static struct SwsContext *swsContext; swsContext = sws_getContext(c->width, c->height,PIX_FMT_NV21, c->width, c->height, PIX_FMT_YUV420P, SWS_FAST_BILINEAR, NULL, NULL, NULL); avpicture_fill((AVPicture*)picture, data, PIX_FMT_NV21, c->width, c->height); avpicture_fill((AVPicture*)outpic, outbuffer, PIX_FMT_YUV420P, c->width, c->height); sws_scale(swsContext, picture->data, picture->linesize, 0, c->height, outpic->data, outpic->linesize); sws_freeContext(swsContext);
