On Windows platform, Chrome supports PQ, HDR10 (PQ with static metadata), and HLG. Automatic Tone-mapping will be enabled based on static metadata (if present). HDR10+ SEI dynamic metadata wil be ignored while decoding and playback will downgrade to HDR10.
On macOS platform, Chrome supports PQ, HDR10 (PQ with static metadata), HLG. In SDR / HDR / Hybrid mode, the macOS system will automatically perform EDR to ensure that HDR is displayed correctly. Chrome / Edge shared the same code thus has the same decoding ability, Safari also supports the above all HDR formats.
Note 1: Firefox >= 120 just added HEVC decoding support (Windows platform only, experimental, need to manually set media.wmf.hevc.enabled=1
to enable the feature). Based on my testing, Firefox supports HEVC Main profile while doesn't support Main10 profile (HDR contents usually encoded with Main10 profile) yet, if the bug got fixed, I will re-test and update the table later.
There are two type of support type here:
- Type 1: Supports RPU dynamic metadata and Profile 5 (IPTPQc2).
- Type 2: Supports profiles like Profile 8/9 that has cross-compatible HDR10/HLG/SDR support.
For the first type, currently only Chromecast and Windows platforms have very limited support. On Windows platform, Chrome supports encrypted Dolby Vision content, for versions of Chrome >= 110, when manually passing --enable-features=PlatformEncryptedDolbyVision
switch and launch Chrome and when the system has installed the Dolby Vision extension and HEVC video extension, Profile 4/5/8 will be supported, "Supported" will be returned when querying the API (Note: For external HDR displays, if HDR mode is turned on, Microsoft's MediaFoundation has a bug and will not return "Supported" results).
For the second type, Profile 8/9 with cross-compatibility such as HLG, HDR10, SDR, using API to query with dvh1
, dvhe
, dva1
, dvav
will return "not supported" (for example :MediaSource.isTypeSupported('video/mp4;codecs="dvh1.08.07"')
), while when querying with hvc1
, hev1
, avc1
, avc3
, "supported" will be returned. The specific version of Chrome has different implementation details:
Chrome >= 122. as long as the platform supports HEVC, then it is supported. Assuming that the API used by developers is MSE, the logic will be something like below:
if (isTypeSupported('video/mp4;codecs="dvh1.08.07"')) {
if (use_rpu) {
// Playback should success. Chrome internally considers the codec to be Dolby Vision
// and uses RPU dynamic metadata.
source.addSourceBuffer('video/mp4;codecs="dvh1.08.07"');
...
} else if (dvcc.dv_bl_signal_compatibility_id === 1 ||
dvcc.dv_bl_signal_compatibility_id === 2 ||
dvcc.dv_bl_signal_compatibility_id === 4) {
// Playback should success. Chrome internally considers the codec to be HEVC,
// ignores RPU dynamic metadata, decode and render in HLG/HDR10/SDR mode.
// Note: If it is profile 5, source buffer can only be created with `dvh1` or `dvhe`
// mimetype.
source.addSourceBuffer('video/mp4;codecs="hev1.2.4.L120.90"');
...
} else {
// Playback should fails, for incompatible dolby profiles, if you use HEVC construct
// source buffer, it will always fails.
}
} else if (isTypeSupported('video/mp4;codecs="hev1.2.4.L120.90"')) {
if (dvcc.dv_bl_signal_compatibility_id === 1 ||
dvcc.dv_bl_signal_compatibility_id === 2 ||
dvcc.dv_bl_signal_compatibility_id === 4) {
// Playback should success. Chrome internally considers the codec to be HEVC,
// ignores RPU dynamic metadata, decode and render in HLG/HDR10/SDR mode.
source.addSourceBuffer('video/mp4;codecs="hev1.2.4.L120.90"');
...
} else {
// Playback should fails, for example when Chrome does not support profile 5 but you use
// HEVC construct SourceBuffer.
}
} else {
// Playback should fails, HEVC is not supported.
}
Versions 110 ~ 121 of Chrome on Windows, Dolby Vision is not playable at all if its not encrypted, this is a bug of the browser. Chrome on other platforms, such as macOS, Android, etc, as long as constructing source buffer with hvc1
, hev1
, avc1
, avc3
and the sample entry is not dvh1
, dvhe
, dva1
, dvav
, then the playback should be success.
