The MediaDecoderStateMachine frees the Decoder during its own shutdown. If the the MediaDecoderStateMachine for an MP3 file gets cleaned up before the MP3 frame parser is finished, the OmxDecoder operates with an invalid Decoder. With this patch, the MediaDecoderStateMachine informs the OmxDecoder to clear the decoder field. The MP3 parser logic detects this case and returns. --HG-- extra : rebase_source : 0a00de3cf7b95ede77408e5d43cccbcd706750cd
