      The FFmpeg backend, before in loadMedia, check for the intent and sets flags accordingly

          if (playbackOptions.playbackIntent() == QPlaybackOptions::LowLatencyStreaming) {
        av_dict_set(dict, "fflags", "nobuffer", 0);
        av_dict_set_int(dict, "flush_packets", 1, 0);
        qCDebug(qLcMediaDataHolder) << "Enabled low latency streaming";
    }

      In a low latency network playback scenario (RTP) we would like to set network-caching to zero too.
