mpeg4 encoding to youtube 480p resolution fails

GoogleCodeExporter commented 8 years ago

Command line and output:

Error while opening encoder for output stream #0.0 - maybe incorrect parameters 
such as bit_rate, rate, width or height

ffmpeg seems to adjust the pixel aspect ratio with a warning and performs the 
same transcoding.

854:480 ist the resolution recommended by youtube encoding guidelines for 480p. 
Is there a command line workaround for this?
