v210调查

7yuv 打开uyvy文件时选项

 

 

 

 

 

 

7yuv 打开v210格式 

 

 

 

 

 

通过ffmpeg 将v210编码为其他 

ffmpeg  -r 25 -vcodec v210 -f image2pipe -pix_fmt yuv422p10le -frame_size 5529600 -s 1920*1080 -i my_test.yuv -vcodec libx264 -b:v 8000k  -r 25  -f  mpegts v210.ts

 

ffmpeg -i v210.ts -vcodec v210 -pix_fmt yuv422p10le my_test.yuv 将上一步生成的文件再转回v210 的yuv

hevc 解码导出的变量

10bit 输出

解码器界面需要增加一个选项

output_with_10_bit

编码器需要增加一个10bit输入

input_with_10_bit

 

 

ffmpeg 中获取metadata

AVFrameSideData *av_frame_get_side_data(const AVFrame *frame,
                                        enum AVFrameSideDataType type)
{
    int i;

    for (i = 0; i < frame->nb_side_data; i++) {
        if (frame->side_data[i]->type == type)
            return frame->side_data[i];
    }
    return NULL;
}
