Your URL appears to resolve to a workable stream, but the .m3u8 does not contain a direct link to a transport stream,
you'll need to pipe it through ffmpeg.

Try creating a local .m3u8 file containing:

#EXTM3U
 #EXTINF:0,Channel Name
 pipe:///usr/bin/ffmpeg -loglevel fatal -i https://ws.hls.nimo.tv/live/su1599512427609rec4c3a4d7d72c1946e09a8d6ca157304_high/playlist.m3u8 -map 0 -copy_unknown -c copy -metadata -f mpegts pipe:1

Replace "Channel Name" with an appropriate name.

In the URL section of your network, change the URL to
file:///path/to/file.m3u8

Replacing /path/to/file.m3u8 with the actual path to your file, and yes that is supposed to be 3 slashes after file:

If you still have trouble scanning, try increasing the scan timeout.

Hi Hiro.

I changed as you guide.

However scan result still is fail

Plz help me for one more time.

Best regards!

You have put the pipe: entry into the Network URL. Don't do that.

In my original reply I said:

In the URL section of your network, change the URL to
file:///path/to/file.m3u8

You need to create a file, as you appear to have done, and then reference it with a file: URL as above.

I can't tell you exactly how to write that, as I don't know the filename or its location.
