从网络摄像头获取视频流并使用rtp发送 [英] get video stream from webcam and sending it using rtp

问题描述

大家好，

我现在正在开发一个使用网络摄像头作为视频设备的会议应用程序.我可以按照以下文章中的DirectShow预览网络摄像头并使用它来捕获图像: DirectX.Capture类库 [ ^ ]

directshow lib将视频直接保存到磁盘上，我找不到直接从中获取视频流的方法.我尝试通过使用RTP以JPEG格式逐帧发送视频来发送视频.这些帧是我从网络摄像头捕获的图像.我知道我应该将其压缩为MJPEG或MPEG，但是找不到能够这样做的编解码器.不幸的是，我什至无法在接收器端成功观看视频.当我尝试将接收到的RTP数据包保存回JPEG格式进行查看时，出现错误消息无效参数".

那么，您能告诉我完成该步骤我必须做什么吗?我在Google搜索了几天，却找不到答案.请帮帮我.
在此先感谢您.

Hi everyone,

I am now developing an conferencing application which use webcam as a video device. I am able to preview the webcam and capture image from it using directshow following the article here: DirectX.Capture Class Library[^]

The directshow lib saves the video directly to my disk and I cannot find a way to get the video stream directly from it. I try to send the video by sending it frame by frame in JPEG format using RTP. These frames are images I captured from the webcam. I know that I should compress it as MJPEG or MPEG but I cannot find any codec capable of doing so. And unfortunately, I even cannot successfully viewing the video on the receiver side. There is error said "Invalid parameters" when I try to save received RTP packets back to JPEG format for viewing.

So could you tell me which step I have to do to get this done? I searched google for a days and cannot find an answer. Please help me out.
Thanks in advance.

尝试x624编解码器，对于这样的事情非常有用

try x624 codec, it''s very usefull for things like that

VLC streams quite nice on rtp
