fix ticket #11531
the rtsp aac did not marked keyframe which cannot easy copy to output.
because f265f9c9d04863180503707bfad285f48e6bf080 commit change the AAC props to match xHE-AAC.
in some formats like MOV, need_parsing is set, so AAC can be still parsed be keyframe
but rtsp did not, so this patch add it
