how to download file in given path in onFileMessageReceived by using agora sdk in android

code at receiver end
#Override
public void onFileMessageReceivedFromPeer(RtmFileMessage rtmFileMessage, String s) {
runOnUiThread(() -> {
if (s.equals(toProfID)) {
// String path = context.getFilesDir().getAbsolutePath() + "/" + rtmFileMessage.getFileName();
final String cacheFile = getCacheFile(context, rtmFileMessage.getFileName());
Log.d("onFileMessageReceived", cacheFile);
RtmRequestId requestId = new RtmRequestId();
mRtmClient.downloadMediaToFile(
rtmFileMessage.getMediaId(),
cacheFile,
requestId,
new ResultCallback<Void>() {
#Override
public void onSuccess(Void aVoid) {
massageList.add(0,new ChatItem(ChatItem.LayoutSix, "", rtmFileMessage.getFileName(), cacheFile, Time(), false));
chatAdapter.notifyDataSetChanged();
recyclerView_list.scrollToPosition(0);
}
#Override
public void onFailure(ErrorInfo errorInfo) {
Log.d("onFailure", "onFileMessageReceived" + errorInfo.toString());
}
}
);
}
});
}
path as below
public static String getCacheFile(Context context, String id) {
File parent = new File(context.getCacheDir(), CACHE_DIR);
if (!parent.exists()) {
parent.mkdirs();
}
return new File(parent, id).getAbsolutePath();
}
unable to download this file from media id
**want to download recived document. i am opening this document with respect formate . .pdf is openinig but actualy file is not open. i dont know issue **

use this code for download
public static String getCacheFile(Context context, String id) {
File parent = new File(context.getExternalFilesDir(Environment.DIRECTORY_DOCUMENTS),
"YourAppDirectory");
if (!parent.exists()) {
parent.mkdirs();
}
return new File(parent, id).getAbsolutePath();
}
}

The FFmpeg just show the number form the input text (no characters , just numbers) error=13, Permission denied

I was trying to use FFmpeg to create a video form gif and audio, on Android 10, doesn't work
The code is working fine on android 9 and below, and not work 10 and above
the Cmd, as I mentioned it is work so good on android 9 and below
String[] cmd = new String[24];
cmd[0] = "-i";
cmd[1] = audio.getPath();
cmd[2] = "-ignore_loop";
cmd[3] = "0";
cmd[4] = "-i";
cmd[5] = image_path;
cmd[6] = "-vf";
cmd[7] = "scale=trunc(iw/2)*2:trunc(ih/2)*2";
cmd[8] = "-filter:v";
cmd[9] = ayat_drawer + qara_draw;
cmd[10] = "-vcodec";
cmd[11] = "libx264";
cmd[12] = "-pix_fmt";
cmd[13] = "yuv420p";
cmd[14] = "-r";
cmd[15] = "25";
cmd[16] = "-preset";
cmd[17] = "ultrafast";
cmd[18] = "-c:a";
cmd[19] = "aac";
cmd[20] = "-b:a";
cmd[21] = "128k";
cmd[22] = "-shortest";
cmd[23] = outputLocation.getPath();
The Java code :
FFmpeg mFFmpeg = FFmpeg.getInstance(context);
try {
mFFmpeg.execute(cmd, new ExecuteBinaryResponseHandler() {
#Override
public void onProgress(String message) {
super.onProgress(message);
callback.onProgress(message);
}
#Override
public void onSuccess(String message) {
super.onSuccess(message);
Utils.refreshGallery(outputLocation.getPath(), context);
callback.onSuccess(outputLocation, "video");
}
#Override
public void onFailure(String message) {
super.onFailure(message);
if (outputLocation.exists()) {
outputLocation.delete();
}
callback.onFailure(new IOException(message));
}
#Override
public void onStart() {
Log.d("TAG", "<ffmpeg>Started command : mFFmpeg " + java.util.Arrays.toString(cmd));
}
#Override
public void onFinish() {
Log.d("TAG", "<ffmpeg>Finished command : mFFmpeg " + java.util.Arrays.toString(cmd));
super.onFinish();
callback.onFinish();
}
});
} catch (FFmpegCommandAlreadyRunningException e) {
Log.e("MAS" , e.getMessage());
e.printStackTrace();
}
I think that because FFmpeg using Asynctask and it is deprecated

I was found a solution by using this code :

ffmpeg Add watermark/text in video on react native

Right now i'm stuck on android part,here is my code
I don't want to define font styling or box it just i found this code somewhere so i just copy pasted it as i don't have any knowledge of ffmpeg, I just want a simple text of right aligned in 2 lines on top of right of the video like this.
I am getting the error in this part of code as the video is getting generated but it does not play and it is of always 262B size
String[] cmd = new String[] {
"-i", path, "-vf", String.format("drawtext=\"fontfile=/systems/fonts/DroidSans.ttf: text='%s': " + "box=1: boxcolor=black#0.5: boxborder=5: x=(w-text_w)/t: y=(h-text_h)/2\"", text), "-codec:a", "aac", out.getAbsolutePath()

FFMPEG in Android doesn't create output file.

