-----Update 24.06----- The RTX Video SDK, which has just been initially released, seems to consolidate all AI-related video enhancement technologies > Super resolution > Artifact reduction > SDR to HDR...
It seems that NVIDIA's official SDK explicitly supports hevc hardware encoding with an alpha channel in the [following note](https://docs.nvidia.com/video-technologies/video-codec-sdk/12.1/nvenc-video-encoder-api-prog-guide/index.html#hevc-alpha-encoding). Although the applications for this technique are very limited. Could you...
过去HEVC with Alpha的生产和消费都限定在Apple的设备上 最近,在另外一位开源作者rigaya的努力下,一个基于NV硬件的命令行工具[NVEncC](https://github.com/rigaya/NVEnc)也具备了HEVC with Alpha的编码能力 我们初步测试了一下,这个编码器的输出在macOS的Chrome下和苹果编码器输出的[结果一致](https://github.com/rigaya/NVEnc/issues/571#issuecomment-2283444981) 在最近的[x265 commit](https://bitbucket.org/multicoreware/x265_git/commits/c8c9d22075b26aa279b4d634c61889ca3d49656e)中,也出现了Alpha通道相关的代码更新,后续ffmpeg更新合进来应该只是时间问题。 上游编码器在今年都开始逐渐支持在Windows平台下的HEVC with Alpha生产,但windows下仍然缺少HEVC with Alpha的消费能力,而最有价值的应用场景就是浏览器。 在提供以上信息的基础上,想询问一下Windows平台下HEVC with Alpha的解码实现是否还在计划中。
