Car*_*zón 19 dvd ffmpeg mkv avconv
这是我知道将DVD图像转换为另一个视频格式(vg MP4)的过程:
VTS_01_n个.VOB文件VIDEO_TS(对于n > = 0)连接到单个VOB文件中.avconv或ffmpeg将该VOB转换为另一种格式.到目前为止一直很好,但现在我想用字幕转换DVD图像.据我所知MKV格式支持字幕,所以它似乎是一个明显的选择.或者,我可以使用任何其他具有硬字幕的格式(字幕作为视频图像的一部分).
但是,DVD图像中的字幕编码是dvdsub,我得到以下错误
Only SUBTITLE_ASS type supported.
Subtitle encoding failed
但是,当avconv -codecs我跑步时,我得到:
...
DES dvdsub DVD subtitles
...
而-c:s copy开关,虽然它可以防止命令失败,但它似乎没有产生玩家可以理解的副标题.
那么,如何使用创建ass字幕？dvdsubavconv
我的VOB文件有八个字幕通道和两个音频通道.Ubuntu视频应用程序不显示任何字幕,只有第一个音频通道似乎正在工作,DVD图像可能会被破坏.
另一个用于双层DVD的文件显示字幕编码错误,但是当使用该-c:s copy开关时,它还会显示:
Application provided invalid, non monotonically increasing dts to muxer in stream 2: 49 >= 49
av_interleaved_write_frame(): Invalid argument
提前感谢您提供有关如何解决这些问题的任何想法.
(我使用的是Ubuntu,ffmpeg别名是avconv.我知道可以安装真正的ffmpeg,但到目前为止我还没有这样做.)

简短回答:跳到部分完整命令行并ffmpeg从该站点下载.
最初,我计划回答如何做到这一点,avconv因为(a)答案仍然缺失,(b)avconv似乎是今天ubuntu系统的默认设置.然而,目前看起来它太麻烦了 - 至少在我的测试用例中.
ffmpeg设置
既然你要求avconv或者ffmpeg,我刚刚得知这avconv是一个分支ffmpeg(参见这个讨论的答案),我ffmpeg从这个网站下载了当前版本,正如前面提到的答案所解释的那样.Windows版本也可用.对于典型的当前64位Linux构建,直接链接将是此页面.它包含每日构建.所以向下滚动,直到你看到最新,最好的,下载,并解压缩,例如tar xzvf ffmpeg.static.64bit.2014-02-14.tar.gz.静态构建的优点是它具有较少(如果没有)依赖性.拆开tar文件创建了两个新的可执行文件ffmpeg,并ffprobe在当前目录.
基本命令行
现在我们可以使用这个最新ffmpeg版本将其中的所有流复制mymovie.vob*到不同的格式.例如:
./ffmpeg -i mymovie.vob -c:v copy -c:a copy -c:s copy -map 0 mymovie.mkv
这个命令行
-i filename-c:v copy-c:a copy-c:s copy-map 0outputfile让我们展开上面的命令行来解决工具中的一些可能的错误,或者损坏的输入文件,或者只是关于.vob文件的细节.
解决错误 Can't write packet with unknown timestamp
在输入文件-fflags +genpts 之前添加选项.
./ffmpeg -fflags +genpts -i mymovie.vob -c:v copy -c:a copy -c:s copy -map 0 mymovie.mkv
在选项中ffmpeg永远只会影响命名输入或输出文件后,当前选项.这两个选项必须影响输入文件,因此它们必须首先出现.
此错误提示涵盖了此解决方法,并且可能在所有情况下都无济于事.
缺少部分或全部字幕
这是处理.vob文件时非常典型的行为,并在ffmpegFAQ中介绍.视频容器文件类型如.avi或.mp4或.mkv有头(在文件的起始数据)列出文件的所有内容.这使得玩家和转换工具可以轻松了解所期望的数据类型..vob文件没有这样的显式标头.因此,当ffmpeg或avconv开始,他们看的第一对夫妇一千个字节.在vob文件中,字幕可能很晚才开始.在我的测试用例中,第一个字幕在几秒钟后出现,因此工具在启动时看不到它.以下是在这些情况下编码期间的典型示例输出:

可以看出,在实际编码期间发现了新的字幕流.如果尝试添加-map 5选项以包含该流,ffmpeg则会在启动期间抱怨此流编号不存在.
解决方案是告诉ffmpeg分析文件开头的更多字节以便查找所有流.
尝试在输入文件-analyzeduration 1000000k -probesize 1000000k 之前添加选项.
如果仍未找到流,请尝试增加数字.在我的测试用例中,这些数字足够大.然后输出变为:

所有这些选项也受到支持avconv.但是这个工具似乎仍然存在一些字幕的问题.如果您看到此错误:
