[Cemal Direk]

Hi, im using this code

"ffmpeg -i video.mp4 -filter:v "fade=t=in:color=white:st=0.5:d=1" -filter:a
"afade=in:st=0:d=1, afade=out:st=44:d=1" -c:v libx264 -c:a aac output.mp4"

then output is wrong codec. i can not open output.mp4 at any player.
but i dont give to color=white parameter to command i can open output.mp4...
whats the problem when i adding color parameter to command?(:color=white)
