@baxgas can you look at it? Have you ever used butt (see https://github.com/AzuraCast/azuracast.com/blob/master/StreamingSoftware.md)? Use dev server for tests.

@baxgas we could use the song name info (see picture) sent by butt to transfer the live show's subtitle (e.g., 'Noise 'n Roses' -> comes from DJ Streamer's Display Name set in Azuracast and 'Judit, Bertók etc.' -> comes from butt). The song name ("yo" in this example) is included in the JSON of the nowplaying interface.

Bummer, it's not fully done yet: when a live DJ starts and didn't convey the subtitle yet (from Butt), the subtitle from the last song is being shown. Any idea?

Expected: empty string is shown until not connected.

Workaround until fix: quickly enter subtitle via Butt.

Update: AzuraCast/AzuraCast#1968

Workaround: can't we script Butt somehow to send update upon new connection?

[gammaw]

No reaction from Azuracast (see issue) nor from Butt developer (emailed them). Decision: try to find the bug in Azuracast, fix it and create pull request

Update:

• key principle (Liquidsoap): internal AzuraCast REST API is called upon live DJ lifecycle change.
• key classes (AzuraCast repo): InternalController.php and NowPlaying.php.
• two new comments posted in Azuracast thread.

Interesting news! I managed to send a metadata update HTTP request directly to the Icecast server (while live broadcasting from Butt). I simply used a browser (logged in to the Icecast admin page). This has the same effect as Butt would do it (via the song name change button). Azuracast is informed automatically and the change is visible in the admin page and is also updated in the nowplaying API (I didn't manage to figure out how this propagation works).

Workaround candidate for the issue: send HTTP request upon successful connectin in Liquidsoap. Liquidsoap has commands for sending HTTP requests.

Update: we don't need to go over HTTP, we can add metadata directly in Liquidsoap.

Conlusion: it seems that there is no easy solution for this issue.

Background:

• Problem with Liquidsoap: every time Butt connects, Liquidsoap resends the title of the song from the previous session.
• Problem with Butt: every time Butt connects, it sends the last okayed sing title.

Fix idea (won't work): set default title (e.g., live) when a Butt client connects. This would be possible in the Liquidsoap config in the live_connected function (see here). Unfortunately, the metadata update by LS and Butt (see above) comes later and overwrites this.

Fix plan: see here.

@pvj @baxgas: maybe I don't see obvious solutions, do you have any idea how to solve this quick & dirty?

See if this helps: #209

Status:

• AC addressed the issue but it won't work for us, see: Metadata on DJ connect is incorrectly cached AzuraCast/AzuraCast#2728 (comment) .
• Butt also address it, and it's a partial fix, see: https://sourceforge.net/p/butt/feature-requests/27/#e1e6
• Based on the new inputs, tried to ping the LS folks again: Suppress Liquidsoap inserting metadata automatically  savonet/liquidsoap#1096 (comment)
