Error message how do I find out?

Errors are printed to the dev-console, and the "Error" panel on the demo page. You can add error event listeners to your application using event listeners (hls.on(Hls.Events.ERROR, (name, data) => { alert(data.error.message) }))

I gave you the manifestos.

Please describe the differences between each one, including what the intended or expected behavior is vs the actual behavior or result when attempting to play each asset. Note that the third asset ("supplementa_8.1.m3u8") does not play in Safari 17.2.1 which could be an indicator that it is invalid. Consider downloading the HLS Tools from Apple and running mediastreamvalidator to check for errors.

You have an LG TV, you can check yourself.

Thanks, robwalch. Yes, I know Apple at him dv_5.m3u8 works, I have a website specially pulled out for apple way dv_5.m3u8

The test links for these would be: dv_8.1.m3u8 / dv_5.m3u8 / supplementa_8.1.m3u8 I'm so click the link LG TV dv_8.1.m3u8 and dv_5.m3u8 does not respond 0:00, one supplementa_8.1.m3u8 there are answers 02:28:52 but don't play the black screen.

dv_8.1.m3u8 and dv_5.m3u8 (A media error occurred: manifesInompatibleCodecsError). supplementa_8.1.m3u8 (A media error occurred: bufferAppendError | Buffer appending error | Buffer append error).

dv_8.1.m3u8 and dv_5.m3u8 (A media error occurred: manifesInompatibleCodecsError).

"manifestIncompatibleCodecsError" means that none of the CODECS attributes contain media supported by the runtime platform. See https://github.com/video-dev/hls.js/issues/6086#issuecomment-1883310262. This suggests that WebOS does not support "dvh1.05.06" nor "dvh1.08.06" wrapped in ISO-BMFF via MSE.

Try playing the media playlists (video/hvc1/media.m3u8). Do they play? What is the media codec parsed by HLS.js? In Chrome I get playback with a parsed video codec of "hvc1.2.20000000.H150.B0" . The error you are getting for dv_8.1.m3u8 is a result of an incorrect CODEC value.

Repeat this for all of your assets and correct the CODEC values.

supplementa_8.1.m3u8 (A media error occurred: bufferAppendError | Buffer appending error | Buffer append error).

CODECS reads "hvc1.2.4.H150.b0" but HLS.js parses "hvc1.2.20000000.H150.B0". The former should be supported, but creating a SourceBuffer for "video/mp4;codecs=hvc1.2.4.H150.b0" and appending the media results in append errors. Try correcting the CODECS value. If you are still experiencing issues, consider reporting an issue to LG making sure that the version of WebOS and the hardware you are testing supported this media via MSE.

1) MSE yes works "dvh1.05.06" and "dvh1.08.06" LG TV the signal Dolby Vision works play. MSE supplementa_8.1.m3u8 hvc1.2.4.H150.b0" LG TV the signal Dolby Vision works play. MSE subtitles no, i made a separate vtt track for direct, audio name title no, usually show Russia and English.
