i wanna trim video in android java
2 mars 2020, par israfilllI used this library implementation ’com.writingminds:FFmpegAndroid:0.3.2’.
But i get an error.CANNOT LINK EXECUTABLE "/data/user/0/com.example.newapplication/files/ffmpeg" : "/data/data/com.example.newapplication/files/ffmpeg" has text relocations (https://android.googlesource.com/platform/bionic/+/master/androg-’changes-for-ndk-developers.md#Text-Relocations-Enforced-for-API-level-23)
is there anyone who know reason ?this is code and i just want to trim(cut) video in time range i want. others is not necessary

ffmpeg merge multiple (N) mono audio channels of a MXF video to multiple (M) stereo channels of MP4 video
14 février 2020, par LauraI have an MXF file with 16 audio mono streams and I need to recode it in a mp4 file with 2<=n<=16 channels merging input streams, e.g. input channels 1 and 2 on output channel 1 and 9 and 10 on output channel 2. This job will be done with ffmpeg. I read the documentation and found the amerge and amix filters that would be nice, but they output one channel only. Is there any solution for this problem ?
Thanks,
LauraFind below the output of ffprobe on mxf file :
