Convert yuv video to png images losslessly
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.
