Ubuntu系统安装 Gstrame

1、安装先决条件&＃xff0c;基础组件

https://docs.aws.amazon.com/zh_cn/kinesisvideostreams/latest/dg/producer-sdk-cpp.html

2、下载代码、安装插件

https://github.com/awslabs/amazon-kinesis-video-streams-producer-sdk-cpp

如果碰到更换清华源&＃xff0c;报这个错

Fix apt-get update “the following signatures couldn’t be verified because the public key is not available”

参考这篇文章解决&＃xff1a;

Fix apt-get update “the following signatures couldn’t be verified because the public key is not available” :: Chris Jean

3、验证

# 是否能执行&＃xff1f;
gst-launch-1.0

# 查看有哪些元素
gst-inspect-1.0

## 这个插件是否正确安装

gst-inspect-1.0 kvssink

四、将数据发送到视频流

https://docs.aws.amazon.com/zh_cn/kinesisvideostreams/latest/dg/gs-send-data.html

报错

WARNING: erroneous pipeline: no element "h264parse"

还是要安装成功这个包。

sudo apt-get install gstreamer1.0-plugins-bad

其中上面这个包&＃xff0c;很容易报错。只有更换为阿里云的软件源才能   apt-get install成功。

五、可以演示的视频

st-launch-1.0 videotestsrc name&＃61;a a.src ! b.sink autovideosink name&＃61;b

cd /home/bluewelkin/gst-docs/examples/tutorials
./basic-tutorial-1
