如何使用gstreamer将网络摄像头视频保存到文件? [英] How to use gstreamer to save webcam video to file?

问题描述

我一直在尝试让emgu将相同的网络摄像头视频保存到文件中

问题是opencv仅支持avi，而avi似乎不太适合像X264这样的格式.

The problem is opencv only ssupports avi, and avi does not seem to suit a format like X264 very well.

我可以在C语言中使用Gstreamer来帮我吗?

Could I use Gstreamer to do this for me in C?

如果我也可以选择文件格式和容器类型，那就太好了.如果可以使用schrodinger dirac这样的格式，那将是很好的.

It would be good if I could choose the file format and container type too. It would be good if I could use a format like schrodinger dirac.

我是GStreamer的新手，所以我不太确定自己是否在正确的轨道上.

I'm new to GStreamer so I'm not quite sure if I'm on the right track here.

我设法使用

gst-launch-0.10 ksvideosrc！自动视频接收器

gst-launch-0.10 ksvideosrc ! autovideosink

现在如何将其转码为H264或dirac等格式?

Now how to transcode this to a format like H264 or dirac ...?

gst-launch-0.10 ksvideosrc num-buffers = 10！ encodebin2！ ffmpegcolorspace！ x264enc！ matroskamux！文件库 location = video.mkv

gst-launch-0.10 ksvideosrc num-buffers=10 ! decodebin2 ! ffmpegcolorspace ! x264enc ! matroskamux ! filesink location=video.mkv

这似乎创建了一个文件，但是VLC播放器无法读取它.

This seems to create a file, but VLC player can't read it.

推荐答案

此

gst-launch-0.10

gst-launch-0.10

ksvideosrc !  
decodebin2 !      
ffmpegcolorspace !
schronc ! 
matroskamux ! 
filesink location=gopro2.mkv

似乎可以处理狄拉克编码

Seems to handle dirac encoding

还有这个

gst-launch-0.10 ksvideosrc num-buffers = 500！ encodebin2！ ffmpegcolorspace！ x264enc！ mp4mux！ filesink location = gopro2.mp4

gst-launch-0.10 ksvideosrc num-buffers=500 ! decodebin2 ! ffmpegcolorspace ! x264enc ! mp4mux ! filesink location=gopro2.mp4

处理x264
