• How to build pion mediadevices examples with x264 Windows ?

  17 mai 2022, par NO_GUI

  I am trying to build the pion mediadevices webrtc example utilizing x264 as my video encoder. I am building on a Windows 10 PC. The pion/mediadevices library utilizes pkg-config to locate x264 to build the program. I keep getting this error when building though :

  


  # pkg-config --cflags  -- x264
Package x264 was not found in the pkg-config search path.
Perhaps you should add the directory containing `x264.pc'
to the PKG_CONFIG_PATH environment variable
No package 'x264' found
pkg-config: exit status 1


  


  I downloaded the source code for x264, but there is no x264.pc included. And from my research, it appears x264.pc is only included with libx264. I can't find any way to get libx264 on Windows either. Lastly, what is x264.pc, and what is a .pc file ?
Thanks for the help !

  


  Edit : I think I have to build the x264 library first, and I almost got it to work. MinGW was able to compile x264 and give me the x264.pc. But it was all compiled in 32bit, how can I compile the x264 library for 64bit on windows ?

  


• Video encoding libraries for Windows

  ffmpeg is a widely used cross-platform library. But it doesn't support Visual C++, meaning you have to jump through hoops.

  And considering they say the following, it's clear they don't give $0.02 about MSVC users and that makes me uncomfortable for a serious project.. how can one of the most widely used cross-platform libraries not support the most common toolset on the most common OS ?

  There have been efforts to make FFmpeg compatible with MSVC++ in the
  past. However, they have all been rejected as too intrusive,
  especially since MinGW does the job adequately. None of the core
  developers work with MSVC++ and thus this item is low priority. Should
  you find the silver bullet that solves this problem, feel free to
  shoot it at us.

  We strongly recommend you to move over from MSVC++ to MinGW tools.

  It seems unlikely all the Windows developers are doing all this messing about, so are there more Windows-friendly libraries around ?

• ffmpeg windows av_interleaved_write_frame() : Operation not permitted failure

  26 janvier 2021, par Purgoufr

  I'm trying to share my computer's camera with the remote computer. Local machine is linux(ubuntu 20.04.1) and remote machine is windows 10. I created virtual camera in windows machine with use OBS virtual cam and I want to share camera from local to remote machine. I could start stream from local linux machine and I got stream via windows machine. But when I try to write the stream into the virtual camera(output device), I get the error av_interleaved_write_frame (): Operation not permitted.

  


  The command I wrote on the Windows side is as follows :

  


  ffmpeg.exe -f mpegts -i udp://192.168.5.5:5010 -c:v rawvideo -r 30 -pix_fmt yuyv422 -s 1280x720 -f sdl "OBS-Camera"


  


  The error message is as follows :


  


  Extra Info1 : In my experiments, if both the local and remote machines are Linux, it works successfully.

  


  Extra Info2 : I can view the stream that I received on windows side(remote) with the command ffplay.exe udp: //192.168.5.5: 5010.

  


  Do you have any suggestion ?
