Part 1: What is HVC1 Codec?

HVC1 is a file extension that contains RAW data encoded with H.265/HEVC video compression file format. HVC1 is a codec ID for HEVC codec. Simply put, codec ID is a unique registered identifier that represents the encoding stored within the Track. H.265 videos use both HVC1 and HEV1 codec IDs. For example, newer Apple devices record videos using HVC1/H.265 codec, and HEVC decoder by Apple is limited to "hvc1" subcodec, while Handbrake tags h.265 files as 'hev1'.

  • HVC1 /HEVC/H.265 indicates parameter sets shall not be in ES.
  • HEV1 /HEVC/H.265 indicates parameter sets may be in ES.

According to Wiki, an elementary stream (ES) is usually the output of an audio encoder or video encoder. ES contains only one kind of data (e.g. audio, video, or closed caption). An elementary stream may also be called "elementary", "data", "audio", or "video" bitstreams or streams. The format of the elementary stream depends upon the codec or data carried in the stream.

To check the codec ID of HEVC files, use the MediaInfo: menu -> View -> Tree -> Video -> Codec ID "hev1" or "hvc1". VLC, as it supports different containers, codecs, and tags, is a useful video player that is able to open HVC1 videos.

Part 2: What to Do if VLC can't Play HVC1 Codec?

Though VLC is supposed to play HVC1 videos, you may still encounter HVC1 VLC errors sometimes.

Solution 1: Install HEVC codec for VLC

Download a third-party codec pack that may solve VLC not playing HEVC errors and help VLC play HVC1-encoded videos. The HEVC codec pack we recommend is vlc-libde265, which is an open source implementation of H.265 codec for VLC to decode HEVC/H.265 videos using libde265. Download the plugin for VLC via PAA, then open Terminal and run the commands below to install:

  • sudo apt-get install vlc-plugin-libde265

Solution 2: Change HVC1 codec ID to HEV1

If installing a codec pack won't fix the "VLC doesn't support hvc1" error, change the HEVC codec ID from HVC1 to HEV1 and try again. You can do this in two methods:

  1. Download Handbrake and convert HEV1 HEVC to MKV/MP4 in x265 codec. Handbrake will use HEV1 codec ID instead of HVC1. Then try the converted video with VLC.
  2. Use this to set the codec tag: ffmpeg -i input -c:v hevc_videotoolbox -tag:v hev1 output.mp4

Solution 3: Convert HVC1 HEVC to MP4 for VLC

When changing the HEV1 and HVC1 codec for VLC with ffmpeg is too hard for you, there is the simplest solution: convert the HEVC HVC1 videos to H.264 files. This will also fix VLC HVC1 errors caused by advanced HEVC specifics and old hardware. The HEVC HVC1 video converter we recommend is Winxvideo AI.
