/root/project/src/video/VideoStream.cpp:89:48: warning: 'AVStream::codec' is deprecated [-Wdeprecated-declarations]
/root/project/src/video/VideoStream.cpp:123:29: warning: 'void av_free_packet(AVPacket*)' is deprecated [-Wdeprecated-declarations]
/root/project/src/video/VideoStream.cpp:145:73: warning: 'int avcodec_decode_video2(AVCodecContext*, AVFrame*, int*, const AVPacket*)' is deprecated [-Wdeprecated-declarations]
