Thanks,
maybe let's get on the same page what we both think is working and what not.
I used this simple script:
ffmpeg -i $1 -map 0:v:0 -c:v:0 libx264 -x264-params 
"keyint=24:bframes=1" -map 0:v:0 -c:v:1 libx264 -x264-params 
"keyint=72:bframes=3" $2 -y
to create 2 streams out of 1 with different gop structure. And ffmpeg as 
it is currently produces both streams with keyint=72 and bframes=3. With 
my patch each stream preserves the x264 params set individually. Which 
script you used, that you could get for the similar scenario two 
different gop sized streams?

Thanks,
Alexander
