(C_UDP Socket Programming) How can I convert binary file to video format ?
30 avril 2024, par user24723398I am practicing UDP socket programming. My code's functions are below.


- 

- Connect Server-Client and send "hello" message each other (it is working).
- Then Server is sending video file to client (problem).






Transfer video file to client is working. But it is written in binary so I can't open the video.


So I try to use ffmpeg to convert the video, but it doesn't work.


Is there something wrong in my code ? How can I transfer a received file to a video file ?


My environment is MacOs.
