如何将兼容 HDMI 1.4a 的立体信号从 OpenGL 应用程序输出到 3DTV? [英] How can I output a HDMI 1.4a-compatible stereoscopic signal from an OpenGL application to a 3DTV?

问题描述

我有一个 OpenGL 应用程序，它通过 HDMI 将立体 3D 视频输出到现成的电视，但它目前要求显示器支持 1.4a 之前的手动选择正确格式的方法(并排、上下等).但是，现在我有一个我需要支持的设备，它只支持 HDMI 1.4a 3D 信号，据我所知，这是一种发送到显示器的数据包，告诉它 3D 视频的格式.我正在使用一个 NVIDIA Quadro 4000，我想知道是否有可能以标准 3DTV 将看到正确格式的方式输出我的视频(或告诉视频卡如何)，类似于 3D 蓝光或其他 1.4a- 兼容设备，无需手动选择某种 3D 模式.这可能吗?

I have an OpenGL application that outputs stereoscopic 3D video to off-the-shelf TVs via HDMI, but it currently requires the display to support the pre-1.4a methods of manually choosing the right format (side-by-side, top-bottom etc). However, now I have a device that I need to support that ONLY supports HDMI 1.4a 3D signals, which as I understand it is some kind of packet sent to the display that tells it what format the 3D video is in. I'm using an NVIDIA Quadro 4000 and I would like to know if it's possible to output my video (or tell the video card how to) in a way that a standard 3DTV will see the correct format, similar to a 3D Blu-ray or other 1.4a-compatible device, without having to manually select a certain 3D mode. Is this possible?

推荐答案

我没有看到问题的直接答案.

I don't see a direct answer for the question.

HDMI 1.4a 定义了描述 3D 格式的元数据.video_format 010 表示 3D3d_structure 0000 框架包装，0110 上下，1000 并排

HDMI 1.4a defines meta data to describe 3D format. video_format 010 means 3D 3d_structure 0000 frame packing, 0110 top-bottom, 1000 side-by-side

但是，如果驱动程序没有相应的 api，则您需要更改其代码(假设它已打开或您有权访问)

But, if the driver doesn't have an api for that, you need to change its code (assuming it's open or you have access)
