Did you enable the X use flag? It is just a guess, but running ldd
on /usr/lib/transcode/filter_subtitler.so on my system shows that it
depends on several X libraries. So, probably omitting X will disable the
subtitler filter.

Hi Oliver,

thank you for your help. USE X was indeed missing. I now have
filter_subtitler.so, but loading it aborts with:

[transcode] warning : loading filter module
/usr/lib/transcode/filter_subtitler.so failed
[transcode] warning : /usr/lib/transcode/filter_subtitler.so: undefined
symbol: FT_Init_FreeType

The missing symbol is in /usr/lib/libfreetype.a, but filter_subtitler is
not linked against it:

USE truetype did not help either.

Any ideas?

transcode 0.6.11 doesn't detect freetype properly. You have two options:

1) Edit the ebuild and change the line

econf ${myconf} CFLAGS="${CFLAGS} -DDCT_YUV_PRECISION=1" || die

to

econf --enable-text ${myconf} CFLAGS="${CFLAGS} -DDCT_YUV_PRECISION=1"
|| die


2) Use transcode 0.6.13 from ~x86 (but only if you don't have k3b
installed which requires an older transcode)

You can install k3b and transcode 0.6.13 together if you use -encode
when emerging k3b. This worked for me, since k3b doesn't transcode DVD
video (you have to create the filesystem yourself beforehand). Since I
was using transcode directly to do that, and I don't use K3b to encode
anything else (such as music or (S)VCD), I didn't miss the uncompiled
functionality in K3b.

Ymmv, but just thought I'd mention.

I tried Option 1 now, and it works - it *would*, if filter_subtitler
could find any fonts:

Panteltje (c) movie composer-0.7 (alias subtitle-filter)

Anybody know why it is looking for fonts in ~/.xste (which doesn't exist) ??

According to the subtitler docs in the transcode package, ~/.xste/fonts
is the default location where it looks for fonts. You might want to
create the dirs and copy arial.ttf there. Or, unpack the transcode
source code and have a look at

transcode-0.6.11/filter/subtitler/README.PPML and
transcode-0.6.11/filter/subtitler/demo.ppml

There is an option described to change the font path.