Versions 107 ~ 109 of Chrome, if constructing source buffer with hvc1
, hev1
, avc1
, avc3
and the sample entry is not dvh1
, dvhe
, dva1
, dvav
, then the playback should be success.
Chrome 107 does not support the ability to extract HEVC static metadata, and all HDR10 video playback are downgraded to PQ only mode. HLG videos uses the video processor API provided by the GPU vendor for processing tone-mapping has a poor performance on some laptops, and playing 4K video may cause frame droping.
Chrome 108 supports the ability to extract HEVC static metadata. For videos with static metadata written in the container, the playback is okey on 108, but some videos are not written static metadata to their containers, thus Chrome 108 can not extract the static metadata from these videos which causing the playback to be downgraded to PQ only mode, and the max content light level maybe cutted to a low value for these videos. In addition, the HLG Tone-mapping algorithm on Windows platform has been switched to Chrome's own algorithm, which solves the problem of bad performance on the laptop when using video processor for HLG Tone-mapping. However, Chrome has been using 8 bit for Tone-mapping, which resulting an insufficient contrast ratio of the Tone-mapping result.
Chrome 109 makes the HDR -> SDR process to a 16 bit + zero copy process, which improves the accuracy of PQ Tone-mapping on Windows platform, thus the problem of the insufficient contrast ratio for HLG has been also solved, and the video memory usage has been reduced by about 50%.
Chrome 110 solves the problem of incomplete static metadata extraction. It supports the extraction of static metadata from both the bitstream and the container, thus the max content light level issue has been solved, and at this point all HDR issues should have been resolved.
Chrome 119 fixed 10bit video playback issues for AMD GPU on Windows platform (black screen when playing HLG video in SDR mode, 4K freezes, high memory usage, color change when switching full-screen, crash when playing SDR video in HDR mode).
Chrome 122 improved Dolby Vision cross-compatible playback ability.
Chrome 123 ensures that on Windows platforms, PQ/HDR10 video can be rendered at absolute brightness when system HDR mode is enabled. It also solves the problem of abnormal Tone-mapping issue when the window is dragged between SDR monitor / HDR monitor when multiple monitors are connected.
Chrome 124 solves the issue that on Windows platform when the NVIDIA RTX Auto HDR feature is enabled, page scrolling will cause video brightness transition.
Chrome 125 solves all issues with Intel HDR10 MPO, the feature has been re-enabled.

Note 1:The above three API have already took --disable-gpu
, --disable-accelerated-video-decode
, gpu-workaround
, settings - system - Use hardware acceleration when available
, OS version
etc... into consideration, and if Chrome version >= 107.0.5304.0
(There is a bug in Chrome 108 and previous versions on Windows platform. If a specific GPU driver version causes D3D11VideoDecoder to be disabled for some reason, although the hardware decoding is no longer available, APIs such as isTypeSupported may still return "support", the bug has been fixed in Chrome 109) and OS is macOS or Windows, the result are guaranteed.
Note 2: There is a bug for the Android platform, Chrome < 112.0.5612.0
does not return the actual support status of different devices (although Android >= 5.0 supports HEVC main profile SW decoding by default, however whether main10 profile is supported or not completely depends on hardware), and always assume that all HEVC profiles and resolution are supported. Chrome >= 112.0.5612.0
now solves this bug, and will return the correct result depends on hardware and the given video's resolution. Just like Windows and macOS, the above three APIs are supported as well, and every influencing factors should have been taken into account.
Note 3:Compared with MediaSource.isTypeSupported()
or CanPlayType()
, we recommand using MediaCapabilities
, since MediaCapabilities
not only takes settings - system - Use hardware acceleration when available
etc... into consideration, but also check if the given width and height
is supported or not since different GPU may have different max resolution support, eg: some AMD GPU only support up to 4096 * 2048, and some old GPU only support up to 1080P.

Edge uses VDAVideoDecocder
to call MFT
(need to install HEVC Video Extension
, Edge 117 ~ 121 uses MediaFoundationRenderer
, and switch back to the original VDAVideoDecocder
after version 122) to finish the HEVC HW decoding which is the same tech behind Movies and TV
builtin system app.
