On Ubuntu 20.04,I build the docker image based my project located at
<https://github.com/hongyi-zhao/docker-nginx-rtmp>. I then tried
streaming the camera using HLS, as described below.

Publish the stream:

$ docker run -it -p 1935:1935 -p 8000:80 --rm nginx-rtmp
$ ffmpeg -f pulse -i default -f v4l2 -r 30 -s 1920x1080 -i /dev/video0
-c:v libx264 -preset veryfast -b:v 3000k -maxrate 3000k -bufsize 3000k
-vf "scale=1280:-1,format=yuv420p" -g 60 -c:a aac -b:a 128k -ar 44100
-force_key_frames "expr:gte(t,n_forced*4)"  -f flv

As for watching the stream, I tried ffplay and vlc, and the former can
successfully play the stream, but the latter failed. The used commands
are shown below:

$ ffplay http://localhost:8000/live/surveillance.m3u8
$ cvlc http://localhost:8000/live/surveillance.m3u8
VLC media player Vetinari (revision
[000056468a0b0e80] dummy interface: using the dummy interface module...

The vlc stuck there for ever.

Any hints for solving the problem?
