Hello to all. I've made some modifications on drawtext filter which I
currently use at work.
The modifications are the support of controlling the spacing between
lines and a very primitive support for borders around text. It's
primitive because it works only with one or 2px (I basically copied
ops, wrong mailing list :-(

Ooops, The error was mine, not of libavfilter. I was encoding a frame
without filtering (a noob's problem of variable name) when I had to
use the frame resulted of filer process.

Hello to all. I'm trying to use libavfilter and initially I created a
simple .c file which reads a frame from a input and convert this frame
to an output png image.
I tried to follow the file doc/examples/filtering_video.c and right
now my program just open a file, get a frame and save it in a
I had read the parser but I couldn't find the flags option. Now you
said I can see it in libavutil/opt.c:195.
Thx a lot :-) I will report the documentation issue.

Hello to all. I'm using the drawtext filter in a project and I
couldn't use the ft_load_flags option. I'm using ffmpeg 0.11, but I
also tested in 0.9.2 and from master branch. The results are the same.
What I have to to is write the text using the FT_LOAD_MONOCHROME
(defned in freetype.h), which
I think I could compile fine. I was using an old gcc version (mingw of
the repository uses gcc 4.2), and when i tried a new mingw version
(with gcc 4.7), the compilation worked fine. Which gcc version ffmpeg
requires?

have to put ffmpeg and libav* working on windows :-)

Or not... The error's reappeared, and the only thing I did was
recompile the projeto. Maybe there's a problem with my cameras,
because I also use this same ffmpeg version in my notebook, using
video4linux2 api, and it works fine always... I will investigate it
more.

Hello to all. I've alread compiled libav* with freetype support, and
now I want to write a text over a frame. I've seen there is a filter
for this (drawtext), but I really don't know how to use it. In fact I
don't know how to use libavfilter, because I couldn't find any
tutorials on the Internet.
ffmpeg as superuser?
There is no requirement to build ffmpeg as superuser.
