[geloest] Timeshift Problem mit 1.7.x

Hi,

ich mach mal n Thread nur fuer das Problem hier auf:
Bei zentoo auf der SMT friert VDR haeuffig bei Timeshift ein,
zuerst dachte ich das waere eine xineliboutput Problem,
aber seitdem ich gdb und strace auf der Box am laufen hab, sieht
es anders aus.

Auszuloesen ist das Verhalten einfach. Timeshift starten auf USB, z.B.
und ein Paar mal Pause druecken.
Ploetzlich haengt die Box, Standbild keine Menues .....
SVDRP ist auch weg (seltsam)

strace vom VDR:

Hi, hast du der Ext patch eingespielt?
Ich hab bemerkt das, eben mit ausgeschaltenes livebuffer, es problemen geben kann mit dem normalen timeshift.

Komisch bei mir gibts erst Probleme, wenn ich Livebuffer reinpatche. Vorher verhält sich der VDR normal. Naja ich habe auch einen andere Distri.

Mein VDR


VDR4Arch --> Gigabyte GA-MA78LMT-US2H | AMD Sempron 140 | 4GB RAM | 1,5TB HDD | L4M Cine S2 V6.2 | Gigabyte GV-N520SL-1GI

Ich hab den Bug bis in die dvbplayer.c verfolgt, ich verstehe das Problem
noch nicht ganz, aber es sieht so aus.

Irgendwann liest der reader thread ein Paket vom File, und wird es nicht
los, scheinbar, weil der Player thread noch nicht wieder laeuft, oder
weil das Paket keine gueltigen Daten enthaelt.
Danach loopt der thread und gibt auch keine Daten mehr weiter.

Eine Loesung ist es die Daten in dem Fall zu verwerfen, das gibt
einen kurzen Fehler im Bild, aber der thread blockt nicht mehr.

Ich hab den Bug gefunden:

Bei sehr langsamen Medien kann ein Request haengen, was zu einem
Race zwischen dem Reader und dem Player fuehrt. dabei kann
es sowohl zu einem Haenger, wie zu einem Leak kommen:

Hi

von Zeile 56 bis 61 taucht Length und length auf, ist das so richtig ?
Falls ja sind die Variablennamen sehr ungluecklich gewaehlt ...

Ich hab den Bug gefunden:

Bei sehr langsamen Medien kann ein Request haengen, was zu einem
Race zwischen dem Reader und dem Player fuehrt. dabei kann
es sowohl zu einem Haenger, wie zu einem Leak kommen:

Hat das einen bestimmten Grund, 'result' und 'buffer' hier abzufragen? 'free()' ist doch "NULL-proof".

Die letzten 4 Zeilen haben doch unmittelbar vorher durch den Clear()-Aufruf bereits stattgefunden - oder übersehe ich da was?

Auf der VDR-ML gab es eine Meldung, daß diese Änderung Probleme mit vdr-xine macht (siehe http://linuxtv.org/pipermail/vdr/2012-February/025783.html). Ich tendiere daher dazu, diese Änderung wieder Rückgängig zu machen.
Gibt es dagegen Einwände? Oder einen Fix für das vdr-xine Problem?

Wäre schade wenn das wieder zurückgenommen würde - auf ein stabiles Pausieren hatte ich mich schon gefreut. Fix für xine kenne ich leider nicht. Was sagt rnissl dazu ?

ich hab ja so gar keinen plan ob es hier reinpasst :
[BUG] Pause = 100% CPU Auslastung

hat nix damit zu tun ?

Das Pausieren funktioniert in der 1.7.24 unabhängig von dieser Änderung jetzt ordentlich. Sowohl für SD als auch HD. Und es wird auch nicht mehr der Bildschirm mehrere Sekunden schwarz.
Probier's einfach mal aus ;-)

Das eigentliche Problem, das der Patch in diesem Thread fixen soll, konnte ich selber nicht nachvollziehen. Da mir die Änderung aber durchaus plausibel erschien, habe ich sie übernommen. Wenn die nun aber mehr Probleme erzeugt als sie löst, muß ich sie leider wieder entfernen.

Pausieren scheint jetzt zum ersten Mal seit SD-FF-Zeiten wieder zu funktionieren (zumindest mit softhddev und xineliboutput), auch ohne obige Korrektur. Was ist denn jetzt wirklich dafür verantwortlich?

Früher wurde eine Aufnahme gestartet, dann wurde einige Sekunden gewartet, dann die Wiedergabe gestartet, wieder einige Sekunden gewartet und schließlich der "Pause"-Befehl geschickt.
Das stand naturgemäß auf recht tönernen Füßen, denn wenn sich der erwartete Zustand nicht innerhalb der vorgegebenen Zeit eingestellt hat, ging es eben schief.

Ab Version 1.7.24 wird jetzt die Aufnahme und auch gleich die Wiedergabe gestartet. Die Wiedergabe wartet, bis in der Index-Datei mindestens zwei Einträge drin sind und macht dann ein "Goto" zum ersten Frame mit dortigem Standbild. Das läuft anscheinend recht zuverlässig und dauert nur genau so lange, wie es eben braucht. Kein längerer schwarzer Bildschirm mehr und auch keine abgebrochene Wiedergabe, weil die Aufnahme noch nicht so weit ist.
