Could you give an example of the usage of "-forced_subs_only" (didnt't
found documentation) ?

Here is the command line I use to encode my BD :

ffmpeg -i "file.m2ts" -filter_complex "[0:v][0:s]overlay,scale=1280:720[o]"
-map [o] -map 0:a -aspect 16:9 -c:v libx264 -preset slow -crf 18 -profile:v
main -level 31 -pix_fmt yuv420p -r 24 -c:a aac -strict experimental -b:a
160k -ac 2 -ar 48k "file.mp4"
