Unable to convert LF vtt content to smi
Hello there.
I have an issue trying to convert a vtt content to smi.
When I convert CRLF files it works just fine, but I'm getting subtitles from a service that returns me LF files, and when I try to convert them, i only get an empty body on my smi file, like:
<SAMI>
<HEAD>
<TITLE></TITLE>
<STYLE TYPE="text/css">
<!--
P { font-family: Arial; font-weight: normal; color: white; background-color: black; text-align: center; }
.LANG { Name: English; lang: en-US; SAMIType: CC; }
-->
</STYLE>
</HEAD>
<BODY>
</BODY>
</SAMI>
If I locally save manually the file as CRLF, the conversion works fine.
But using a regex , such as .replace(/(?<!\r)\n/g, '\r\n') to replace end of lines doesn't seem to work.
This is an example of a subtitle file I'm trying to convert:
vtt.zip
Any ideas on that?
Thanks.
Problem with blank lines in VTT file
In VTT files, a blank line indicates the end of the cue. So if you have something like "Line 1\r\n\r\nLine 2" you need to write a space to the otherwise blank middle line. Here's a fix to the build() function in vtt.js.
if (typeof caption.type === "undefined" || caption.type == "caption") {
content += (i + 1).toString() + eol;
content += helper.toTimeString(caption.start) + " --> " + helper.toTimeString(caption.end) + eol;
content += replaceAll(caption.text, "\r\n\r\n", "\r\n \r\n") + eol; //ADD A SPACE TO EACH BLANK LINE
content += eol;
continue;
}
For testing, I've attached the SSA cues from One Piece S13:E1030 on Crunchyroll. Lines 118 & 119 have cues with two blank lines between two text lines. In the VTT output these lines need to have spaces:
98
00:06:22.240 --> 00:06:22.860
Ascensore diretto per l'8° piano
(In discesa ferma a tutti i piani)
99
00:06:22.860 --> 00:06:23.610
Ascensore diretto per l'8° piano
(In discesa ferma a tutti i piani)
smi without <SAMI> fails
Many smi files just start with <SYNC...> without <SAMI...> or <BODY...>, etc. Example: https://reflat.net/blog/rocketman/view/?seq=90256
Have a way to specify subtitle format of the input file
I have converted few .srt files to .vtt. But sometime i get the error "Cannot determine subtitle format" while the input file is correctly formatted by .srt.
Is there anyway to make it works? (like help the parser know exactly what kind of input format)
Thanks for making this awesome library
Output is blank
const subsrt = require('subsrt');
const vttContent = `WEBVTT
00:00.000 --> 00:04.000
Welcome to English in a Minute.
00:04.000 --> 00:07.000
Most people enjoy going to parties.
00:07.000 --> 00:25.000
You got to be a...`;
const options = { format: 'srt' };
const srtContent = subsrt.convert(vttContent, options);
console.log('SRT content:', srtContent);
keep getting "Unknown part 1" in command line
Dear papnkukn,
Thank you for creating this wonderful cli.
When I use the "parse" command e.g.
subsrt parse sample.srt output.json --verbose
I keep getting the following message "WARN: Unknown part 1" and the first section in srt can never be written in the json output.
Can you please advise?
Thank you very much!
SAMI html entities
The video player's I've tested don't parse the text of sami files, so the output is raw html entities.
I'm not sure if this is needed. seems to me in HTML markup single and double quotes don't need to be escaped, only opening and closing tag. Is there any specification that states this is necessary?

Any action drops first subtitle entry
Any action whether conversion, resync or otherwise causes the resultant file to consistently drop the first subtitle entry

Command line not working
Hi, your script looks promising, but it didn't work for me when I tried to install it globally and run it:
$ subsrt
module.js:538
throw err;
^
Error: Cannot find module '../subsrt.js'
I may take a look myself in case I don't find an alternative.
