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. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@cordova.apache.org For additional commands, e-mail: issues-h...@cordova.apache.org
