some problem compiling on Ubuntu 9.04

Bug Reports

I found some problems building breve:

first is because of new version of libavformat - there is no img_convert()

I suggest to change simulation/movie.cc (hope it will work)

//..... int slMovieEncodeFrame( slMovie *m ) { AVCodecContext *c; int size;


        if ( !m ) return -1;
        c = m->_context;
        /*

         * Colorspace conversion from RGB to codec's format (likely YUV420P).

         * OpenGL's RGB pixel format is RGB24 in lavc.

         */
        /*it's not working now with new libavformat versions =(

        img_convert(( AVPicture * )m->_yuv_pic, c->pix_fmt,

                    ( AVPicture * )m->_rgb_pic, PIX_FMT_RGB24, c->width, c->height );

        */
        /*this should work =)

        begin of img_convert() replacement*/

        static int sws_flags = SWS_BICUBIC;

        static struct SwsContext *img_convert_ctx;
        img_convert_ctx = sws_getContext( c->width,

                                        c->height,

                                        PIX_FMT_RGB24,

                                        c->width,

                                        c->height,

                                        c->pix_fmt,

                                        sws_flags, NULL, NULL, NULL);
        sws_scale( img_convert_ctx,

                m->_rgb_pic->data,

                m->_rgb_pic->linesize,

                0,

                c->height,

                m->_yuv_pic->data,

                m->_yuv_pic->linesize);
        sws_freeContext(img_convert_ctx);

        /*end of img_convert() replacement*/
        /* Encode the frame yuv_pic storing the output in enc_buf. */
        size = avcodec_encode_video( c, m->_enc_buf, m->_enc_len, m->_yuv_pic );
        if ( size ) fwrite( m->_enc_buf, 1, size, m->_fp );

return 0; } //....

and in include/breve/movie.h changed to:
//...... extern "C" { #include #include } //......
also add -lswscale to makefile

but I can't test it beacause I still have problems with
