Programmwechsel dauert ewig
« am: April 13, 2014, 01:15:31 Nachmittag »
Hallo,

ich benutze neuerding den VLC für DVB-C und habe eine neue channels.conf erstellt, nachdem Unitymedia die Kanalbelegung geändert hat.

Seit ich die neue channels.conf benutze, dauert das Umschalten ewig. Ewig heißt so bis ca 20 Sekunden. Mit der alten channels.conf ging der Programmwechsel schneller.

Der Aufbau der channels.conf hat sich ja nicht geändert, woher kommt diese Verzögerung?

Ist das ein VLC Problem?

Gruß

Sundtek

Falsche Parameter in der Channels.conf?

Das Umschalten geht idR ziemlich schnell mit den Tunern. Wie man auf eine 20 Sekunden Umschaltung kommt wissen nicht mal wir.
Ich nehme an du verwendest noch einen alten Tuner (noch nicht die MediaTV III Serie)?
Bei den Treibern für die alten Geräte hat sich ausser allgemeine Kompatibilität schon sehr lange nichts mehr geändert.

Eventuell Logfile einschalten /opt/bin/mediaclient --logleve=min und /var/log/mediasrv.log überprüfen.

Also lt. lsusb habe ich einen MediaTV Digital Home II mit der Seriennumer 0110314160021

Gut, 20 Sekunden ist vielleicht etwas übertrieben, aber 8-10 Sekunden vergehen mindestens, gefühlt ne Ewigkeit.

Das habe ich aus dem Logfile herausgekitzelt, als ich mal umgeschaltet habe:

Signalprobleme?

Was zeigt denn folgendes an beim Umschalten:
/opt/bin/mediaclient --readsignal=0 -d /dev/dvb/adapter0/frontend0
Failure is a good thing! I'll fix it

Google sagt, dass andere mit VLC auch diese Beobachtung machen, vielleicht ein VLC Problem?

Also beim Umschalten scheint das Signal für eine Sekunde auf 0% zu sinken, das ist der Output, beim Umschalten plus ein paar Sekunden nach dem Umschalten:
