For your 1st question...
If you run eac3to and give it a hd dvd folder (either main or hvdvd_ts) it would list all titles found in the xpl file. It is very easy to get an idea of what's into the hd dvd. After that you can "add" a title # in the command and get more detail description of the contents. E.g: Code:
eac3to "G:\Galapagos HD DVD 1080p VC-1 DD 2.0" ------------------------------------------------------------------------------ 1) EPISODE1.EVO+EPISODE2_1.EVO+EPISODE2_2.EVO+EPISODE3.EVO, 2:26:44 "PlayAll" - VC-1, 1080i (16:9) - E-AC3, 2.0, 48khz 2) EPISODE1.EVO, 0:49:02 "Episode1" - VC-1, 1080i (16:9) - E-AC3, 2.0, 48khz 3) EPISODE2_1.EVO+EPISODE2_2.EVO, 0:48:55 "Episode2" - VC-1, 1080i (16:9) - E-AC3, 2.0, 48khz 4) EPISODE3.EVO, 0:48:47 "Episode3" - VC-1, 1080i (16:9) - E-AC3, 2.0, 48khz 5) PLANETEARTHTRL.EVO, 0:01:02 "Planet Earth Trailer" - VC-1, 1080p (16:9) - E-AC3, 2.0, 48khz Code:
eac3to "G:\Galapagos HD DVD 1080p VC-1 DD 2.0" 3) ------------------------------------------------------------------------------ EVO, 1 video track, 1 audio track, 1 subtitle track, 0:48:58 "Episode2" 1: Joined EVO file 2: Chapters, 6 chapters with names 3: VC-1, 1080i60 /1.001 (16:9) 4: AC3, 2.0 channels, 448kbit/s, 48khz, dialnorm: -27dB 5: Subtitle, English EDIT1: I was more detailed, therefore 2nd... EDIT2: Since i started, i can't stop... Code:

Extracting primary video track... Muxing video to Matroska... Extracting audio track number 4... Removing dialog normalization... Extracting subtitle track number 5... Creating file "galapagos.ep2.ac3"... ... ... ... eac3to is great!!! No need to type any input files anymore. All being done automatically. And it's a command line program. madshi you are my hero!!!

Tried it and it works, thanks. Is there any way to specify a path for the log file, rather than it going in the eac3to program directory? Small thing I know.

Thanks to both of you. I was aware of the xpl generated listing and of the ability to extract without refering to the evo files, just not the ability to list the streams using "eac3to z:\ n)". I really did think I had tried that but clearly not! I have amended the guide.
I'd appreciate any comments/thoughts on points 2) and 3) above. Cheers. Last edited by Jong; 10th April 2008 at 00:04. |

Look again, i added more...
btw, galapagos hd dvd is weird. When i mux it to mkv the framerate is set (correct) to 29,97fps but both wmr9 & haali renderers try to playback it at 59,97fps, which results in too fast playback and dropped frames. Evr on the other hand deals correctly with it. Wtf? In adition, ffdshow can't decode the video, but that's because it's interlaced and it's a limitation of the libav codec.

Its interesting you posted that particular disc; I recently got the BluRay version of that disc and am having the devil of a time playing it back without stuttering or dropped frames, etc. It is also 1080i / 29.97 fps. It plays back just fine as a BD disc using PowerDVD Ultra, but any other form, I just can't get smooth playback. I've muxed it into an mkv, m2ts, ts, etc. This probably isn't the best thread to discuss that though |

You'll never get Galapagos running perfectly smooth:

Yeah. 1080i has to be deinterlaced for playback, and the "best" way to do that is to bob-deinterlace it - in other words separate the interlaced fields, interpolate them to full height, and output double frame rate (since 29.97i has 59.94 images per second due to the interlacing).
Doing this in real-time can be challenging for a decoder! You may get dropped frames / stuttering etc... Technically, the renderer handles all this stuff. EVR likely offloads it to your graphics card, since it can do a nice job. Haali Renderer _should_ also do this, but who knows. PowerDVD has its own system, which talks to EVR / VMR9. I assume, anyway It's also important that the audio doesn't get played at 59.94! Also, Quote:

Is there a way to demux an audio stream without demuxing video and subtitles as well? Perhaps if I simply output in the same format the audio stream is encoded in, ie, by outputing ac3 track as output.ac3?

