Hello,
it would be a really great feature, if you could implement a function to show 1 additional piece of information in the mediainfo report. What i mean is the info if the .mkv has Dolby Vision FEL or MEL.
Right now mediainfo only outputs this line:
Dolby Vision, Version 1.0, Profile 7.6, dvhe.07.06, BL+EL+RPU, no metadata compression, Blu-ray compatible / SMPTE ST 2086, Version HDR10, HDR10 compatible
Unfortunately there is no information if it´s DV FEL or MEL (the size or bitrate of the EL).
There is already one tool that can extract this information, but as I understand it not directly, but with a few steps in-between.
There is a tool called Dolby Vision Tool, it´s a bunch of scripts you can find here: https://github.com/DonaldFaQ/DDVT
To get the FEL/MEL information you have to drag and drop an DV-mkv on the Mediainfo.cmd.
What this then does is remuxing and demuxing a 1s RPU-snippet that puts out a .txt in the 2nd step
FFMPEG.exe -i "MyMovie.mkv" -c:v copy -to 1 -bsf:v hevc_mp4toannexb -f hevc - | dovi_tool.exe extract-rpu -o "RPU.bin"
dovi_tool.exe info -s "RPU.bin">"RPUINFO.txt"
Maybe it is possible for you, to somehow include this function in mediainfo? Maybe there is a different technical way to read out this information, if not you can use this tool or the information to recreate this process in mediainfo. I talked to the developer of the DOVI-Tool and he says it´s open source and would also welcome the addition of the FEL/MEL functionality in mediainfo, regardless how you get there from a technical POV (using the DOVI-Tool or find some other way)
This function would be of great interest for many Dolby Vision enthusiasts, so please consider this request.
Thanks alot for your great tool!
