Comment:

 The behavior has changed now. I cannot reproduce the assertion anymore but
 using yadif=1 still does not work. It produces a huge amount of error
 messages (over 100mb in some seconds). Maybe this is a new issue. Please
 close again if this should be reported in a separate ticket.

 Example:
 {{{
 $ ffmpeg -i 00001.MTS -vf movie=00001.MTS,yadif=1,setpts=PTS-
 STARTPTS,scale=1280:720[mov],[in]yadif=1,setpts=PTS-
 STARTPTS,[mov]overlay=0:0 -y out.mp4
