[Kdenlive-devel] pal dv support

[Mikko Rapeli]

I was about to test latest mlt & kdenlive, but is appears quite a few of
my dv files aren't working anymore. I can repeat this with ffmpeg/ffplay
too while mplayer has no problem with them. Here's an example:

$ apt-cache policy ffmpeg

I've tried ffmpeg from debian-multimedia.org and my self build git
versions with same build dependencies. Even statically build ffmpeg fails
with these files. My build options are:

./configure --enable-static --prefix=/usr --extra-cflags="-Wall -g"
--cc="ccache cc"  --enable-libmp3lame --enable-gpl --enable-libfaad
--enable-libvorbis         --enable-pthreads --enable-libfaac
--enable-libxvid --enable-postproc         --enable-x11grab
--enable-libgsm        --enable-libtheora --enable-libdc1394
--enable-libspeex         --enable-nonfree --disable-stripping
--enable-avfilter --enable-libdirac         --disable-decoder=libdirac
--enable-libschroedinger --disable-encoder=libschroedinger
--enable-avfilter-lavf --enable-libopenjpeg

I tried git bisecting but ended up with a early June 09 version which
also didn't work, so I guess this sounds more like a build dependency
problem. 

Does anyone have clue how to fix dv file support?
