Hi Sebastian & Alston

Thanks for you advice :)

I think the libav plugin codec is software mode to decode H264 in iOS platform, am i right ?

I want to use HW decoding in iOS platform because of performance in my app solution :(

I would have a test with plugin libav and the plugin "applemedia" should be the HW decoding mode,  

so… i really hope it's useful in the near future :)  

Thanks,

- Jojo
