I used to generate fingerprint for an audiofile in Windows 7-64bit and on Ubuntu
but fingerprint codes doesnt same (i mean the code field. ). I used compiled Windows source.
does it supposed to be not same or i did something wrong.
UPDATE
Windows
C:\ecoprint\codegen.exe Kalimba.mp3 > code.txt
Ubuntu
/home/regata/echoprint-codegen$ ./echoprint-codegen Kalimba.mp3 > code.txt
the samples_decoded and code_count fields are different and ofcourse the code part also.
Generated code remain the same. If you ingested full music file and not opted for start and end time while generating code, it should remain the same. If you ingest that code to any other echoprint server, it will matched by the same music files or part of it, atleast 20 seconds of it mostly.

I have a program that extracts text from PDFs. It runs as a scheduled task on Windows Server 2008.
The library I use is ByteScout's PDF Extractor SDK, which is based on Tesseract under the covers.
Since it went live last November, the program has successfully extracted text from over 50,000 PDFs from many different sources.
It recently hung on a single PDF and subsequently on a second one, from the same source in the same visual format.
I am able to recreate the problem using a trivial 12 line program. I sent this program to the vendor but running that program in their environment works (it does not hang).
So I did some experimentation and this is where it gets strange.
The program works on my PC (Windows 7) if I RDP to it, but not if I am directly logged in. This behavior is repeated on other Windows 7 PCs in our environment.
It works on Server 2008 if I am RDPed, but not as a scheduled task.
It works on Windows 10, whether I am RDPed or logged in directly.
If I watch the program in Process Monitor when it is stuck, I can see that it is opening and reading C:\Windows\Fonts\times.ttf over and over again.
If it was only working using RDP, I'd wonder if the cause had anything to do with failing use of graphics acceleration or some such, but given that it doesn't work as a scheduled task where none would be present either, I think that's a blind alley.
Does anyone have any suggestions where to look next?
So ByteScout have fixed the problem. To quote Eugene on the cause ...
The problem is in System.Drawing and GDI+. Sometimes it crashes on text drawing operations that are normal in PDF but causing some internal exceptions in System.Drawing. Moreover, it's behavior varies depending on display device capabilities. That is why it works in RDP session and crashes on a desktop.
We are trying various workarounds on these crashes, attempting to fall back to alternate text drawing ways. The hanging is related to these fallbacks.
I have a compiled program which runs great after being compressed, copied to another computer using a USB key, extracted and ran.
However, if I upload the compressed file to Google Drive or Dropbox, download it and extract it, the program will not run. It gives me an error "program.exe has stopped working".
Using a tool called WinMerge, I compared the program that was extracted from a USB drive with the program that was extracted after being downloaded. Every file, both binary and text, was identical.
Next I used attrib -r -a -s -h on every program file in both folders, thinking perhaps one of the file attributes was incorrect. I still had the same problem; the copied program works, the downloaded one does not.
I also tried changing the name and location of the folders the program was in but it had no effect.
The only thing I can think of is some additional attribute that Windows gives files which were downloaded from the internet, to possibly trigger an additional UAC check which is interfering with the program. Does this exist?
This is on Windows 7.
Found the problem. Windows adds an Alternate Data Stream (ADS) to every file downloaded off the internet. For some reason, these streams were preventing the program from running. Stripping the ADS from each file allows it to run.
I used a Windows Sysinternals program called Streams to strip the ADS data.
Is it possible to output to multiple sound cards under Windows?
It seems that portaudio is the only way to play back through a sound card with Windows, but portaudio offers no mechanism for choosing which device to output to. Even if it did, it isn't clear that it would be possible to open multiple outputs.
Currently, I'm using a hack using VLC to output to the sound cards:
output.external(
%mp3(bitrate=320,stereo_mode="stereo"),
'"C:\\Program Files (x86)\\VideoLAN\\VLC\\vlc.exe" -vvv --config C:\vlc\vlcrc-remote1 -',
remote1
)
output.external(
%mp3(bitrate=320,stereo_mode="stereo"),
'"C:\\Program Files (x86)\\VideoLAN\\VLC\\vlc.exe" -vvv --config C:\vlc\vlcrc-remote2 -',
remote2
)
Each VLC profile has a different sound device set by default. Obviously this could be improved by switching to PCM, but if I can simply skip the whole external process issue completely, that would be great.
This is probably too late now...
Having been searching for this for a all night (several hours) and delving into the source code for PortAudio and Liquidsoap, I have established that LS utilises Pa_OpenDefaultStream() to open one stream only. It is not possible through LS' interface to pass a PA ID to input or output.portaudio. It will always default to device 0 which is the sound mapper (Windows default device).
However, all is not lost, in order to tell PortAudio which input/output to use, you can pass an environment variable before running LS:
set PA_RECOMMENDED_OUTPUT_DEVICE=x
set PA_RECOMMENDED_INPUT_DEVICE=x
Where x is a PA device reference. To find your device references you need a copy of pa_devs.exe (I found a copy here http://www.w1hkj.com/alpha/temp/pa_devs.exe) which when ran generates results.txt. This file contains the IDs you need. You can also get the IDs with Audacity by selecting Help>Audio Device Info.
