Compress video with ffmpeg4android library
30 mars 2015, par Huy TowerI tried to follow ffmpeg4android library, and I get the problem when compressing the video, as the Log image below.
I use intent to transfer to Compressing Media class,
Intent intent = new Intent(this, CompressingMedia.class);
intent.putExtra("file_path", mLlItems.get(0).getPath());
startActivity(intent);This is the class was transfered to :
public class CompressingMedia extends BaseWizard {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = getIntent();
Log.d(Prefs.TAG, "path " + intent.getExtras().getString("file_path"));
// /storage/emulated/0/DCIM/Camera/VID_20140312_090612.mp4
String command = "ffmpeg -y -i " + intent.getExtras().getString("file_path") +
" -strict experimental -s 320x240 -r 15 -aspect 3:4 -ab 12288 -vcodec mpeg4 -b 2097152 -sample_fmt s16 /sdcard/out.mp4";
// if you want to change the default work location (/sdcard/videokit/) use the uncomment the below method.
// It must be defined before calling the copyLicenseAndDemoFilesFromAssetsToSDIfNeeded method,
// in order for this method to copy the assets to the correct location.
// setWorkingFolder("/sdcard/videokit/");
// this will copy the license file and the demo video file.
// to the videokit work folder location.
// without the license file the library will not work.
copyLicenseAndDemoFilesFromAssetsToSDIfNeeded();
commandStr = command;
setCommand(commandStr);
runTranscoing();
}
}Although I received the notification Transcoding Successfully, but it looks like the capacity of file after compressing is always be 0. (the log in the bottom of images)
I don’t know the result as image below is good or not, I can not get the expected result - The video was compressed totally successfully.
Someone know why after compressing the file is always be 0, please tell me. Thanks.
