Compress videofiles from context menu in Windows 11 using ffmpeg
11 janvier 2023, par RayearthI'd looking for an easy way to just right click on a folder in Windows and be able to loop through video files and compress them with ffmpeg with prepared command settings.


Been able to prepare the reg file to import but I think I'm missing something important here (working directory reference I think). How should I pass the working dir path inside a command like that for this mechanism to work ?


Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\Shell\Compress_videos]
@="Compress videos"

[HKEY_CLASSES_ROOT\Directory\Shell\Compress_videos\command]
@="cmd /c for \"%E\" in (.mp4, .mkv, .mov, .avi) do forfiles /m *\"%E\" /c \"cmd /c C:\\Windows\\System32\\ffmpeg.exe -hide_banner -y -hwaccel cuda -i @path -c:v hevc_nvenc -b:v 8000k -c:a copy @fname_compressed.mp4\""

Progress Bar findviewbyid returns null
1er avril 2017, par ziad kiwanHelp me please it’s getting frustrating !
i’m doing a chat application where i’m adding views to a linear layout programmatically each time a user press the send button the code is below :
public void appendToMessageHistory(String id,String uname, String messa,String messageType, final String filepath, String DownloadStatus,boolean internet,int type) {
//TextView tv=new TextView(Messaging.this);

}okay now to the problem when i call the findviewbyid for the progress bar in sendvideomessage ffmpeg onsuccess callback it returns null even though the findviewbyid for the the imageview which is in the same layout it returns the view ! so please tell me what is the problem
public void onSuccess(String message1) {
Log.w("Zipping","Success");
RelativeLayout v = (RelativeLayout) mEssageBox.findViewById(rowid.intValue()); ;
ProgressBar progressBar = (ProgressBar) v.findViewById(R.id.message_entity_Right_progressbar); // this keeps returning null!
ImageView iv = (ImageView) v.findViewById(R.id.message_entity_right_imageview); // returns the view
// progressBar.setVisibility(View.GONE);
Bitmap bitTh = ThumbnailUtils.createVideoThumbnail(ZippedVideoPath, MediaStore.Images.Thumbnails.MINI_KIND);
iv.setImageBitmap(bitTh);
progressBar.setVisibility(View.GONE);
iv.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(ZippedVideoPath));
intent.setDataAndType(Uri.parse(ZippedVideoPath), "video/mp4");
startActivity(intent);
}
});
UploadVideo uv = new UploadVideo(v);
uv.execute();
}Thank you !