So you could in theory do multiple outputs like this:
setenv("PA_RECOMMENDED_OUTPUT_DEVICE","13")
streamout1 = output.portaudio()
setenv("PA_RECOMMENDED_OUTPUT_DEVICE","14")
streamout2 = output.portaudio()
I don't know for definite if this will work but it's worth a go! If it doesn't work, you could always run two liquidsoap instances in different settings if this would work for your application.
I wrote a small download script in the C++ part of my QtQuick2 app. This works just perfectly fine when I'm building the app for Mac OS 10.9.
For testing I download this file and when it's done I verify it against the given md5 check sum b3215c06647bc550406a9c8ccc378756
Only when I build the app on a windows PC the verification fails. On the second look I recognise that the size of the downloaded file differ with each downlaod, while the "size on disk" stays every time the same.
Do you have any idea what might trigger the strange behaviour in windows os?
Thanks in advance.
If it helps to solve the problem, I will show you my download script, but it's a pretty simple "read-all-write-to-file" script which runs every two seconds.
Could binary/text writing mode affects the result?
UPD: If you use QFile with QIODevice::Text it may behave differently depending on platform.
When reading, the end-of-line terminators are translated to '\n'. When writing, the end-of-line terminators are translated to the local encoding, for example '\r\n' for Win32.
I am trying to copy C source files from a vms alpha to a windows machine to allow easier editing of the code. (VMS editor is just a text editor and it would be nice to have syntax highlighting etc)
I can copy this across using Exceed FTP and this handles the issue of duplicate filenames with version suffix that vms has:
File.c;1
File.c;2
Flle.c;3
But when I open a file I've transferred, all the line breaks have been lost and the entire file is just one line.
Can anyone recommend a solution to this or offer any hints?
Thanks in advance
ps. I need to be able to copy the files back to vms and still maintain format.
It may be off interest by now, but in case you still wonder about "one-line" text files after FTP transfer.
The short answer: force the FTP transfer mode to ASCII (or text) in your FTP client. This will make sure that the C-files you transferring (in fac all files) are treated as text, otherwise they're assumed to be binary, so you get a byte-stream.
Long answer: There're 2 FTP transfer modes: ASCII/text and binary/image. The default is sometimes clent or server-specific.
Many clients have Auto-mode that interprets the file extension to set the proper transfer mode (.TXT,.CSV etc..)
When you access the VMS server via FTP client, too often the [Win-based] client is not VMS friendy, so it does not parse the file-list properly. Thus it gets confused by version number appended to the "usual" file-name:
filename.ext;ver ==> file.c;1
So instead of seeing .C (and assuming text), it sees .C;1 and thinks it's binary.
I use Filezilla FTP client to/from VMS and so far it does it properly (though version-support is not as I'd sometimes like).
Copying a file to and from your windows desktop every time you want to edit gets old very quickly.
You may be able to implement a much nicer alternative. There is some software under VMS that permits a VMS directory tree to be treated as a "network disk" under windows. Once you've set it up, and set up your windows to recognize the network disk, you can just open the file with a windows text editor without moving it from VMS to windows. You can also browse the directory tree, which appears like a tree of folders.
When you issue a save from your text editor, the saved copy supercedes the previous version over in VMS land. And it mediates correctly between RMS format and embedded newline format. It's a whole lot more convenient than FTP, for this purpose.
After doing a quick Google search, I think the name of the VMS software is PATHWORKS. But I'm not sure.
A few points I have on this
PATHWORKS is fairly old and (as far as I recall - I dont use it) doesnt work well with recent windows versions, such as supporting Active Directory. Within the last few years HP have ported SAMBA to VMS and this is the way to go if you want to make areas of disk visible to windows machines. Should be easyt to find on HP web site.
If you want to try the FTP/SFTP route I would try SFTP and go for VMS version of at least 8.2. TheTCPIP suite was rewritten (or reported from a Unix version) at this point.
VMS supports a number of formats for text files. As well as the complex record structure described above, there is STREAM_LF which is the same as a unix file and STREAM_CRLF
I found some interesting information about OpenVMS text file structure. That corresponds with a vague memory I have of how VMS handles text files; they're not stored as streams of bytes like Windows and Unix systems, but as a sequence of records (each record is a text line). Records can be either fixed width or variable width. Whatever reads the file is responsible for the "paper control", what we normally call newlines these days.
You might check the options in Exceed FTP to make sure that you're transferring the file in an appropriate ASCII mode. There might be special options you need to set on the FTP server to read and write the files in the appropriate mode too.
I'm no expert - let's get that out and in the open ;)
I have been having similar problems in FTPing files from OVMS Alphaserver to Win7 desktop so I can migrate to SQL.
FTP [Attachmate & WIn CLI] workled fine under WinNT.
I suspect Win7 does not like the name.ext;version format of the OVMS file.
Filezilla - doesn't work.
PuTTY - doesn't work
Window CLI FTP - doesn't work [partial file transfer; times out & truncates file].
Using Attachmate's "Reflections for the Web 2011" to emulate Vax terminal - works fine.
Think I'll have to go back to Attachmate for assistance but partially hamstrung by our [Australian Fed Govt] IT services which has the final say
Some editors, such as BBEdit on the Mac, support directly opening/saving files via FTP/SFTP/etc. (BBEdit also supports various different line endings as used on different platforms, which would help with your other problem). I expect there must be a Windows editor with similar functionality - my Windows-using colleagues all rave about something called CodeWrite (or CodeWright ?) so I guess I would take a look at something like that.
