How do I determine which playlist contains the correct movie? I ran eac3to and got the following results: Both indicate they are the same length, but use different m2ts files.
Code:
D:\Video Ripping\eac3to>eac3to i:\dieanotherday 1) 00001.mpls, 2:12:34 [130+131+133+134+136+137+139+140+142+143+145+146+148+149+151+152+154+155+157+ 158+160+161+163+164+166+167+169+170+172+173+175+176+178].m2ts - h264/AVC, 1080p24 /1.001 (16:9) - DTS Master Audio, English, multi-channel, 48khz - AC3, Spanish, stereo, 48khz - AC3, French, multi-channel, 48khz - AC3, English, stereo, 48khz - AC3, English, stereo, 48khz - AC3, English, stereo, 48khz 2) 00099.mpls (angle 2), 2:12:34 [130+132+133+135+136+138+139+141+142+144+145+147+148+150+151+153+154+156+157+ 159+160+162+163+165+166+168+169+171+172+174+175+177+178].m2ts - h264/AVC, 1080p24 /1.001 (16:9) - DTS Master Audio, English, multi-channel, 48khz - AC3, Spanish, stereo, 48khz - AC3, French, multi-channel, 48khz - AC3, English, stereo, 48khz - AC3, English, stereo, 48khz - AC3, English, stereo, 48khz 3) 00200.mpls, 00028.m2ts, 0:51:40 - MPEG2, 480i60 /1.001 (16:9) - AC3, English, stereo, 48khz 4) 00201.mpls, 00029.m2ts, 0:23:35 - MPEG2, 480i60 /1.001 (16:9) - AC3, English, stereo, 48khz 5) 00202.mpls, 00030.m2ts, 0:22:39 - MPEG2, 480i60 /1.001 (16:9) - AC3, English, stereo, 48khz D:\Video Ripping\eac3to> |

This movie seems to have multiple angles. This is usually used to encode different languages in a space saving way. E.g. credits in English, French, German etc. Usually angle 1 is English, but there's no guarantee for that, so you better check out the different m2ts parts yourself to find out which angle is which language (as jj666 already said). |

Example 1, Basic Instinct (Blu-Ray) + DTS-Core - frameSize 2012 - DTS-ES + - channelNo 6 - lfe 1 - channelDescr 6.1 - samplingRate 48000 - bitDepth 24 - bitrate 1536000 - extAudio XCh - samplesPerFrame 512 - copyHistory 1 + DTS-HD - fullSize 2040 - headerSize 28 - refClockCode 1/48000 - frameDurationCode 1 - activeMasks [1], [[1]] + Asset [0] - fullSize 2012 - headerSize 10 - corePackets Core+XCh - extSubStrPackets XBR - bitResolution 24 - maxSampleRate 48000 - totalNumChannels 7 - activeSpeakers C L R Ls Rs LFE Cs ($1f) DTS Hi-Res, 6.1 channels, 0:00:14, 24 bits, 3093kbps, 48khz (core: DTS-ES, 6.1 channels, 0:00:14, 24 bits, 1536kbps, 48khz) Code:
Example 2, Herbert Grönemeyer 12 live (HD DVD) + DTS-Core - frameSize 2012 - DTS-ES + - channelNo 5 - lfe 1 - channelDescr 5.1 - samplingRate 48000 - bitDepth 24 - bitrate 1536000 - samplesPerFrame 512 - copyHistory 1 + DTS-HD - fullSize 1400 - headerSize 28 - refClockCode 1/48000 - frameDurationCode 1 - activeMasks [1], [[1]] + Asset [0] - fullSize 1372 - headerSize 12 - corePackets Core - extSubStrPackets XXCh+X96 - bitResolution 24 - maxSampleRate 96000 - totalNumChannels 8 - activeSpeakers C L R LFE Lsr Rsr Lss Rss ($84b) DTS Hi-Res, 7.1 channels, 0:00:16, 24 bits, 2605kbps, 96khz (core: DTS-ES, 5.1 channels, 0:00:16, 24 bits, 1536kbps, 48khz) Code:
Example 3, House of 1000 Corpses (Blu-Ray) + DTS-Core - frameSize 2012 - DTS-ES + - channelNo 5 - lfe 1 - channelDescr 5.1 - samplingRate 48000 - bitDepth 24 - bitrate 1536000 - samplesPerFrame 512 - copyHistory 1 + DTS-HD - fullSize 1740 - headerSize 32 - refClockCode 1/48000 - frameDurationCode 1 - activeMasks [1], [[1]] + Asset [0] - fullSize 1708 - headerSize 13 - corePackets Core - extSubStrPackets XBR+XXCh - bitResolution 24 - maxSampleRate 48000 - totalNumChannels 8 - activeSpeakers C L R LFE Lsr Rsr Lss Rss ($84b) DTS Hi-Res, 7.1 channels, 0:00:14, 24 bits, 2864kbps, 48khz (core: DTS-ES, 5.1 channels, 0:00:14, 24 bits, 1536kbps, 48khz) Basically, if you want to know what you'll lose by extract the core, you should use the undocumented "-logdts" switch and then check out which extensions are stored in the DTS-HD blocks. If you strip off XCh or XXCh extensions, you're losing additional channels. If you strip off the X96 extension, you're losing 96khz. If you strip off the XBR extension, you're losing additional bitrate for the 5.1 channels. If you strip off the XLL extension, you're losing Master Audio. XCh, XXCh and X96 extensions can be contained in either the core or in the DTS-HD blocks, while XBR and XLL extensions can only be contained in the DTS-HD blocks...

