 Posted: Sun Dec 19, 2004 5:54 pm Post subject: [TIP] AMD Athlon64 und tvtime (x86_64-System) |
 |
|
Problem:
tvtime erkennt den AMD Athlon64 Prozessor nicht und aktiviert demzufolge die Erweiterungen MM_ACCEL_X86_MMX
MM_ACCEL_X86_MMEXT
MM_ACCEL_X86_3DNOW
nicht.
Damit es aber bei Verwendung der Motion Adcanced-Filter, speziell Motion Adaptive: Advanced Detection nicht zu einer ruckelnden Bilddarstellung kommt, sind diese notwendig.
Lösung:
HINWEIS: $PORTDIR_OVERLAY und $VERZEICHNIS bitte entsprechend anpassen!
Ich beziehe mich auf tvtime-0.9.13 (dieses unterstützt deutsch), welches sich noch nicht im portage befindet, deshalb machen wir folgendes (als root): | Code: | $ mkdir -p $PORTDIR_OVERLAY/media-tv/tvtime/files
$ cp /usr/portage/media-tv/tvtime/tvtime-0.9.12.ebuild $PORTDIR_OVERLAY[/b]/media-tv/tvtime/tvtime-0.9.13.ebuild |
Nun emergen wir es mit | Code: | | $ emerge --fetchonly tvtime |
Die anschließende Fehlermeldung betreffs der Prüfsumme ignorieren wir hier.
Dann das Archiv in ein $VERZEICHNIS eurer Wahl auspacken.
Nun ersetzen wir den Inhalt der Datei $VERZEICHNIS/src/cpu_accel.c mit folgengem: | Code: | /*

Jetzt erstellen wir das Archiv: | Code: | | $ tar -cjf tvtime-0.9.13.tar.gz $VERZEICHNIS |
Den Rest machen wir als root: | Code: | $ mv tvtime-0.9.13.tar.gz /usr/portage/distfiles/
$ ebuild $PORTDIR_OVERLAY/media-tv/tvtime/tvtime-0.9.13.ebuild digest
$ emerge tvtime |
Fertig.
