Fix #33586: Encoding to mpeg4 makes first frame(s) blocky

Issue was caused by rc_initial_buffer_occupancy being set for context
Commented this option for now -- it's not used in ffmpeg.c.

Now encoding seems to be working nice for MPEG4 and other codecs as well.

However, if there're some gurus around please check :)