I am currently using FFMPEG in my Android project for converting a video file to an audio file.
When I execute converting by FFMPEG library, no error occurs. However, the output file is not created in the folder which I already specified.
Here is my code for generating audio file.
OnConvertButtonClickListener convertButtonClickListener = new OnConvertButtonClickListener() {
#Override
public void onClick(int position) {
Converter.loadFFMpegBinary();
String cmd = CMD_HEAD + videoItems.get(position).getTitle() + CMD_STRICT;
String[] fileDir = videoItems.get(position).getTitle().split(File.separator);
String fileName = fileDir[fileDir.length-1];
String out_audio_file = FileManager.getHomeDir()+ File.separator+ fileName.substring(0, fileName.length()-3)+"aac";
Log.d("tag1", out_audio_file);
cmd = cmd+out_audio_file;
Log.e("tag1", cmd);
String[] command = cmd.split(" ");
Converter.execFFmpegBinary(command);
}
};
This is exeFFmpegBinary method code, and after executing this method, success is displayed in my Log window.
public static void execFFmpegBinary(final String[] command) {
try {
ffmpeg.execute(command, new ExecuteBinaryResponseHandler() {
#Override
public void onFailure(String s) {
Log.d("execFFmpegBinary", "fail");
}
#Override
public void onSuccess(String s) {
Log.d("execFFmpegBinary", "success");
}
#Override
public void onProgress(String s) {
Log.d("execFFmpegBinary", "progress");
}
#Override
public void onStart() {
Log.d("execFFmpegBinary", "start");
}
#Override
public void onFinish() {
Log.d("execFFmpegBinary", "finish");
}
});
} catch (FFmpegCommandAlreadyRunningException e) {
// do nothing for now
Log.d("execFFmpegBinary", "Exception");
}
}
Below is an example of my cmd.
-version -y -i /storage/emulated/0/DCIM/Camera/20180104_031417.mp4 -f aac -ab 192000 -vn /storage/emulated/0/Memento/20180104_031417.aac
Anyone knows why my output file doesn't be created?

I have added audio using ffmpeg may be this will help you.

this.videoWithoutAudioPath = videoWithoutAudioPath;
String currentMilliSecond = String.valueOf(System.currentTimeMillis());
output = Environment.getExternalStorageDirectory().getAbsolutePath() + "/" + context.getResources().getString(R.string.app_name) + "/test/" + currentMilliSecond + ".mp4";
//String cmd = "-y -i " + videoWithoutAudioPath + " -i " + soundPath + " -c:v copy -map 0:v:0 -map 1:a:0 -c:a aac -shortest " + output;
String cmd = "-y -i " + videoWithoutAudioPath + " -i " + soundPath + " -c:v copy -map 0:v:0 -map 1:a:0 -c:a aac -shortest " + output;
encodeAudio(cmd);
}
private void encodeAudio(String cmd) {
String[] command = cmd.split(" ");
if (command.length != 0) {
execFFmpegBinary(command);
} else {
Toast.makeText(context, context.getString(R.string.empty_command_toast), Toast.LENGTH_LONG).show();
}
}
private void execFFmpegBinary(final String[] command) {
try {
ffmpeg.execute(command, new ExecuteBinaryResponseHandler() {

}
#Override

/**

if (deleteOriginalVideo() && deleteWorkingFolder(videoWithoutAudioPath)) {
progressDialog.dismiss();
Intent notificationIntent = new Intent(Utils.LOCAL_BROADCAST_CODE);
notificationIntent.putExtra(Utils.FILE_PATH, output);
LocalBroadcastManager.getInstance(context).sendBroadcast(notificationIntent);
}
}
});
} catch (FFmpegCommandAlreadyRunningException e) {
e.printStackTrace();
}
}
private boolean deleteOriginalVideo() {
boolean success = false;
File file = new File(videoPath);
if (file.exists()) {
success = file.delete();
}
return success;
}
private boolean deleteWorkingFolder(String deletePath) {
File file = new File(deletePath);
File folder = new File(file.getParent());
if (folder.isDirectory()) {
for (File child : folder.listFiles()) {
//noinspection ResultOfMethodCallIgnored
child.delete();
}
}
return folder.delete();
}
}

Always check the log from ffmpeg (assuming your script is working and it is actually being executed). Yours should show an error:
Requested output format 'aac' is not a suitable output format
Replace -f aac with -f adts, or omit the -f option if the output is a normal file name with the .aac extension.
Alternatively, since your MP4 input most likely already contains AAC audio consider stream copying it instead of re-encoding. To do so remove -ab 192000 and add -c:a copy.

