Hi all, I am libstagefright developer from rockchip. I am Chen Hengming mail: [email protected]
The rockchip OMX component output buffer normally is MOD16. That is correct. We do not use the published width/height of a stream.
But due to RK3066's GPU hardware limit, the RK3066 OMX component output buffer is 32 bytes align on width and 16 bytes align on height.
So sorry for inconvenience.
Please set output buffer to MOD32 and test whether it is fixed.
BTW the OMX component use memcpy to transmit picture which is not efficient. In Rockchip libstagefright we use zero copy from decoder to render which introduce some private interface which make it difficult to use libstagefright from native layer.
If you need more infomation about that feel free to contact me.
