I'm no FFmpeg expert, but from what I can find this probably means certain characters can't be converted to mov_text. I'm not sure though.

I don't have any experience with a Raspberry Pi, but I can't believe putting both -c:v h264_mmal and -c:v h264_omx in your commandline would work.
Except for the video-bitrate you're not changing anything else, so why not do a streamcopy instead?Also the order of your options matters. Could you try:

ffmpeg -ss 00:04:45 -i 'Beck_ _je for _je (4).ts' -to 00:05:00 -map 0:0 -map 0:2 -map 0:3 -c copy -map 0:1 -c:s mov_text -metadata:s:s language=dan 'Beck Øje for øje (4).mp4'
