The manual it should support mkv files with: Video: H.264 /AVC, XViD, MPEG-4 Part2 Audio: HE-AAC, Dolby Digital, MPEG-1 Layer III (MP3) Support .ass subtitles too. So what should i exactly do to be able to play this with the correct formatting and everything else?

Converted the FLAC audio to AAC using this command:

ffmpeg -i CodeGeass01.mkv -c:a libfdk_aac -profile:a aac_he_v2 CodeGeass01_1.mkv

It plays, but without the custom fonts and the subtitle positioning not working either. So it seems i need to make a hardsub video, need to burn in the subtitles. and encode the audio to aac. so how do i exactly do that, with the correct formatting, positioning etc?

Output of ffmpeg -i CodeGeass01.mkv:

so it seems i need to make a hardsub video, need to burn in the subtitles. and encode the audio to aac. so how do i exactly do that, with the correct formatting, positioning etc?

Use the subtitles filter:

ffmpeg -i input.mkv -vf "subtitles=input.mkv" output.mp4

  • You can make a short test by adding the -t option, such as -t 60 for an output limited to 60 seconds.

  • If the fonts are not rendered in the correct typeface then you may have to:

    1. Dump all of the font files with -dump_attachment:

      ffmpeg -dump_attachment:t "" -i INPUT

    2. Then use the fontsdir option in the subtitles filter, or install the fonts to your system.

  • movenc supports ttml since Aug 25: https://github.com/FFmpeg/FFmpeg/commit/e41bd075dd – Gyan Oct 13 '21 at 04:10
  • Thanks for the detailed answer. These are not my videos or subtitles i just downloaded them from different sites. I want to convert it to mp4 to see how it plays on my older televesion. It not supporting mkv format but supports mp4 thats why i want to convert it and preserve the formatting etc. if possible. still a begginer with this. – Norbert Nagy Oct 13 '21 at 20:22
  • I probaly need to convert the audio to aac either way – Norbert Nagy Oct 13 '21 at 20:41
  • Okay after checking the manual it should support mkv files with: Video: H.264 /AVC, XViD, MPEG-4 Part2 Audio: HE-AAC, Dolby Digital, MPEG-1 Layer III (MP3) Support .ass subtitles too. So what should i exactly do to be able to play this with the correct forrmatting and everything else? – Norbert Nagy Oct 13 '21 at 20:57
  • Oh wait it says it support .ass and some more ass external subtiles and XSUB(supports DivX6 generated internal subtitles) as internal subtitle. Hmm. I still want to try maybe it will play just fine. – Norbert Nagy Oct 13 '21 at 21:06
  • It says subtitle and video named the same to be able to play them both automatically, there is no option to select subtitles when im playing a video. Maybe if i try this it hopefully plays and everything will appear correctly. – Norbert Nagy Oct 13 '21 at 21:17
  • I goo to sleep, i will come back sometime tommorow. – Norbert Nagy Oct 13 '21 at 21:26
  • so here is what i did: compilled ffmpeg from source with libfdk-aac beacuse its not supported in the regular package. – Norbert Nagy Oct 14 '21 at 17:35
  • coverted the audio using this command: "ffmpeg -i CodeGeass01.mkv -c:a libfdk_aac -profile:a aac_he_v2 CodeGeass01_1.mkv" – Norbert Nagy Oct 14 '21 at 17:38
  • here is the output: [link](https://pastebin.com/A6nWvjQf) for some reson it reconverted the video too so it took a lot of time. – Norbert Nagy Oct 14 '21 at 17:42
  • maked a new directory on the pendrive an moved the video and the subtitle there with the same name. it plays, but without the custom fonts and the subtitle positioning not working either. – Norbert Nagy Oct 14 '21 at 17:47
  • so it seems i need to make a hardsub video, need to burn in the subtitles. and encode the audio to aac. so how do i exactly do that, with the correct formatting, positioning etc? i think this is my final question sorry for writing so much. – Norbert Nagy Oct 14 '21 at 17:51
  • @llogan ....... – Norbert Nagy Oct 14 '21 at 17:52
  • @NorbertNagy You forgot to map the fonts. Default [stream selection](https://ffmpeg.org/ffmpeg.html#Stream-selection) only picks 1 stream per stream type. So tell it to map everything: `ffmpeg -i input.mkv -map 0 -c copy -c:a aac output.mkv`. If TV doesn't like it see updated answer above for hardsubs. Don't bother with separate ASS file: that suggestion was only for computer based players, specifically for VLC or mpv. I have no idea if TVs follow such convention. – llogan Oct 14 '21 at 18:38
  • Thanks. It seems my tv dont know subtitle positioning the subtitles appear (f/300 "the content of the subtitle") or something like this so i definitely need to go with hardsubs. – Norbert Nagy Oct 16 '21 at 15:32
