Description

I am trying to convert a video to webp and gif files. This results in the webp file being encoded in rbg8 pixel format. Specifying format in the filtergraph or with -pix_fmt does not work

Sample command:

ffmpeg -y -i in.mp4 -pix_fmt yuv420p -filter_complex "[0:v]fps=12,scale=640:-2,split=2[out1][out2]" -map '[out1]' -t 3 out.webp -map '[out2]' -t 3 out.gif

The application cannot insert more filters into the filterchain than you specify.
