  • Linker command failed with exit code 1 when building ffmpeg static libraries

    19 juillet 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 :
    build.gradle (Project)

    I have .a files in following locations :

    • %PROJECT_DIR%/app/src/libs/ffmpeg/armeabi-v7a
    • %PROJECT_DIR%/app/src/libs/ffmpeg/armeabi-v7a-neon
    • %PROJECT_DIR%/app/src/libs/ffmpeg/x86

    It doesn’t look to me that linker misses files themselves. (I get different out put if I misplace them.)

  • Error initializing filter 'amovie' when Join multiple files and add background music, watermark

    I am doing concatenation of multiple videos with adding background music and watermark at the same time (see below)

    


    [-y, -i, 012.mp4, -i, 011.mp4, -i, 010.mp4, -i, 009.mp4, -i, 008.mp4, -i, 007.mp4, -i, 006.mp4, -i, 005.mp4, -i, 004.mp4, -i, 003.mp4, -i, 002.mp4, -i, 001.mp4, -i, 000.mp4, -i, /storage/emulated/0/FXMotion/.cache/.watermark/logo_watermark.png, -filter_complex, [0:v][0:a][1:v][1:a][2:v][2:a][3:v][3:a][4:v][4:a][5:v][5:a][6:v][6:a][7:v][7:a][8:v][8:a][9:v][9:a][10:v][10:a][11:v][11:a][12:v][12:a]concat=n=13:v=1:a=1[video][audio];[13:v]scale=320:-1[watermark];[video][watermark]overlay=main_w-overlay_w-10:main_h-overlay_h-10[vw];amovie=/storage/emulated/0/Download/Afro B - Drogba (Joanna) Prod by Team Salut [Official Music Video].mp3:loop=0,asetpts=N/SR/TB,aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo[bgmusic];[audio]aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=0[fmaudio];[fmaudio][bgmusic]amerge=2,pan=stereo|c0code>

    


    When I run the above command, it has an error :

    


    [Parsed_amovie_3 @ 0x816c5c00] Failed to avformat_open_input '/storage/emulated/0/Download/Afro B - Drogba (Joanna) Prod by Team Salut'

Error initializing complex filters.
No such file or directory
Conversion failed!


    


    I don't know why it happened, is it a bug of amovie filter ?

    


    how to solve it ?, thank advance.
