I have an MKV that I am using to create a DVD using DeVeDe
The MKV has embedded subtitles in vobsub format, which DeVeDe does not support (or bugged, not sure)
I decided to burn the subtitles to the output using the extra ffmpeg parameters option, which I took from here:
https://trac.ffmpeg.org/wiki/How%20to%20burn%20subtitles%20into%20the%20video
So I've updated to the latest ffmpeg and added the following extra parameters:
-filter_complex "[0:v][0:s]overlay[v]" -map [v] -map 0:a
So the complete command is:
ffmpeg -i ~/Input.mkv -vf scale=720:412,fifo,pad=720:576:0:82:0x000000 -y -target pal-dvd -sn -acodec copy -g 12 -t 60.0 -ac 2 -s 720x576 -threads 3 -trellis 1 -mbd 2 -b 2616000 -aspect 16:9 /var/tmp/previewfile_01_01.mpg -filter_complex "[0:v][0:s]overlay[v]" -map [v] -map 0:a
But out of DeVeDe I get:
[AVFilterGraph @ 0xa744ca0] No such filter: '"'
Running it in a shell gets:
Output pad "default" with type video of the filter instance "Parsed_overlay_0" of overlay not connected to any destination
The documentation for the filter is here: http://ffmpeg.org/ffmpeg-filters.html#overlay-1
But I can't make head or tail of it.
The -map parameters a mystery as well.
Here's the details the streams:

How to I burn that subtitle stream to the output video?

The problems
I see several issues with your command:
All filtering should be within one filtergraph.
You have many contradicting commands: for example you use the
scale
video filter, then you use-target
which will scale, and you use-s
which will also scale. You use-acodec copy
to stream copy the audio, but you also include-ac 2
to force stereo. These are mutually exclusive so something is being ignored.You placed options after the output. I'm not sure how ffmpeg will interpret that. Option placement matters.
Example
Note
Your video is 720x336, but your subtitles are 720x480. You may have to use
crop
on the subtitles before usingoverlay
:Or alternatively you could use a negative value on the
y
coordinate inoverlay
:
