use copy filter before zscale filter. Anyway using y4m is wrong as it doesnt have frame metadata as primaries,matrix coefficients etc. I added support for overriding input params in zscale. so something like this should work: ffmpeg -i input.y4m zscale=min=709:range=full,format=gbrp out.png If it asserts, add copy: ffmpeg -i input.y4m copy,zscale=min=709:range=full,format=gbrp out.png This assumes input colorspace matrix is 709 and range is full. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
