Hi, I am using:
ffmpeg -i /dev/video2 -r 4 -vf format=pal8 -pix_fmt pal8 -f image2 s-%04d.png to get 4 8-bit PNG screenshots every second from game capture device (if I am understanding it correctly). For my purposes, I need to reduce size further. So I want to get 4-bit PNGs (or 5-bit is also ok). According to [https://trac.ffmpeg.org/wiki/colorspace] I should use colorspaces or zscale to achieve this. Unfortunately I can't find any information on color depth manipulation at [https://ffmpeg.org/ffmpeg- filters.html#colorspace]. So I look at zscale and there may be something at [https://github.com/sekrit-twc/zimg#depth] but I am unable to understand it (too technical). So, can I get 4-bit PNGs using ffmpeg only? If so how? Or I am doomed with needing to program python/go/node ... Thanks. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
