Javqui,
did you make any progress on that application? It looks like the HW
encoding support for the A80 is pretty inconsistent in performance (at
least on the Android version I am actually using on the OptimusBoard).
Could you at least share some details about your setup (FW version, kernel
version, details of the OMX fingerprints and so on). It could help a lot.
Thanks
