I cannot view HEVC (H.265), AVC (H.264), VC-1 videos, and HEIC photos on my Synology NAS. What can I do?

Symptom

You cannot view HEVC (H.265), AVC (H.264), VC-1 videos, or HEIC photos stored on your Synology NAS.

Resolution

Synology has transitioned the processing of media files using HEVC (H.265), AVC (H.264), and VC-1 codecs from the server to end devices. This change reduces unnecessary system resource usage and improves efficiency.

As a result, you may experience playback issues. Please refer to the following articles for workarounds or detailed information on various Synology packages.

Note:

  • Surveillance Station on DSM will continue to support server-side processing of AVC streams.
