated in other cases.
*/
AVFrame *recon_frame;
If thats not meant to be assumed to be true, the documentation should state
this differently
thx
