Playing H.265

H.265 (High Efficiency Video Compression — HEVC) is a new video compression format that gradually comes to replace H.264. It allows reduction of the file size compared to the previous H.264 standard up to 25-50%. At this, image quality remains high. It supports frame formats up to 8K (UHDTV) with a resolution of 8192×4320 pixels.

Instead of macroblocks that were used in H.264, blocks with a tree-like encoding structure are used in HEVC. The benefit of the HEVC encoder is that it uses larger blocks. The use of such blocks increases the efficiency of encoding while reducing the decoding time.

H.265 is a solution for screen resolutions higher than FullHD and is supported on various encoders: software, GPU (Nvidia NVENC, Intel Quick Sync), and hardware-based ones. Also, H.265 can be found on satellite TV and IP cameras.

On smartphones, H.265 is likely to be played on the processor, thus heavily loading the battery of the device.

H.265 is also supported by set-top boxes and SmartTV.

H.265 support in protocols

  • In the HLS protocol, the H.265 format has been maintained for a long time.
  • In the MPEG-TS protocol, the H.265 format is supported.
  • In the RTSP protocol, the H.265 format is supported. There is packaging in both SDP and RTP. The known issue with the transmission of bframes via RTSP is for a separate discussion.

H.265 support in players

The latest versions of VLC Media Player have built-in support for the H.265 format.
