• Writingminds ffmpeg 64 bit architecture support

  23 décembre 2019, par YadavK

  I am using FFMpeg in one of my project for audio video mixing and it is working fine.

  Now I have requirement for 64-bit architecture support so i have generated .so files for 64-bit architecture support. Now the problem is like in java code there is a class CpuArch.java in which some architecture are define with some alphanumeric value like below :

  x86("0dd4dbad305ff197a1ea9e6158bd2081d229e70e"),
  ARMv7("871888959ba2f063e18f56272d0d98ae01938ceb")

  Now I have to add two more value for ARMv8 and x86_64. From where I got these alphanumeric values.
  And one more thing like assets folder contain ffmpeg files During .so file generation nothing updates in assets folder so how could I generate those files for other architecture as well.

  Please help.

  I followed this library for audio video mixing : https://github.com/WritingMinds/ffmpeg-android-java
