Looking for Sox (Sound eXchange) libs port for android
5 octobre 2016, par azure313I'm new to mobile development, and i'm developing a mobile application with sound effect functions. I find out that Sox (Sound eXchange) is very strong in desktop environment, and very easy to use, but it didn't have any libs Port for Android.
Does anyone know how to port SoX to Android or is there any other libs instead?
I already try ffmpeg, but it didn't have Reverb effect, so i switch to SoX.
Thank.

Convert video file to m2v using FFmpeg
5 octobre 2016, par utdevHow can I convert a video file
video.mpgto a
video.m2vplus a
'video.mp2'
file?
Thus the
video.m2vfile shall have no audio stream, I read thatvideo.m2vfiles do not have an audio stream, but I am not sure.Edit I used Nilz11 command:
ffmpeg -i input.mpg -codec:v mpeg2video out.m2vand it created me and
.m2v, but mydvdauthroingtool still gives me an error, if I useVLCto convert the.mpgfile to an .m2v file the dvdauthoring tool gives me none, does someone know why this is happening?Edit: I compared Both files
and what I found out is that the file which did not work had a bitrate of :
0
and the file which did work had a bitrate of:
8000
I am not sure but this is the only difference I found between these two files.
Edit
Another thing I have to mention is that the
.m2vfile has to be DVD conform. -
FFmpeg Android Video cropping speed and perfomance [duplicate]
5 octobre 2016, par kishore jethavaThis question already has an answer here:
- Fast Video Compression on Android 2 answers
FFmpeg15 seconds video takes 15 seconds to crop. How can we reduce this cropping time with command or some other tricks?I have refereed this question but didn't helped.
Here is code
final FFmpeg ffmpeg = FFmpeg.getInstance(getActivity()); try { ffmpeg.loadBinary(new LoadBinaryResponseHandler() { @Override public void onStart() {} @Override public void onFailure() {} @Override public void onSuccess() { Log.i(TAG, "FFMPEG Success "); try { /*Logic for cropping the original video to a square video depending of the orientation of the original video*/ //Command for cropping square video String[] cmd = {"-i", "path/source.mp4", "-vf", "scale=720:ih*720/iw, crop="720:720:0:0, "-preset","ultrafast","-strict","experimental","-vcodec","libx264","-preset","ultrafast","path/destination.mp4"}; // Execute cropping of video ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() { @Override public void onStart() { } @Override public void onProgress(String message) { Log.i("Square", "progress : " +message); } @Override public void onFailure(String message) { Log.i("Square", "total fail : " + message); } @Override public void onSuccess(String message) { Log.i("Square", "Cropped video created."); } @Override public void onFinish() { } }); } catch (FFmpegCommandAlreadyRunningException e) { // Handle if FFmpeg is already running } } }); } catch (FFmpegNotSupportedException e) { // Handle if FFmpeg is not supported by device }Logcat

How to stretch the WAV file to the same video length ?
5 octobre 2016, par Michael HeubergerSo yeah, having a tricky ffmpeg issue here.
In my app I'm encoding a video based on image frames and add a WAV file for the sound from the same source but through a different web socket. It can happen that the WAV file doesn't always have exactly the same length as the video based on those images + fps (plus minus few seconds).
How can I tell ffmpeg to "stretch" the input WAV file to have it the same length as the video?
In short:
images (i) + WAV (w) = final video (v)length(w) != length (v)... which is causing problems.Here an example ffmpeg command I am currently using:
ffmpeg -f image2 -thread_queue_size 512 -framerate 21.5 -i /frames/%d.webp -i videomail_preview.wav -y -acodec aac -strict experimental -ac 1 -vcodec libx264 -crf 16 -preset fast -profile:v baseline -pix_fmt yuv420p -loglevel warning -movflags +faststart videomail_good.mp4 -acodec libvorbis -ac 1 -vcodec libvpx -crf 8 -deadline good -cpu-used 1 -pix_fmt yuv420p -loglevel warning -movflags +faststart videomail_good.webm
Any suggestions/trick I am unaware of?
