I am trying to use MP4Box to edit the #EXT-X-MAP:URI="fragment_init.mp4" file used in HLS fMP4. My current approach is to dump the mp4 file to an xml file, edit the xml and then package back into an mp4 file. Firstly, the source gstgenerated.mp4 file is converted to 2sec HLS fragments:
MP4Box -dash 2000 -frag 2000 -profile full -out master.m3u8 -segment-name fragment_ gstgenerated.mp4
Then the newly created fragment_init.mp4 file is dumped to the default fragment_init_dump.xml file:
MP4Box -dxml fragment_init.mp4
But if I try to re-create the mp4 file with the -package option an error is generated:
C:\Users\KFerguson\Videos\PAR> MP4Box -package fragment_init_dump.xml -new init.mp4
Missing 4CC code for meta name - please use ABCD:fileName
Failed to package file
Can anyone help with interpreting this and comment if I am on the right path to the box editing objective?

I am getting an error writing a file, that is driving me crazy.
I have an C# netcore 5 application running on RH Linux.
I mounted an shared folder (windows) using: sudo mount -t cifs -o username=MyDomainUsername,password=MyDomainUsernamePassword,domain=MyDomain,dir_mode=0777,file_mode=0777 //ipv4_from_destination/Reports /fileshare/Reports
Then I run the app, using just ./WebApi --urls=http://+:8060
The read/write test executes the following steps:
Create a text file.
Write the text file.
Delete de text file.
Creates a directory
Creates a text file inside that directory
Writes the text file
Deletes the text file
Deletes the directory.
Now the problem:
The text file is created
The write operation fails.
Where goes part of the log:
Creating file: /fileshare/Reports/test.616db7d1-07fb-4599-a0cf-749e6a8b34ec.tmp...Ok

What I discovered so far:
I can create and delete the files and directories.
I cannot write to files.
Can someone give me an hint on this?
Solved using the cifs option nobrl
I have the following short program
from zipfile import ZipFile
procFile1 ="C:\\Temp\\XLFile-Demo.zip"
procFile2 ="C:\\Temp2\\XLFile-Demo-PW123.zip"
# Unencrypted file
print ("Unencrypted file")
myzip1 = ZipFile(procFile1)
print (myzip1.infolist())
myzip1.extractall("C:\\Temp")
# Encrypted File
print ("Encrypted file")
myzip2 = ZipFile(procFile2)
print (myzip2.infolist())
myzip2.setpassword(bytes('123', 'utf-8'))
myzip2.extractall("C:\\Temp2")enter code here
At this Amazon Drive link are the two files. They are identical except that one zip is protected with the password 123.
Executing the above code successfully extracts the unencrypted one but raises the error NotImplementedError: That compression method is not supported for the other.
Unencrypted file
[<ZipInfo filename='XLFile-Demo.xlsx' compress_type=deflate external_attr=0x20 file_size=31964 compress_size=29252>]
Encrypted file
[<ZipInfo filename='XLFile-Demo.xlsx' compress_type=99 external_attr=0x20 file_size=31964 compress_size=29280>]
Am I doing anything wrong from my end?
The error came up when the file was zipped using WinRar's ZIP option. I installed 7Zip and it is working.
The .infolist for the 7Zip file is the following:
[<ZipInfo filename='XLFile-Demo.xlsx' compress_type=deflate external_attr=0x20 file_size=31964 compress_size=29340>]
Incidentally WinRar can handle this file and 7Zip can correctly process the encrypted Zip archive created by WinRar.
I have a website script, it 212MB and it's in RAR format , I could not upload it via filezilla ftp , it gave me a timeout error after sometime, I could not upload it from the filemanager of cpanel as it also kept showing an error. Then I used a php script to upload it directly from the link but now I can not extract it as its RAR not ZIP. I converted the RAR into ZIP and have it on drop box and google drive but there is no direct link which I can use to upload via the php script, SO, Is there any way to extract the rar file from cpanel or using a php script or some other tweak. I have been working on it for 2 hours now and can not find a way around.
create a php file and extra the .rar with that php file. use the following code
$archive = RarArchive::open('archive.rar');
$entries = $archive->getEntries();
foreach ($entries as $entry) {
$entry->extract('/extract/to/this/path');
}
$archive->close();
I'm trying to register a custom file type as a mime-type in linux. My custom filetype, with a custom extension, is actually a zip archive containing various xml and other files.
The problem I'm having is that my operating system (kubuntu) won't recognize the file as my custom mime-type but insists on it being a zip file.
