 Whenever I use -pix_fmt yuv420p I get the error:

 "deprecated pixel format used, make sure you did set range correctly"

 When I leave the -pix_fmt option I get:

 "No pixel format specified, yuvj420p for H.264 encoding chosen.
 Use -pix_fmt yuv420p for compatibility with outdated media players."

 Why is this? yuv420p is as far as I know correct.
