Convert yuv video to png images losslessly

cppc · 22nd July 2011, 22:23

Hi all,

I use ffmpeg to convert yuv (420) video to images using this command:

ffmpeg -f rawvideo -s size -i input.yuv -f image2 -vcodec png img%03d.png

It works, but my question is: is this lossless? Thanks

It is in the sense that png only uses lossless compression, but because a YUV->RGB conversion is needed, you probably can't get the exact YUV video back again.
