• FFMPEG for Android - missing alsa format

  24 août 2012, par user1545779

  @rowntreerob has an android-ffmpeg implementation that build successfully using the default file settings.

  When you remove disble-avdevice and disbale-devices from the configure_ffmpeg script, ndk-build fails. The following is the error message :

  CP ffmpeg
  STRIP ffmpeg

  make : ** [/home/jasongipsyblues/android-ffmpeg/Project/obj/local/armeabi-v7a/ffmpeg] >Error 1

  Please pardon my poor formating skills, I still dont get the formating thing. It appears the deletion of the references is to avdevices is definitely affecting the use of ndk-build.

  All the alsa source files exist in the ffmpeg code. How does one build ffmpeg in such a way that alsa is included in the formats ?

• Setup FFMpegCore in Visual Studio 2019

  27 juillet 2022, par DsiakMondala

  I am confused on the basics of using a library. I understand that there is a library called FFMpeg and a wrapper called FFMpegCore so we can use FFMpeg with C#, correct ? I downloaded both FFMpeg and FFMpegCore and I have them in my project's folder. Although I didn't perceive any class named FFMpegOptions in either of the file's folders.&#xA;I am stuck on how to actually set it up so I can use it in my little project, I never downloaded someone's library before. Can somebody please walk me though the motions of connecting the three of them together ?

  &#xA;

  So far I experimented with :

  &#xA;

  &#xA;
  • Add a reference to my project, but there doesn't seem to be any .dll, .tlb, .olb, .ocx or .exe files to add

  &#xA;

  • Add an existing project to my solution. There is a project called FFMpegCore.csproj but adding it raises a missing SDK error. Weirdly enough, opening the same project as a standalone doesn't raise any issues which makes me thing the operation I am trying is inadequate.

  &#xA;

  &#xA;

  I am sure this is a silly and easy setup to perform but I just don't know enough to find a solution.
