Dear peers,
I use this command to create 2 streams out of 1 with different gop sizes:
ffmpeg -i $1 -map 0:v:0 -c:v:0 libx264 -x264-params
"keyint=24:keyint_min=24:bframes=1" -map 0:v:0 -c:v:1 libx264
-x264-params "keyint=72:keyint_min=72:bframes=3" $2 -y
but the output video streams have only the latest gop structure.
Nicolas George from the ffmpeg-devel mail list told me that I need to
use a stream specifier to achieve the desired result. Can you please
help me to add the stream specifiers to the script above and achieve
different gop sizes for different streams?
-x264-params :v:0 "keyint=24:keyint_min=24:bframes=1" and
-x264-params:v:1 "keyint=72:keyint_min=72:bframes=3"
Regards,
Gyan
