Crossfading stops after request put on queue switched-to by fallback

[Warblefly]

Following-up my earlier note (#1735), crossfading in a playlist using liq_cross_duration and liq_cue_in to mark fade points and the end of start-of-track silencing works at first, but stops after a request is placed on a request queue selected by fallback.

This request queue has items pushed onto it via telnet.

And, after the first such request, all subsequent crossfades don't work. The tracks simply play right through to the end of data.

The crossfade at the end of a track (marked by liq_cross_duration) is not heeded when the fallback function is used as below. The track fully finishes, to the end of its data.

myplaylist is the playing playlist; override is the queue onto which items are pushed by the expect/telnet combination.

myplaylist = fallback(track_sensitive=true, transition_length=30.0, [request.queue(id="override"), myplaylist])

But the multiple errors that used to happen are gone.

Here's the log:

Just checking again without inserting anything on the request queue, and it seems crossfading isn't working at all.

Version 1.4.4 overlaps perfectly, as expected.

Here's the log, from start-up: tracks 1 and 2 did not crossfade.

The log, strangely, says crossfading is happening; but it's not appearing on the output.

Thank you for looking into this, and I hope this log is helpful. First, here is the script:

[toots]

Thanks for this report, looking at it right now.

[toots]

I think I've got a handle of this issue. There are a couple of dynamic things at play.

The source is the issue seems to be that the playlist does not seem to have a new track ready when then old track ends. This is probably due to a change in playlist loading dynamic that I need to investigate. We've had a goal of simplifying how playlists queue requests for a while, perhaps it is time to change it. This is why you see: Analysis: -82.799226dB / -nandB (2.80s / 0.00s) and, so, the new track is not considered in the transition.

I'm going to investigate the issue on the playlists. For documentation sake, here's a script to reproduce the issue:

s = single("/path/to/file.mp3")

s = chop(every=20., s)

s = delay(2., s)

s = crossfade(s)

[Warblefly]

'Chop' and 'delay' — gosh, that's useful for checking any custom transitions I may end up writing when more confident (reading the Liquidsoap 2.0 book just now).

[toots]

@Warblefly would you be able to test with the use-requests-for-length branch? This should fix your issue.

[Warblefly]

Thank you for checking this. Going to do so now.

[Warblefly]

Sounds great to me! Thanks. Noted that playlist parameter "length" seems now to be an integer governing something to do with how many items in advance are processed? Not sure but have dropped it for now.

Having to do something else while listening and watching log but it's working, and so is the request.queue, and crossfades are sounding fine.

Can report more fine-grained stuff later. But I'm grateful to you for looking into this, and for being able to watch, now, how version 2 is progressing.

More later. JW

[toots]

Great, thanks for testing. Yes, with this PR I am changing the semantics on how request-based sources are filling up their queue by simply saying "I want length requests queued in advance". That's why length is now an integer. I believe that this how it should have always been.

[Warblefly]

Here's a log to after the first cross-fade, followed by the script, just in case they're useful to you.

Thanks! I gather that the issue is fixed with this PR @Warblefly ?

[Warblefly]

Thank you for checking. On the branch you've given me, and with the script above, some eight hours after starting the stream, with two request.queue additions each hour, it is still crossfading well, as far as my occasional checks, including now, can tell.

At first sight, therefore, yes, you've fixed it! JW

[Warblefly]

Still working flawlessly, 24 hours later.
