I want to convert this video with ffmpeg keeping all subs with their style.

[Unknown01]

I have this video:



It has multiple subtitles ASS/Vobsub (and attached files for sub style), audio in FLAC, DTS, Vorbis and etc.

I want to keep absolutely everything sub-related as is (their fonts attachments, the color, style, etc), but encoding the video to h264 and all the audio streams as Vorbis in FFMPEG. What syntax should i use?

Use clever Ffmpeg-GUI.
Drag & drop your movie, click main, click encode videostream, set resize or keep size,
set x264 as encoder, make your settings and click encode.
If finished, click multiplex, the new created videostream is shown in green, deselect the original videostream (the blue one) and click multiplex.
Done

I see...i'll check it out.

I was hoping for a FFMPEG syntax so i could study it to see why what i tried did not work.

Actually, i can't get it working with clever Ffmpeg-GUI, it doesn't process it correctly.

Anyone knows a FFMPEG syntax to keep all the subtitles, all the audios, all the attached files (fonts, etc) and all the subtitles style (size, color and etc) while changing the video stream encode?

Could you specify the problem?
What exactly isn't correctly processed?

Unless I am mistaken, you don't need to do anything. Notice the codec says "AVC"? AVC == H264.
Similarly, HEVC == H265.

If there is something you need to do, which I doubt but is possible if your player app is real picky about codec fourcc codes, is edit the codec fourcc code/tag from AVC to H264. Which any hex editor should be able to do in 5 seconds.

If that isn't it, look more at the details of the codec: perhaps it is 10bit, or perhaps the header stripping is affecting playback recognition.

FFMPEG uses the map parameter to process all streams, if there is only one input file it would be "-map 0".

The -c parameter specifies which codec to use to process them, if you don't want it to convert them then -c copy, but this would not process anything. I guess you already use the -c parameter somewhere to indicate the video codec. To copy only the audio and subtitle streams would be "-c:a copy -c:s copy", the attachments cannot be converted so it always copies them. Now to specify the audio streams to convert, as far as I can see they are the first 2 audio streams, it would be "-c:a:0 libvorbis -c:a:1 libvorbis"

The final command would look something like this

ffmpeg -i "input.mkv" -map 0 [your_video_parameters]  -c:a copy -c:s copy -c:a:0 libvorbis -c:a:1 libvorbis "output.mkv"

But this is just an explanation, don't expect the command to work as-is
