2190,yuv4mpegpipe does not preserve interlaced settings,ulatekh,,"Summary of the bug:

I first noticed this in ffmpeg 0.10.6 from the Fedora Core 17 yum repos, but I reproduced it with the latest version from git too.

I'm trying to package a raw YUV video file in some sort of container so that kdenlive will accept it.  The video is interlaced (miniDV camcorder source).  But every attempt to package it produces a file that says it's progressive video!

How to reproduce:

""head -1 clip.yuv"" outputs ""YUV4MPEG2 W720 H480 F30000:1001 Ib A10:11 C411"" -- notice the bottom-field-first interlacing.  All the lossless codecs I tried (huffyuv, ffvhuff, ffv1, and even rawvideo) produced progressive output.

""ffmpeg -i clip.yuv -vcodec huffyuv clip.avi"" followed by ""ffmpeg -i clip.avi -vcodec rawvideo -f yuv4mpegpipe - | head -1"" outputs ""YUV4MPEG2 W720 H480 F30000:1001 Ip A10:11 C422 XYSCSS=422""

""ffmpeg -i clip.yuv -vcodec ffvhuff clip.avi"" followed by ""ffmpeg -i clip.avi -vcodec rawvideo -f yuv4mpegpipe - | head -1"" outputs ""YUV4MPEG2 W720 H480 F30000:1001 Ip A10:11 C422 XYSCSS=422""

""ffmpeg -i clip.yuv -vcodec ffv1 clip.avi"" followed by ""ffmpeg -i clip.avi -vcodec rawvideo -f yuv4mpegpipe - | head -1"" outputs ""YUV4MPEG2 W720 H480 F30000:1001 Ip A10:11 C411 XYSCSS=411""

""ffmpeg -i clip.yuv -vcodec rawvideo clip.avi"" followed by ""ffmpeg -i clip.avi -vcodec rawvideo -f yuv4mpegpipe - | head -1"" outputs ""YUV4MPEG2 W720 H480 F30000:1001 Ip A10:11 C411 XYSCSS=411""
