[FFmpeg-user] Changing video size mid-stream

Hello all,

I have a program that outputs raw video data to ffmpeg like this:

./gen-vid | ffmpeg -f rawvideo -pixel_format bgra -video_size 1366x713 -framerate 30 -i - -vcodec png overtest.avi

I am wondering if there is any way to change the video size mid-stream 
without skipping any frames? Any ideas? Thanks!
