Extinguished some remaining uses of argv[] or QApplication::arguments().
2012-06-23 18:18:57 +02:00
30bc239cd8
Now using our own command-line parser, based on GetCommandLineW() + CommandLineToArgvW , instead of using QApplication::arguments(). This is less portable, but Qt's internal command-line parser has some rather strange behavior with processing certain characters. As a result, with Qt's command-line parser, some path names passed to LameXP got screwed up! Specifically "C:\Some Path\''Foo''.mp3" got mangled to "C:\Some Path''Foo''.mp3", i.e. the Backslash disappeared! Should be fixed now.

When generating the initial output-folder name for the Cue Sheet dialog, make sure there is no folder *or* file of that name yet. The previous code did check for folders only!

Now using a separate QSemaphore to limit the number of tasks in the queue of the QThreadPool. Instead of starting exactly as many task as there are threads in the pool and adding a new task only after a running one finished, we will now keep a fixed number of tasks in the queue (currently hardcoded to 32). Since there always will be more tasks left in the queue than there are threads in the pool, we ensure that no thread will ever become idle. Might be slightly faster than the "old" approach.
2012-05-25 02:24:44 +02:00

Fixed HTML code, need to escape the ampersand.

Changed the method to synchronize the analyzer threads: We now use QSet to maintain a list of the thread id's of all threads that are still running - instead of only recording the highest thread id that has finished. This way a thread can now actually check if there still is any running thread with a lower thread id. Before thread n could only check if thread n-1 has finished yet or not. As a result we can relax the waiting now. Only threads that want to emit a file will wait for the "previous" threads to finish.

6cfcf067cc
Implemented multi-threading for tool extraction. The extraction of the tools is limited by a/v software. Without an a/v software interfering, the extraction takes no time (less than a second on the test machine). With an a/v software slowing down things, it can take up to 20 seconds or longer. By extracting several files in parallel, we give the a/v software the chance to take advantage of multi-threading. Should help quite a bit, on multi-core systems.

New workaround to focus the selected item in the "output folder" view: As the focus will get lost again when the QFileSystemModel asynchronously loads a directory, we need to focus again on each directory loaded. Though we must stop focusing on the selected item, as soon as the user expands a folder. Otherwise the view would scroll unexpectedly...

Workaround for Windows XP: It appears that QThread::isRunning() may return TRUE even after the QThread object has already emitted the "finished" signal. For some reason this only occurs on Windows XP, but never occurs on my Windows 7 machine. As a workaround we will call QThread::yieldCurrentThread() and then try again. This seems to fix the issue on my Windows XP machine.

More FLAC workarounds. Using "--channel-map=none" will fix most cases, although we will loose the channel map for Wave files that contain a valid channel map. On the other hand, FLAC fails most of the time when trying to use the channel map from the Wave file.

Some workarounds for FLAC. It seems FLAC doesn't like 1.0, 3.0, 3.1, 4.0 channel files. It also doesn't like more than 6 channels. It still fails with files that have >2 channels and are NOT in the "Wave Extensible" format.
2012-03-09 00:44:55 +01:00

Fixed detection of 32-Bit Float data via SoX. For whatever reason SoX returns a "precision" of "24-Bit" for 32-Bit Float Wave files, so we have to detect the actual precision from the "sample encoding".

a450862150
Patched Qt's QProcess class to pass the CREATE_BREAKAWAY_FROM_JOB flag when creating a new process. This is required, because Windows (Vista and later) will add our child processes to the PCA (Program Compatibility Assistant) job object automatically! And then we cannot add the child processes to our own job object, as a process can be assigned to only one job object. With the CREATE_BREAKAWAY_FROM_JOB flag, we ensure that our child processes does NOT get added to the PCA job object automatically and we can add it to our own job object again. Unfortunately QProcess does NOT provide a way to pass process creation flags yet, so we have to patch Qt for now. Passing the CREATE_BREAKAWAY_FROM_JOB flag may not always be desired though...
2012-03-01 23:14:41 +01:00
2ee08c5f4b
Fixed a regression in d92fb7fbcc: We must not close the handle to the Job Object, as long as there still might be a process "tool" running. The regression caused child processes to be terminated unexpectedly sometimes! We now use reference counting in order to avoid this problem.

Fixed a potential live-lock situation: Signals from the QThread can get lost, before we reach the QEventLoop->exec(), even if the required connections already exists. It seems that QApplication::processEvents() will discard signals for our QEventLoop, if that QEventLoop is not running yet! Without the QApplication::processEvents(), those signals would simply be enqueued until we call QEventLoop->exec(). In reality this bug was never triggered under normal circumstances, but it seems on some systems it can take longer to perform the "fade in" than to finish the initialization thread. In that situation the bug *was* triggered and caused the live-lock...

Better handling of system shutdown. Now using the Qt event system to broadcast a special event when the system is going to shutdown (i.e. WM_QUERYENDSESSION or WM_ENDSESSION). This gives each top-level widget the chance to react to the system shutdown *before* we return from the message handler. Doing any clean-up after returning from the message handler is impossible, because Windows will kill the process immediately after WM_ENDSESSION has been processed. Note that Windows XP (and earlier) will NOT send WM_QUERYENDSESSION or WM_ENDSESSION to processes that have a console attached! Therefore, if we have a debug console attached, we cannot do anything on these systems. Our process will be killed without any notification...
...
Also improved LameXP's IPC mechanism: There now are several slots for IPC-commands in the shared memory area ("queue support"). This way, the sender can post several commands in sequence without getting blocked. The receiver can process those at a later time.

Windows will kill our process immediately after we return from handling the WM_ENDSESSION message, so we have to clean-up explicitly *before* returning from the message handler. Not nice, but there is no other way. Also, as Windows will kill our process anyway and thus prevent a proper application shutdown, we can just call exit() from the message handler. This makes sure nothing "unexpected" can happen in the short moment that our application would continue to run after returning from the message handler.

Explicitly handle WM_QUERYENDSESSION and WM_ENDSESSION messages to make sure LameXP won't block Windows from shutting down.

Restrict bitrate selector for dcaenc to a sane range. It seems everything above 4096 kbps will fail, even with 6 channels.

Updated dcaenc. Also encoders can now report all supported channel numbers and downmix will be invoked as needed. We still downmix to Stereo, if the given channel number isn't supported. In a future version we should downmix to the most suitable supported channel number.

Update file properties after the decoding step by using SoX in "--i" mode. Required, because some properties (such as 'bits per sample') cannot be known beforehand.
