Compared to 3.99.2 there only was one minor fix that doesn't effect LameXP.
Quote:
LAME 3.99.3 November 26 2011
Fix for tracker item [ 3441349 ] --tg does not handle genre number when adding unicode tag
(LameXP doesn't pass genres by number)

For all these reasons, if no UTF-8 BOM is found, LameXP will now pop up a small dialog, allowing the user to select the desired Codepage.
Yes, that is a sensible solution. However the chances that a string containing a character of value > 127 parses as UTF-8 but is not UTF-8 is almost as negligible as the chances that something starting with UTF-8 BOM code is not UTF-8, since UTF-8 is a rather inefficient and wasteful encoding. (the first byte of value > 127 - which must at least have a value of 247 IIRC - indicates how many following bytes start with the bit pattern 10 - you'll have a hard time finding a word in any language in any encoding - except UTF-8 of course - that happens to conform to this).
For purely random data you should reach the same confidence as a UTF-16 BOM at about 8 bytes > 127 and the same as UTF-8 BOM at about 12.
But enough side-tracking, I'll shut up now and let you all get back to the topic.

Well, at least on Windows, having an UTF-8 BOM is quite common. For example, the Windows Notepad does add a BOM to UFT-8 files. Winamp does add it to .m3u8 playlists as well.

Last but not least, Notepad++ supports normal "UTF-8" (that is with BOM) and "UTF-8 without BOB" (aka "ANSI as UTF-8").

Deciding whether something will decode as valid UTF-8 or not isn't that trivial tough. Especially as I'm not planning to reinvent the wheel and implement my own UTF-8 decoder. Instead I just select the desired QTextCodec class and let it do its job. Also, as far as I understand, UTF-8 was designed in a way to allow for easy resynchronization after "invalid" or "missing" bytes. So decoding errors at one point don't necessarily mean that the rest can't be valid UTF-8...

m4a extension for audio files

Hello again,

Is there any possibility to have .m4a extensions instead of .mp4 with NeroAAC codec?
It is painfull because iTunes and some other apps treats mp4 as video file, so for example I cannot change cover for it like for m4a.

As a workaround I'm using some files renamer after every encoding with great LameXP.

Thanks for reply. I see now that mp4 is correct extension.
..but still you can make life easier for users of LameXP by adding option of using incorrect m4a extension instead.
After weeks of using file renamer (allways after encoding) it is more and more irritating and painfull to do it manualy again.. and again.. and so on.

@LoRd_MuldeR

how to encode in WavPack? or if their is no option for this can i make this as a request?

and i hope someday that LameXP can accept video inputs too so i do not have to demux the audio from the videos

I just realised (out of necessity I guess), could you add an "exit program when finished" just like the shutdown checkbox?

WavePack output is not supported yet, only input.

Didn't see much use for WavPack output, because FLAC provides very similar compression ratio and has much better support in both, hardware and software players.

It's more like a niche product that you may need to convert from now and then, but most people will/should never want to encode to that format.

(If enough people request WavPack encoding, I will consider adding it. So far, you are the first person though)

Not really in the scope of LameXP. Nonetheless a "video import" wizard could be implemented, similar to the "Cue sheet import" wizard.

At least for some container formats, such as MP4 (via mp4box) and MKV (via mkvextract).

What would be the use-case for this?

I see that when you run a longer encode (with lots of files) you may want to go away (or to bed) and keep the encoding process running.

Then it makes sense to shutdown/hibernate the system, as soon as everything is done - to save power.

But why would you want just the application to exit? What is the benefit? The CPU time and RAM used by LameXP while it's idle is negligible.

Also, if the application will exit on completion, you loose all the log/status information...

I was downloading some stuff I knew it was going to take longer than the LameXP encoding, so I set a shutdown task at a given time. If it's ok LameXP being forced to exit by windows then don't add it.

When Windows is initiating a shutdown, it will send a WM_QUERYENDSESSION message followed by a WM_ENDSESSION message to all running applications.

I would assume that Qt processes these messages and closes the application's window (and thus exit the application) in order to allow the system to shutdown gracefully.

But I have not tested this yet. If it turns out that LameXP is blocking the system from shutting down, I will implement some workaround for this...

Update:

LameXP will not block Windows from shutting down, when the main window is showing or when the processing dialog is showing after all files have been processed.

However the processing dialog did block the shutdown when encoding is still in progress. This would be okay, if Windows didn't kill our encoder processes when the shutdown is initiated

It seems that Windows will rigidly kill all processes that have no own GUI window, so our encoder processes have no chance to react. Thus it makes no sense to keep the LameXP main process running.

For this reason I have hacked in a workaround that will force LameXP to quit as soon as possible, if the system is trying to shut down - even when encoding is not yet completed...

Be aware: Windows will rigorously kill all "console" applications, when the system is preparing to shut down. On Windows XP (and earlier) this also applies to GUI application that have a console attached! This means, if LameXP is running on Windows XP and if it has a console attached (the default with "Beta" builds), then it has no chance to do a final clean-up when the system is shutting down. According to M$, this is "by design" and not a bug! At least Windows 7, and probably also Vista, does not behave like this anymore, so LameXP will always do a proper clean-up on those. Last but not least, all "release" builds of LameXP should not be effected (unless you explicitly run with "--console" option).
