Hello there,
I am running simple encoder.
There is an parameter cfg.rc_target_bitrate tha initializes to 256.
When,how and where at the code happens this initialization?
Thank you

I think you're looking for:
res = vpx_codec_enc_config_default(interface, &cfg, 0);
This uses an array (enc.cfg_maps) from the interface definition
(vp8_cx_iface.c:CODEC_INTERFACE(vpx_codec_vp8_cx)), specifically
vp8e_usage_cfg_map[].
