通过向浏览器发送视频来模拟网络摄像头 [英] Simulate a webcam by sending video to the browser

问题描述

我正在进行一项自动化测试，我向 Chrome 提供了一些参数，以尝试发送模拟网络摄像头捕获的视频.

I'm working on an automated test where I provide some parameters to Chrome in an attempt to send a video that simulates a webcam capture.

事实证明一切正常，但一段时间以来，视频开始仅显示为黑色背景，没有图像.

It turns out that everything was working, but for some time now, the video started to be displayed only as a black background, with no image.

我不知道这是不是巧合，但它发生在上次浏览器更新之后.

I don't know if it's a coincidence, but it happened after the last browser update.

有没有人给我提示?

使用的参数如下.

--use-fake-ui-for-media-stream--use-fake-device-for-media-stream--use-file-for-fake-video-capture

--use-fake-ui-for-media-stream --use-fake-device-for-media-stream --use-file-for-fake-video-capture

视频格式为 mjpeg@

the video format is mjpeg@

推荐答案

我遇到了类似的问题，这可能对您有所帮助.

I had similar problem, this might help you.

       ChromeOptions options = new ChromeOptions();
            options.AddArgument("--use-fake-ui-for-media-stream");
            options.AddArgument("--use-fake-device-for-media-stream");
            options.AddArgument("--use-file-for-fake-video-capture=filePath.y4m");
            options.AddUserProfilePreference("profile.default_content_setting_values.media_stream_camera", 1);

.y4m 格式的文件可能会解决您的问题，猜测值得一试.

File in .y4m format might resolve your problem, guess it's worth to take a shoot.
