ContentDescriptor do not accept the pcm?
Hi all
I have the following strange situation: I created player with Datasource to receive the RtpPacket byte array and play with blackberry player. However, to implement this I use SourceStream who must have a few ContentDescriptor:
public class RecvStream implements /*Runnable,*/ PlayerListener { private Player mPlayer; private SendStream mSendStream; private SourceStream mInput= new SourceStream(){ ContentDescriptor mContentDescriptor=new ContentDescriptor("audio/amr"); /* (non-Javadoc) * @see java.io.InputStream#read(byte[], int, int) */ public int read(byte[] b, int offset, int length) throws IOException { int len = 0; return len; } public ContentDescriptor getContentDescriptor() { return mContentDescriptor; } public long getContentLength() { return -1; } public int getSeekType() { return SourceStream.SEEKABLE_TO_START; } public int getTransferSize() { return 320; } public long seek(long where) throws IOException { return where; //throw new IOException("not seekable"); } public long tell() { return 0; } public Control getControl(String controlType) { return null; } public Control[] getControls() { return null; } }; public RecvStream(RtpSession session,SendStream sendStream) { } public void stop() { if (mPlayer == null) return;//nothing to stop mRunning=false; try { if (mPlayer.getState() == Player.STARTED) { mPlayer.stop(); } if (mPlayer.getState() != Player.CLOSED) { mPlayer.close(); } } catch (MediaException e) { } } public void start() { mSession.setTimestampClock(new TimestampClock(){ public int getCurrentTimestamp() { return getCurTs(); } }); try{ mPlayer = Manager.createPlayer(new DataSource (null) { SourceStream[] mStream = {mInput}; public void connect() throws IOException { } public void disconnect() { } public String getContentType() { return mInput.getContentDescriptor().getContentType(); } public SourceStream[] getStreams() { return mStream; } public void start() throws IOException { } public void stop() throws IOException { } public Control getControl(String controlType) { return null; } public Control[] getControls() { return null; } }); mPlayer.addPlayerListener(this); mPlayer.realize(); AudioPathControl lPathCtr = (AudioPathControl) mPlayer.getControl("net.rim.device.api.media.control.AudioPathControl"); lPathCtr.setAudioPath(AudioPathControl.AUDIO_PATH_HANDSET); mPlayer.prefetch(); //if ( DeviceInfo.isSimulator() == false) { //only start player on real device mPlayer.start(); //} }catch (Throwable e){ } } public void playerUpdate(Player arg0, String event, Object eventData) { if (event.equals(PlayerListener.BUFFERING_STARTED)){ mBuffering=true; } else if (event.equals(PlayerListener.DEVICE_UNAVAILABLE)) { //pausing both player and recorder try { //already stooped mPlayer.stop(); mSendStream.getPlayer().stop(); } catch (Throwable e) { } } else if (event == PlayerListener.DEVICE_AVAILABLE) { //starting both player and recorder try { mSendStream.getPlayer().start(); stop(); reset(); start(); } catch (Throwable e) { } } } public int getPlayLevel() { if (mPlayer !=null) { return ((VolumeControl)mPlayer.getControl("VolumeControl")).getLevel(); } else { return 0; } } public void setPlayLevel(int level) { if (mPlayer !=null) { ((VolumeControl)mPlayer.getControl("VolumeControl")).setLevel(level); } } public void enableSpeaker(boolean value) { if (mPlayer == null) return;//just ignore AudioPathControl lPathCtr = (AudioPathControl) mPlayer.getControl ("net.rim.device.api.media.control.AudioPathControl"); try { lPathCtr.setAudioPath(value?AudioPathControl.AUDIO_PATH_HANDSFREE:AudioPathControl.AUDIO_PATH_HANDSET); } catch (Throwable e) { } } public boolean isSpeakerEnabled() { if (mPlayer == null) return false;//just ignore AudioPathControl lPathCtr = (AudioPathControl) mPlayer.getControl("net.rim.device.api.media.control.AudioPathControl"); return lPathCtr.getAudioPath()==AudioPathControl.AUDIO_PATH_HANDSFREE; } public long getPlayerTs() { return mPlayerTs; }
When I try to write ECM/pcm audio or audio/basic for Simulator ContentDescriptor throws MediaException.As I understand that I did something wrong, but how can I give a pcm for ContentDescriptor entry?
Any ideas?
ThanksMSohm , but I already find solution. For that Datasource accepts the pcm (it's weird), but you must write audio/x-pcm not ECM/pcm audio or audio/basic. Before that he was the exception in time of creating player.

