That's a bug, but it has no negative effect.

When muxing raw h264 stream to mkv using eac3to it doesn't appear to include the "muxing mode" information in the container. Verified using mediainfo. I understand this isn't anything important, just thought I'd pass it along.
For example: Raw h264 stream to mkv using mkvmerge: Code:
Video Format : AVC Format/Info : Advanced Video Codec Format profile : High@L4.1 Format settings, CABAC : Yes Format settings, ReFrames : 3 frames Muxing mode : Container profile=Unknown@4.1 Codec ID : V_MPEG4/ISO/AVC Duration : 1mn 59s Bit rate : 3 182 Kbps Nominal bit rate : 3 324 Kbps Width : 1 280 pixels Height : 688 pixels Display aspect ratio : 1.860 Frame rate : 23.976 fps Resolution : 24 bits Colorimetry : 4:2:0 Scan type : Progressive Bits/(Pixel*Frame) : 0.151 Writing library : x264 core 65 r1074M b6bb3d4 Code:

I have an HDDVD with an EAC3 track that has a delay of -1001ms. When I processed it (which was a few months ago, so an older version of eac3to, don't remember which), it said it took care of the delay, yet there is still a delay, just not -1001ms. I have not been able to tell exactly how much, but through trial and error, I have narrowed it down to somewhere around 100ms. Could you please add a feature which always adds the correct delay amount to either the file name and/or the log, regardless of if it was processed or not? Even if eac3to was able to process the file correctly to a 0ms delay, that would still be helpful to see. |

I think I read somewhere that about 16ms is as close as anyone can determine a/v sync, could be even bigger, anyone know what the number is? |

A normal human can see a delay mismatch of maybe 30-50ms if he's really good. Many people only see a mismatch of 100ms or bigger. The best eac3to can do with bitstream audio is half an audio frame, which in the worst case is a raster of 16ms correction for AC3 tracks. All other audio tracks have smaller audio frames than that. So 16ms mismatch is worst case. And as I said, if you ask eac3to to decode/transcode audio, delay can be corrected in 1/48 ms steps. Quote:

I am one of those people who are extremely sensitive to audio delays. Last edited by Nullity; 14th January 2009 at 16:56. |

What's the best way to redo 1088 mkvs I made long time ago with gdsmux? I wanna get rid of that gray line. Demux with mkvextractgui, then mux to mkv with eac3to, or mux to ts with tsmuxer and back to mkv with eac3to? or other?
