sorry for all the qa, i juse reinstall all my system.
install all the ffmpeg that need, the code is like this
camera:
- platform: ffmpeg
name: Front Camera
input: -rtsp_transport tcp -i rtsp://admin:[email protected]:554/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif
also i add this line.
ffmpeg:
ffmpeg_bin: /usr/bin/avconv
on the page i see it like this, but if i will press on it it will show image fine.
Can you unit test just Rtsp? Maybe try vlc media player?
if i will press on the camera the video will be pop up and how image.
Show the image where?
On Ha if i will press here.
Does this help?
I use wyze camera (modified firmware) with rtsp feed only
input: rtsp://tung:[email protected]/live
i use this
-rtsp_transport tcp -i rtsp://admin:[email protected]:554/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif
same issue 
ok i resolve the issue 
i add this line.
ffmpeg:
ffmpeg_bin: /usr/bin/ffmpeg
instead of
ffmpeg:
ffmpeg_bin: /usr/bin/avconv
Thank you so much for trying to help
Try with just the input statement in configuration.yanl
After changing the configuration.yaml I would
Recommend Check config and then restart
