树莓派HA接入萤石C6H的问题求助

flyinsea

先按照这个帖子 树莓派编译安装FFmpeg(添加H.264硬件编解码器支持) 安装ffmpeg ，安装的3.3.4版本，最新的4.0版本编译反而有问题，而且不支持ffserver了，所以用了3.0的最新版本3.3.4.

按照这位大大的帖子 [进阶教程] homebridge homeassistant 配置萤石C6H摄像头

接入萤石C6H。

配置参数如下
camera:
  - platform: ffmpeg
    input: -rtsp_transport tcp -i rtsp://admin:[email protected]:554/h264/ch1/main/av_stream
    name: ezviz
    extra_arguments: -pred 1 -q:v 2 -s 1280x720

ffmpeg:
    ffmpeg_bin: /usr/local/bin/ffmpeg


一开始按照上面帖子里编译参数，安装ffmpeg后发现没有enable image2和image2pipe导致出不来图像
后来加上 --enable-muxer=image2pipe 重新编译安装后，图像能出来了。但是还有个问题
预览图能出来，链接 url为 http://192.168.xxx.xxx:8123/api/ ... 37aa6fd4aabfab9e31c
大概是10s左右更新一次画面
点击该预览图进入实时画面，对应图片显示不出来，url链接 为 http://192.168.xxx.xxx:8123/api/ ... 37aa6fd4aabfab9e31c

就是说camera_proxy_stream 无法显示，camera_proxy 正常处理。如附图所示

log里也看不出什么来，摘取部分log如下，请问这个该从哪方面去解决？
