I did a test counting video frames and audio frames in one of my cam files.
Video frames: 1495 (2990 fields) = 59.800 sec | eac3to: 2988 = 59.760 sec Audio frames: 1869 = 59.808 | eac3to: 1868 = 59.776 eac3to reports 28 ms overlapping Concatenating this clip e.g five times results in 14948 fields reported by eac3to (2988*5 = 14940) |

Well, the current eac3to build adds 20ms to the last video PTS for PAL interlaced content when concatenating 2 clips (as I said, will be fixed in the next build). So I'd expect eac3to to report 36ms. Don't know why it ends up with 28ms. How long is that clip you're talking about? Can you upload it for me to check out?

I have figured out how to mux seemlessly branched blu-ray's to mkv using eac3to and how to create truehd, pcm and ac3 audio tracks with eac3to. But what I haven't figured out is how to put them all back together into an mkv. I've tried using both Haali and Mkvtoolnix to put both the video file and audio files into an mkv, but both indicate that the pcm and thd+ac3 audio files are not supported media files. I've been successful using tsmuxer to put the files back together, but the truehd tracks won't play in my PCH A-110 even after remuxing with txremux. So, how do I put all of the files I've created using eac3to into an mkv container?

Downsampling AAC
Hi,
might have been reported already, did not read thru all 358 posts ;-) Downsampling 6ch AAC to 2 ch AAC did not work for me. Created a 6ch ACC instead (= did nothing) CMDLine: eac3to 6ch.aac 2ch.aac -down2 Am I missing something? mike |

Hhhm. I've not seen this message before, using Arcsoft to decode:
Code:
M2TS, 1 video track, 2 audio tracks, 4 subtitle tracks, 2:03:59 1: Chapters, 10 chapters 2: h264/AVC, 1080p24 /1.001 (16:9) 3: AC3, English, 5.1 channels, 640kbps, 48khz 4: DTS Master Audio, English, 7.1 (strange setup) channels, 24 bits, 48khz (core: DTS, 5.1 channels, 24 bits, 1509kbps, 48khz) 5: Subtitle (PGS), Swedish 6: Subtitle (PGS), Danish 7: Subtitle (PGS), Norwegian 8: Subtitle (PGS), Finnish Creating file "f:\sin.txt"...

Just do a search on this thread for the very warning message and you'll find the explanation you're looking for. (And maybe next time you can do that before posting... ) |

I'll try again. EDIT: Got it now; for some reason I didn't have the 'search this thread' option before, but it's there now. Last edited by Skinleech; 27th November 2008 at 19:46. |

Question for madshi or anyone smart like him:
SD DVDs with a mpeg2 video stream that is a combination of progressive and interlaced. I've seen it numerous times when I try to strip the pulldown flag. Just wondering what's going on, is there an acutal frame rate change? I assumed DVDs were all progressive on the source by nature. |

No video on .ts files processed with eac3to
Hoping someone can help.
I've been using the following process to produce .ts files of Blu-Ray rips which I can then play via my TVix M6500 "media streamer". 1. Rip Blu-ray disc to hard disk with AnyDVD HD 2. Use eac3to to extract video to .mkv and the audio to .dts or .ac3 3. Use tsMuxeR GUI to create .ts file container the video and audio streams This process has worked fine for weeks but has now started creating a .ts file which has either no video playback or corrupted video playback. The audio is fine. If I use tsMuxeR to extract the video and audio directly from the Blu-ray hard disk copy then the .ts file works okay. But using this method I'm unable to modify the audio output. My preference is to extract the lossless audio stream to DTS using eac3to and Surcode DTS encoder. If I use MKVmerge to create a .mkv file of the same streams the output is fine, but my TviX box is rubbish with large .mkv files with high bit rates so this isn't an option for me. Also tried using eac3to to extract the video to an elementary stream (.h264) then tsmuxed the streams into a .ts file and all works fine. Looking at the mediainfo details for the .ts files which don't work it looks like something odd is going on. The "duration" of the .ts file is twice what it should be. But the individual .mkv and .dts files both have the correct duration. Think it may be the latest versions of eac3to which are producing odd .mkv files. Would welcome anyones thoughts on this one. |

In real life you can not trust the DVD bitstream encoding. You can not trust MPEG2 broadcasts, either. Both often switch between all the various bitstream encoding formats (60 interlaced fields, 30 frames, 24 frames with pulldown flags). Even if you have a stream with 24 frames and pulldown flags throughout the whole DVD, you still cannot always trust that everything is progressive. It's still possible that the wrong fields were encoded together into frames or that the pulldown flags are plain wrong. Because of this a good DVD player usually ignores all this stuff and simply decodes the stream as 60i and then uses a real video processing chip (e.g. HQV Reon) to figure out which of the fields belong together by analyzing the actual image content of all the fields. So IMHO DVDs should never be treated as being progressive - unless you know for a fact that they are encoded perfectly. Quote:
It seems so. I'm not sure how many different movies are out there with such tracks, but at least one movie is. Unfortunately I'm not in a position to fix this. It's technically too complicated. The only proper solution would be for people who have licensed ArcSoft and who own such a problematic 7.1 Blu-Ray disc to report the problem to ArcSoft and ask them for a DTS-HD decoder fix. |

gillie ,
Haali and TSMuxer do not like VC1mkvs. If your final container will be a TS, i'd advise this way: Demux vc1 and audio with eac3to and remux to ts with TSMuxer. If your final container will be an mkv, i'd advise this way: Demux vc1 and audio with eac3to. Open your vc1 with TSMuxer and remux into a ts container. Convert ts to mkv with Graphstudio: Code:
Haali splitter > Haali matroska muxer (MkvMerge gui doesn't recognize raw vc1; so you have to convert it to mkv. Haali splitter doesn't recognize vc1; so you have to convert it to ts) |
