Well, I've made several tries with different methods. As we don't have any good DTS encoder, my goal is to produce an AC3@640kbps file directly from AVS script, without create a big WAV file. I can now do it with BeHappy, using Aften or ffmpeg. How can I hear if the created AC3 file match perfectly the source ? madshi, what are your Aften settings ant what is your Audacity method to compare the files ? |

I think the time difference is caused by drop-frame timecode vs non-drop timecode. So nothing wrong at here. You may find this article helpful for understanding. http://www.csif.org/html/dropframe.html |

I finally decoded DD+ (as .wav mono ) with sonic decoder 4.2->avs->behappy... And it appears sound ran slightly faster than images (@ 23.976). Choosing 24 fps for video didn't help either, so I toyed with timestrech dsp available via behappy, and finally found the perfect stretching value : 24.000 -> 23.990 to keep the A/v synched all along the film Don't ask me why... Now, I'm working on "the thing" ... and then again, audio decoded (with Aften this time) runs faster. For this one, the correct audio stretching is 24.000->23.988 to have a constant sync with video (still encoded @ 23.976) so weird... Of course, I'm talking about progressive decay in all cases, nothing to do with the 100-150 ms a/v starting delay Last edited by juhu; 3rd March 2007 at 04:35. |

Google for two keywords: "behappy" and "avisynth". It's 99.9% that you'll find BeHappy - Avisynth-based audio encoder rather than something else
Awesome work around here! Following guides from this thread i was able to decode and reencode Riddick HD-DVD into x264+AAC (only stereo ATM) (essentially, reencoded 16-GB VC-1 stream into 14-GB x264 stream (0.99 SSIM), so with AAC audio tracks it will fit on 15-GB HD-DVD disk). While i have some problems with fps, resync, decoding (from my usual playing toolkit [MPC/ffdshow + VLC + MPUI] no player is able to play this movie properly - either it hungs on some moment, or plays video faster than 23.976 fps, or can't open mp4 container) - it's all minor technical issues and could be solved. Currently i'm trying to smooth the whole process and to make it more open/free (i.e. without expensive software filters/decoders). Nevertheless it works. We can decode and reencode HD-DVDs! CooL!

I have the same problem with using BeHappy that I had when I originally tried to create a wav directly with the Sonic Audio Decoder, only. Namely I got 2 good channels and 4 bad channels. The bad channels looked like loud noise to me with a tiny bit of audio information in the first 1-3 seconds of the track. Adding ffdshow to the graph behind the Sonic HD Audio Decoder solved the problem for me when outputting a wav file through "WAV Dest -> FileWriter". Unfortunately BeHappy doesn't work with a graph "DTS/AC3 Source -> Sonic HD Audio Decoder -> ffdShow". It complains about not being able to find a class or something like that. If I remove ffdShow from the graph, BeHappy works, but then only 2 channels are good.
Just as a warning to you guys. If it works for you that way, just BeHappy about that. But better make sure that you check whether all 6 channels are good. You can check that by converting the final AC3 file to 6 mono WAV channels by using Tranzcode and then by looking at the WAV files in Audacity. |

@Pelican9,
here's a list of little bugs I found in your great EvoDemux tool: (1) If I open the "file open" dialog to load a new EVO file - but abort the "file open" dialog, the EVO is read again. This should happen, aborting the "file open" dialog should behave as if I didn't even open the dialog in the first place. (2) If I delete the EVO file which is currently selected by EvoDemux and then open the "file open" dialog and then abort the "file open" dialog, there's a crash and afterwards all buttons are disabled. (3) If I rebuild the EVO with only 1 audio track, the other audio tracks are still listed in the EVO. It seems that their content is removed, but they're still listed in the header or something like that. (4) If there's some kind of action running and I try to close the whole program, the closing stalls until I press the "Cancel" button. Trying to close the whole program should either automatically cancel the running action. Or alternatively you could open up a MessageBox asking whether the running action should be cancelled. Keep up the great work! Thanks also to Ron/drmpeg for the original demuxing code. P.S: Does EvoDemux support being controlled by command line parameters yet? That would help a lot in automating things. |

"VOB number 4 contains 2 video , 5 audio and 4 subpicture streams." It contains three DD+ tracks and one Dolby TrueHD track. I select the main video stream, one of the DD+ tracks, the Dolby TrueHD track and a subtitle and press rebuild. The new rebuilt file contains all the selected streams (as it should) but if I run EVOdemux on the new file it cannot find the Dolby TrueHD track but it's there as the file size is much larger then if I do not select it. |

as noticed 2 posts above by ZGX, evodemux gives curious reports on rebuilt .evos
Once again : Casablanca. Builiding one single evo with the 2 parts gives me this : -------------------- Opening file Feature_1_Feature_2.rebuilt.EVO File size: 13851 Mbytes. VOB number 4 contains 1 video , 5 audio and 4 subpicture streams. PTM of first video frame = 00000D91 PTM of last video frame = 105CFFB1 Duration = 0:50:50.297 VC-1 video stream 0 found! First PTS = 00000D91 Substream id = 55 Sequence Header found 0 frames before first I-frame Advanced Profile Level = 3 Chroma Format = 4:2:0 Size = 1920x1080 Display Horizontal size = 1920 Display Vertical size = 1080 Aspect ratio = 1:1 (square samples) Frame Rate = 23,976 (24000/1001) (audio/sub parts removed) 147590 counted frames (1:42:35.733) in video stream 0. 73134 calculated frames. in other words, it gives me stats from the first part, even after appending the 2nd (apart from the counted frames, but we know it's much less useful than calculated frames...) |
