3rd video stream, all audio streams, no subtitles. This example uses negative mapping to exclude the subtitles. Ffmpeg -i input -map 0:v:2 -map 0:a -map -0:s -c copy output Choosing streams from multiple inputs. All video from input 0, all audio from input 1: ffmpeg -i input0 -i input1 -map 0:v -map 1:a -c copy output. Does any body know how to extract subtitles from a dvd or a vob file with ffmpeg? I could get fine working.sub and.idx files via mencoder command: mencoder dvd://1 -vobsubout subtitle -vobsuboutindex 0 -vobsuboutid it -sid 10 -nosound -ovc copy -o 1.avi but i get a huge temporary file (1.avi) witch is the entire video stream. FFmpeg can easily extract embedded subtitles from videos. This command will grab the default subtitle track and export it as a srt file: ffmpeg -i inputfile out.srt What if we want to get a different subtitle?
SubStation Alpha (or Sub Station Alpha), abbreviated SSA, is a subtitlefile format created by CS Low (also known as Kotus) that allows for more advanced subtitles than the conventional SRT and similar formats. It is also the name of the popular, now discontinued tool used to edit subtitles.
Using ffmpeg to add srt subtitle files to mp4 files A workaround to quicktime's lack of srt file support After a long and delightful time using Elementary OS as my primary OS, I’ve had to switch to Mac OS for work and also due to my computer spontaneously combusting. I also extract the subtitle track to a text file with a.ass extension, like so: ffmpeg -i tt.mkv -scodec copy script.ass. Ffmpeg is smart enough to know that you can’t put video or audio into a.ass file so it drops those and we’re left with just the script. After that, I made my changes to the script and needed to mash it all back into.
This subtitle format is frequently used in anime fansubs, either to overlay subtitles onto video while it is being encoded (hardsubbing), or to store subtitle data alongside video data, often in a Matroska (MKV) container (softsubbing). It's not commonly used professionally except for Crunchyroll.
The current version of SSA is v4.08. There are many freeware and open source subtitling applications that support the SSA format.

A basic SSA subtitle:
Advanced SubStation Alpha[edit]
Advanced SubStation Alpha (ASS) is a script for more advanced subtitles than SSA. It is technically SSA v4+. It is able to produce anything from simple texts to manual graphic editing used in karaoke. There are few programs designed to create these scripts.The main feature of ASS is it has more specifications than normal SSA, like in styles programming.For example, the above script changed into ASS:
