< h3 > LameXP - Frequently Asked Questions (FAQ)< / h3 > < br >
< b > What is LameXP ???< / b > < br >
< br >
LameXP is a graphical user-interface for a number of audio encoders. It was developed to support a huge< br >
number of input formats. File formats are detected reliably using MediaInfo. Compressed audio formats are< br >
decoded to uncompressed Wave files using suitable CLI audio decoders. Furthermore LameXP allows batch< br >
processing of multiple audio files. Multithreading is implemented by processing several audio files< br >
concurrently. All the third-party tools incorporated in LameXP are listed in the "About" dialog. The Nero AAC< br >
encoder cannot be redistribited due to licensing issues; it is availabel as a free download from the public< br >
Nero web-site. Note: LameXP does NOT use/need any "external" audio decoders. It neither requires nor supports< br >
any ACM Codecs or DirectShow/DMO filters! And it will NOT install anything of that kind on your system.< br > < br >

< b > My anti-virus program raises an alarm when I try to download/install/launch LameXP. Why is that?< / b > < br >
2011-02-14 23:37:48 +01:00
< br >
Occasionally your anti-virus program may mistakenly detect "malware" (virus, trojan, worm, etc.) in some of< br >
the files here. This is called a "false-positive" and the files are actually innocent/clean. It's an error in< br >
2011-02-15 01:56:48 +01:00
your specific anti-virus software. In case you encounter such problems, goto < a href = "http://www.virustotal.com/" target = "_blank" > http://www.virustotal.com/< / a > and< br >
check the file with multiple anti-virus engines! Moreover take care with results like "suspicious", "generic"< br >
or "packed". Those are *not* real malware detections, they are just wild speculation.< br >

Apparently anti-virus programs tend to suspect installers/uninstaller created with NSIS. Furthermore some< br >
anti-virus programs blindly suspect all UPX'd (packed) executables of being malware. Obviously this is a< br >

stupid generalization, so please ignore those warnings! Last but not least: Always keep in mind that this is< br >

OpenSource software. If you don't trust the people providing the pre-compiled binaries, download the source< br >
code, search the code for "malicious" functions (good luck ^^) and compile your own binary.< br >

DON'T SUBMIT ANY VIRUS REPORTS, UNLESS YOU HAVE VERIFIED THE INFECTION WITH MULTIPLE ANTI-VIRUS ENGNINES!< br > < br >

< b > Who created LameXP?< / b > < br >
< br >
LameXP was written from the scratch by LoRd_MuldeR < MuldeR2@GMX.de> . However it has to be noted that LameXP< br >
uses a number of thrird-party tools, which have been created by the individual authors. Moreover various< br >
people have contributed LameXP translations. Please see the "About" dialog for details!< br > < br >
< br > < br >
< b > What license is LameXP released under?< / b > < br >

< b > How can I use LameXP as a "portable" application?< / b > < br >
< br >
LameXP always is "portable", in the sense that the application works out of the box: LameXP does NOT require< br >
any additional software, such as codecs, encoders, decoders or runtime libraries, and it will NOT install< br >
anything of that kind on your local computer! All the third-party tools used by LameXP are already built-in.< br >
There currently are two notable exceptions: The Nero AAC encoder and the WMA decoder cannot be redistributed< br >
along with LameXP for legal reasons. Therefore these tools have to be obtained as separate downloads.< br >
< br >
Having said that, LameXP stores its configuration file in the %LOCALAPPDATA% folder on the local computer.< br >
That's because on a modern multi-user operating this is the only "correct" folder to store user-specific< br >
configuration files. Also it's one of the few folders where an application is guaranteed to get write-access,< br >
even when the application was launched by a "normal" (non-admin) user and did not request elevated rights.< br >
Storing the configuration file in the "install" folder is antiquated and highly error-prone.< br >
< br >
Still some users may want to store the configuration file in the same folder as the LameXP execuatble file,< br >
e.g. when launching LameXP directly from their USB stick on different computers. For this purpose LameXP now< br >
offers a "true" portable mode. You can enable that mode simply by renaming the LameXP executable file to< br >
"LameXP-Portable.exe". But be aware: When running LameXP in the "portable" mode, the user(!) must ensure that< br >
write-access is granted to the directory where the LameXP exectable is located.< br > < br >
< br > < br >
< b > The LameXP startup (splash screen) takes very long on my system. What can I do?< / b > < br >
< br >
Starting up LameXP shouldn't take longer than approximately 10 seconds. However it was brought to our< br >
attention that badly optimized anti-virus software can slow down the startup procedure a lot! On our test< br >
system (Windows 7 running on an Intel Core2 Q6600 with 4 GB of RAM) starting up LameXP takes about 3 seconds< br >
without an anti-virus software and about 6 seconds with the "real-time protection" of Micorosft Security< br >
Essentials enabled. With other anti-virus software the startup was delayed up to 20 seconds and more!< br >
< br >
So if you think that LameXP is starting up too slow on your system, you should temporarily(!) disable or< br >
uninstall your current anti-virus program and try again. Usually it should be sufficient to disable only the< br >
"real-time protection", "file system protection" or "guard" feature of your anti-virus software. If it turns< br >
out that the startup is signficanntly(!) faster WITHOUT the anti-virus software, please report the problem to< br >
the developer of the anti-virus software. And, if they don't fix the problem, switch to a better product!< br > < br >
< br > < br >
< b > How can I translate LameXP to my language or improve an existing translation?< / b > < br >

< br > < br >
< b > What are the prerequisites to build LameXP from the sources?< / b > < br >
< br >
LameXP is currently being developed using the following build environment:< br > < ul >
< li > Visual Studio 2008, Service Pack 1
< li > Qt libraries v4.7.1 for Windows (VS 2008)
< li > Microsoft Windows SDK v7.1< / ul >
< br >
Also note the following hints:< br > < ul >
< li > You must launch Visual Studio using "qtvars.bat vsstart" in order to enable the Qt tools
< li > The Microsoft Windows SDK v6.0A should work as well, with a few limitations
< li > In order to make a fully "static" build of LameXP, you need to compile Qt as static libraries
< li > Support for the GNU Toolchain (GCC/MinGW + Make) is planned for a future version< / ul >
