There is several Blu-ray discs which use this channel setup. If you need more samples, let me know.

Issue with E-AC3 tracks?
Hi!
Whenever I try to demux a BluRay (m2ts files) containing an E-AC3 (7.1) audio track, eac3to fails. It can not even extract the core and it just aborts. See the log: eac3to v3.34 command line: "F:\Clown_BD\eac3to\eac3to.exe" "V:" 1) 6: "T:\Clown_BD\Audio_6_German.AC3" -progressnumbers -LOG="T:\Clown_BD\LOGS\eac3to_PASS3_LOG.LOG" ------------------------------------------------------------------------------ M2TS, 1 video track, 6 audio tracks, 7 subtitle tracks, 1:45:00, 72p /1.001 1: Chapters, 28 chapters 2: h264/AVC, 1080p24 /1.001 (16:9) 3: DTS Master Audio, English, 7.1 channels, 24 bits, 48kHz, dialnorm: -3dB (core: DTS, 5.1 channels, 1509kbps, 48kHz, dialnorm: -3dB) 4: DTS Hi-Res, English, 5.1 channels, 2046kbps, 48kHz, dialnorm: -3dB (core: DTS, 5.1 channels, 1509kbps, 48kHz, dialnorm: -3dB) 5: AC3, English, 2.0 channels, 320kbps, 48kHz, dialnorm: -28dB 6: E-AC3, German, 7.1 channels, 896kbps, 48kHz, dialnorm: -27dB (core: AC3, 5.1 channels, 512kbps, 48kHz, dialnorm: -27dB) 7: E-AC3, Italian, 7.1 channels, 896kbps, 48kHz, dialnorm: -27dB (core: AC3, 5.1 channels, 512kbps, 48kHz, dialnorm: -27dB) 8: AC3, English, 2.0 channels, 320kbps, 48kHz, dialnorm: -27dB 9: Subtitle (PGS), English 10: Subtitle (PGS), German 11: Subtitle (PGS), Italian 12: Subtitle (PGS), English 13: Subtitle (PGS), German 14: Subtitle (PGS), Italian 15: Subtitle (PGS), English [v02] The video bitstream framerate field doesn't seem to match the timestamps. <WARNING> [a06] Extracting audio track number 6...

When demuxxing the other tracks, they are mostly damaged as well (especially the subtitle tracks) - this only happens when there is such an E-AC3 track present in the m2ts file. Cheers! |

BTW, I forgot to specify that if your M2TS is multi-angle, you have to specify the angle to demux with this (assuming angle 1): Code:
path\to\eac3to.exe V:\BDMV\PLAYLIST\00200.mpls 1) 10: english1.sup 11: english2.sup

This is right, if you have a single forced subtitle at the end of the stream / film, you can not recognize it at beginning of the stream, so you have parse the whole stream to find it. If you dont have some addition file which contains a listing of all streams, you have to decode the complete stream.

The NEW DD+ @ BD have 4 (EAC3) Surround Ch's that replace the 2 Surrounds of the 5.1 AC3 Core Track when 7.1 DD+ is playing !

After a stalled start with HD-DVD there's no doubt that Dolby Digital Plus is back and expanding it's feature-set, especially as more streaming services embrace object-based (Atmos) audio.
With Atmos in mind... Have any of you guys downloaded Dolby's 7.1.4 and 9.1.6 (DD+ with Atmos) samples, that were muxed into the .mp4 container?

All that said, FFmpeg should be able to handle this very soon. The patch is basically ready for inclusion. It should come to FFmpeg based players and tools then eventually.

Only loosely related: After more than a year, the ffmpeg trac ticket #3595 is active again ... its title got renamed.

Isn't the video for both eyes as its own track? IIRC the left eye stream is the "main" one to demux.

That is the case for 3DBDs, always. Although left/right could be swapped and the AVC stream actually be the right eye, but there is always one main AVC stream you can just take without the MVC stream to get 2D.

To grab the 2D movie, you have to demux the MPLS, and select the AVC video stream and the audio and subtitle streams you are interested in, and drop the MVC. If you want to demux directly the M2TS file(s), you have to locate the one that contains the AVC stream. It's easy with a good player. The M2TS files with the MVC stream cannot be played directly.
The command to demux is exactly identical to the command to demux a 2D BD, just omit the MVC stream. But personally, I would use tsMuxeR instead of eac3to to demux a BD. It has a good GUI, easy to use.
