The codec_id does not change. The
av_get_bits_per_sample(avctx->codec_id) does change though, from the
init to the decode.

Here is a sample run with debugging printing
(bps is av_get_bits_per_sample(avctx->codec_id)):
init: id 65541, bps 8
frame: sample_size 0, bps 0
frame: id 65541, bps 8
frame: PCM_DVD 65555, bpcs 0
frame: sample_size 0, n 0
