Re: [FFmpeg-devel] [PATCH] allows for independent codec setting per output video stream
I checked it works before replying. 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?

Hi Nicolas, I guess it is supposed to work in this way but it doesn't. And if you look in the code you will see, than only one codec_opt is served for all c:v:0, c:v:1 etc. Best regards, Alexander /// On Mon, Apr 26, 2021 at 7:54 PM Nicolas George wrote: > Alexander Solonsky (12021-04-26): > > Sometimes it is useful that output video streams have different gop > > structure and other settings.

You need to use a stream specifier. For further questions, please ask on the users mailing-lists.