So by looking at this example, is the only information stored in the HD extension is the extra channels (XXCh)?
Thanks for the great explanation BTW. Code:
The Condemned + DTS-Core - frameSize 2012 - DTS-ES - - channelNo 5 - lfe 1 - channelDescr 5.1 - samplingRate 48000 - bitDepth 24 - bitrate 1536000 - samplesPerFrame 512 - copyHistory 1 + DTS-HD - fullSize 716 - headerSize 28 - refClockCode 1/48000 - frameDurationCode 1 - activeMasks [1], [[1]] + Asset [0] - fullSize 688 - headerSize 11 - corePackets Core - extSubStrPackets XXCh - bitResolution 24 - maxSampleRate 48000 - totalNumChannels 8 - activeSpeakers C L R Ls Rs LFE Lw Rw ($40f) DTS Hi-Res, 7.1 channels, 1:53:39, 24 bits, 2083kbps, 48khz |

We know the FrameLength (must be constant) and the FileLength then can have: Frames = int(FileLength/FrameLength) Each frame have 1536 samples, at 48000 Hz each frame have 32 ms then: Duration = frames x 32 ms.

Yes, corrected it.
It's not so bad. Look, if this wasn't a DTS-HD track, both the 5.1 channels and also the XXCh extension would be in the core. In that case the XXCh extension would eat away bitrate from the 5.1 channels. In other words: The 5.1 channels wouldn't have full 1536Kbps. Instead you would maybe have 1200Kbps or something like that for 5.1 and the rest for the additional channels. But thanks to DTS-HD the XXCh extension could be moved to the DTS-HD block, so the full bitrate of the core could be spent on 5.1. So you should have a really good sounding 5.1 core. |

Yes, exactly that. In fact, SSRC includes this option (in 2-pass mode, of course) so maybe you could use existing code.

Like NotFixedDelay is 0, the first header begin at first byte then a correct ac3 stream must have all frames ok, until the last truncated by a buggy video editor. Quote:

nvm then, deleted these entries
but wheres that goddamn delaycut thread to be found? search engine is bs in that case and searching with strg+f for "delay" also didnt lead me there 20 pages in the audio section. so at least dont be surprised questions are asked here. heres another sample similar to that of robocop, another h264 1080i50 movie. I also have sync problems when slowing down that one, tried it with and without the gaps file. the runtime of the original video is 1:26:58, so the slowed down version should be about 90,7 minutes. with gaps file usage the length is ~1:30:05 (or similar), without gaps file 1:30:36, which also is a little off. http://www.sendspace.com/file/fyonek Last edited by Thunderbolt8; 15th November 2008 at 14:05. |
