I'm trying recording video from camera and receive timestamp when frame received. I want to extracting timestamp each frame on Windows. And I'm trying use this ffmpeg commandline. Sync files timestamp with ffmpeg
ffmpeg -f dshow -rtbufsize 1500M -video_size 1920x1080 -use_wallclock_as_timestamps 1 -copyts -r 60 -i video="0819-INOGENI 4K2USB3" -r 60 -vf setpts=PTS-STARTPTS -q 4 video4567.avi -c copy -f mkvtimestamp_v2 timings4567.txt
but I want to timestamp based on GetSystemTimePreciseAsFileTime function, not unix epoch time for much better sensitive timer.
So, I'm trying modifying to use GetSystemTimePreciseAsFileTime function mkvtimestamp_v2 code. But it's error when make install processing. like this : libavformat.a(mkvtimestamp_v2.o) : error LNK2019: unresolved external symbol _GetSystemTimePreciseAsFileTime referenced in function _write_packet
It seems like no link win32 api from ffmpeg code.
Is there any way for linking win32 api for ffmpeg code?
thanks :)
