I found that the Android ACodec has two different configurations to decode video data from HW decoder(VPU):
1. Configuring TUNNELED video playback.
2. Configuring CPU controlled video playback.
We try to configure the HW decoder to operate under tunneled mode via ACodec.
The Android code base in our platform is
But, we got an error when we try to get extension index from VPU library:
01-01 19:38:15.442 E/OMXNodeInstance( 159): configureVideoTunnelMode extension is missing!
01-01 19:38:15.442 E/ACodec ( 159): configureVideoTunnelMode failed! (err -2147483648).
01-01 19:38:15.442 E/ACodec ( 159): configureTunneledVideoPlayback(0,0xb283cb08) failed!
1. Do we pass the wrong parameter to the VPU in IMX.6 platform?
2. How could we run the tunneled mode in IMX.6 VPU?
