每秒更改VLC流的帧数 [英] Change Frames Per Second for VLC Stream

问题描述

我们目前正在尝试使用VLC流式传输连接到我们Linux服务器之一(Ubuntu 12.04)的网络摄像头，尽管我们能够成功地流式传输视频并进行远程观看，但我们需要更改每秒的帧数(默认为24).我们目前正在使用以下命令来创建流:

We are currently experimenting with streaming a webcam attached to one of our Linux servers (Ubuntu 12.04) using VLC, and although we are able to successfully stream the video and view it remotely, we need to change the number of frames per second (which is defaulting to 24). We are currently using the following command to create the stream:

vlc v4l2:// :v4l2-dev=/dev/video0 \
            :v4l2-width=640 \
            :v4l2-height=480 -- \
            sout="#transcode{vcodec=theo,vb=256}:standard{access=http,mux=ogg,dst=:8090}" \
            -I dummy

有人可以向我们展示如何修改它以更改每秒的帧数吗?我们已经在线搜索并通过VLC文档进行了拖网，但找不到解决方案.

Would someone be able to show us how to modify this to change the number of frames per second? We have searched online and trawled through the VLC documentation and have been unable to find a solution.

更新

已向我们指出了fps参数，但可悲的是，这并不能解决问题-运行下面所示命令的输出(那里还有一些其他错误，但是尽管有这些错误，流仍可以正常运行，我们暂时只关注更改帧速率.

The fps parameter was pointed out to us but sadly this didn't fix the issue - output from running the command shown below (there are some other errors in there, but the stream is running fine despite those, we are just focused on changing the frame rate for now).

$ vlc -v v4l2:// :v4l2-dev=/dev/video0 :v4l2-width=640 :v4l2-height=480 --sout="#transcode{vcodec=theo,vb=256,fps=1}:standard{access=http,mux=ogg,dst=:8090}" -I dummy

推荐答案

在转码部分添加'fps ='应该设置帧率:#transcode {vcodec = theo，vb = 256，fps = 10}

Adding 'fps=' to the transcode part should set the framerate: #transcode{vcodec=theo,vb=256,fps=10}
