我在家里使用AMCREST安全摄像头。我的目标是使用rtsp：//我的环境是Raspberry pi，将连接到我的NVR的IP摄像机的一个实时馈送到Webportal。
我能够成功启动ffserver，但是当我尝试传递输入视频并将其流式传输到video.ffm时，转换失败。
我在命令中尝试了各种参数组合，但是下面的参数似乎非常接近，仅出现一个错误（av_interleaved_write_frame（）：对等连接重置）
$ffmpeg -thread_queue_size 800 -i "rtsp://home:Home1234@192.168.1.32:554/cam/realmonitor?channel=4&subtype=0" -f lavfi -i aevalsrc=0 http://127.0.0.1:8090/video.ffm

我的期望是ffmpeg将开始将数据写入位于/ tmp目录中的video.ffm，以便我可以通过输入以下链接从浏览器或vlc媒体播放器读取数据 http://localhost:8090/stream
****** 2小时后更新******
我对命令参数做了些微更改，我的输出也进行了更改。在/ tmp文件夹中生成的临时视频文件看起来没有被video.ffm占用（我的分析可能是错误的）
