@ -3230,6 +3230,10 @@ Deaktiviert die Anzeige von Bildern.
Benötigt für einwandfreies Benchmarking von Treibern, die den Bildpuffer nur
bei einem Monitor-Retrace ändern (nVidia).
Voreinstellung ist, die Bildwiedergabe nicht zu deaktivieren (nobenchmark).
.IPs (no)bobdeint
Sehr einfacher Deinterlacer.
Sieht m\366glicherweise nicht besser als -vf tfields=1 aus, ist aber
der einzige Deinterlacer, der mit xvmc funktioniert. (Standard: nobobdeint)
.IPs (no)queue
Frames werden in einer Queue angeordnet, um der Videohardware weitergehendes
paralleles Arbeiten zu ermöglichen.

@ -3087,6 +3087,10 @@ Disables image display.
Necessary for proper benchmarking of drivers that change
image buffers on monitor retrace only (nVidia).
Default is not to disable image display (nobenchmark).
.IPs (no)bobdeint
Very simple deinterlacer.
Might not look better than -vf tfields=1,
but it's the only deinterlacer for xvmc (default: nobobdeint).
.IPs (no)queue
Queue frames for display to allow more parallel work of the video hardware.
May add a small (not noticeable) constant A/V desync (default: noqueue).
