Hi all,
I'm trying to use the drawtext filter to overlay some text on recorded
footage. I've compiled and installed ffmpeg-soc/libavfilter from svn
repository. I have:
FFmpeg version SVN-r25657, Copyright (c) 2000-2010 the FFmpeg developers
built on Nov 11 2010 23:05:59 with gcc 4.4.4
configuration: --prefix=/usr --enable-shared --enable-static
--enable-nonfree --enable-gpl --enable-libfreetype --enable-swscale
--disable-ffserver --enable-libvpx --enable-libx264 --enable-avfilter
--enable-libopenjpeg
I'm using the following command line:
ffmpeg -fflags +genpts -f mjpeg -r 5 -s 640x480 \
-i http://localhost:8081/?action=stream \
-vcodec mpeg4 -b 1000000 -r 5 \
-vf drawtext="fontfile='/usr/share/font/TTF/LiberationSansRegular.ttf' \
:fontsize=18:fgcolor=0xFFFFFF:bgcolor=0x333333:x=10:y=5 \
:text='camera 1 | \%H\:\%M\:\%S | \%d-\%m-\%Y'" \
/home/cctv/test-overlay.avi
Ignore the backslash on the next line - this is from my email software.
The overlay does appear in the recorded footage - but the problem I have
is that "bgcolor" doesn't seem to work. There is simply no background
for the overlay. Whatever value I put there - it has no effect
whatsoever. "fgcolor" does work, however. Also - the command doesn't
spew any errors.
Is this by design (i.e. - am I missing something in my syntax) - or is
it a bug? Should I file a bug report somewhere?
Sebastian
