AVC fei encode example with bitrate control or single field mode

[Khizbulin__Ildar]

Do you provide examples with sample_fei and bitrate control?  Or else, can i encode interlace avc with single field mode without fei api?

For example, we need  encode like this:

./sample_fei -tff -single_field_processing -g 50 -encpak -i MediaSDK/tests/content/test_stream_176x96.yuv -o output.h264 -w 176 -h 96

with single_field_processing but also with bitrate control,
