The parser included by demux.c. That file calls avcodec_close() in 
certain situations, but the avctx is still used when calling 
av_parser_parse2() as it's expected that all the parameters are left 
intact, and all were until 327efa6633, where avctx->ch_layout started 
being uninitialized, and it shouldn't.
