Watching this code: http://www.csps.com.ar/mms/plugins/output/mpeg/mpeg.cpp I found this way: static AVPicture pic; ... // In some way, you already got var "pic" initialized // Define your AVFrame AVFrame *yuv_buf; /* prepare an AVPicture out of our buffers */ yuv_buf = avcodec_alloc_frame(); /* the lower the better quality, but also larger images => slower to transfer */ yuv_buf->quality = 0; /* copy the data from avpicture to avframe */ for (int i=0; i<4; ++i){ yuv_buf->data[i]= pic.data[i]; yuv_buf->linesize[i]= pic.linesize[i]; } Now you got the content of AVPicture pic in AVFrame yuv_buf. I haven't test this code, but I guess it should work! -- ============================ Gustavo Gonzalez [email protected] ============================ _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
