Vlc, DVD & rogne… strano il titolo, vero? Allora cerco di spiegarmi: circa un mese fa circa avevo un normale PC fisso con una piastra madre ASRock A-68 C-S con una normale scheda grafica NVidia. Niente di eccezionale. Ma come tutte le cose, anche questa è giunta a fine vita. Al suo posto ho comprato un HP Compaq 8200 Elite SFF in cui ho installato sia il disco rigido con Linux sia la vecchia scheda grafica. Poi mi è toccato duplicare il vecchio disco rigido con uno nuovo. Alla fine piccole cose. Il problema si è manifestato con i DVD. Io sono un appassionato di cinema e di serie televisive, soprattutto orientali e li guardavo abitualmente con il vecchio computer usando Vlc e dvdcss. Il sistema funziona regolarmente, ma Vlc, Kaffeine, KPlayer. quando li uso per guardare i DVD in mio possesso ottengo dei risultati " strani": in pratica Vlc mi mostra circa 30 minuti di filmato, se ma bene, e poi più niente. Sento puzza di bruciato. Visto che ho anche un altro disco rigido sto pensando di installarci una copia di M$ Windows e Vlc e vederne il comportamento. Se per caso usando Windows il DVD mi venisse mostrato nella sua interezza allora siamo in un ambito da giustizia civile, se non erro. Vorrei dei consigli. Comunque domani telefonerò alla persona da cui l’ho acquistato per sentire la sua opinione a riguardo. P.s: testato usando vari masterizzatori/lettori DVD.
Domande varie:
- succede con tutti i dvd?
- hai detto che succede con vari player. Scrivono qualcosa a video se li apri da terminale? Ad es ‘$ vlc’; prova ad installare anche mplayer, giusto per differenziare, e ad aprirlo con ‘$ mplayer dvd://NUMTR’ dove al posto di NUMTR metti ad es 1.
- libdvdread e libdvdcss sono installati?
Ciao, bebo_sudo, grazie per il tuo intervento. Ho provato con DVD di aree 0, 1, 2, 4. Nada. Testato con Vlc, Kaffeine, KPlayer e Mplayer. Le librerie libdvdread e libdvdcss sono installate. Ho provato poco fa da console come da te consigliato e ci sono parecchi indizi. Ti mostro i messaggi:

[1]+ Fermato vlc /dev/cdromChe ne pensi?
P.s: forse è collegato a questo ( https://forum.videolan.org/viewtopic.php?t=85150), ma ciò non avveniva precedentemente…
Tra tutti gli errore visualizzati, quello che spicca è:
Failed setup for format vdpau: hwaccel initialisation returned errorche poi genere a catena anche tutti gli altri errori.
Hai provato ad aggiornare i driver proprietari di nvidia?
Io uso i nouveau, i driver proprietari quando devi fare il cambio di versione fanno penare un pò.
Ultime notizie! Ho effettuato un piccolo esperimento: possiedo una disco rigido con la Fedora 29, è una lunga storia, e l’ho messa al posto della versione attuale, la 30. Cosa è successo? Che di colpo i DVD illeggibili sono diventati leggibili da Vlc. Il problema è di tipo software, c’è un bug… Domanda: ha chi lo segnalo? Fedora o RPM Fusion?
Allora, il problema risiede nella libreria libva. L’attuale versione è se non erro la 1.4.1 mentre quella che non crea problemi nella visione è la oramai vecchia 1.1.1-11. Avvisiamo quelli di Fedora del problema… P.s: ho testato la visione dei DVD usando anche la scheda video integrata nel mio computer invece della mia NVidia. Niente, nada, niet…
Mandato l’avviso del bug alla Fedora. Aspettiamo i risultati. Possiamo anche mettere " risolto" visto che la causa del bug è stata individuata. Grazie a tutti.
Perdona l’intrusione, e se per ora azzardassi un “sudo dnf downgrade libva”?
Già fatto, non funziona perchè manca la versione precedente sulla versione 30. Ho fatto alcune verifiche e il problema si presenta anche al variare delle interfacce d’uscita ( Strumenti|Preferenze|Ingresso/Codificatori|Hardware-accelerated Decoding). Ecco cosa mostra abilitanti Vd-Pau anzichè in automatico:

Non so proprio cosa dire. Intanto Domenica passo alla 31, vediamo cosa succede. Intanto devo aggiornare quelli di RedHat Bugzilla.
P.s: usando o una Fedora 29 che conservo oppure una Mageia 5 che ho nell’altro disco rigido nel mio computer non si presenta il problema a parità d’hardware.
