You can call av_buffersrc_add_frame_flags with NULL for the frame which will signal the end of stream. Then you can loop through av_buffersink_get_frame until it returns AVERROR_EOF (or any error). The loop would typically be: 1. Call av_buffersink_get_frame 2. If no error, process frame 3. if AVERROR_EOF, end your stream avcodec_send_frame will do the same with a NULL for the frame to trigger flushing the codec the same as the filter graph. corey _______________________________________________ Libav-user mailing list Libav-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/libav-user
