• FFmpeg error : Failed to resolve hostname

  29 octobre 2016, par David Barishev

  I’m using FFmpeg on android, and i have a strange error show up, that does not occur when i’m executing it on my linux VM.
  I’m using FFmpeg Static Builds, from here.
  I am using the stable 3.1.5 x86_64 build on the emulator and the linux VM.

  Here is the log :

  Since im using the same build for each platform, what is blocking the android one from working ? Is it something with android platform not allowing connections from static libraries ?

• System reboots during ffmpeg tool installation

  I have enabled QSV with reference of the streambuilder’s enabling-iqsv docs.

  I have installed ffmpeg with —enable-nonfree —enable-libmfx configurations, configuration command was successfully done.Then, I invoke make and our server gets hanged in few seconds and it will gets rebooted automatically.

  I feel it might be compilation issue with make script.

• How can I reset the path of FFMPEG in Java ?

  4 avril 2017, par Figgyja

  I accidentally set the path for FFMPEG to a different folder, and I can’t change it back.

  I’m using Processing (the API and its IDE) and the user created Video Export library to capture and write an mp4 video file. The library required FFMPEG, so I downloaded and installed it. After I installed it, I ran the code, and the library called Java to request the path of FFMPEG. I wrongly set the path to a different folder, which I eventually deleted. I knew I set it to the wrong folder, and ran the code again to see if I could trigger the Java prompt again to reset the folder.

  The console response I received was : (I’m sure most of it doesn’t have to do with the actual issue. However, I wanted to show all of it in case it somehow does.)

  I need to find a way to reset the path of FFMPEG that Java has. I have tried uninstalling and reinstalling the library, but I haven’t tried Java (I don’t want to mess with anything it has in its current state).

  P.S. The file listed at the end of the console response (basic.mp4.txt) was empty because it had not begun writing to the file yet.
