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.
Reading the libavfilter/avcodec.h file I saw I have to use avfilter_fill_frame_from_video_buffer_ref(AVFrame*, const AVFilterBufferRef *), and til now I have the AVFrame, but I don't have a AVFilterBufferRef object. How can I create it and how use it with the drawtext filter? Does the filter depend on the frame's PixelFormat? Thx to all. _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
