I'm writing a program which extracts images and GPS coordinates from files that were created by car video recorder. In many models it creates two separate files Video and GPS but not all, some recorders write information about GPS – coordinates into video file subtitles. So I Faced with the problem of extracting subtitles from video file. Using such command
d:\test\ffmpeg -i "d:\test\example_1.MOV" -an -vn -c:s copy -f rawvideo d:\test\sub.txt
I got subtitles from file "example_1.MOV", but with another file "example_2.MOV" I got a message "Output file #0 does not contain any stream" Full log is:
d:\test\ffmpeg -i "d:\test\example_2.MOV" -an -vn -codec:s copy -f rawvideo d:\test\sub2.txt

Output file #0 does not contain any stream
I know exactly that this file has a subtitles so I tried to figure out what streams does this file contain using command
d:\Test\ffprobe -show_streams -i "d:\test\example_2.MOV"
i got such information
d:\test\ffprobe -show_streams -i "d:\test\example_2.
MOV"

So ffmpeg does't want to extract subtitles from this file. I'd be glad for any suggestions how to extract subtitles from video
