When I use ffmpeg with this command:

$ ffmpeg -i ~/Desktop/The_Karate_Kid_2010.mkv -c:v libx264 -c:a libfdk_aac -c:s mov_text ~/Desktop/The_Karate_Kid_2010.mp4

It works, until this error appears:

Error while opening encoder for output stream #0:2 - maybe incorrect parameters such as bit_rate, rate, width or height

What should I do to fix this? Here is the output:

ffmpeg -i ~/Desktop/The_Karate_Kid_2010.mkv -c:v libx264 -c:a libfdk_aac -c:s mov_text ~/Desktop/file.mp4

dvd_subtitle indicates an image-based subtitle. You can skip it, or overlay it on the video, or convert it to a text subtitle.

To skip it, add -map -s.

To overlay it, add -filter_complex "[0:0]yadif[v];[v][0:2]overlay"

To convert to text subtitle, see https://stackoverflow.com/a/36327919/5726027
