HLS_Cleanup on; cannot view

[kenanchristian]

Hi Guys, I'm very new to this media server thing. I've successfully built a RTMP-HLS media server using this module, and I've also manage to generate thumbnail periodically using a npm module.

But the thing is, when the hls fragment is deleted, the thumbnail also deleted. Then I found the hls_cleanup config on docs, but after I use it, I can't view the video.

This is my nginx.conf

daemon  off;
env PATH;

events {
    worker_connections 1024;
}

rtmp {
    server {
        listen 1935;
        chunk_size 4000;

        application encoder {
            live on;

nice post. personally I d use profile:v high for 720p and main for 480p

[campones]

about the cleanup, if you switch it off, I guess you ll have soon millions of fragment, except if you script something to remove the fragments once the live is over

[campones]

also you should know ffmpeg has resolution presets, you can use directly : -s hd720 or -s hd480

@campones How you deleted hls fragment manually. Can you share script of delete old fragment after some time.
