As alternative to this, any video libavfilter task should be OK
(e.g. port a filter from MPlayer/libmpcodecs or write a new one), note
that vf_imlib.c is *not* a valid qualification task (see
https://roundup.ffmpeg.org/issue302), this should help you to get
confident with the FFmpeg/libavfilter API.
I especially recommend: a deinterlace filter (check the code in
libavcodec/imgconvert.c), a libfreetype wrapper (check as reference
vhook/drawtext.c in ffmpeg-0.5).
Ask here or on IRC if you have questions.
I am planning to do the deinterlace, libfreetype first and then
continue with this.
Good. Feel free to join the discussion on ffmpeg-devel regarding the
libavfilter API, consider that as part of the qual task.
Hi All,
The vf_drawtext filter is almost done but I am having problems linking
in the freetype libraries. I attempted the attached changes to the
ffmpeg Makefile but I see the following error :
ffmpeg/libavfilter/libavfilter.a(vf_drawtext.o): In function `draw_text':
ffmpeg/libavfilter/vf_drawtext.c:422: undefined reference to
`FT_Get_Kerning'
What am I doing wrong?
Thanks
