scheutzo <[email protected]> added the comment: i also see checkerboard artifact with: (1) ffplay -x 504 -y 376 test.tif but this works for me: (2) ffplay test.tif and this works for me: (3) ffplay -vf "scaler:504:376" test.tif
The difference between (1) and (3) is that (1) uses SDL to rescale the image, and (3) uses libswscale to rescale the image. My version of libSDL is 1.2.14, which installed with filename libSDL-1.2.so.0.11.3. Rescaling using -x and -y could be fixed by always scaling to the final display size prior to reaching the overlay buffer. I don't know the history that lead to the current design, which depends on the SDL scaler. ---------- nosy: +scheutzo ________________________________________________ FFmpeg issue tracker <[email protected]> <https://roundup.ffmpeg.org/issue1804> ________________________________________________