Firefox (>= 120, experimental, need to manually set media.wmf.hevc.enabled=1
to enable the feature) uses DXVA MFT (need to install HEVC Video Extension
) to finish the HEVC HW decoding which is the same tech behind Movies and TV
builtin system app.
Chrome uses D3D11VideoDecoder
to call D3D11VA
(no need to install anything) to finish the HEVC HW decoding which is the same tech behind video players like VLC
.
Edge and Chrome use the same decoding implementations on macOS.
Safari and Chrome use the same VideoToolbox
to finish the HEVC HW decoding.
- Open
chrome://gpu
, and searchVideo Acceleration Information
, you should see Decode hevc main field and Decode hevc main 10 field (macOS will show Decode hevc main still-picture and Decode hevc range extensions as well, Windows Intel Gen10+ iGPU will show Decode hevc range extensions as well) present if hardware decoding is supported (macOS is an exception here, you see this field doesn't means the decode will use hardware, it actually depends on your GPU). - Open
chrome://media-internals
and play some HEVC video (Test Page) if the decoder isVDAVideoDecoder
orD3D11VideoDecoder
orVaapiVideoDecoder
that means the video is using hardware decoding (macOS is an exception here, if the OS >= Big Sur, and the GPU doesn't support HEVC, VideoToolbox will fallback to software decode which has a better performance compared with FFMPEG, the decoder isVDAVideoDecoder
in this case indeed), and if the decoder isFFMpegVideoDecoder
that means the video is using software decoding. - Open
Activity Monitor
on Mac and searchVTDecoderXPCService
, if the cpu usage larger than 0 when playing video, that means hardware (or software) decoding is being used. - Open
Windows Task Manager
on Windows and switch toPerformance
-GPU
, ifVideo Decode
(Intel, Nvidia) orVideo Codec
(AMD) usage larger than 0 when playing video, that means hardware decoding is being used.
Please make sure you are using Windows 8 and above, this is because the D3D11VideoDecoder
doesn't support Windows 7.
Please make sure you are using macOS Big Sur and above, this is because CMVideoFormatDescriptionCreateFromHEVCParameterSets
API has compatibility issue on lower macOS.
Some GPU driver may has bug which will cause D3D11VideoDecoder
forbidden to use. in this case, you need to upgrade your GPU driver and try again. See reference
Some GPU hardware may has bug which will cause D3D11VideoDecoder
forbidden to use. in this case, we can't do anything else but to use the FFMPEG software decode. See reference
- Follow the official build doc to prepare the build environment then fetch the source code from
main
branch (HEVC HW codes has been merged). - (Optional) To enable HEVC software decoding: switch to
src/third_party/ffmpeg
dir, then executegit am /path/to/add-hevc-ffmpeg-decoder-parser.patch
. If failed to apply the patch, could also trynode /path/to/add-hevc-ffmpeg-decoder-parser.js
to enable software decoding (Node.js is required to run the script), then switch tosrc
dir, and executegit am /path/to/enable-hevc-ffmpeg-decoding.patch
. - (Optional) To enable HEVC encoding support by default on Windows / macOS / Android, switch to
src
dir, then executegit am /path/to/enable-hevc-encoding-by-default.patch
. - (Optional) To integrate Widevine CDM to support EME API (like Netflix): switch to
src
dir, then executecp -R /path/to/widevine/* third_party/widevine/cdm
(Windows:xcopy /path/to/widevine third_party\widevine\cdm /E/H
). - If you are using
Mac
+ want to buildx64
arch (target_cpu tox86
,arm64
,arm
also available) + want to add CDM support, then rungn gen out/Release64 --args="is_component_build = false is_official_build = true is_debug = false ffmpeg_branding = \"Chrome\" target_cpu = \"x64\" proprietary_codecs = true media_use_ffmpeg = true enable_widevine = true bundle_widevine_cdm = true"
, if you are usingWindows
, you need to addenable_media_foundation_widevine_cdm = true
as well. - Run
autoninja -C out/Release64 chrome
to start the build. - Open Chromium directly.
If Electron >= v22.0.0, the HEVC HW decoding feature for macOS, Windows, and Linux (VAAPI only) should have already been integrated. To add HEVC SW decoding, the method should be the same with Chromium guide above.
