Hello, how can I extrct video stream from m2ts? It's of format MPEG-4 AVC. It can't be to matroska, so extract to bare video track. But what extension to give it? I've tried .m4v and .avc but eac3to failed
This is the video track I need to extract: Code:
ID : 4113 (0x1011) Menu ID : 1 (0x1) Format : AVC Format/Info : Advanced Video Codec Format profile : High@L4.1 Format settings, CABAC : Yes Format settings, ReFrames : 2 frames Codec ID : 27 Duration : 1h 34mn Bit rate mode : Variable Width : 1 920 pixels Height : 1 080 pixels Display aspect ratio : 16:9 Frame rate : 23.976 fps Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive gives a freeze on 1% of MKV creation (perhaps encryption or some bug) what else format I can use to extract this track and what output extensions are supported by eac3to? Thank U! |

Run With No Log File?
First, let me just commend the author of this wonderful program for all of the time and effort spent. This program has really simplified my life!
Does anyone know if it's possible to use this program to extract audio/video streams w/o producing a log file in the process? |

How to keep decoded wav that eac3to temporarily produce in dts transcoding 1536k->768k (libav) and after manually encode it in dts? Original audio track is 5.0 only and mixed-up channels and Surcode doesnt support that input (at least i dont know how), and decoded wavs are automatically deleted by eac3to when Surcode fails to encode it. I would rather convert it manually in Surcode.

That raises another questiom. I notice when I extract Dolby THD 7.1 track to wavs, that there is a msg displayed in the dialog box "remapping channels".
Why does it do that and will the resulting wavs be incorrect when I enter them into the DTS encoder ?

The remap is between the internal channel order (different in each format: ac3, dts, ogg, aac, ...) and the WAV order.
Don't worry about the message.

Thanks tebasuna, I was interpreting as remapping their positions and it kind of threw me even though I've seen the msg before and never paid attention to it.
But today, all of a sudden, I had an epithany "huh" ?

Hi all
Just after a quick clarification! With this command: Code:
eac3to -input.dtshd -output.ac3 -down6 -down16 -resampleTo48000 -640 -normalize -libav Just trying to get the best quality AC3 as possible and I believe the AC3 encoder in libav is much more actively and recently updated ... Would it be better to start with an MKV, extract the audio and specify AC3 and "-libav" in the extraction (will this force encoding via libav since MKV can't be decoded via libav)? Like: Code:
eac3to -input.mkv -output.ac3 -down6 -down16 -resampleTo48000 -640 -normalize -libav 7ek Last edited by 7ekno; 1st October 2011 at 07:28. |

Thanks guys,
Was mislead from the Wiki entry: Code:
Convert a DTS track to a AC3 one, using libav encoder: eac3to.exe input.dts output.ac3 -libav As for 16 bit, I was under the impression that was standard for AC3 encoder, love to be corrected if that is indeed wrong 7ek |

So, I was making sure that channel assignments and/or downmixing worked well, and tested eac3to on a bunch of channel checks I had available.
The FFmpeg TrueHD decoder was swapping the side and back surround channels. That was fixed recently: http://git.videolan.org/?p=ffmpeg.gi...diff;h=6daf513 Given that eac3to 3.24 is much older than that fix, it should have been affected by the bug - but to my surprise, it wasn't. I used a TrueHD 7.1 channel check available on demo-world.eu I tested it this way: Code:
eac3to.exe input.mkv 2: output.wavs output.SL.wav -> left side surround output.SR.wav -> right side surround output.BL.wav -> left back surround output.BR.wav -> right back surround So I tested it on a DTS-HD MA 7.1 channel check from the Disney World of Wonder Blu-ray, and got incorrect results: output.SL.wav -> left back surround output.SR.wav -> right back surround output.BL.wav -> left side surround output.BR.wav -> right side surround Code:
eac3to.exe -test eac3to (v3.24) is up to date Nero Audio Decoder (Nero 6 or older) doesn't seem to be installed http://www.nero.com/eng/store-blu-ray.html CAUTION: You need Nero 7. Nero 8 won't work with eac3to. ArcSoft DTS Decoder (1.1.0.0) works fine Sonic Audio Decoder (3.24.0.0) doesn't seem to be installed Haali Matroska Muxer (2011-03-03) is up to date Nero AAC Encoder could not be located http://www.nero.com/eng/nero-aac-codec.html Copy NeroAacEnc.exe to the eac3to or to the Windows folder. Surcode DTS Encoder doesn't seem to be installed http://www.surcode.com MkvToolnix (5.0.0.0, release version) is up to date 1) - the FFmpeg TrueHD decoder is patched in eac3to to fix the channel swap bug, and either: - - a. the Arcsoft DTS decoder is swapping channels - - b. eac3to is remapping channels incorrectly from DTS-HD MA 7.1 sources 2) - the side and back surround channels are swapped internally in eac3to, affecting all 7.1 sources - the FFmpeg and eac3to bugs cancel each other out In the latter case, remapping should always be used when dealing with 7.1 sources, whether downmixing or not: Code:
-0,1,2,3,6,7,4,5 Here are the WAV files output by eac3to: no remapping: http://www.mediafire.com/?3r35vr7gpg3v008 -0,1,2,3,6,7,4,5: http://www.mediafire.com/?68q021d69doy8va Last edited by Rodeo; 4th October 2011 at 02:13. |

3) Your test channel is wrong. Please put a exact link (or upload) to the test channel. Please test this test-channel I created now with DTS HD Encoder Suite, here: ss = Side sr = Back http://www.mediafire.com/?sk7mud5h28ol2m4

this would create a ac3 track from the .thd track though. is it also possible to use the orginal interweaved and demuxed ac3 track as input file for this process, together with the thd track?