I'm not sure where I should start trying to fix my problem. I've used the following mime info file (tugraz-caleydo.sharedmimeinfo):
<?xml version="1.0" encoding="UTF-8"?>
<mime-info xmlns='http://www.freedesktop.org/standards/shared-mime-info'>
<mime-type type="application/x-cal">
<comment>Caleydo Project</comment>
<glob pattern="*.cal"/>
</mime-type>
</mime-info>
My Desktop Entry (caleydo.desktop, correctly registered in /usr/share/applications):
[Desktop Entry]
Version=2.01
Encoding=UTF-8
Name=Caleydo
GenericName=Data Visualization
Comment=Visualization for Molecular Biology
Exec=/usr/bin/caleydo
Icon=/usr/share/pixmaps/caleydo_256.png
StartupNotify=true
Type=Application
Categories=Science;
MimeType=application/x-cal;
And these are the commands I'm trying to use:
sudo xdg-mime install --mode system tugraz-caleydo.sharedmimeinfo
sudo xdg-mime default caleydo.desktop application/x-cal
sudo update-mime-database /usr/share/mime
However, this still gives me:
$ xdg-mime query filetype export_2012.cal
application/zip
I finally found the issue:
the mime info file has to have exactly the name of the mime type. Renaming it to x-cal.xml did the trick.
I am trying to create a "bks" keystore using keytool (using terminal app on Mac OS X). I am following the instructions in:
keytool error: java.security.KeyStoreException: BKS not found
This is my usage:
keytool -genkeypair -v -alias androiddebugkey -keyalg RSA -keysize 2048 -validity 10000 -keypass android -keystore /Users/djames/dropbox/bc146keystore/debug.keystore -storepass android -storetype BKS -providerclass org.bouncycastle.jce.provider.BouncyCastleProvider –providerpath /Users/djames/dropbox/bc146keystore/bcprov-jdk16-146.jar -dname "CN=Android Debug, OU=Android, O=Android, L=Whitefish, S=MT, C=US"
I am getting the following error:
keytool error: java.lang.RuntimeException: Usage error, ?providerpath is not a legal command
java.lang.RuntimeException: Usage error, ?providerpath is not a legal command
at sun.security.tools.KeyTool.parseArgs(KeyTool.java:375)
I have seen the -provider path option recommended in countless web posts (including the one above) and when I run keytool -help it confirms the syntax is legal:
keytool usage: ...
-genkeypair [-v] [-protected]
[-alias <alias>]
[-keyalg <keyalg>] [-keysize <keysize>]
[-sigalg <sigalg>] [-dname <dname>]
[-validity <valDays>] [-keypass <keypass>]
[-keystore <keystore>] [-storepass <storepass>]
[-storetype <storetype>] [-providername <name>]
[-providerclass <provider_class_name> [-providerarg <arg>]] ...
[-providerpath <pathlist>]
I also tried the following alternative (per http://docs.oracle.com/javase/6/docs/technotes/guides/security/crypto/CryptoSpec.html):
deleting the -providerpath option of the keytool command,
placing the bcprov-jdk16-146.jar inside the {$JAVA_HOME/lib/ext} folder
adding security.provider.3=org.bouncycastle.jce.provider.BouncyCastleProvider to the java.security file.
But it still failed.
Any ideas on what I can do differently to succeed in creating a BKS keystore?
It's many years since, but I am attempting this too.
The answer is that you have the parameters in the wrong order. The -providerpath needs to come before the -providerclass parameter.
I hope that helps someone in future searching for a solution.
I was never able to succeed with Keytool. This is what I did to solve the problem instead: I made a copy of the default debug.keytool (a JKS type keystore) that was created by Eclipse (Indigo, SR2) automatically the first time an android program is run in Eclipse, and used Portecle (http://portecle.sourceforge.net/) to convert this to a BKS type keystore. Now this is the tricky part: If I now used the BKS version of debug.keytool in place of the original, I got an "Android packaging error" in Eclipse “java.io.IOException: Invalid keystore format” whenever I would try to run the android program. However, if I left the original JKS version of debug.keytool in the default directory where Eclipse created it, then I could use the BKS version of the debug.keytool in the Android program's /resources/raw subfolder and have Android open it and recognize it. Jim
An easy alternative is to use Portecle to generate the BKS:
Download the needed Boucycastle Provider
Replace bcprov.jar in your Portecle install directory (example: C:\Program Files (x86)\Portecle\bcprov.jar). Same naming is required.
Restart Portecle and generate your BKS truststore.
More explanations here.
I am trying to do SSL connection with certificates, so to support in Android I need to use jks / bks files as trust store.
So generated jks file tried in android SSLSocket connection, But
throws exception that jks not able to read. So I have to add
Boncycastle provider to JVM and create bks using jks file
Download the Bouncycastle provider jar file and place under below path:
C:\Program Files\Java\jre1.8.0_191\lib\ext
Update the java.security file by adding provider for the following file
C:\Program Files\Java\jre1.8.0_191\lib\security\java.security
Add the provider
security.provider.12=org.bouncycastle.jce.provider.BouncyCastleProvider
Close command prompt and open execute command to get bks file like below:
keytool -importkeystore -srckeystore <input>.jks -destkeystore <required_bks_file_name>.bks -srcstoretype JKS -deststoretype BKS -srcstorepass <jsk file password> -deststorepass <jsk file password> -provider org.bouncycastle.jce.provider.BouncyCastleProvider
Now you can bks file in your folder.
Thanks
