Re: recording sound problem with new mac pro

[Peter Bogdanoff]

I also saw this happen. I believe it is a problem based the version of OS X 
that you are using, and probably the implementation of QuickTime by OS X in 
your new Mac.

1. Apple is scaling back support for QT—I think this is a symptom of that.
2. Currently LiveCode requires QT to enable recording.
3. LiveCode is planning to implement recording using the native AV 
Foundation—but that hasn’t happened yet.

So, in the meantime—apparently you will not be able to record in LC on your Mac 
Pro.

Re: recording sound

[Robert Mann]

Thank you Phil for this smart "turn-around". I so wish audio would be
"straightened up" in livecode! Amazing for a language in the heritage of
hyper talk! 

Additionnaly, I wanted to have a clue :: do other user manage to record any
audio with v7 on later osx than 10.7? Does it work on 10.8.. 9.. 10..11??
And how? formats, quality (40.100 kHz?) Thanks.

Re: recording sound

[Phil Davis]

Robert,

I just re-read your post and realized my solution still couldn't address 
your issue - that of sound quality. Unless... is there an earlier 
version of LC where 44.1 khz stereo was supported? If so, you could 
build a slave app with that.


I suppose you could use a commandline app like ffmpeg to record. I've 
used ffmpeg to crop and convert media files from shell(), but never used 
it to record. Should be a way to make it work - maybe open as a process 
for update? Dunno.

Hi Robert,

I recently had to deal with this as part of moving a Mac-only desktop 
app I maintain for a client from LC 6.x to 7.x. My solution (which 
works nicely) was to create a standalone 'slave' app using LC 6.6.5 
whose only job is to record sounds. This recorder app is stored in the 
bundle of the main 'master' app and is launched in the background when 
the master app's 'audio editor' window is opened; then is told to quit 
when that window closes. While running, it receives its orders from 
the main app via sockets, and sends a response upon completion of 
every command. That way we know if it's alive and working.


It handles only a few commands:
startRecording
stopRecording
terminate
enableLogging -- for testing
disableLogging -- for testing

Of course to simplify things on the 'master app' side I created a 
library containing the commands used by the main app to send 
recognized commands to the slave app.


It's fun to see it work!

I need to record on mac os desktop machine :

exchange these file easily via the net.

The state i'm in is ::

-- livecode 6.5 mac osX 10.7.4 (my last commercial version)
=> can only record 32000 kHz stereo 16 bit wav none compressed
-- nothing else works. And compression requires to use some external 
utility
like lame (but i can't take the risk to oversee lame installation 
problems

on other peoples machines and 2 out 3 friends who tried to install lame
found some issues).

-- LiveCode Community 7.1.2 / mac os x 10.7: record function just 
does not

work, no file is created (same test stack as used with livecode 6.5).

-- LiveCode Community 7.1.3 / mac os x 10.7: record function just 
does not

work, no file is created (same test stack as used with livecode 6.5).

is there somewhere a secret command to open up recording function???

I checked that av foundation is said to be incorporated into os X from
version 7 onwards.
thanks..
