And simply set the Max constraint to 8k would lead to vaCreateContext faliure:

Failed to create encode pipeline context: 19 (resolution not supported)

@fulinjie just like we discussed offline, for HW and media kernel, 8K resolution could be handled , but it does not meet the RT requirement , I will change readme , thanks

[fulinjie]

@XinfengZhang Got it, thanks.
