For keeping more channels (up 6.1 is possible with current decoders) you need to decode and re-encode the track. |

Well, there's no info about # of channels the truehd decoders output.
But, since we have a free truehd decoder, if it not supports more than 5.1. channels, it can in the future. I believe it would be easy for the developers to update the libav decoder with 6/7.1 support. All they 'll is such sample streams. Do you actually have a truehd track with more than 6 channels? |

Sorry for the late reply.

BTW playback is improved using ffdshow as VC1 decoder. In fact it doesn't matter that much whether the libav codec or the WMV codec in ffdshow is used. The green garbled mess, that starts after a few seconds, is absent now. Audio is heavily distorted though. Same result with a total Sonic graph. Good video, bad audio. Converting eac3 to ac3 with eac3to results in a problematic ac3 track. So lots of things happening here. You bet! (for most of the titles ) Here is a sample from Robin Hood. Using Haali splitter video seems fine, however audio is distorted. Converting the eac3to track to ac3, this ac3 track has lots of strange noises in it. Here again the sample plays back fine in PDVD. http://www.sendspace.com/file/9nw2a4 Here is a sample from Unforgiven: http://www.sendspace.com/file/bwuj9r Using Haali splitter and MS VC1 decoder, video is heavily distorted. Plays back fine in PDVD and using a Sonic chain in ZP. The video mess is not always present, some pieces of the movie are fine. Using ffdshow as VC1 decoder, there is no video distortion but video has strange speedups from time to time and audio goes wildly out of sync. See this sample for the speedup. http://www.sendspace.com/file/8s4vtx Eac3to only sees the VC1 track and not the audio tracks in the original evo and the first sample. However the speedup sample coming from the middle of the movie gives the correct tracks with eac3to. So there might be some corruption at the beginning of the movie. |

btw. I noticed that for some of the last times I converted a blu-ray LPCM track to flac I didnt get this message "this is problably a blu-ray (LP)PMC track. will re-map channels accordingly" or what it was. so is this normal, is everything still ok (I didnt experience any errors at plaback at least (on a 2 speaker system))?

Just tested the latest version on a pair of EVOs that worked with version 2.14 (Charlie and the Chocolate Factory), and I get an error "The VC-1 pulldown remover didn't receive the format information."
Any ideas? Cheers, Beastie. PS I'm afraid that I can't upload a sample for a while, I'm on a temporary dial-up connection and it's sloooow |

P.S: Cutting the first few MBs of the EVO file is not as easy as it might sound. You have to cut at the right place, sadly... |

The Robin Hood sample seems to behave just fine with the latest eac3to build (v2.16) with both Nero and libav decoders. No problems with the audio tracks in that sample, as far as I can see/hear. Tested only audiotrack 1, though. Quote:

v2.16 breaks file recognition
I installed v2.16, I just extracted to the v2.14 directory and allowed overwrite all, then eac3to -test showed nero, sonic and MKVsplitter not installed. MKVtoolnix installed. OK so just reinstall the programs I thought.
Uninstalled the Matroska Splitter rebooted re-installed the splitter, still not recognized. So I just extracted v.2.14 eac3to.exe and allowed it to overwrite v.2.16 eac3to.exe only and changed nothing else, now nero, matroska and sonic are recognized again. It seemed to me that after re-installing Matroska and it not working that it was pointless to try the others. So what is the proper upgrade procedure to avoid this? |

eac3to v2.17 released
http://madshi.net/eac3to.zip Code:
* fixed VC-1 pulldown removal * VC-1 pulldown removal must now be activated by the new option "-stripPulldown" * improved VC-1 gap/overlap detection * new option "-ignoreGaps" disables VC-1 gap/overlap detection * libav E-AC3 decoder background decoding removed again So please test again with some VC-1 movies. Please check whether eac3to posts any warnings about gaps/overlaps in the video track. Hopefully not. Also, does anybody have the USA HD DVD of Phantom of the Opera? I really would like to have that tested cause it didn't work with v2.14, but should work now with v2.15-17. |
