Mix 2 mp3 files with FFmpeg for adroid
1er avril 2017, par Thankgod RichardI am developing something similar to a karaoke app. I have a sound file(beat) and a recorded file(voice) from android mediarecorder. I am trying to mix the two files to become one file that plays the same time. I have set up ffmpeg provided by writingminds and everything is working fine. I am not familiar with ffmpeg commands so searched for and got few commands that can achieve the task for me. This is the code i got :
String files = "-i " + currentFile + " -i " + someFile.getAbsolutePath();
String output = mFileName + "/recorded/test.mp3";
String cmd = "ffmpeg "+files+
" -filter_complex \"aevalsrc=0:d=10[s1];[s1][1:a]concat=n=2:v=0:a=1[ac1];[0:a][ac1]amix[aout]\" -map [aout] -c:a libmp3lame " + output;But it not working. this is the error i got :

Error installing ffmpeg on Ubuntu 8.04 JeOS with Speex
15 novembre 2011, par tubboI'm having an issue installing ffmpeg with Speex support on Ubuntu 8.04 JeOS. After some wandering around in dependency hell I managed to secure the proper libspeex and ffmpeg versions, and it
./configured properly, but when I try to runmake && make install, it fails with the following error :ffmpeg.c: In function ‘opt_recording_timestamp’:
