CB-12542: (ios) Fix wav file recording, add m4a extension. make IOS status
handling compatible with Android/Windows
implement a "messageChannel" command and if the messageChannel
command is called the plugin hands back results to the plugin
container via "sendPluginResult" instead of "evalJs"
even for oldschool usage it cleans the code
Closes #134.
> can’t record to a “wav” file on IOS media plugin
> ------------------------------------------------
>
> Key: CB-12542
> URL: https://issues.apache.org/jira/browse/CB-12542
> Project: Apache Cordova
> Issue Type: Bug
> Components: Plugin Media
> Affects Versions: 3.5.0
> Environment: 9.x Simulator , IOS 8.x device (iPod touch)
> Reporter: Leo Schubert
> Assignee: Filip Maj
> Priority: Critical
> Labels: pluginsrelease

> I get “Failed to initialize AVAudioRecorder: (null)” in the error callback of
> the startRecordingAudio() exec API.
> I see that the AVAudioPlayer settings in CDVAudio.m are
> {code}
> NSDictionary *audioSettings = @{AVFormatIDKey: @(kAudioFormatMPEG4AAC),
> AVSampleRateKey: @(44100),
> AVNumberOfChannelsKey: @(1),
> AVEncoderAudioQualityKey:
> @(AVAudioQualityMedium)
> };
> {code}
> This is IMHO the reason it doesn’t work. Either one uses the .m4a extension
> with {{kAudioFormatMPEG4AAC}} or
> .wav with the {{kAudioFormatLinearPCM}} key (the IOS docs are very unclear
> about which file extensions are actually supported)
> The plugin enforces “wav” but the settings enforce the MPEG4AAC encoder.
> Using the attached simple patch and using .m4a at the JS side solves the
> problem and records on my iPod touch IOS 8.x.
> I stumbled also across
> https://github.com/remoorejr/cordova-plugin-media-with-compression where the
> exchange wav->m4a is done too.
> Strangely I can’t find much problems reported on stackoverflow, but this one
> seems to cover it
> http://stackoverflow.com/questions/12244111/failed-to-initialize-avaudiorecorder-null
> The last poster seem to indicate that the problem sneaked in in IOS 8
> (previously it was probably possible to record to a .wav file but with AAC
> content).
> Looking at the recordAudio() test for the plugin in tests/tests.js I can’t
> see that potential errors are actually causing the test to fail: they are
> just logged with console.log , so this may explain why the problem has not
> been detected by the tests.
