Hello everyone.
No one's in IRC at this time, so I figured I'd send a message. I'm the
Windows packager and tried to build Mixxx trunk (what will become v1.8) for
the first time today and ran into a bunch of issues I need some input on:
:
Building with M4A support (using mp4v2 library):
- #include <unistd.h> is present in mp4-mixxx.cpp line 49, which doesn't
work on Windows, so I surrounded it with:
#ifndef _MSC_VER
#include <unistd.h>
#endif
When building that way, I get:
f:\mixxx\trunk\mixxx\src\m4a/mp4-mixxx.cpp(93) : error C3861: 'strcasecmp':
identifier not found
f:\mixxx\trunk\mixxx\src\m4a/mp4-mixxx.cpp(189) : error C2664:
'NeAACDecInit2' :
cannot convert parameter 4 from 'uint32_t *' to 'unsigned long *'
Types pointed to are unrelated; conversion requires
reinterpret_cast, C-style cast or function-style cast
src\soundsourcem4a.cpp(190) : error C2065: 'u_int16_t' : undeclared
identifier
src\soundsourcem4a.cpp(190) : error C2146: syntax error : missing ';' before
identifier 'bpm'
src\soundsourcem4a.cpp(190) : error C2065: 'bpm' : undeclared identifier
scons: *** [win32_build\soundsourcem4a.obj] Error 2
scons: building terminated because of errors.
The first one happens because I have FAAD 2.7 (I built it myself) but Scons
still does the __M4AHACK__ thing and I don't know how to fix that check.
So I built without M4A support and I get:
ASSERT: "unscaled_samples_needed >= 0" in file
src\engine\enginebufferscalelinear.cpp, line 126
...when I try to play or fast forward a track with latency at 1ms. The
analyzer still runs in the background since the overview waveform shows up
eventually. Anything 2ms or above works fine.
If I build the debug version without M4A support, the same thing happens,
and there's also a LOUD pop when it initializes the sound card regardless of
the sound API.
I heard the ugly beeping when fast-forwarding or rewinding once with latency
around 80ms but it went away on subsequent runs.
Regressions:
- First cue point is not defaulted to the start of the track, resulting in
unexpected cue behavior (since there are no cue points, it just pauses.)
- The overview waveform isn't blanked before when a new track is loaded.
- Dragging & dropping from the library causes Mixxx to hang (though the
currently-playing deck still continues.)
- Something's goofy with the resampling because if I have my sound device
set to 48kHz, the output sounds noisy, almost like a dirty record, or 32kHz
sampled sibilance. 44.1kHz sounds better on the exact same source file.
Sincerely,
