Well, the bad news is I just built a new PC - got everything installed so eac3to can do it's thing ....and I'm STILL getting the "The program channel mapping changes in the middle of the stream" error message with the Mr & Mrs Smith Blu-Ray.
Just to be absolutely sure I'm going to let it go through the process of trying to create the mkv, flac chapter & sup files, but I'm pretty sure I'm going to get another abort. I will post the log when it's done aborting. |

The problem was brought up with two different movies. I got one sample - with which the problem did not occur. After that the person who reported the problem said that the problem was caused by him using the wrong playlist (which combined some SD and HD m2ts parts). I never got a sample with which I can reproduce the problem. Without a sample I can't do anything...

Some unanswered questions ;-):- 1. Are you planning to add option to demux TrueHD & Core seperately? 2. Are you planning to add feature to combine already seperated Core & TrueHD Track by Eac3to? Regards, Sehgal |

Regarding the Mr & Mrs Smith problem... I have the UK version of the Blu-ray and I don't get any errors. I am also quite possitive the US blu-ray works fine cause I know a lot of people have it and never heard a complain.

Madshi,
I provided the last sample (which unfortunately didn't fault for you). I'm happy to provide you another sample (perhaps a larger sample? - the last one was around 50Mb) but if the same file is causing issues with me, and not with you would you have any clue as to where the problem might lie, if not with the file itself? In the meantime, I'm going to try to create a larger file (say around 100Mb) and upload it for you in the hopes that THIS one will fault for you. BTW...it's definitely the zone A disk I have here (US). Here's the eac3to log file - not that it'll help much. Thanks! BTW....if you need a larger sample again, just let me know.

When you test the sample, make sure you copy it to a folder separate from the original Blu-Ray folder structure. E.g. copy it to the desktop and let eac3to check it there. Quote:
Again TrueHD has no core. I may eventually add a feature to create an interweaved TrueHD+AC3 track for Scenarist muxing. |

Trying to remux The Game Plan with eac3to:
eac3to bd-tgp 1) 00139.mpls, 2:07:03 [92+1+93+3+94+5+95+7+96+9+97+11+98+13+99+15+16+100+18+101+20+102+22+103+24+10 4+26+105+28+106+30+107+32+108+109+35+110+37+111+39+112+41+113+43+114+45+115+47+1 16+49+117+51+118+53+119+55+120+57+121+59+122+61+123+63+124+65+125+67+126+69+127+ 71+128+73+129+75+130+77+78+131+80+132+82+133+84+134+86+135+88+136+90+137].m2ts - h264/AVC, 1080p24 /1.001 (16:9) - RAW/PCM, English, multi-channel, 48khz - AC3, English, multi-channel, 48khz - AC3, English, multi-channel, 48khz - AC3, English, multi-channel, 48khz - AC3, English, stereo, 48khz The result is a perfect mkv of the video. But audio is screwed up. The first chunk (a few minutes) of audio is repeated several times during the first 15 minutes. The disney theme cuts in all over the place. |

P.S: I guess eac3to asked you to rerun the command line to fix audio overlaps? Did you do that rerun? If so, could you please check if the problem already occurs before the rerun or if it is introduced by the overlap fixing? Thanks! |

I'm still testing, but I may have accidentally stumbled onto a solution for getting Mr & Mrs Smith to work.
It's a little left field, but it seems to have worked - I'm just muxing the files together now...will report back soon. |

Think of each letter as ~2min audio Correct audio: a-b-c-d-e-f-g-h-i-j-k-l-m eac3to audio: a-b-c-a-e-f-a-h-i-b-k-l-b I will try again and check before rerun (overlap fixing)... Last edited by rickardk; 22nd August 2008 at 12:42. |

Sowwie, my typo mistake.. i meant, Are you planning to add option to not to demux TrueHD & AC3 seperately? & Second was to Combine TrueHD+AC3 file that already being seperated by Eac3to? In general term, we use Core for that AC3, that's why got confused. :-) |

OK - it's now confirmed - I can get eac3to to produce a perfectly working version of Mr & Mrs Smith, but what I had to do was a little weird.
For this particular movie, the whole movie is contained within the one m2ts file. First off, I removed 00001.m2ts (the main file) from the stream folder in order to cut it and make Madshi a sample, but when I tested the sample, the error wasn't showing any more. I put it back into the stream folder and the error came back. If I pointed eac3to exactly to the file within the STREAM folder (instead of just the title's folder - in this case MRMRSSMITH) no errors were displayed, but there was no option to rip the chapters either. Just on a hunch I removed EVERY OTHER m2ts file from the stream folder and put them somewhere else. Then I pointed eac3to back to the title folder (MRMRSSMITH). Eac3to produced the full list of video/audio/chapter/subtitle files without showing any error messages at all, so I let eac3to go - it produced the mkv file from the h264 video, the flac file from the DTS MA, the chapters file & the english sup file (I usually do this just in case it's a "forced subs" track) and it went all the way to completion without aborting. After using MKVMerge to put the audio & chapter files back in, and testing it, it has all worked perfectly. I don't know why eac3to was producing that particular error on this particular disk, but hopefully there's something in my explanation that Madshi might be able to use to find what the problem was. If you need me to do any further testing, I still have all the files on the PC and will keep them there for a while. |

@madshi
we are talking a lot about bit-perfect transfer here when it comes to audio, but what about the same thing with video, e.g. raw h.264 stream to MKV and vice-versa? how i test: eac3to file.m2ts raw_1.h264 eac3to file.m2ts file.mkv mkvextract file.mkv to raw_2.h264 mkvmerge raw_1.h264 to file2.mkv mkvextract file2.mkv to raw_3.h264 my expectation was that raw_1.h264, raw_2.h264 and raw_3.h264 are exactly the same or at least have some small differences in headers or something, but it turns out that they are all different and when compare them with hex editor the differences are very huge. so, why is that and is it OK?

Thanks, that will be helpful. Quote:

IMHO MKV demuxers should add AUDs back into the stream. Should be rather easy. Unfortunately mkvextract doesn't do that. |

raw_1.h264 (217 bytes): raw_2.h264 (242 bytes): raw_3.h264 (263 bytes): so, we have about at least 20% difference between raw_1.h264 and raw_3.h264. it's too much, isn't it? Last edited by xkodi; 22nd August 2008 at 15:24. |

Generally when testing bit perfectness with video you should test more than just 200 bytes. Try 20MB at least. Last edited by madshi; 22nd August 2008 at 15:31. |

Bro i spent two whole days working on mkv & h.264 & vc-1, few wks back// and i came to conclusion that once raw VC1 or H.264 went to MKV, u can NEVA get to see exact original size. No PERFECT container for timebeing. Tools i used - VC12AVI, MKVMerge, Eac3to, Yamb, TSMuxer, TSRemux. |
