A command line tool that converts subtitle files from SubRib (.srt) format to WebVTT (.vtt) format

SRT to VTT Command Line

A command line tool that converts subtitle files from SubRib (.srt) format to WebVTT (.vtt) format.

If you'd rather use a GUI than the command line, check out the SRT to VTT Converter.

Binaries

• Windows
• Mac OS X
• Linux - build instructions

Usage

For the most basic usage, simply put the binary file in the same directory as the .srt files you want to convert and run the converter. This will convert all files in that directory and save them with the .vtt extension.

For more advanced usage, see below:

srt-vtt  [-q] [-v] [-r] [-o <string>] [-t <integer>] [--] [--version] [-h] <string>

  -q,  --quiet
    Prevents details about the conversion from being printed to the console.
    Overrides --verbose.

  -v,  --verbose
    Indicates that details about the conversion should be printed to the console.

  -r,  --recursive
    If the input is a directory, this flag indicates its subdirectories will be searched
    recursively for .srt files to convert. This flag is ignored if the input path is a
    file.

  -o <string>,  --output-dir <string>
    The path to a directory where all output VTT files will be saved.

  -t <integer>,  --offset <integer>
    Timing offset in milliseconds. Can be any integer between 2147483647 and -2147483648.

  --,  --ignore_rest
    Ignores the rest of the labeled arguments following this flag.

  --version
    Displays version information and exits.

  -h,  --help
    Displays usage information and exits.

  <string>
    Path to a file to convert or directory containing files to convert (to convert files
    in a directory and it's subdirectories, include the -r switch).

  If called without any arguments, all .srt files in the current directory will be
  converted and saved within the current directory.

srt-to-vtt-cl's Issues

Converting UTF-16 encoded files is not supported on your platform

I am on linux.
What is needed to use it on linux?
Is it some library that is needed to do this converting? And then code to implement?

codecvt not available in Debian/Jessie

I've downloaded the last branch, when I try to Make, g++ says:

g++ -std=c++11 -O2 -MMD -I ./deps -c -o src/Utils.o src/Utils.cpp
src/Utils.cpp:11:19: fatal error: codecvt: No such file or directory
#include

the GCC output is:

Different encoding is randomly detected for the same input file

The file encoding appears to be randomly determined when processing this file: http://durian.blender.org/wp-content/content/subtitles/sintel_en.srt

The file is UTF-8, so the output in the case UTF16 is detected is, of course, gibberish.

Log displayed below:

Updated Windows binary file

Hello again,
Would it be possible to generate a new Windows binary that includes the fix from commit 1344e20? I don't have a Windows machine, so I was unable to generate a new binary with I made the pull request. Thanks.

UTF-8 ó -> ó

The "ó" is changed to ó during the SRT - VTT convertion

Creates invalid VTT files

The timestamp format is supposed to use decimal points instead of commas. This program does not make that change.

Standard input and output

Hello
please add an option to read from standard input and an option to write to standard output.
Thanks.

Srt to vtt conversion stops where ' is detected

While converting Srt to vtt . if sub title has apostrophe in the text " ' " conversion stops at that point without any error

comma to dots not converted

Describe the incorrect output

The commas in the srt are not converted to dots in vtt.

System Info

Windows 7 64b , command line version of converter

Sample SRT File

pressure_1b.zip

File was created manually in NotePad2. Using ANSI encoding (default).

Trying to run it from c#

Hello, I tried to run the code from c# but the process did not end and the file was not converted. this is a portion of the code used. Do you have any idea?

  public static void test7()// It did not end, no error but no file and still waiting
        {
            System.Diagnostics.Process process = new System.Diagnostics.Process();
            System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
            startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
            startInfo.FileName = "cmd.exe";
            startInfo.Arguments = "srt-vtt a.srt ";
            startInfo.WorkingDirectory = @"C:\Users\Salma\Desktop\test\";
            startInfo.UseShellExecute = true;
            process.StartInfo = startInfo;
            process.Start();
            process.WaitForExit();
            process.Close();

            var t = process.HasExited;
        }

Able to convert VTT to SRT?

Thanks for this awesome tool @nwoltman -- I was wondering if this can go in reverse, and convert a VTT file to SRT? I didn't see anything in the documentation but wanted to confirm.

Thanks!
