   Try adding -map 0 to the arg_override parameter to include all tracks, e.g.:

   split_video_ffmpeg(
       "video.mp4",
       scene_list,
       arg_override='-map 0 -c:v libx264 -preset fast -crf 21 -c:a aac',
   )
   

   Supplying -map 0 will select all tracks (including video/audio/subtitles) which is probably what most people will want, so if that works out I'll look into setting that as the default for the next release.

   If you only want the third audio track, instead of -map 0, specify -map 0:a:2. See the ffmpeg docs for a full description of the -map argument.

   Can you let me know if that works out well for you, and if you think -map 0 is a good default? Thanks!

   I've verified that this seems to work acceptably for a variety of different inputs, so this is likely a reasonable default. Subtitle tracks still won't work with this, but they're ignored as-is so this change won't affect that either (-sn is defined for all ffmpeg commands by default).
