So I finally got to get round this one tonight - though the
workaround is probably sub optimal. I did try others, but jack was
in a state from all the crashing where nothing was working, leading
me to falsely think they were all failing and dismiss them.
thanks for the patience :-)
Thanks - it turned out that it wasn't jack "in a state" after all, it
was cpufreq on_demand being randomly useless and leaving my 3.4 GHz
cores @ 800MHz. I should have thought of that, as I knew it's rubbish
sometimes when SIMD/threads are involved.
The problem was that as soon as I made one connection the code
behaved like the output has 2 channels, when it only had one.
you are right, it seems i did not expect the binaural decoder to be
called by less than two channels. i solved it in a slightly different
way. thanks for spotting this! should be fixed now.
Yea, working OK now.
I can get sound, though it's not right as I suppose I need to use
converter to play a wxyz - but converter also crashes, so I'll have
to look at that next.
yes, you have to use the converter to play recordings that use FuMa
channel sequence and weighting. i just checked the converter and
could not find anything suspicious which could cause a crash. maybe
you are lucky again and find the cause?
I haven't attempted my own fix, or looked much yet, but looking at the
backtrace it seems to be a similar issue.
I am now compiling first order (JFTI, though I doubt it makes any
difference).
I can avoid the crash in at least 2 ways -
Connect outputs first.
Have 2D checked on input.
To produce the crash I need to connect the inputs first - the problem
being when connecting the second.
juce::FloatVectorOperations::copy
is #1 in the trace but judging by your previous fix I guess #3
ambix_converter/Source/PluginProcessor.cpp:537
will roughly be the place to change. I see you already had some
debugging there so uncommenting them (lines 503 and 532) I see lots of -
InputCh: 0 IN_CHANNEL: 0 OUT_CHANNEL: 0
NumInputChannels: 1 Buffersize: 1
When 1 input is connected then on connecting the second -
NumInputChannels: 2 Buffersize: 2
InputCh: 0 IN_CHANNEL: 0 OUT_CHANNEL: 0
InputCh: 1 IN_CHANNEL: 2 OUT_CHANNEL: 1
Segmentation fault
I have found a couple of other issues one trivial = the octagonal preset
looks wrong (12 channels).
The second could be more tricky as it doesn't seem to be reliably
reproducable = a crash in zita convolver when changing presets while
playing something.
Anyway thanks for the software and I'll continue testing etc. At least
now I can listen to some music while testing :-)
