Resize and overlay image on video in android efficiently
29 décembre 2016, par Bhushan LadheI want to resize image and video(2160 x 3840) to a same resolution(540 × 960) and then overlay image on video for whole time. This whole process is similar to capturing video and adding caption to it like snap-chat and saving it.
Since i am successful in doing so using FFMPEG library but it consumes considerable amount of time in processing.
I have searched the internet for other faster operations but no luck. I will post commands that i am using.
//1st command (video size from 59MB to 4MB, about time 110secs)
-i sdcard/VID_20161228_174315.mp4 -vf scale=540:960 sdcard/output540.mp4
//2nd command (image file , size done, time : a sec hence ignored)
-i sdcard/capture.jpg -vf scale=540:960 sdcard/capture540.png
//3rd command (time 80sec)
-i sdcard/output540.mp4 -i sdcard/capture540.png -filter_complex overlay=0:0 -r 30 sdcard/output_overlay.mp4So here using -preset and copying same audio from source did not work as expected.
Questions :
1) Should i use specific codec ?
2) How to achieve Minimum time for processing ?
3) Will applying multiple threads help ? If yes then how ? I want this process to work in background even if app is closed.
4) All other options that can combine to make an efficient solution ?
Log for 3rd command :

Revision 69399 : On refait les critères dans l’inclusion des graphiques, mais on n’affiche ...
25 janvier 2013, par rastapopoulos@… — LogOn refait les critères dans l’inclusion des graphiques, mais on n’affiche cette inclusion que s’il n’y a pas un trop grand nombre de points ! (là 2000 en dur, complètement au hasard).
En vrai il faudrait surtout que les graphiques ne s’affichent qu’avec une pagination mois par mois, un truc dans ce genre ! -
How to crop video with ffmpeg library in Android ?
23 décembre 2016, par DylanTo crop video in Android app I use ffmpeg library
In SO example I found for cropping the video the following command :
ffmpeg -i in.mp4 -filter:v "crop=out_w:out_h:x:y" out.mp4
I created a String array :
String[] cmd = "ffmpeg", "-i", originalVideoPath, "-vf", "\"crop=" + imageWidth + " :" + imageHeight + " :" + xCoordinate + " :" + yCoordinate + "\"", "-c:a", "copy", croppedVideoPath ;
And I pass this array to execute() method :
try {
ffmpeg = FFmpeg.getInstance(getContext());
ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() {
@Override
public void onStart() {
Log.i(TAG, "onStart: Crop Video started");
}
@Override
public void onProgress(String message) {
Log.i(TAG, "onProgress: " + message);
}
@Override
public void onFailure(String message) {
Log.i(TAG, "onFailure: " + message);
}
@Override
public void onSuccess(String message) {
Log.i(TAG, "onSuccess: " + message);
}
@Override
public void onFinish() {
Log.i(TAG, "onFinish: Video cropping finished");
}
});
} catch (FFmpegCommandAlreadyRunningException e) {
// Handle if FFmpeg is already running
Log.i(TAG, "doInBackground: Exception + Device is not supported");
}The log result is :
