  • Android ffmpeg. Linker command failed with exit code 1

    8 juin 2017, par Wilsom Sanders

    I’m trying to build ffmpeg static libraries and link them to an android project in order to implement a video player. Goal is to make a player capable of receiving video file from various sources similar to p2p file sharing networks. (target api is 21 level which is 1 level short from supposed official solution with MediaSource)

    I managed to compile ffmpeg from this repo (all the code used as-is) but later i got stuck on a linking problem. Whenever I try to compile I get list of ffmpeg methods called in my code and a short eloquent message :

    Linker command failed with exit code 1

    I have no clue how to pass -v flag to the linker in android studio. Would be great if somebody hinted me that.

    I use android studio, build with gradle and cmake.

    There’s my files :

    I don't have deeper experience with ffmpeg conversions and codecs. It seems to me that this is a frames related problem. Do you have a clue why does it fail ? What options should I use in ffmpeg command to solve this ? Thanks for any help.
