I'm trying to use hls.js to embed a video from a live stream in a website. I can play the video for instance in VLC or ffplay. ffmpeg -i http://192.168.11.10 gives some information about the stream:

Input #0, mpegts, from 'http://192.168.11.10':
  Duration: N/A, start: 40921.528689, bitrate: N/A
  Program 1
  Stream #0:0[0x44]: Video: h264 (Baseline) ([27][0][0][0] / 0x001B), yuv420p(progressive), 1280x720, 90k tbr, 90k tbn, 180k tbc

When I try to load the video directly using hls, I can see that data is being downloaded continuously, but no video is shown. The video control shows a spinning circle, pressing the play button does nothing. The Hls.Events.MANIFEST_PARSED event is never triggered.

<video id="test_video" controls autoplay></video>

var hls = new Hls({debug: true});
hls.on(Hls.Events.MEDIA_ATTACHED, function () {
    console.log(`HLS attached to video element ${hls.media.id}`);

    hls.loadSource('http://192.168.11.10');
    hls.on(Hls.Events.MANIFEST_PARSED, function (event, data) {
        console.log('Manifest loaded, found ' + data.levels.length + ' quality level');
    });
});
hls.attachMedia(document.getElementById('test_video'));

I also tried this using an intermediate .m3u8 file. I'm not sure if I have the format correct, though:

#EXTM3U
#EXTINF:68400,MyVideo
#EXT-X-TARGETDURATION:68400
#EXT-X-STREAM-INF:BANDWIDTH=4000000,CODECS="avc1.42e02a",RESOLUTION=1280x720
http://192.168.11.10
#EXT-X-ENDLIST

and

hls.loadSource('test.m3u8');

Now Hls.Events.MANIFEST_PARSED is triggered, and I get some more information from hls in the browser's console. However, although there is still a continuous data stream coming in from the video server, there is no video either. No Hls.Events.ERROR event is triggered.

My question is: How can I fix this? Or maybe more in general, how can I get more information about what is going wrong?

(Note: I tried on Edge, Chrome and Firefox)
