Ideas on using encode_metadata option in output.hls

[Russsgithub]

I have an icecast hls relay with input.http(icecast_source) as a source.

on_metadata shows title metadata.

I output with output.hls with encode_metadata set to true, but get no metadata in the resulting stream.

I see in the output hls ml file it inserts metadata if m exists so don't see why .

Any clues, am I doing something wrong.

Thank you.

I notice there is an open issue about this.

Unfortunately, this option does nothing with the %ffmpeg encoder. I'll be removing it for 2.0.1. There are several proposed standards for metadata with HLS but each time I look into it I am unable to find a reference implementation. If you can point me to the right info, I'd be happy to look at it again.

Hi Romain, I'll have a look into it and see what I can find. Thanks. On 18 Oct 2021 14:45, Romain Beauxis ***@***.***> wrote: Unfortunately, this option does nothing with the %ffmpeg encoder.

Hi Romain,

I've had a dig around, and found lots of confusing info.

The most useful to me seemed to be this script , hls-id3tags .

Which uses this script , hlsinjector.

Both projects have multiple stars on github which makes me think they work. I've not had a chance to test them, but thought you may gleen some information from them.

There is also -metadata title="foo" which seems to need -map-metadata , defaults to id3v2.4 (apparently windows doesn't like this) but can be set to 2.3 with -id3v2_version 3 .
I've seen this work (with ffprobe - it shows it the metadata field) but don't think it is the way to go.

Timed metadata seems to have to do with #EXT-X-DATERANGE and SCTE-35.

Here is a version of ffmpeg with scte-35 implementation, which may offer more info ... maybe.

I guess you may have seen these already , but if not I hope some of it helps.
