# Individuare il problema

## Ottenere supporto

Ci sono diversi modi per ottenere aiuto con &kplayer;. Se vuoi porre una domanda, il forum utenti è il miglior posto per farlo, poiché altri utenti potranno vedere il messaggio, così come lo sviluppatore che certamente ha sottoscritto la ricezione degli avvisi quando un nuovo messaggio viene inserito. Il forum utente è anche un buon posto per discutere di un problema di cui non si ha sicurezza che sia un bug.

Bugs should be reported through the bug tracking system, following the instructions in the Bug reporting micro-HOWTO. Bugs reported using the Report a bug option on the Help menu are still accepted, but are less helpful.

Also there are special sections at the &kplayer; project on SourceForge for support requests, feature requests and code patches.

## Problemi comuni

### La maggior parte dei comando nel menu e nella barra degli strumenti sono mancanti

The `kplayerui.rc` file was misplaced during installation, and &kplayer; cannot find it. If you installed using a binary package, complain to the package maintainer. When compiling from source, be sure to follow the instructions in the Compilation micro-HOWTO, especially the part about `kde-config`. Before starting, run

``kde-config` `--prefix``

dalla riga di comando per essere sicuri che il percorso prefisso di &kde;.

### Dopo un aggiornamento di &kplayer; le nuove funzionalità sono mancanti

You may have a file called `kplayerui.rc` in `~/.kde/share/apps/kplayer`. Removing it will get you the new menus, but it will also reset any keyboard shortcuts you may have changed in the Key Bindings dialog.

### &kplayer; non viene visualizzato nel sottomenu Multimedia del &kmenu;

Il file `kplayer.desktop` deve essere installato nella corretta posizione, in `share/applnk/Multimedia` o in `share/applications/kde` nella cartella globale di &kde;.

There also may be a file called `kde-kplayer.desktop` in `~/.local/share/applications`. Removing it will get the Multimedia menu updated automatically again when you install or uninstall &kplayer;, but it will also reset changes you made to &kplayer; associations with media types on the File Associations page in &konqueror; configuration dialog or in &kcontrolcenter;.

La scheda Indice in &khelpcenter; dovrebbe elencare anche &kplayer; nella sezione Multimedia sotto Manuali delle applicazioni.

### Impossibile avviare &mplayer;

If you get this error when trying to play a file, you need to install &mplayer; before you can use &kplayer;. This error can also happen if the name of your &mplayer; executable is not `mplayer` or it is not in the current path. In that case go to the Advanced page in &kplayer; Settings and give the executable name or the full path in the Executable path field.

### configure: errore: Impossibile trovare le librerie di X

That means that you are missing the X include files, which normally come with the X development package. So look for a package in your distribution that has files like X.h and XEvent.h. For example, on Debian it is called `xlibs-dev`.

Similarly, if `configure` complains about missing Qt files, you need to find and install the Qt development package. If you look in the `config.log`, it will probably tell you the exact name of the file it couldn't find, somewhere near the bottom. The `config.log` file is quite verbose, so you would have to scroll a few pages up from the bottom to find the place where it reports the error.

### Impossibile riprodurre alcun file

Guardare alla fine del registro messaggi per vedere gli errori che &mplayer; restituisce quando di cerca di riprodurre il file. Premere &Ctrl;L se &kplayer; non mostra automaticamente il registro.

Try playing the files with `mplayer` from the command line. If &mplayer; can play them, compare the options you used on the command line to the ones &kplayer; passed to &mplayer;. Set the required options in &kplayer; Settings. The most important ones are the Driver options on the Video and Audio pages. On the Advanced page check the Executable path option to make sure &kplayer; will be able to find the &mplayer; executable, and if there are any options that are not found anywhere in the &kplayer; Settings dialog, put them in the Additional command line arguments field.

### Impossbile riprodurre uno specifico file

Look at the end of the message log to see what errors &mplayer; gives when trying to play the file. Hit &Ctrl;L if &kplayer; does not show the log automatically.

Try playing the file with `mplayer` from the command line. If &mplayer; can play it, but requires special option to play this particular file, put them in the File Properties for that file. Two options that sometimes help &mplayer; when it cannot detect the file type automatically are `-vc` and `-ac`, which correspond to the Codec options on the Video and Audio pages in File Properties. If there are any options that are not found anywhere in the File Properties dialog, put them in the Additional command line arguments field.

