Hi All,

There are parameters given in avcodec.h file for video encoding. i have some
doubts regarding some of the parameters given as below:

1. i_quant_offset is used to set qscale offset between P and I-frame. Please
share what is the meaning of qscale offset?
2. how rc_max_rate parameter is different from bit_rate parameter?
3. what is the use of rate_emu, rc_buffer_size, mb_qmin, mb_max,
frame_skip_threshold, frame_skip_exp, frame_skip_cmp parameters?

I need to know how these parameters help in encoding. If there is document
that helps to understand these terms then please share.
Any help would be highly aprreciated.

Thanks in Advance
