Summary:	port ulead dv audio decoder → support dvaudio in non dv container

There is nothing to port, dvaudio code is in dv demuxer

comment:3 by ami_stuff, 12 years ago

this seems to be already implemented for mov container (libavformat/mov.c)

#if CONFIG_DV_DEMUXER
    case AV_CODEC_ID_DVAUDIO:
        c->dv_fctx = avformat_alloc_context();
        c->dv_demux = avpriv_dv_init_demux(c->dv_fctx);
        if (!c->dv_demux) {
            av_log(c->fc, AV_LOG_ERROR, "dv demux context init error\n");
            return AVERROR(ENOMEM);
        }
        sc->dv_audio_container = 1;
        st->codec->codec_id = AV_CODEC_ID_PCM_S16LE;
        break;
#endif

etc.
