I don't think so. mkvmerge, and all the mkvtoolnix apps, only deal with MKV container related parts of a file. dovi_tool and jellyfin-ffmpeg7.0.2-4+, and ffmpeg7.1 are the only apps I'm aware of that can remove Dolby Vision from a file.
It is literally a single command to remove dolby vision with Jellyfin-ffmpeg, which I provided in a prior post. You just need to set the actual file path. And you already have jellyfin-ffmpeg installed.

Hi !
It worked for some files but now i get a failure message with converting which i do not understand:
av1_metadata @ 0x615099474780] Codec 'mjpeg' (7) is not supported by the bitstream filter 'av1_metadata'. Supported codecs are: av1 (225)
[vost#0:7/copy @ 0x615099546880] Error initializing bitstream filter: av1_metadata
Error opening output file hdr10_video.mkv.
hdr10_video.mkv then is created with 0 bytes...
this file plays in Browser but not in with internal player..
Ciao Gerd

This happens when there is an embedded image attached. For whatever reason ffmpeg labels that as "video". Your video may not have actually converted.
Change the bsf filter to specify the first video stream, which is USUALLY the actual video. Switch 0 to 1 if the embedded image comes before the video

Hi !
Ok thanks... btw: will the cover than stay in the output file ?

Yes. The image will be in the output file. The "-map 0" command is what determines what is selected. In this case we telling it to map ALL of the streams in the first input file to the output file.
"-bsf:v:0" just changes which video stream to apply the remove_dovi bitstream filter to instead of all of them.
