MKV to MP4 creates redundant menu stream

[unknownsoldierX]

I have a batch of MKVs I'm trying to convert to MP4. The original MKVs have a single menu stream, but the MP4s created by FFmpeg have a second, redundant menu.

I'm not sure if this will present any playback issues on any devices, but it's annoying and I'm curious what's causing this.

ffmpeg.exe -i "S03E01- Chapter 27.mkv" -acodec copy -vcodec copy -sn "S03E01- Chapter 27.mp4"

It shouldn't be a problem. It reportedly menu 1 is for MAC.

How much it bothers you. Demuxer track on the prime factors and muxer in mp4box.

What do you mean by 'MAC'? As in Apple?

Is there no way to have ffmpeg put output just the original menu? This happens with every MKV that has a menu that I convert to MP4.

First Menu #1 is for standard Quicktime
Second Menu #2 is for standard Nero

You can turn off chapter Nero. Quicktime is for FFmpeg priority.

[unknownsoldierX]

Thanks. I hadn't seen any explanation anywhere. I've added -movflags disable_chpl to my command and now there is only one chapter stream. I've read that Nero chapters can cause problems, and there seems to be no need for them anyway.

You seem pretty knowledgeable, so I'd like to ask you another question. Is there a way to set a flag to have subtitles to be enabled by default?

I have some MKV files with subtitles I'm converting to MP4 containers. When I open the MKV files with VLC or whatever, the subtitles are enabled automatically. I convert them to MP4, and when I open the MP4, I need to go into the menu and enable subtitles.

I don't know how works the VLC player. I have the MPC-HC. The functions default/forced on or not enabled do not affect the display of subtitles. It isn't possible not to display subtitles in MPC-HC. The first subtitle is always on, the rest off. You can change the track 'default' of the function 'disposition', but my player doesn't see it. The player doesn't respond to function container MP4 'default/forced'.
The 'metadata disposition:forced' is dead function in ffmpeg. Ie. which isn't to be typed track is enabled in MediaInfo. It seems that the mp4 container no function 'forced'.
The function "-disposition:3 forced" is only matroska and bluray. All subtitle tracks are then turn on in the "default". This option isn't recommended. It must be installed LAVfilters.
The function "-disposition:3 default" work used in the player MPC-HC v1.7.10.172 with container Matroska.
