While building 'ffmpeg' 4.0.2 and above, missing function
'ffio_open_dyn_packet_buf'. Due to this I am unable to compile my project.
I spend my whole week to find the solution but didn't get success. When
searching this function in code than it is available on source code.But
when build from sorce code this function is missing. Please guide me what
I need to do.
./libavformat/aviobuf.c:1396:int
ffio_open_dyn_packet_buf(AVIOContext **s, int max_packet_size)
./libavformat/avio_internal.h:120:int
ffio_open_dyn_packet_buf(AVIOContext **s, int max_packet_size);
./libavformat/movenchint.c:430: if ((ret =
ffio_open_dyn_packet_buf(&rtp_ctx->pb,
./libavformat/rtpenc_chain.c:85: ret =
ffio_open_dyn_packet_buf(&rtpctx->pb, packet_size);
./libavformat/rtspenc.c:158: * ffio_open_dyn_packet_buf.
So by writing the interleaving header
./libavformat/rtspenc.c:178: return
ffio_open_dyn_packet_buf(&rtpctx->pb, RTSP_TCP_MAX_PACKET_SIZE);
I have below environment:
OS : Windows 10
MSVC : Visual Studio 15 with Windows SDK 10.0.17763.0
MSYS2 : MINGW32_NT-10.0-WOW
Getting below error:
server-ffmpeg.obj : error LNK2019: unresolved external symbol
_ffio_open_dyn_packet_buf referenced in function "int __cdecl
ff_server_send_packet_1(char const *,void *,int,struct AVPacket
*,__int64,struct timeval *)"
(?ff_server_send_packet_1@@YAHPBDPAXHPAUAVPacket@@_JPAUtimeval@@@Z)
rtspserver.obj : error LNK2019: unresolved external symbol

*)" (?rtspserver@@YAPAXPAX at Z)
server-ffmpeg.dll : fatal error LNK1120: 1 unresolved
externals
Please guild me to achieve above result.
Thanks
