With this reduced version of the patch kino works WELL and doesn't generates
noise. :-)

Related to transcode I found the following info regarding the libdv patch. It
supossed to solve dv video encoding issues in yv12 and NTSC audio encoding in
raw DV.

I've tested video encoding and couldn't find any difference with or without
patch. The tests I've done was transcoding from xvid to raw dv using "-V
--dv_yuy2_mode" with libdv with and without the patch.

I'm in a "PAL country" I don't manage NTSC video/audio.

  export/vid_aux.* import/decode_dv.c import/import_dv.c
  import/tcdecode.c src/transcode.*: Digital Video DV fixes/updates.
  transcode is now able to adjust to libdv beeing compiled with option
  "--with-pal-yuv=YV12". This the default behavior for PAL users.
  Without this compiler option for libdv, transcode needs the new
  "--dv_yuy2_mode" runtime option. Both modes YUV (-V) and RGB are fully
  supported for de/encoding. Encoding to DV need a patched version (s.
  below) for libdv since YV12 encoding has a bug. You will notice the
  absence of chroma components. In addition, NTSC audio raw DV encoding
  is also somewhat buggy. Encoding to AVI is fine, since the audio is
  encoded in a separate track, wheras in raw DV the PCM audio is merged
  into the video frame. The "libdv-0.99-transcode-patch" is provided on
  the transcode homepage and fixes the YV12 bug and enables NTSC raw DV
  encoding.  You do not need this patch for decoding. transcode compiles
  fine without this patch, too. By the way, "-x af6" enables YUV only
  decoding with "qdv.dll" and "-x ffmpeg" also has a DV decoder. Both
  import modules however do not handle raw DV streams

  I think that if we have not any better solution, the path that only involves
video is a good solution to get Kino working without causing too much problems
to transcode. In transcode you have workarounds to old those issues (RGB mode)
or encoding to AVI or Quicktime DV.

description: 
Kino 0.6.4 in Mandrake 9.1  and in cooker (at 2003/08/21) generates noise
instead of the real audio or even silence when FX are rendered.

I've found info in Kino's forums related to this problem in mandrake and it
suggest recompiling from sources, what seemed to work for some people.

The problem apear to be in libdv. Mandrake libdv2-0.99-5mdk aplies this patch
http://www.theorie.physik.uni-goettingen.de/~ostreich/transcode/libdv-0.99-transcode-patch.bz2.
I don't know what this patch is for but when it's commented and the rpm rebuild,
kino work without any problem.

I think the problem is easyly reproducible and that makes kino useless because
you can not apply any effect or transition without generating that noise.