The "MyNewServerHostname" server did not accept the certificate.
Hello
I have a server on a Mac mini with OS X 10.11 and a MacBook pro with OS X 10.11 customer who worked very well in the lab. But to put the server on another network necessary to change the name and the IP with the changeip command-line. Now the customer can not get the schooling profile.
On the client, I have install the trusted certificate, and then when I install the profile of education get the following failure message:
The "MyNewServerHostname" server did not accept the certificate.
I already tell a customer to make clean installation, deleted all the old certificate server, stopped the open directory and destroy the OD with the slapconfig command-line - destroyldapserver. And then create a new OD with new certificates, but always the same message failed. Any idea to fix it?
After you rename the server, you must create a new profile of certificate and trust. Did you do that?

Re: Failed on nine L510 Vista admin password - does not accept the admin pass
Hi all
Completely baffled by this one so would appreciate any advice.
I just bought a new Satellite L510 with vista hard disk installation.
I went through the installation process long and eventually got to the point where I could configure my admin account and the name of my computer.
I chose the name of my admin account and typed in the password and confirm the password and named my computer.
Now when I get to the initial Vista logon screen, it does not accept the password I am entered (and confirmed).
This can be a problem with caps lock, as the password was all numbers.
(the password was all numbers and five numbers)
It, however, gives the correct indication for the password that I entered. It does not accept the password.
I would be happy even just redo the installation process, but I have no idea how to do this, because I can't even a quick command-line anywhere.
Help, please!
It's strange. You can log on using a different user name?
In any case to run recovery, you either:
* Press and hold zero during the power upward
* Press F8 before Windows starts to enter the Windows Start Menu, then run recovery of the option "repair your computer". http://APS2.toshiba-tro.de/KB0/HTD9102IR0000R01.htm -
Gamepad - resource conflict do not accept the satellite A110
Satellite A110 do not ACCEPT the JOY STICK. CONFLICT OF RESOURCE WITH THE MOTHER. BOARD OF DIRECTORS
Hello
I guess there is a resource conflict because the game port is not available on the device.
So the joystick device tries to use the resources that are used or reserved for any other device.I wanted to use a joystick on my no Toshiba laptop, but it has not been possible.
It was the same question as on your device. But I was able to use it on the desktop.
I think that support doesn t use laptop a lot because of miniaturization and mobility Office PC port. -

update of sql server 2005 service pack 3 error code 6D9E Windows update security does not accept the update
Hey lasdj,
Thanks for posting in the Microsoft answers site!
If you receive Windows Update error 6d9e while installing SQL Server 2005 Service Pack 3 by using Windows Update, it means that the installation folders and directories are compressed or encrypted.
To fix this problem, make sure the folder locations where you are installing the service pack to aren't compressed or encrypted, or specify a different folder and then run Windows Update again.
Therefore, remove the compression of the DATA directory and run together to the top again.
Remove compression from the C:\Program Files\Microsoft SQL Server folder and see if you are able to install the updates without any problem.
See the links below for more details:

Flight Simulator FS9.cfg file does not accept the changes
I am running Msft FltSim2004 under Windows 7 Professional. I had to make additions to the FS9.cfg file (it takes changes in txt in Notepad). It is a hidden file located in C:\Users\{my name} \AppData\Roaming\Microsoft\FS9. After that I have to make the changes and close the file, and restart FltSim, I still get the error that the change was supposed to eliminate FltSim. When I check FS9.cfg, the change I've made is no longer there.
I changed all the c:\ folder permissions down to FS9, as well as the permissions in the FS9.cfg file. But it still does not accept the changes. Everything else works fine under Win7. Any suggestions? Thanks in advance for your help.
Art
Art,
Try to copy the file to your desktop (or another folder), and then delete one located in the FS9 folder. Make the changes to the copied file and simply save it to the new location. Reopen the case to check the changes remained, and then copy it in the FS9 folder and test. Let us know the results.

Aspire 5749z who do not accept the windows product key, attached to the back of the laptop
I installed Windows 10 House. When I went to enter the enclosed code error codes and not accept the key and activate windows 10
you need to upgrade your version of windows to windows 10 first, then you can do a clean install.
you don't need to enter any 10 windows product key during installation (if you did the upgrade first).
Windows 10 will not accept any product key from older versions of windows if you do a clean install, you must buy a windows retail 10.
