Play video with subtitles in JavaFX 2

问题 I notice that JavaFX 1 has a SubtitleTrack class for extracting subtitles from video files, but I can't find equivalent functionality in JavaFX 2 (a similarly named class in javafx.scene.media doesn't appear to exist. Is this functionality implemented at all in which case where has it moved to? Or is it planned for a future release? 回答1: I don't think video subtitle support was implemented for JavaFX 2.2. I think the Public API changes to media Tracks feature implements the functionality you

用Python抓取小破站视频字幕

因为某大户要得到某个B站视频的 「 字幕 」，自己手动记录字幕实在过于繁琐，每几秒都会有字幕不断地更新，一个1小时的视频字幕的收集便是一个浩大的工程~ 因此我再次召唤我的好帮手 网络爬虫 ，来帮我采集字幕并且以 srt 文件的格式保存。这个 srt 的全称是SubRip Text，这是一种非常流行的文本字幕，包含一行时间，一行字幕，制作规范非常简单。 如上图所示，这个字幕是CC字幕，CC是Closed Caption的简称，所谓CC字幕，就是隐藏式字幕。 CC 是把文字加入NTSC电视信号的一种标准化编码方法。 电视机的内置解码器或独立解码器能显示文字。 Caption 和我们常见的一般字幕（subtitle）的用法是有区别的，它是在无音状态下通过进行一些解释性的语言来描述当前画面中所发生的事情的字幕，例如画面中出现了背景的声音的时候，Caption都会通过字幕进行提示。 这个CC字幕我们可以再视频中拖放至任意位置，十分便捷，经过观察发现，该字幕显式地放在一个json之中，而这个json又可以通过Network找到。 上图中的 subtitle_url 便给出了字幕json的链接，而访问该链接可以得到该视频的所有字幕信息。其中对我生成srt文件最为重要的数据便是 from、to以及content，这些单词对应的数据分别代表某一条字幕的出现时间，消失时间以及字幕的内容。

Is it possible to extract SubRip (SRT) subtitles from an MP4 video with ffmpeg?

由 拥有回忆 提交于 2020-01-02 01:07:53
问题 I have checked the FFMpeg documentation and many forums and figured out the correct command-line to extract subtitles from an .MP4 video should look like so: ffmpeg -i video.mp4 -vn -an -codec:s:0 srt out.srt However, I get the following error, which lends me to question whether this is feasible at all: Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height Using ffmpeg -codecs , I can confirm that ffmpeg should be able to

Subtitles for AVPlayer/MPMoviePlayerController

I searched in Apple Documentation and found that I can achieve this by using the closedCaptionDisplayEnabled property of AVPlayer . I am interested to know what should be the format of subtitles? Will the .srt format do? Also can I achieve the same using MPMoviePlayerController ? Any help is appreciated. 回答1: Update 10/30/2018: It's worth checking this answer by an Apple engineer (Thanks to

Android Native Video player with subtitles

由 人走茶凉 提交于 2019-12-20 14:41:48
问题 I'm currently developing a video player for android. I've created a simple textview that shows the current subtitle. The problem is: MediaPlayer getCurrentPosition() method only gives me time in seconds. And I need that value in milliseconds to correctly synchronize the subtitle with the movie. The getCurrentPosition is supposed to give me the time in milliseconds, but it gives the time in seconds*1000 (every number ends with "000"). Do you know a better way of doing this? How do I get the
