Redesign the way -aspect option is handled. This is done by making ffmpeg read the sample aspect ratio set in the corresponding input stream by default, and overriding it using the value specified by -aspect. If the output display aspect ratio is specified with -aspect, it is set at the end of the filterchain, thus overriding the value set by filters in the filterchain. This implementation is more robust, since does not modify the filterchain description (which was creating potential syntax errors).
