Android Crash : `WaveformExtractor$startDecode$1$1.onOutputBufferAvailable - codec is released already`

[Tom3652]

I have received a new crash of my android app but it seems different from #376 because it's about onOutputBufferAvailable and the release of the codec.

Maybe you will have more insights :

Fatal Exception: java.lang.IllegalStateException: codec is released already
       at android.media.MediaCodec.getBuffer(MediaCodec.java)
       at android.media.MediaCodec.getOutputBuffer(MediaCodec.java:4655)
       at com.simform.audio_waveforms.WaveformExtractor$startDecode$1$1.onOutputBufferAvailable(WaveformExtractor.kt:123)
       at android.media.MediaCodec$EventHandler.handleCallback(MediaCodec.java:1953)
       at android.media.MediaCodec$EventHandler.handleMessage(MediaCodec.java:1851)
       at android.os.Handler.dispatchMessage(Handler.java:107)

       at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:929)
        

I have no ways to reproduce it unfortunately, it happened to my live users in release mode. Thanks for your help !

This looks like codec was already released but a buffer was queued before release and for some reason now in outputBuffer you're getting this crash.

[ujas-m-simformsolutions]

@Tom3652 I have created a PR which returns early if codec is null. Do let us know if this fixes your issue.

[Tom3652]

Yes sure i will use it in my app, thank you !