If it is a playlist file but it does not have one of the standard playlist file extensions, go to the General page in the File Properties and set the Playlist option to yes. In rare cases a file that is not a playlist may have a playlist extension. Then you will need to set the Playlist property to no. For more details see the Playlist files section in the Playlist micro-HOWTO.

### Impossibile riprodurre file video

If &kplayer; only plays audio files but not video files, there may be a problem with the video output. By default &kplayer; uses XVideo extension for video output. If the extension is not enabled or is being used by another program like Kino, &kplayer; may not be able to use a different video output. You can either enable the XVideo extension or tell &kplayer; to use another video output. See the Configuration micro-HOWTO for details.

### Il video è riprodotto correttamente, ma non c'è suono

Look in the Message Log to see why &mplayer; cannot play audio. The most common problem is the audio device being locked by another program. In this case the chief suspect is `artsd`. Try running

``killall` artsd`

from the command line. If that helps then the permanent solution is to go to the &kcontrolcenter; and disable &arts;. &arts; and everything based on it is by far the worst part of &kde;. Fortunately it seems there are plans to finally get rid of it in &kde; 4.

Per ulteriori informazioni sulla configurazione audio di &kplayer; vedi il micro-HOWTO Configurazione.

### &kplayer; non può riprodurre un file che viene riprodotto correttamente con &mplayer;

Quando &kplayer; è in Esecuzione o Riproduzione, esegui

``ps` `auxww``

from the command line. Compare the command line options that &kplayer; uses to run &mplayer; to what you are using to play the file with &mplayer;. Then start adding missing options one by one until you get the same problem you are getting in &kplayer;. After you find out what option is causing the problem, you can open the configuration dialog in &kplayer; and remove or change that option. If you need to make the change just for that one file, go to the File Properties instead.

### Impossibile riprodurre un DVD, CD video o CD audio

Scegliere Apri URL dal menu File. Inserire un URL del tipo `dvd://1` o `vcd://1`. Per ulteriori informazioni sulla riproduzione da diversi tipi di dispositivi hardware vedere il micro-HOWTO Dispositivi.

### Problemi al ritorno dalla modalità a schermo intero

If you are getting problems when you try to go back to normal window size from full screen mode, for example the window becomes too large or you are seeing endless flickering, you can try unselecting the Resize main window automatically option on the General page in &kplayer; Settings. Also read the thread about this problem at the &kplayer; user forum and watch it for updates.

### La stazione radio richiede troppo tempo per iniziare la riproduzione

By default &kplayer; uses one megabyte of cache. When playing low bitrate media like a radio station, it will take a long time to fill it. You can choose a lower Cache size setting on the Advanced page either globally in &kplayer; Settings or in the individual File Properties. For more information on playing online media see the Streams micro-HOWTO.

### I file video di grandi dimensioni richiedono troppo tempo per iniziare la riproduzione

You may have set the Cache size option too low in &kplayer; Settings. The default global setting is one megabyte, which should work fine in most cases. If you need to set it higher or lower for an individual file or stream, you can do so on the Advanced page in File Properties.

### &konqueror; o &kmldonkey; mostrano solo l'area del video

If you open a web page with an embedded multimedia object in &konqueror;, only the video area is displayed, with no controls. Same happens when previewing partially downloaded files in &kmldonkey;. It is recommended that you right click the video area and choose the Start &kplayer; command. Playback will then stop, and the full &kplayer; will open up and start playing the file or URL.

### I controlli di contrasto e luminosità non funzionano

È necessario abilitare l'estensione XVideo nella configurazione di X11.

### Impossbile aggiornare kdelibs-data a causa di un conflitto

In Debian il pacchetto `kdelibs-data` contiene il file `rtsp.protocol` , che &kplayer; sostituisce con la propria versione. Se successivamente si prova ad aggiornare il pacchetto `kdelibs-data`, `apt-get` segnalerà un conflitto. Questo è un bug di `apt-get`. Per rimediare, eseguire i seguenti comandi:

``apt-get` remove kplayer`

``apt-get` install kdelibs-data`

``apt-get` install kplayer`

Se esegui ``apt-get` install kdelibs-data` prima di ``apt-get` remove kplayer`, un altro bug di `apt-get` ti impedirà di rimuovere il pacchetto `kplayer`. Una soluzione temporanea è:

``dpkg` `-r` kplayer`

``apt-get` `-f` install`

``apt-get` install kplayer`
