Error initializing filter 'amovie' when Join multiple files and add background music, watermark
25 août 2020, par Nguyễn TrọngI 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 :

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


how to solve it ?, thank advance.

Linker command failed with exit code 1 when building ffmpeg static libraries
19 juillet 2017, par Wilsom SandersI’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.

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)// Top-level build file where you can add configuration options common to all sub-projects/modules.

jcenter()

// in the individual module build.gradle files
}
}
