delaycut - ac3/eac3/dts/mpa/wav delay+cut tool: v1.4.3.7

[Selur]

delaycut -fixcrc fix -inputtype milliseconds -startdelay -1190 -o "D:\Encoding Output\fixDelay_ger_aid_6122__13_26_48_111_06.ac3" -i "D:\Encoding Output\fixDelay DELAY -1190ms_ger_aid_6122__13_26_48_111_05.ac3"
triggers an unwanted 'milliseconds' Popup-Window, would be nice if this would NOT happen when called through the command line (better output something to std::cerr or std::out)

+ delayac3.cpp misses:
#include "math.h"

+ some thing it wrong with delaycut.pro, using:
QT += core gui
CONFIG += qt \
console

TARGET = delaycut

!win32 {
target.path = /usr/bin
INSTALLS += target
}

TEMPLATE = app

SOURCES += main.cpp\
delaycut.cpp \

FORMS += \

RESOURCES += \

RC_FILE = delaycut.rc
works fine on Linux&Mac

sorry, but how to compile delaycut in ubuntu ?
i check the README but i cant see the instruction
i use

git clone git://github.com/athomasm/delaycut.git
cd delaycut
qmake
make

and it's returned error


g++ -m64 -Wl,-O1 -o delaycut -L/usr/lib/x86_64-linux-gnu -lQtGui -lQtCore -lpthread
/usr/lib/gcc/x86_64-linux-gnu/4.6/../../../x86_64-linux-gnu/crt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
collect2: ld returned 1 exit status
make: *** [delaycut] Error 1

[Selur]

Did you try the changes I posted above? (adjusting delaycut3.cpp and delaycut.pro)
Compiling works fine for me with these changes (on ubuntu 32/64 and mac osx x)

[Snakekick]

@Selur
sorry for my question but how do i make this changes?
i did not have the file delaycut3.cpp
qmake give not response and make give me the same error @hlmasterchief93

**Edit***

delaycut3.cpp== delayac3.cpp

[Selur]

i did not have the file delaycut3.cpp and delaycut.pro
That is strange since, qmake generates the MakeFiles by looking into the delaycut.pro file and they are both listed over at: https://github.com/athomasm/delaycut
I see I made a typo delaycut3.cpp should be delayac3.cpp ;)

Hi guys, I want remove a segment of ac3 file. I put a example:

First part: 0ms-5000ms
Secong part: 6000ms-end

Of this way, I would remove 999ms intermediate. ¿How I should configure delaycut for it?

MKVtoolnix has a function (newly implemented) to trim given specific time lengths.
Which is perfect for trimming the beginning and/or the end of a compliant Matroska file.
Mux the AC3 into an MKA (Matroska Audio) using mmg (http://www.videohelp.com/tools/mkvtoolnix) and apply the splits you want.

Documentation on the -split function here.
http://www.bunkus.org/videotools/mkvtoolnix/doc/mkvmerge.html#mkvmerge.description.split

You can later demux the AC3 using MKVtoolnix (http://www.videohelp.com/tools/mkvtoolnix) with MKVExtractGUI (http://www.videohelp.com/tools/MKVExtractGUI-2) or other tool.

@Sparktank

The easy way is use, like a say to Overdrive80 in other post, eac3to:

eac3to input.ac3 output.ac3 -edit=0:00:05.000,-1000ms

(remove 992ms without recode)

With DelayCut we can Cut first part 0 to 5000ms, obtain the second part with a -6000ms Delay and after join the 2 parts.

Greetings tebasuna51.

How about inserting silence? Would a + sign work for both cases?
Can multiple edits be performed by a single command line?

Many thanks and best regards.

[tebasuna51]

To insert 1000ms of silence:

eac3to input.ac3 output.ac3 -edit=0:00:05.000,1000ms -silence

(with values less than 1000ms the default for eac3to is loop the previous frames)

[mariner]

Many thanks, tebasuna51.

1. eac3to doesn't like -edit=0:00:00.000,12750ms -silence. Minimum start time accepted is 13s. What could be wrong? It's a 6-channel 448kbps AC3 stream.

2. One command for each edit point?

[tebasuna51]

If you want a initial delay is enough:

eac3to input.ac3 output.ac3 +12750ms

Seems a tsMuxeR problem not related with Delaycut or eac3to.

But you can use Delaycut or eac3to to avoid the problem.
When you add a delay here to a ac3 track, silent phisycal frames are added to the ac3 and you don't need add timeshift in audio/video containers.

If you need a delay >4935ms for a ac3 track in m2ts container, first use:

eac3to track.ac3 new_track.ac3 +4960ms

and you can now add the new_track to tsMuxeR without timeshift.

[mariner]

You're right. Will post reply at tsMuxeR thread.

Once again, many thanks and best regards.

delaycut v1.4.3.7 hangs on "crc errors - silence" mode for some files
it just makes zero progress
fixed file remains at zero kb even after an hour
also delaycut becomes unresponsive and won't respond to abort
(but it will close out with the X at upper rt)

esaxple log :
[Input info]
Bitrate=448
Actual rate=448
Sampling Frec=48000
TotalFrames=193208
Bytesperframe=1792.0000

1.3.0.0 performs quickly on same files, a matter of seconds.

if you need a sample please feel free to pm me.

[GCRaistlin]

Is delaycut still being developed? There's some bugs there, has it any sense to report them here?

[Selur]

no clue, but even if it's not developed any more atm. development might start again, so reporting to the bug tracker always is a good idea.

[GCRaistlin]

Selur, you mean reporting here, or there's a special bugtracker for delaycut?

[Selur]

Best report to the bug tracker on the project home page: https://github.com/athomasm/delaycut/issues

[XMEN3]

Hi, i know that eac3to fixes delay in both dts and dtshd tracks when extracting, is possible implement this frame fix on this software?

[Sparktank]

https://github.com/athomasm/delaycut/issues

I get 404 on that.
Even if I reduce to just athomasm, it's 404.

Where there are a new v1.4.3.8, but seems buggy.

Only loading a test ac3 file we can see differences between DelayCut versions:

= INPUT FILE INFO =================
v1.3.0 CORRECT v1.4.3.7 v1.4.3.8
---------------- ---------------- ------------------
File is ac3 ac3 ac3
Bitrate (kbit/s) 192 192 448 (?)
Act rate (kbit/s) 192.000 192.000 448.000 (?)
File size (bytes) 480000 480000 480000

Num of Frames 625 625 267 (?)
Duration 00:00:20.000 00:00:19.968 (?) 00:00:08.512 (?)

v1.4.3.7 is buggy because do a wrong calculation of target file duration.
Then always than I want a cut output one more frame than needed, if I want 3200 ms (100 frames) output 101 frames (3032 ms).

But v1.4.3.8 detect wrong Bitrate, Channels, LFE, etc. (reported here (https://github.com/darealshinji/delaycut/issues/4))

EDIT:
After some changes here is a build than work better than v1.4.3.7: delaycut_testbuild (https://github.com/darealshinji/delaycut/files/602290/delaycut_testbuild.zip)

[tebasuna51]

New release v1.4.3.9 here https://github.com/darealshinji/delaycut/releases

[manolito]

@tebasuna

Too bad but for v1.4.3.9 there is no qt4 build which means that it won't run under my WinXP...

Question:
In this post:
https://forum.doom9.org/showthread.php?p=1797824#post1797824
there is a link to a beta version which also contains a qt4 build. This build runs fine, so I'd like to know if the bugs from v1.4.3.8 are fixed in this beta version?


Thanks and Cheers

I'm not tested all the options but seems OK for me.
