I've had success creating Dolby Vision + Lossless Audio TS files with dozens of movies (using eac3to + Yusescope's tool + tsMuxer 04.06) but I have run into an issue with Braveheart that has me stumped. All of the audio tracks, including the TrueHD Atmos track, require a delay of 2,169ms in order to sync up with the video.
When I create the .TS file in tsMuxer with the audio delay set to 2,169ms, my 2019 Shield Pro reverts to HDR and transcodes down to DD+.
When I create the .TS file in tsMuxer with the audio delay set to zero, it plays in Dolby Vision & TrueHD Atmos on my Shield Pro but with the audio clearly a couple seconds ahead of the video.
Has anyone encountered this issue with other movies?
Are there any solutions to tackle this, such as removing the first 2,169ms of the video to make them sync up, or any way to add 2,169ms to the beginning of the .thd+ac3 file?
when you're extracting the bl and el files with eac3to, did you notice any errors? when there's an a/v sync issue after remuxing, it's possible that there may be errors in the original video layers.
No errors during the extraction and the issue appears to exist before that point. When I pull the original M2TS / MPLS files into eac3to and tsMuxer they already acknowledge the required delay:
1: Chapters, 22 chapters
2: h265/HEVC, 2160p24 /1.001 (16:9), 10 bits
3: h265/HEVC, 1080p24 /1.001 (16:9), 10 bits - Dolby Vision Enhancement Layer
4: TrueHD/AC3 (Atmos), 7.1 channels, 48kHz, 2168ms
(embedded: AC3 EX, 5.1 channels, 640kbps, 48kHz, dialnorm: -27dB)
5: AC3, 5.1 channels, 640kbps, 48kHz, dialnorm: -27dB, 2168ms

Automatically sets the delay on all audio files to 2,169ms when imported.
