Proxy capture level 1.3

Hi,

I try to capture a proxy h264 file using level 1.3 with Intel Media software encoder and the encoder return MFX_WRN_INCOMPATIBLE_VIDEO_PARAM, I don`t understand why.

If I capture a similar file using level 3.1 It works.

I attach the 2 log files generated with tracer.exe, one is the log with level 1.3 and the other one is the log with level 3.1.

Can you help me to dertermine what is wrong with level 1.3?

thanks

Karine
