Hi all,

I'm facing the following bug:
I use kdenlive to edit some clips from a panasonic HDC-SD66 camcorder (MTS, 
AVCHD, 1920x1...@50i ). Those clips are encoded top field first (using mpeg2 
terminology), and this is well detected looking at kdenlive's xml.
<property name="meta.media.top_field_first">1</property>

I understand from various posts that mlt encodes BFF. No matter.
And indeed the rendered file (unscaled interlaced) is BFF.
The problem is that all decoders i have tried (ffmpeg, xine_vdpau_h264, Philips 
TV (no debug there but visible on screen) report the same : the stream is  
flaged TFF. You can imagine the result on medium and fast motion with advanced 
deinterlacers. If i force the deinterlacer to consider the stream BFF, it 
plays as expected.

So, the question :
Who is responsible for this bug ?
MLT ? lavf ? libx264 ?

(mlt, ffmpeg and libx264 up to date).
