When I do use "-O infer=PERSERVE_Y" I get small black bars left and right. Actually, this is strange since the photo's from my digital camera have a 4:3 ratio and PAL also has a 4:3 ratio, so I what expect it to fill the full video frame without any clipping or black bars. > but when I use "-O infer=PERSERVE_Y" or "-O infer=PAD" than the script > produces "memoryaccesserror 4952" for every conversion, how can I avoid this > and can I get padded MPEG-immages with black bars for the space not used? > >
Tried both options and they seem to work fine here, I do not get a "memoryacesserror". If I use y4mscaler without these options it will also add black bars if needed, just tried it with a photo in portrait format and it gives me black bars left and right: djpeg IMG_5171.JPG | ppmtoy4m -r -n 200 -F 25:1 | y4mscaler -I sar=1:1 -O preset=DVD | mpeg2enc -f 8 -o photo3.m2v But, it also adds small black bars on the bottom and top, to remove these I needed to specify "-O infer=PRESERVE_Y -O infer=EXACT".
