–embed-subtitles
embedding of subtitles is not supported. Please use another tool to add them yourself. You allready have ffmpeg so you could run:
for one language:

replace the language string with the ISO 639-2/B language code for your subtitles.
for several languages at once you need to use map:
ffmpeg -i input.mp4 -i input1.srt -i input2.srt -strict -2 -c copy -c:s mov_text -map 0 -map 1 -metadata:s:s:0 language=lang1 -map 2 -metadata:s:s:1 language=lang2 output.mp4
