An experiment introducing a bilateral loop filterAdds a framework to incorporate a parameterized loop
postfilter in the coding loop after the application of the
standard deblocking loop filter.The first version uses a straight bilateral filter
where the parameters conveyed are just spatial and
intensity gaussian variances.Results on derflr :
+0.523% (only with this experiment)
+6.714% (with all expts other than intrabc)Change-Id : I20d47285b4d25b8c6386ff8af2a75ff88ac2b69b

ffmpeg shell script globbing
10 novembre 2015, par AD0AEI have a pretty straight forward question. I have a bunch of individual directories that are labeled as
./001 ./002 ... ./201
within each directory contains files that have the identifier*_IO.PNGI can use the shell command :
ffmpeg -framerate 20 -pattern_type glob -i './066/*IO.PNG' -c:v libx264 -pix_fmt yuv420p 066.mp4and this works great. It does exactly what I want.However, I tried to write a shell script, which is below but this does not work. It seems to be loading individual files instead of all of them at once. Any help would be appreciated.
#!/bin/bash
for i in {1..5}
do
FILE=$(printf %03d $i)
echo " This file: $FILE"
infile='./$FILE/*IO.PNG'
echo $infile
ffmpeg -framerate 20 -pattern_type glob -i $infile -c:v libx264 -pix_fmt yuv420p './$FILE.mp4'

Running ffmpeg command on Android results in "Unable to find a suitable output format for ' -map 0:v:0 -map 1:a:0'"
5 juin 2017, par Akash DubeyI am using this command for replacing audio of video and genrate new video having new audio. Here file1 is my video.mp4, file2 is my audio.mp3 and output would be the output.mp4 :
complexCommand = new String[]{"-y", "-i", file1.toString(), "-i", file2.toString(), "-c", "copy", " -map 0:v:0 -map 1:a:0", rootPath + "/output.mp4"};Below is My code :
private void changeAudioofVideo(String selectedUri, String videoPath) {
String[] complexCommand;
File f = new File("/storage/emulated/0");
if (!f.getParentFile().exists())
f.getParentFile().mkdirs();
if (!f.exists())
try {
f.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
file1 = new File(videoPath);
if (file1.exists()) {
Log.d("yes", "File 1 exists");
} else {
Log.d("no", "File 1 not exists");
}
file2 = new File(selectedUri);
if (file2.exists()) {
Log.d("yes", "File 1 exists");
} else {
Log.d("no", "File 1 not exists");
}
String rootPath = f.getPath();
complexCommand = new String[]{"-y", "-i", file1.toString(), "-i", file2.toString(), "-c", "copy", " -map 0:v:0 -map 1:a:0", rootPath + "/output.mp4"};
FFmpeg ffmpeg = FFmpeg.getInstance(this);
try {
//Load the binary
ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
@Override
public void onStart() {
}
@Override
public void onFailure() {
}
@Override
public void onSuccess() {
}
@Override
public void onFinish() {
}
});
} catch (FFmpegNotSupportedException e) {
// Handle if FFmpeg is not supported by device
Toast.makeText(getApplicationContext(), "Not Supported by Device", Toast.LENGTH_LONG).show();
}
try {
final String finalRootPath = rootPath;
ffmpeg.execute(complexCommand, new FFmpegExecuteResponseHandler() {
@Override
public void onSuccess(String message) {
Log.d("Success", message);
Toast.makeText(getApplicationContext(), "Successful" + finalRootPath.toString(), Toast.LENGTH_LONG).show();
Uri path = Uri.parse(finalRootPath + "/output.mp4");
playVideo(path.toString());
}
@Override
public void onProgress(String message) {
Log.d("progress", message);
pd.show();
}
@Override
public void onFailure(String message) {
Log.d("failure", message);
pd.dismiss();
}
@Override
public void onStart() {
Log.d("Start", "merge started");
}
@Override
public void onFinish() {
Log.d("finish", "merge finish");
pd.dismiss();
}
});
} catch (FFmpegCommandAlreadyRunningException e) {
e.printStackTrace();
}
