我需要从电影文件中提取隐藏式字幕信息,我已经尝试ccextractor但似乎没有用.
我已经捕获了一个视频流(其中包含隐藏式字幕)并保存到文件然后我运行ccextractor...但它找不到任何东西!
我的视频示例如下:

第一次尝试:
cvlc -I dummy v4l2:///dev/video1:width=720:height=480:norm=ntsc:standard=ntsc:pixelformat=2:aspect-ratio=4\:3:channel=0 --sout "#transcode{vcodec=mp2v}:standard{access=file,mux=dummy,dst=gsd.mpg}"
