What am I doing wrong with ffmpeg

JaredBusch

I have some mkv media that I also have Japanese subtitles in srt and English subtitles in ass.

I would like to just mux it in so I don't have to worry about file naming or manually matching things. But when I try to do both at once things puke.

This works

ffmpeg -i "original.mkv" -i "original.srt" \
 -c:s srt -metadata:s:s:0 language=jpn \
 -c:v copy -c:a copy "jpn_sub.mkv"

ffmpeg -i "jpn_sub.mkv" -i "original.ass" \
 -map 0:v -map 0:a -map 0:s -map 1 \
 -c:s ass -metadata:s:s:1 language=eng \
 -c:v copy -c:a copy "jpn_eng_sub.mkv"

If I use -map commands in the first command, it has no errors, and VLC shows a menu item for Japanese subtitles. But they do not display.

ffmpeg -i "original.mkv" -i "original.srt" \
 -map 0:v -map 0:a -map 1 \
 -c:s srt -metadata:s:s:0 language=jpn \
 -c:v copy -c:a copy "jpn_sub.mkv"

This makes no sense to me as anytime you have more than one input, you should use map commands to my understanding.

This is what I thought should work as a complete one line remux.

ffmpeg -i "original.mkv" -i "original.srt" -i "original.ass" \
 -map 0:v -map 0:a -map 1 -map 2 \
 -c:s:0 srt -metadata:s:s:0 language=jpn \
 -c:s:1 ass -metadata:s:s:1 language=eng \
 -c:v copy -c:a copy "jpn_eng_sub.mkv"

Can you have both ass and srt in the same container and have it working? How about converting the srt file to ass and then mux? I believe ffmpeg can convert the subtitles with ffmpeg -i subtitle.srt subtitle.ass

Yes, it works perfectly.

Edit: To be more precise, using the "working" multi-step process above, the mux that adds the ass files shows this. So it seems to be converting it. But I can also force it to srt, and various examples from search results show people mixing srt and ass with no issues.
