#6147: wrong resolution in output

 Summary of the bug:
 How to reproduce:
 I'm triyng to use ffserver to restream an h264 video stream with 1280x720
 resolution as mjpeg. All work good but the image I can see connecting to
 ffserver is pixelated. The nominal resolution is 1280x720, but it seems an
 upscale from a smaller resolution. If I try to get the stream h264
 directly from ffmpeg the resolution it's ok, I didn't understand if the
 problem is in input on ffserver or in output of ffmpeg.
 My ffserver.conf file is:
 # Multipart JPEG

 <Stream test.mjpg>
 Feed feed1.ffm
 Format mpjpeg
 VideoFrameRate 1
 VideoSize 1280x720
 #VideoQMin 1
 VideoBitRate 128
 Strict -1

 and I launch the software as following:

 ffserver -d -f /etc/ffserver.conf & ffmpeg -i
 rtsp://user:pwd@xxx.xxx.xxx.xxx:88/videoMain -an

 Do I need to change something also in the <Feed feed1.ffm> part?
