mediacodec: avoid IllegalStateException on some weird devices

01-17 18:53:34.959 E/VLC/VlcCrashHandler(16725): java.lang.IllegalStateException
01-17 18:53:34.959 E/VLC/VlcCrashHandler(16725): 	at android.media.MediaCodec.releaseOutputBuffer(Native Method)
01-17 18:53:34.959 E/VLC/VlcCrashHandler(16725): 	at dalvik.system.NativeStart.run(Native Method)

Personally I don't notice any performance regression.
