VCU decoder can not restart.

[mGaosi]

vcu-ctrl-sw:

***** /!\ Error trying to conceal bitstream - ending decoding /!\ *****

dmesg:

[36217.926664] al5d a0120000.al5d: Received chan_uid 8. No corresponding channel
[36217.933852] al5d a0120000.al5d: Mail of uid 8 received related to inexistant user

Then the decoder process will restart in my program. Wait for "ScDetectionComplete" but never set:

#0  0x0000ffffada504d0 in pthread_cond_wait () from /lib/libpthread.so.0
#1  0x0000aaaab7406a2c in Rtos_WaitEvent ()
#2  0x0000aaaab7423a2c in RefillStartCodes ()
#3  0x0000aaaab74245e4 in AL_Default_Decoder_TryDecodeOneUnit ()
#4  0x0000aaaab7427238 in Slave_EntryPoint ()

The decoder restart fail and "AL_Decoder_Destroy" not return.
