ffmpeg udp capture not working

27 février 2017, par user3172852

I have confirmed that there is incoming UDP packets at port 5968 of my computer with wireshark.
However when I try to capture these packets with ffmpeg. After exiting (ctrl+c) I get no output, the output file is not even written to disk. This is what my terminal looks like.

I am streaming live feed of a webcam from PC A to PC B, both connected to a router. I am streaming the video using ffmpeg and I have the output of the commands I use at A and B as follows,

I have skipped few lines of output as there are many frames. So if you see at the end of output on both A and B sides and look at the number of I, P and B frames,the number of P and B frames on receiver B is more than that at sender A. Can anyone please tell me why there is a change in the number of frames ?

ffmpeg build with msys2 + VS2017 hang

20 décembre 2019, par lucky1928
I am using windows10 + MSVC2017 Community + MSYS2 to build ffmpeg 4.0.1 with below steps :
1. Start a Visual Studio 2017 "Developer Command Prompt"
2. cd into msys64 directory, and then invoke MSYS2
  
  msys2_shell.cmd -msys2 -use-full-path
3. In MSYS2 shell, cd into ffmpeg build directory.
4. run ffmpeg config command :
  
  ./configure --prefix=./install --toolchain=msvc
After press enter with above command line,sounds like it hang there forever.
never print anything out and not exit as well.
