Command to remux the extracted DV7.EL_RPU file back into the MKV

[cannikin]

Hello! Thanks so much for this script, it's a life saver! :) I'm going to start remuxing my Profile 7 files to Profile 8 for Infuse, and am planning on keeping the resulting DV7.EL_RPU.hevc file around in case support for 7 is ever added in the future, and I can use that extra EL goodness.

What would the process of recreating the Profile 7 file look like? Do I have to first extract a DV8.BL_RPU.hevc file from the the Profile 8 MKV and then combine DV8.BL_RPU.hevc + DV7.EL_RPU.hevc before finally merging that resulting file back into MKV? What's the opposite of this command for merging them back together?

"$doviToolPath" demux --el-only "$BL_EL_RPU_HEVC" -e "$DV7_EL_RPU_HEVC"

Thanks for any help!

Yep, first extract the DV8.BL_RPU.hevc file from the MKV file. Since FFMPEG is unreliable in demuxing DV HEVC files, I'd recommend using mkvextract, like the script does.

Then remux the DV8.BL_RPU.hevc and DV7.EL_RPU.hevc files using dovi_tool's mux command. You don't have to worry about the DV8 RPU present in the DV8.BL_RPU.hevc file, as dovi_tool will automatically overwrite the RPU with the DV7 RPU from the DV7.EL_RPU.hevc file when remuxing.

"$doviToolPath" mux --bl "$DV8_BL_RPU_HEVC" --el "$DV7_EL_RPU_HEVC" -o "$DV7_BL_EL_RPU_HEVC"

Then remux the DV7.BL_EL_RPU.hevc file with your other MKV tracks.

Thanks so much! Here's hoping that one day Infuse supports the enhanced brightness and other goodies in that EL data!
