I am using writemind's ffmpeg module (running ffmpeg v3.0.2) http://writingminds.github.io/ffmpeg-android-java/
But I am getting the follow error when executing the command
[NULL @ 0xe93aa000] Unable to find a suitable output format for ' -i "/storage/emulated/0/Android/data/com.charaku.popsical.tv/cache/video_recording.mp4" -i "/storage/emulated/0/Download/132859_aac-group-2.mp4" -c:v copy -filter_complex '[1:a] adelay=2500|2500 [delayed]; [0:a] [delayed] amix [out]' -map 0:v -map '[out]' "/storage/emulated/0/Android/data/com.charaku.popsical.tv/cache/mixed_test2.mp4"' -i "/storage/emulated/0/Android/data/com.charaku.popsical.tv/cache/video_recording.mp4" -i "/storage/emulated/0/Download/132859_aac-group-2.mp4" -c:v copy -filter_complex '[1:a] adelay=2500|2500 [delayed]; [0:a] [delayed] amix [out]' -map 0:v -map '[out]' "/storage/emulated/0/Android/data/com.charaku.popsical.tv/cache/mixed_test2.mp4": Invalid argument
The command is supposed to mix the audio of a video file with the audio of another audio file to produce a new video file.