Yes, just use something like.
eac3to f:\ n) m: "d:\Moviepath\audiostream.ac3" {–libav} where "f:\" is the path to your drive/virtual drive n) is the title and m: is the stream in that title you wish to convert and "Moviepath" is the working directory you wish to use. Add the -libav switch (without the curly brackets) if you do not have the Nero 7 decoder. Maybe take a look at my new guide to HD-DVD conversion: http://forum.slysoft.com/showthread.php?t=15543 Last edited by Jong; 10th April 2008 at 08:36. |

(1) Either the audio sync issues are so small that they are there but not really noticable. (2) Or the problem doesn't occur because when joining the m2ts parts the timestamps are still in the container which tell the splitter how to keep audio and video in sync. If it's (2) then I expect that you might see some (small) video stuttering at the join points. Maybe just a video frame shown twice or video speeding up a little for a few frames or something like that. What happens if you demux audio and video and then join the demuxed files and mux them to MKV? Are there audio sync problems then? If so, it's (2) from above. If not, it's (1) from above. |

Because it's just the raw audio data without *any* information about the format of the data. So the media player doesn't know how to handle the file. The media player doesn't know how many channels are in the LPCM data or what bitdepth the data has. Information about this is stored outside of the LPCM data in the m2ts container. Quote:

Also I just checked: ffdshow seems to only output 16bit. This is a limitation of the libav decoder. libav audio processing is generally limited to 16bit (unless it is hacked to support higher bitdepths). madFlac always outputs the native bitdepth of the FLAC file. Quote:

The latest eac3to version always copies the log file to the destination folder. |

A good example of this happening is in Ocean's Thirteen. One of the gang are in a Mexican town and are speaking Spanish. I only cottoned on because someone I was watching it with had seen the DVD and said "err, I think there are supposed to be subtitles here". I think the subtitles for this movie won't start until around the 37 minute mark. Hope this helps! |

Maybe the same happens to The Shining hd dvd. That's why the sort sample i uploaded in the previous page doesn't include any subs. I'll look into it.
EDIT: Yep... Subs on this evo start after 300MB. Much after 300MB. As i wrote initially, 1st.evo from that movie don't list any subs, while 2nd.evo does, as well as 1st.evo+2nd.evo combination. EVOdemux shows exactly the same behavior with the 2 evo files. Last edited by nautilus7; 10th April 2008 at 12:20. |

Okay I am making some headway on the lpcm from hd-dvd. Okay now how do the channel mapping work. I have made a .wav file and when I open it sonic scenerist detects it as a lpcm file but complains the channel mapping is wrong. I assume When I make the beowulf.eac3 file I need to add the -0,1,2,3,4,5 at the end.
Sonic expects it to be l c r ls rs lfe so if anyone can help with the channel mapping I think where is used the -blu-ray switch on it before it switched the order to l, r, c, sl, sr, lfe 0 1 2 3 4 5 so if my thinking is correct I need to change the order to -0 2 1 3 4 5 |

eac3to v2.39 command line: "C:\Documents and Settings\er\Desktop\HD Tools\eac3to239\eac3to.exe" "C:\Documents and Settings\er\Desktop\test\test.pcm" ".wavs" ------------------------------------------------------------------------------ This might be a RAW/PCM file. Trying to figure out the details. This will probably take a while. Please be patient... The RAW/PCM file seems to be big endian. The RAW/PCM file seems to have a bitdepth of 16 bits. The RAW/PCM file seems to have 6 channels. RAW/PCM, 5.1 channels, 0:01:19, 16 bits, 48khz This is probably a Blu-ray PCM track. Will remap channels accordingly. Reading RAW/PCM... Swapping endian... Remapping channels... Writing WAVs... Creating file ".R.wav"... Creating file ".L.wav"... Creating file ".C.wav"... Creating file ".SL.wav"... Creating file ".LFE.wav"...

1sec??? Try giving a name to the output files (output.wavs, not just .wavs).
Anyway, demux the pcm and convert it to dts in 1 step using eac3to: Code:
eac3to input.m2ts Code:
eac3to input.m2ts 2: output.dts Last edited by nautilus7; 10th April 2008 at 14:39. |