(well, I don't have enough karma to post a comment and I'm pretty new to FFmpeg lib)
what I can think of now is always consider giving a SPACE(" ") while concatenating strings in commands for this FFmpeg lib...try following
change:
cmd = cmd+out_audio_file;
To: (mark the space between cmd and out_audio_file)
cmd = cmd+" "+out_audio_file;

ownCloud Android DownloadRemoteFile File Name

I'm trying to download a list of RemoteFiles in Android using ownCloud. I can download the files perfectly fine but I'd like to notify the user when a file finishes. I'm downloading an entire directory:
#Override
public void onRemoteOperationFinish(RemoteOperation operation, RemoteOperationResult result) {
if (operation instanceof ReadRemoteFolderOperation) {
if (result.isSuccess()) {
Toast.makeText(this, "Finished reading folder", Toast.LENGTH_SHORT).show();
for (Object o : result.getData()) {
RemoteFile remoteFile = (RemoteFile) o;
String remotePath = remoteFile.getRemotePath();
File targetDirectory = new File(Environment.getExternalStorageDirectory().getAbsolutePath() +
"/owncloud_download");
downloadHelper.downloadFile(remoteFile, targetDirectory);
}
}
}
if (operation instanceof DownloadRemoteFileOperation) {
if (result.isSuccess()) {
// Notify the user here that the file finished
}
}
}
I've looked at the ownCloud library source but can't seem to find what a DownloadRemoteFileOperation returns as a result other than a boolean indicating success and an HTTP status code. I thought it might be in result.getLogMessage() but that just gives me an HTTP 200 status. How can I get the name of a file that's finished?
Edit: I also looked at result.getData() but that's null in a DownloadRemoteFileOperation.

Here's my workaround for the time being. I didn't want to modify the ownCloud library source (again) so instead I just do a check in onTransferProgress like so:
#Override
public void onTransferProgress(long rate, long transferred, long total, String fileName) {
if (transferred == total) {
runOnUiThread(new Runnable() {
// do the update here, file name is available
}
}
}
Here's another option. I needed the file being uploaded if the upload failed so I modified the ownCloud library source. This way I could return file names in the RemoteOperationResult.
RemoteOperationResult.java:
private String fileName;
public String getFileName() {
return fileName;
}
public void setFileName(String name) {
fileName = name;
}
DownloadRemoteFileOperation.java
#Override
protected RemoteOperationResult run(OwnCloudClient client) {
RemoteOperationResult result = null;
/// download will be performed to a temporal file, then moved to the final location
File tmpFile = new File(getTmpPath());
/// perform the download
try {
tmpFile.getParentFile().mkdirs();
int status = downloadFile(client, tmpFile);
result = new RemoteOperationResult(isSuccess(status), status,
(mGet != null ? mGet.getResponseHeaders() : null));
Log_OC.i(TAG, "Download of " + mRemotePath + " to " + getTmpPath() + ": " +
result.getLogMessage());
} catch (Exception e) {
result = new RemoteOperationResult(e);
Log_OC.e(TAG, "Download of " + mRemotePath + " to " + getTmpPath() + ": " +
result.getLogMessage(), e);
}
// Added this line
result.setFileName(mRemotePath);
return result;
}
UploadRemoteFileOperation.java:
#Override
protected RemoteOperationResult run(OwnCloudClient client) {
RemoteOperationResult result = null;
try {
// / perform the upload
synchronized (mCancellationRequested) {
if (mCancellationRequested.get()) {
throw new OperationCancelledException();
} else {
mPutMethod = new PutMethod(client.getWebdavUri() +
WebdavUtils.encodePath(mRemotePath));
}
}
int status = uploadFile(client);
if (mForbiddenCharsInServer){
result = new RemoteOperationResult(
RemoteOperationResult.ResultCode.INVALID_CHARACTER_DETECT_IN_SERVER);
} else {
result = new RemoteOperationResult(isSuccess(status), status,
(mPutMethod != null ? mPutMethod.getResponseHeaders() : null));
}
} catch (Exception e) {
// TODO something cleaner with cancellations
if (mCancellationRequested.get()) {
result = new RemoteOperationResult(new OperationCancelledException());
} else {
result = new RemoteOperationResult(e);
}
}
// Added this line
result.setFileName(mLocalPath);
return result;
}
