The problem of iPhone and iPad subtitles should be solved by mp4box.

RESET_9999, I understand that maybe the question is not at the right address, but I'll ask if you know. There is a problem that could not be solved, I understand that this is some kind of limitation of the LG operating system, if you play DV mp4 movies over the network (DLNA or NAS) with a lot of subtitle tracks, then switching subtitles is not available, at the same time if you run the same movie in mkv over the network, then subtitles can be switched as when connected via usb

You can try

Code: Select all

mp4box -add dv.hevc -add atmos.eac3 -add sub.srt:hdlr=sbtl:lang=eng -new dvh1.atmos.engsub.mp4

Or you can first put an mov_text sub into a mp4 container

Code: Select all

ffmpeg -i sub.srt -c:s mov_text -metadata:s language=eng sub.mp4

And then

Code: Select all

mp4box -add dv.hevc -add atmos.eac3 -add sub.mp4 -new dvh1.atmos.engsub.mp4

Hi, sw5163.
mp4box -add dv.hevc -add atmos.eac3 -add sub.srt:hdlr=sbtl:lang=eng -new dvh1.atmos.engsub.mp4 subtitles no.
ffmpeg -i sub.srt -c:s mov_text -metadata:s language=eng sub.mp4 through mp4box -add dv.hevc -add atmos.eac3 -add sub.mp4 -new dvh1.atmos.engsub.mp4 too subtitles no.
ffmpeg -i dv.mkv -map 0:v? -map 0:a? -map 0:s? -c:v copy -c:a copy -c:s mov_text dv.mp4 subtitles there is.
I'll try it now Subtitle Edit there will be several format files on mp4box.

mp4box subtitles.vtt works iPhone and iPad, but it's a pity there is a minus LG TV, Samsung TV, Android TV, Windows VLC and 321 does not work subtitles.vtt
Most likely mp4box at him mov_text no, need to inform the development mp4box up to update version with support mov_text. Where can I inform those mp4box support?

Well if I can make two there will be subtitles format subtitles.srt and subtitles.vtt now everyone has support iPhone, iPad, LG TV, Samsung TV, Android TV, Windows VLC and 321 everything is OK.

I don't know, I hate the MP4 container.
TS container is 10times better for DV. Have you tried it with external SRT ?

I would love to do it in TS, but srt external subtitles are only suitable when it comes to one track, and if there are many of them? Therefore, this solution is not suitable.

No you can add as many as you want with PLEX

RESET_9999, unfortunately, this is also not an option, the task is to have everything already inside the container, since this is not for personal use, but for public use, for myself I can do at least in mkv dv and watch from the media player)

Just for fun, I thought I would try generating DV metadata for the Hitchcock film "Rear Window" using the new 3-1 frame by frame option. This movie was only released in HDR, with no DV. The film is in 1:66:1 (5:3) aspect ratio, so am I correct in entering the L5 offsets as:
Left L5 offset 120, Right L5 offset 120, Top L5 offset 0, Bottom L5 offset 0
?
Thank you so much!

I am right that dv p7 mel, converted to p8.1
, will have a better output on a c1 internal player versus original p7 mel on sony x800m2? Because of l1 and l2 metadata?

you have to measure the black bars manually in Avspmod. I didn't generate the RPU I have but it's set to:

Code: Select all

          "Level5": {
            "active_area_left_offset": 124,
            "active_area_right_offset": 125,
            "active_area_top_offset": 0,
            "active_area_bottom_offset": 0
          }

I am right that dv p7 mel, converted to p8.1
, will have a better output on a c1 internal player versus original p7 mel on sony x800m2? Because of l1 and l2 metadata?

The metadata response will be slightly different but I really don't know which one is more accurate.
If you have a good audio system, I would not sacrifice lossless audio.

Thank you !!
