static int query_formats(AVFilterContext *ctx)
    static const enum AVSampleFormat sample_fmts[] = {

    ff_set_common_channel_layouts(ctx, ff_all_channel_layouts());
    ff_set_common_formats(ctx, ff_make_format_list(sample_fmts));
    ff_set_common_samplerates(ctx, ff_all_samplerates());

    return ctx->ff_errno;
