• Using ffmpeg ffprobe with Visual C++

  11 juillet 2015, par astracat111

  I have the following command line that gives me the duration of a video file :

  ffprobe.exe -i Video.mp4 show_entries format=duration -v quiet -of csv="p=0"

  When I run this, I get back the duration of my video successfully, running it from a command prompt. Now, I’m kind of a beginner with C++, so I’m not sure how I could get that duration to be put into a float inside of my program. I’ve looked through a lot of articles and question and answer forums online and I’ve found possible answers with...using stdout/stdin to grab the information...? I’m not sure.

  My strategy right now is to use CreateProcess() to run the process, then WaitForSingleObject(), then somehow use some command to grab the output data from the ffprobe process. Perhaps the data I’m looking for can be retrieved through the CreateProcess() function ? I feel like I’m very close, but I’m in serious need of help with this...

  As a side note, since I’m using Visual C++ Express 2010, I do not have access to MFC.

  If anyone could lead me in the right direction to this information it would be greatly appreciated.

• How to install ffmpeg and an app together on a Mac ?

  30 juin 2016, par Patrick

  I have an electron app built and packaged for macOS in a .app file. The app requires ffmpeg to be installed on the end-user’s computer to be used.

  Currently, I’ve had to manually install ffmpeg on each end-user’s computer to run the app.

  I want to distribute the app online with an easy installer for both ffmpeg and the app. I’ve seen .dmg files which allows you to drag the .app into the applications folder easily, but the ffmpeg dependency is still absent in the installation process.

  How can I install ffmpeg and the app together on a mac ?

  Perhaps including the ffmpeg build in the .app content is a solution as well.
  This may not be possible though because a relevant question mentions there are only abstractions of the ffmpeg CLI instead of something that can directly use ffmpeg.
