Hey, got an idea for you. Try

ffmpeg  -loop_input -i 800x600.jpg -an -s 1288x360 -vf
[in][wm] overlay=2:4[in+wm];
[in+wm][wm2] overlay=646:4 [out]'
-s 1288x360 -vcodec rawvideo /home/fifo/mpegpipe99.yuv

This should skip first second of video from first source. Amount of
time can be adjusted (second operand in gte( ).
I can't test it, so i'm looking forward for your results.
