FFmpeg 被声明为已否决 deprecated(2018 精)

不用再取消SDL检查,不用再添加#pragma warning(disable :4996),下面才是正确的解决方法!!
以下是一些常见的deprecated问题,遇到下述没有列出的问题,可以打开相应的头文件,在里面搜索ctrl+F,会有英文说明的,如下:
 

 

 

 
PIX_FMT_YUV420P -> AV_PIX_FMT_YUV420P


'AVStream::codec': 被声明为已否决:
if(pFormatCtx->streams[i]->codec->codec_type==AVMEDIA_TYPE_VIDEO){
=>
if(pFormatCtx->streams[i]->codecpar->codec_type==AVMEDIA_TYPE_VIDEO){


'AVStream::codec': 被声明为已否决:
pCodecCtx = pFormatCtx->streams[videoindex]->codec;
=>
pCodecCtx = avcodec_alloc_context3(NULL);
avcodec_parameters_to_context(pCodecCtx, pFormatCtx->streams[videoindex]->codecpar);


'avpicture_get_size': 被声明为已否决:
avpicture_get_size(AV_PIX_FMT_YUV420P, pCodecCtx->width, pCodecCtx->height)
=>
#include "libavutil/imgutils.h"
av_image_get_buffer_size(AV_PIX_FMT_YUV420P, pCodecCtx->width, pCodecCtx->height, 1)


'avpicture_fill': 被声明为已否决:
avpicture_fill((AVPicture *)pFrameYUV, out_buffer, AV_PIX_FMT_YUV420P, pCodecCtx->width, pCodecCtx->height);
=>
av_image_fill_arrays(pFrameYUV->data, pFrameYUV->linesize, out_buffer, AV_PIX_FMT_YUV420P, pCodecCtx->width, pCodecCtx->height, 1);


'avcodec_decode_video2': 被声明为已否决:
ret = avcodec_decode_video2(pCodecCtx, pFrame, &got_picture, packet); //got_picture_ptr Zero if no frame could be decompressed
=>
ret = avcodec_send_packet(pCodecCtx, packet);
got_picture = avcodec_receive_frame(pCodecCtx, pFrame); //got_picture = 0 success, a frame was returned
//注意:got_picture含义相反
或者:
int ret = avcodec_send_packet(aCodecCtx, &pkt);
if (ret != 0)
{
prinitf("%s/n","error");
return;
}
while( avcodec_receive_frame(aCodecCtx, &frame) == 0){
//读取到一帧音频或者视频
//处理解码后音视频 frame
}

'av_free_packet': 被声明为已否决:
av_free_packet(packet);
=>
av_packet_unref(packet);
 
 
avcodec_decode_audio4:被声明为已否决:
int ret = avcodec_send_packet(aCodecCtx, &pkt);
if (ret != 0){prinitf("%s/n","error");}
while( avcodec_receive_frame(aCodecCtx, &frame) == 0){
//读取到一帧音频或者视频
//处理解码后音视频 frame
}
