[英]Adding subtitles with fluent-ffmpeg
I'm trying to burn in subtitles into a video.我正在尝试将字幕刻录到视频中。 This command works perfectly from command line: ffmpeg -i in.mp4 -vf subtitles=sub.srt:force_style='Fontsize=20' out.mp4
此命令从命令行完美运行: ffmpeg -i in.mp4 -vf subtitles=sub.srt:force_style='Fontsize=20' out.mp4
My code on server side doesn't seem to do much (it creates test.mp4 though)我在服务器端的代码似乎没有做太多(虽然它创建了 test.mp4)
ffmpeg('temp/subtitleVideos/qTWVbM5pkKms_pJbE8OAvH3N.mp4')
.outputOptions(
'-vf subtitles=temp/subtitleVideos/qTWVbM5pkKms_pJbE8OAvH3N.srt'
)
.on('error', function(err) {
console.log('Error: ' + err.message);
})
.save(path + 'test.mp4');
and I get the following error: Error: ffmpeg exited with code 1: Error opening filters!
我收到以下错误: Error: ffmpeg exited with code 1: Error opening filters!
Ok, I've found our problem.好的,我找到了我们的问题。 It was incorrect format of .srt
file. .srt
文件格式不正确。 To compare, this is our incorrect file (=timing is important):为了比较,这是我们不正确的文件(=时间很重要):

00:00:03,372 --> 00:00:05,674

3
00:00:05,795 --> 00:00:08,905

and this one is correct:这是正确的:
