Thanks for this. Fel is discarded on my a95k via app of default media player .Even if it is in dolby vision mode. I have tried every container (DL-ST) exept mp4.

LG B8. Flac works

Ok, try the next version.
line 69 set encode_LL=NO
choices are NO or FLAC or LPCM (default=NO)

I set line 69 to FLAC as you instructed but the worflow 4-3-1 failed with:
[flac @ 0000023f44d84300] encoding as 24 bits-per-sample
[mp4 @ 0000023f44daf880] flac in MP4 support is experimental, add '-strict -2' if you want to use it.
Could not write header for output file #0 (incorrect codec parameters ?): Experimental feature
Error initializing output stream 0:0 --

yes the text appeared correctly.
Im actually really unsure what it's doing to be honest. the tests would indicate so, and the manufactures page says it supports fel, however the word it in a way that makes it sound like they are discarding fel and doing bl+rpu.

are your test sample definitive proof of proper fel support?

Im willing to do any testing you can think of, if you want me to dig deeper.

slightly off topic - getting dolby vision and truehd atmos working at the same time has been a pain. then there's earc flakeyness that really drives a middle finger home XD.

oh I see whats going on. My 2nd version of the fel test is misleading and i took the wrong EL.
please try this one instead and look for the 2nd video in the background like this:

https://drive.google.com/file/d/1rk-quC ... drive_link

Thanks for this. Fel is discarded on my a95k via app of default media player .Even if it is in dolby vision mode. I have tried every container (DL-ST) exept mp4.

Use Emby, if still have problem, I assure you is not the media player. I cast to x800 which cannot process dv in mkv so I always use ts to preserve lossless audio as well. Some DL-ST will freeze black, just keep everything DL-DT.

[DjObama]

I set line 69 to FLAC as you instructed but the worflow 4-3-1 failed with:

Working fine on my end. Are you using your own ffmpeg ? if yes try with the version that comes with my tool pack.

Thank you, YES! That was the case, I had old ffmpeg. I'm happy to report Flac audio works with p7 DT-DL in MP4 container (Edit. On my LG B8)
Compression level 0 you set for flac encode is a good choice, I compared with level 5 on 2,5h movie and the size difference was only 200 mb.

However, the dts-hd ma track got discarded upon conversion, am I missing a setting to keep the original audio track?

[RESET_9999]

yes, it's by design but I can remove that restriction in the next version.
for workflow 4-3-1, remove at lines 7331-7343: if not "%encode_LL%"=="YES"

replace:

For injecting both HDR10+ and DV into the same BL, does it matter which you do first?

[powdeau]

@RESET_9999 Do i need to change something in your DaVinci preset for DV generation in 18.6 or is everything the same?
Now I have these settings:

Thanks!

Hi,
I did some more testing with Flac audio. For some movies after converting trueHD/dts-hd to Flac (i think it applies to lpcm too) the resulting audio track is significantly lower volume. Probably because dts contains metadata that instructs the receiver by how much it should boost the signal and flac/lpcm is just raw audio information. For example Gladiator is a movie for which flac/lpcm is 4,5 dB lower than it could be.
I found a good way to safely increase the signal with ffmpeg. First you have to find by how many dB you can losslessly increase volume with this command:

Code: Select all

ffmpeg -i video.avi -af "volumedetect" -vn -sn -dn -f null /dev/null

This outputs information about how much dB you can increse the volume without going into clipping. For example:

[Parsed_volumedetect_0 @ 0x7f8ba1c121a0] mean_volume: -16.0 dB
[Parsed_volumedetect_0 @ 0x7f8ba1c121a0] max_volume: -5.0 dB
[Parsed_volumedetect_0 @ 0x7f8ba1c121a0] histogram_0db: 87861

Important is only the max_volume
Then use the command to increase the volume by max_volume amount:

Code: Select all

  ffmpeg -i input.wav -af "volume=5dB" output.wav

This command only boosts the overall signal, there is no normalization happening, so it's still a lossless process.

Is it possible to incorporate this process into dovi_scripts @RESET_9999

This may have been answered somewhere within this thread but since makemkv is able to rip the dolby vision layer is it possible to create a dolby vision playable mkv file through mkv or do you have use scripts?

This really depends on the player you plan on viewing your media on. Checkout the signature under RESET_9999.

Hi,
I did some more testing with Flac audio. For some movies after converting trueHD/dts-hd to Flac (i think it applies to lpcm too) the resulting audio track is significantly lower volume.

I'll check it out but I'm pretty sure LPCM is fine.

EDIT: did some tests and the original THD/DTS, flac or lpcm all sound at the same level on my PC.
Anyway, I added -drc_scale 0 in the cli, maybe that will help?

Yes, I checked and on PC there is no problem. However on TV there is a significant diffrence. I just checked another movie - Hero (2002), not even a HDR movie, but Flac plays very quiet compared to dts. Can somebody check the flac playback on their tvs/recievers compared to dts-hd tracks? I read about it a bit and seems that dts format boosts the volume while decoding, but it doesn't happen on pc.
