DMA Compatibility

You can enhance DMA compatibility to make sure the multimedia contents on your Synology NAS are played smoothly on your DMA devices.
Please note that file conversion will apply to every device once you have enabled this function. However, the results of conversion may be accepted by some DMAs only, depending on the media formats supported by your DMA.

To enable audio conversion:

  1. Tick Enable audio conversion and the following checkboxes to enable converters if your DMA does not support the following audio formats: FLAC, APE, AAC, OGG, and AIFF.
  2. Tick Downsample audio files during conversion to provide better DMA compatibility if you would like to reduce the data rate of audio files and provide better DMA compatibility.
  3. Click Apply.

To enable video conversion:

  1. Tick Enable video conversion and enter the video file extensions to be converted.
  2. Click Apply.

Note: This function is only available on certain models. For more information, please refer to Synology FAQ. Please also note that conversion occupies extra system resources and may lead to choppy playback. In order to prevent this from happening, please check if file formats of your videos are supported by your DMA, and fill in those formats which are not supported only.

To help DMA identify multimedia file formats:

  1. Tick Enable customized MIME types and enter the customized MIME types.
  2. Click Apply.

About MIME Types

MIME types, also known as Internet media types, can improve the compatibility of multimedia files with DMA by specifying the type and sub-type of media files. You can customize the MIME types to help your DMA device identify the correct file formats.

To manage the list of DMA devices:

  1. Tick Restrict access to Media Server for newly detected UPnP/DLNA devices if you do not wish to leave Media Server open to new devices.
