proposal : support webm

Post by parole » Sat Nov 09, 2024 7:33 am

I had to create an account just to report this bug. On Android, CUE support is not reliable.
I divide my downloaded .webm Youtube long audio files in CUE sheets.
Then I make playlists with specific audio from these CUE files in a personal order.
No problem with this method on my computer in foobar2000.

But the same CUE files are badly interpreted by NeutronMP on my Android telephone: the chapters are listed as such, but whatever track you want to play, NeutronMP only plays the first one from the CUE sheet.
Of course it’s as bad, not to say worse, if you make playlists with these chapters.

Of course one can say users can avoid this bug by re‐encoding the individual fragments as separate audio files. But that is a hassle and a waste of time (let’s say you want to divide a conference into topics, but later you have to divide the topics again, etc.).

So please provide full support of CUE sheets and also test the individual chapters when they are included in a playlist.

Additional information:
As described on https://en.wikipedia.org/wiki/Cue_sheet_(computing), the structure of the CUE file I made is:

Code: Select all

FILE "so and so.webm" MP3
  TRACK 01 AUDIO
    TITLE "introduction"
    INDEX 01 00:00:00
  TRACK 02 AUDIO
    TITLE "chapter 1"
    INDEX 01 01:15:00
…

Cue-sheets work fine in Neutron, here one of my countless examples :

Code: Select all

performer "Wynton Marsalis"
title "Untamed Elegance"
file "UNTAMED ELEGANCE -Full Concert- - Jazz at Lincoln Center Orchestra with Wynton Marsalis.m4a" m4a
  track 1 audio
    performer "Jazz at Lincoln Center Orchestra"
    title "Intro"
    index 01 00:00:00
  track 2 audio
    performer "Jazz at Lincoln Center Orchestra"
    title "The Business of America is Business"
    index 01 03:51:00
  track 3 audio
    performer "Jazz at Lincoln Center Orchestra"
    title "The Elephant in the Room"
    index 01 11:14:00
  track 4 audio
    performer "Jazz at Lincoln Center Orchestra"
    title "Laboratories of Ideas"
    index 01 20:58:00
  track 5 audio
    performer "Jazz at Lincoln Center Orchestra"
    title "The 'It' Thing"
    index 01 29:15:00
  track 6 audio
    performer "Jazz at Lincoln Center Orchestra"
    title "Drunk as a Skunk"
    index 01 36:06:00

    index 01 44:43:00

If you want us to check further, please provide an example music- and a corresponding cue file for testing.

Perhaps this issue is due to using the webm files. I'm not sure if these are containers for mp3 format will support cue files within Neutron.

As @blaubär has suggested, an example file and cue sheet might help confirm this.

I downloaded a webm test file from here, put some tags on it, and tried to play it. Couldn't be started directly from the explorer, it seems Neutron doesn't support webm. But recognized it when scanning, and then it played. But didn't show the length of the track :

And as webm isn't mentioned as supported by Neutron here I assume it isn't. That it plays at all is in this example perhaps due to its audio stream being opus, which is supported. And that would be a strong possible reason for cue sheets not working properly with webm - if Neutron cannot estimate the duration of the track then it might well have difficulties splitting it up into single tracks with defined duration.

Then let's propose to support the webm format.
